NASA's Curious Universe: The Mind-bending Math Inside Black Holes

#BlackHoles #NASA #Podcast
Black holes are mysterious, far away, and can bend the fabric of reality itself—but we're learning more about them all the time. Ronald Gamble, a NASA theoretical astrophysicist, uses math, computer coding, and a dash of creativity to peer inside some of the universe's most extreme objects. We'll explore what it would feel like to get pulled into a black hole and what people get wrong about black holes. And we'll answer questions from curious listeners, including, "What would happen if a black hole ate nothing but magnetized material?"

0:01
Hey, space nerds.
0:02
Jacob: This is a special video episode of NASA's podcast, Curious Universe.
0:07
We have so many more stories for you to discover.
0:10
So choose your adventure at NASA.gov/Curious Universe.
0:15
All right, let's go.
0:16
I just want to get straight into the fun stuff.
0:18
So, like, if you and I are in a spaceship and we're headed straight toward
0:22
a black hole.
0:24
Like, what is that going to be like for us?
0:26
Like, what's happening?
0:28
Ronald: It's going to get weird really fast.
0:29
Okay.
0:31
[Music ]
Welcome
0:36
Jacob: Our universe is a wild and wonderful place.
0:39
And in this podcast, NASA is your tour guide.
0:42
I'm your host for today, Jacob Pinter.
0:44
In this episode, buckle up because we're diving into black holes.
0:49
They are some of the most mysterious objects in the universe.
0:54
Ronald Gamble will help us understand what we know about black holes
0:57
and what's left to find out.
1:00
We'll debunk some of the biggest myths about black holes,
1:04
and we'll answer some burning questions sent in by you, the listeners.
What is a black hole
1:10
Ronald Gamble is
1:11
a theoretical astrophysicist at NASA.
1:14
Now, just to set the record straight, he hasn't actually been inside a black hole.
1:18
No one has.
1:19
But as a NASA astrophysicist, Ronald knows
1:22
what's going on in there better than just about anybody.
1:26
Ronald: A black hole is a is a region of space time, right?
1:30
Jacob: Yeah.
1:30
Ronald: You know, space and time where the gravity is kind of so immense,
1:35
where planets, stars, galaxies, smaller
1:38
galaxies, even light, photons, can't escape out.
1:42
And they are very, very complex objects, but they're very simple at the same time.
1:48
Jacob: Now, we still have tons of questions about how black holes work.
1:52
But thanks to physicists like Ronald, we're learning more about them all
1:56
the time.
1:57
Ronald is one of those scientists who is constantly surrounded
2:00
by long strings of numbers.
2:03
Ronald: The best
2:04
way I can describe it research-wise, is if you see ... picture
2:07
Einstein or somebody at a chalkboard writing all these equations, that's
2:11
what I literally do all day.
2:13
A lot of math. It's a lot of science.
2:15
But kind of finding ways to mash those things together.
2:18
Physics, quantum physics,
2:20
electromagnetism, space-time, relativity, all of that
2:24
all together kind of gives you an idea of what's happening around black holes.
2:29
Jacob: The math tells us that as we approach a black hole
2:32
in our hypothetical spaceship, we will pass a point of no return.
2:37
Now, black holes rotate, just like planets or stars.
2:41
And once we get close enough, we start to rotate along with the black hole.
2:46
It's like we're stuck on some kind of interstellar merry-go-round.
2:50
So space-time is literally being dragged around.
2:52
You have no choice.
2:53
Jacob: Okay.
2:53
Ronald: Reality itself is being dragged around the black hole.
2:56
Jacob: Okay.
2:57
Ronald: But as you get closer, then you'll approach something called the event
3:00
horizon. And right on the edge before that,
3:04
if someone were watching you, right? I always make the joke of throwing
3:07
my brother into a black hole. Sorry.
3:10
You’re the tester.
3:11
But he would freeze on the surface.
3:14
There would be a point.
3:14
And we call that an infinite redshift
3:16
surface where the light that's emitted from you stops.
3:20
Jacob: Wow. Ronald: That's it.
3:22
So that's the last image that you will see, right, of us going into the black hole.
3:28
Jacob: From there,
3:29
our trip only gets more bizarre, and probably more scary.
3:33
Depending on the size of the black hole,
3:35
we may go through a process called spaghettification.
3:39
That means the black hole put so much force on us
3:42
that our bodies stretch way out ... like noodles.
3:46
Ronald: We don't know what's inside. Jacob: Sure.
3:48
Ronald: Maybe my old quantum homework is in there.
3:52
You are under a lot of gravitational pressure,
3:54
meaning all of the gravitational force that is a black hole is now on top of you.
3:59
And you’re continuing to fall, fall closer and closer to the singularity or what
4:03
we would then consider the center of the black hole, which again,
4:07
you are falling an infinite amount of space.
4:10
So space-time inside of a black hole behaves very different
4:15
than it does outside.
4:16
Jacob: As we fall toward infinity,
4:18
it may get extremely bright and incredibly hot.
4:23
And then it's like someone flipped a switch.
4:26
No more light.
4:27
And after that, no one knows.
4:31
Ronald: If we could go there, I
4:32
please collect some information and send it back.
How to study black holes
4:37
Jacob: Now, there are some obvious challenges to studying black holes.
4:41
They're far away.
4:42
No light can escape them, and in many ways they're just weird.
4:48
But we manag to learn about them in two main ways:
4:51
We gather observational data, like looking through a telescope.
4:55
We can observe how the stuff around black holes behaves.
4:58
That's because it puts out types of light our eyes can't see,
5:02
including X-rays and radio waves.
5:04
We can study those.
5:06
And then we have theory: using math and physics to unpack what's going on
5:11
in there.
5:12
So black hole researchers actually have a lot to work with.
5:16
And we find black holes all over the universe.
5:19
Some are about the same mass as our sun.
5:22
Others are much, much larger.
5:25
Take our own Milky Way galaxy: in the center,
5:28
which, don't worry, is too far away to cause us harm here on Earth,
5:32
there is a supermassive black hole.
5:34
It's about the mass of 4 million suns, and other black holes are even bigger.
5:40
Ronald Gamble studies black holes
5:42
with a blend of old fashioned math and computer based modeling.
5:46
He knows a dozen different coding languages,
5:48
and he's also a mentor to young scientists trying to break into the field.
5:52
So I wanted to back up and hear where he started.
5:56
I was hoping that you can tell me kind of your superhero origin story.
6:01
Like, when did you realize that astrophysics
6:04
and black holes were going to be, like, your thing?
6:08
Ronald: My mom would say four years old.
6:11
I would say there's a villain arc in there somewhere.
6:14
But, yeah, four years old, I'm in front of my solar system.
6:18
A little placemat.
6:19
Probably tossin’ my mashed potatoes somewhere
6:22
and I'm asking my mom “does the Sun have fire?”
6:24
So, at four years old.
6:26
So I'm like, Okay.
6:27
She's like, okay, I need for you to be in camps somewhere.
6:30
I watched Carl Sagan, I watched Bill Nye,
6:34
and then things like Magic School Bus, it just kept getting more curious
6:39
and more curious, and I kept asking more questions.
6:43
So that's how I got into it.
6:44
And then I discovered all the things that we didn't know.
6:46
Jacob: Yeah. Ronald: about the universe.
6:48
I'm like, Okay, well, I'm going to study those. Jacob:Yeah.
6:50
Ronald: What's dark matter?
6:51
What's dark energy? What's ... There's new stuff about black holes
6:54
we have to discover.
6:55
So that's, that's how I'm in this.
6:58
It's a lot of fun.
6:59
Jacob: I think a lot of us have a hard time picturing
7:02
how researching black holes actually works.
7:06
Like, I'm not very good at math, if I'm honest, I can't code.
7:08
I'm just wondering if you can kind of put me in your shoes for, like,
7:12
a typical day or a typical project.
7:15
Ronald: Yeah.
7:16
So right now I'm working on a code
7:21
that's going to describe or simulate how high energy particles like electrons
7:26
kind of rotate around the black hole and then get blasted off in a jet.
7:29
Jacob: Okay. Yeah.
7:30
Ronald: So part of that work involves looking at plasma physics.
7:33
It looks looking at
7:36
kind of numerical calculus.
7:38
So that’s kind of doing calculus on the computer.
7:40
But then also, how do I incorporate
7:43
those very theoretical things with the observational data?
7:46
Jacob: Yeah. So tell me more about like that, that
7:50
that difference of that breakdown between observational and theoretical.
7:54
Because I think, again, for those of us on the outside,
7:57
black holes are just so
8:00
they're so spooky and so mysterious that it's it can be hard for us
8:04
to tell what we have observed, you know, in the data for sure.
8:09
And then what people like you are theorizing in,
8:12
you know, in your through math equations on your chalkboard and so forth.
8:16
Ronald: Yeah. So we have to ...
8:19
The first thing I'll say is black holes are actually very simple.
8:21
So we only need about three or four numbers to actually describe a black hole.
8:26
Mass, spin, might be the area of the event horizon.
8:30
Right. And the charge.
8:33
So black holes do have some charge on the surface, but that's it.
8:37
Jacob: Charge like positive, negative? Ronald: Positive or negative,
8:40
you can think of a charge collecting around a black hole.
8:43
Kind of like static charge. Well, it's collecting up, right?
8:45
But those four numbers are kind of what
8:49
we use to kind of funnel in our observational data.
8:53
And then how do folks like you take that and kind of run with it and theorize, you know?
8:58
Ronald: We do... Jacob: the next part. Ronald: what's called bad math, and then we correct with good math
9:04
that's called modeling.
9:05
So we, we work to kind of fill in the gaps for that observational data
9:09
and we again, it's as simple as turning the crank on the math.
relativistic jets
9:12
Jacob: As we keep cranking through the math,
9:15
we're finding new ways that black holes can surprise us.
9:19
Once matter or light falls into a black hole, it doesn't come out.
9:23
That's what makes them black.
9:25
But just outside the black hole, there's a swirling disk of hot, bright gas.
9:31
Most of that gas ends up inside the black hole, but not all of it.
9:36
Some of the gas shoots off, racing away at almost the speed of light in a stream
9:41
that can be incredibly long, like millions of light years.
9:46
Those streams are called relativistic jets.
9:49
And when one of those jets happens to point straight at Earth,
9:52
we give it a special name:
9:54
Blazar!
9:55
Ronald: You can think of them as kind of black-hole lasers or lighthouses.
9:58
Jacob: Okay. Ronald: Right?
9:59
So they're coming not inside the black hole because nothing can come out.
10:02
Jacob: Yeah Ronald: But they're coming right off the surface.
10:04
Right?
10:05
Part of the reason why they get blasted off is due to the magnetic
10:09
fields around black holes, and there's hot plasma
10:12
and everything kind of circling around like a soup.
10:15
Eventually it will spew out and that is what a jet is.
10:19
There are still unknown questions as to why the black hole spews a jet out
10:25
and why these particles go from zero to light speed in an instant.
10:29
Jacob: Wow. Ronald: Yeah.
10:30
So that's part of my research: trying to figure out the why.
10:33
Jacob: Maybe this is a weird question.
10:35
You tell me, but do you have a favorite black hole?
10:38
Ronald: I do, yeah.
10:40
Yeah. So, well I have
10:42
two favorites right now. Jacob: Okay.
10:44
Ronald: One is – and I'm going to give you the catalog name–
10:48
Jacob: Please.
10:48
Ronald: We don't have formal names. Jacob: I'll, I'll look it up.
10:50
Ronald: One is M87. So you might have heard about
10:52
M87
10:53
Sag A*, is the black hole at the center of our galaxy,
10:56
but M87 is kind of a, what I call a well-behaved black hole
10:59
Jacob: Okay. Ronald: It’s playing nice.
11:00
It’s very tilted at a nice angle for us to observe.
11:03
Jacob: Okay.
11:03
Ronald: Giving us great data, but the other one
11:06
is called TSX 0506 +056.
11:09
Jacob: Okay. Ronald: That's a lot of stuff there. Jacob: Sure.
11:12
Ronald: But it is a very high energetic,
11:14
very variable blazar that is giving us weird data.
11:19
It's blowing everything off the charts.
11:21
It's very ... it's extremely bright.
11:23
It's one of the brightest things you might see in the sky.
11:25
Jacob:Wow. Ronald: With your telescope, Of course.
11:27
Jacob: Sure. Sure. Ronald: It’s very far away, but
11:29
It is giving us some really cool data, some really cool physics.
11:32
Jacob: Cool.
11:34
You know, black holes are super, super popular.
11:37
Like we get questions about black holes
11:39
all the time, which we're going to ask you a few of.
11:40
But it makes me wonder, are there any misconceptions
11:44
about black holes that you hear a lot that you keep having to clear up?
11:48
Ronald: I’m so glad you asked. Jacob: Yeah.
11:50
Ronald: One of the ... one of the ... I would say the the most widely known misconception
11:56
is when you type in black hole on Google and you might see like a funnel picture.
12:00
Jacob:Yeah. Ronald: Black holes are spheres. Jacob: Okay.
12:03
Ronald: So they're not a funnel. Jacob:Yeah.
12:04
Ronald: You can’t just fall into it.
12:07
It is it's a sphere.
12:08
So and not only is it a sphere, it's not a perfect sphere,
12:12
so it’s kind of flattened at the poles because it rotates so fast.
12:15
So you can think of it as kind of like a very fat football, right?
12:19
Jacob: Yeah. Okay. Ronald: Or an egg shape.
12:20
Jacob: Okay.
12:21
Ronald: From the top down, it looks like a circle.
12:24
It's got that symmetry, But from the side, it's flattened.
12:27
Jacob: Huh,wow.
12:28
Ronald: Yeah. Jacob: Trippy.
12:29
Ronald: Yeah.
12:31
[Music]
listener questions
12:37
Jacob: When it comes to black holes
12:38
Ronald is curious about pretty much everything.
12:41
But here on this show, we also like to know what you're curious about.
12:45
We want to hear what questions you would ask a NASA expert.
12:49
And it turns out a lot of you were curious about black holes.
12:52
So we picked some of our favorite listener questions
12:55
and I put Ronald in the hot seat.
12:58
The first question came from Ashley.
13:00
They listened to a previous episode of Curious Universe
13:03
called Inside a Black Hole.
13:05
In that episode,
13:06
we mentioned a quantum physics phenomenon called Hawking radiation.
13:10
It's named after the famous physicist Stephen Hawking.
13:13
The idea is that little by little black holes can actually evaporate,
13:18
although it would take something like trillions of years to disappear
13:21
completely, which is an almost impossibly long amount of time.
13:24
Anyway, Ashley wanted to know more about Hawking radiation,
13:28
and they also asked how a star or planet can orbit a black hole.
13:32
How can the black hole's gravity hold something in place?
13:35
Because wouldn't it simply suck in the planet
13:38
or star?
Hawking radiation
13:39
Ronald: Okay, so this is a two-parter
13:41
Jacob:Yeah, Ronald: Well, we can talk about Hawking radiation first
13:44
Jacob:Okay. Ronald: Because that's the fun one.
13:48
Without going into
13:49
too deep in the weeds for quantum field theory
13:52
hawking radiation, it is a quantum effect, but you are kind of looking at
13:57
what the thermal properties of the horizon looks like.
14:02
Right? So if I'm zooming in, not on the large scale, where planets, stars
14:05
and things get pulled in, but on the very, very small scale,
14:08
the particle scale, well, what happens around the black hole?
14:12
Some particles may fall in, some may get kicked out.
14:15
So we're now going more fundamental to the laws of thermodynamics.
14:19
Okay.
14:19
As they apply to black holes, hawking radiation is kind of an effect
14:24
of one of those laws where the entropy of a black hole cannot decrease.
14:29
But on the surface, what happens?
14:31
Well, that information can't get lost because it's in our universe.
14:34
Jacob: Okay
14:34
Ronald: We should still have access to it, but it gets thermally radiated.
14:38
Right.
14:38
But as you kind of radiate away, you're taking some energy away
14:42
from the black hole.
14:43
Eventually, that black hole area, it will shrink.
14:47
Jacob: Okay.
14:47
Ronald: The surface area should shrink and if it keeps doing and it keeps doing that,
14:50
the black hole will theoretically evaporate due to hawking radiation.
14:55
Now that timescales on the order of like
14:58
I don’t know,maybe 10 to the 64 years,
15:01
that's a long range.
15:02
Jacob: So don't wait, don't wait up. Ronald: Don’t wait around for it
15:05
But that's hawking radiation in a nutshell.
15:07
Jacob: Okay. Yeah, I understood that. I'm with you.
15:10
I'm tracking.
15:11
So let me let me get to the second part of her question, though, to make sure
15:14
Ashley walks away happy, She asked how a star or a planet can orbit a black hole.
15:19
Wouldn't the black hole simply suck in the planet or star?
15:22
Ronald: Not necessarily.
15:23
So it's kind of like the how the moon doesn't necessarily fall in towards the Earth
15:27
Jacob: Sure
15:28
Even though it's locked to the gravity of the Earth.
15:31
It carries enough angular momentum, enough spin
15:34
to orbit around the Earth and stay in that orbit.
15:37
So within the accretion disks of black holes.
15:40
You could have solar systems, you can have a bunch of ...
15:43
you could have thousands of stars,
15:44
especially supermassive black holes at the centers of galaxies.
15:47
They're just going to continue to kind of orbit around and orbit around.
15:50
They do pick up some heat, some speed and eventually the force of gravity
15:55
of the tidal forces, if you will, they will start to shred that star apart.
15:59
Well, and then and eventually it will fall into a black hole.
16:02
Black holes don't necessarily suck things in, they kind of pull them.
16:07
Jacob: I hope that answers Ashley's question.
16:09
All right, let's go to number two.
16:10
This is from Tijana.
16:12
“How do scientists at NASA overcome the challenges of studying
16:16
the vastness of space and gathering data from such distant objects?”
16:21
Ronald: That’s a very big question, Jacob: That’s a big question, yeah.
16:25
Ronald: I would say so.
16:25
Just like the podcast,we get curious. Jacob: Yeah. Ronald: Righ?
16:28
We get curious and we get creative.
16:30
So part of being an astronomer, an astrophysicist
16:34
and doing the work from the ground
16:36
and you're looking at things millions of light years away.
16:38
You have to get creative.
16:40
The universe is only sending us
16:42
a little bit teeny bit of information.
16:45
And what are we doing with that information?
16:47
Well, we're building things like Roman, James Webb, Habitable Worlds observatories
16:51
coming up, LISA, things like that, to gather
16:55
those little bits of information that we can get to give us large science.
16:59
So we are making giant leaps and bounds.
17:04
but part of that is getting younger people to get more interested in the science.
17:09
Give us more creative thoughts. Jacob: Yeah. Ronald: Right?
17:12
We need a diversity of thought
17:13
to kind of do NASA science and that's how we get it done.
17:16
Jacob: Yeah, great.
17:17
Well, here's our next question.
17:18
This one is from Rusty.
17:20
This is the one I'm most looking forward to.
Rusty Ashley
17:23
Rusty: Hello, my name is
17:24
Rusty Ashley, and I live close to Austin, Texas.
17:27
And my curiosity is if magnets were created in the Big Bang
17:31
and also what would happen if a black hole only
17:34
consumed magnetized material and nothing else?
17:37
Would that change their fundamental behavior in any way
17:41
compared to normal black holes?
17:44
Thank you.
Common Misconceptions
17:45
Ronald: So here's a common misconception.
17:47
Yeah, black holes actually only consume magnetized material.
17:51
Jacob: Oh!
17:52
Ronald: Because it's technically a plasma.
17:54
Jacob: Okay. Ronald: Which is magnetized.
17:55
Jacob: Okay Ronald: So if you take anything that has charge
17:58
and you’re rotating around in an orbit, it will create a magnetic field.
18:02
Jacob: Okay, Ronald: That's physics 101. Jacob: Yeah.
18:04
Ronald: So pretty much you can think of everything that falls in is kind of magnetized
18:08
to some extent.
18:09
now magnets being created at the Big Bang?
18:14
That is, that's an interesting question because one of the questions
18:18
that astrophysics ask is, well, where did all the magnetic fields come from?
18:23
From objects.
18:24
Things like pulsars, magnetars, which you can think of, like as a magnetic star.
18:29
Those are the strongest magnetic fields in the universe.
18:32
where do these things come from?
18:35
You have to go more fundamental than that.
18:36
So you have to look at the four fundamental forces of nature.
18:40
gravity, electromagnetism and the strong and weak nuclear forces.
18:44
All of those together have to combine.
18:45
They kind of squish together, right?
18:47
They kind of create a soup to give us things that do create magnetic fields.
18:52
There's a lot of physics
18:53
involved in the background, so I can't give you, like, the complete.
18:57
Jacob: Yeah, Ronald: big-picture cosmological answer, but
19:01
that’s why we have a field called physical cosmology.
19:04
Jacob: Okay.
19:04
Ronald: So that we can discover some of those things in the early universe.
19:08
Jacob: So the short answer is ... Ronald: The short answer is
19:09
Jacob: Stay tuned? Ronald: Stay tuned!
19:12
there's a Nobel Prize somewhere
19:13
Jacob: That's right.
19:17
so before we wrap up, there's a couple other things I want to ask you about.
19:21
One of them is art, because I have seen,
19:24
like art and graphics that you've made,
19:27
and I was just blown away like they were really good.
19:30
Ronald: Thanks. Jacob: How did you get started doing that?
19:32
Like, what is that side of you
19:33
Ronald: I have been probably doing art since I was a kid. In undergrad,
19:38
I majored, double majored in physics and fine art.
19:40
Jacob: Wow. Ronald: So I have a minor in fine arts.
19:42
Jacob: Okay.
19:42
Ronald: But it helps to kind of combine left and right brains.
19:45
Jacob: Yeah. Ronald: For me, I couldn't separate them
19:48
and it really helps kind of visualizing the science. Helps
19:51
you learn better to really visualize some of these complex things.
19:55
What is a, how do I draw a black hole?
19:57
Well, again, it's a sphere, but pinch it maybe.
20:00
Jacob: Yeah. Ronald: Right?
20:02
So it's those things, and then the math comes into play, right?
20:06
Jacob: Yeah. Ronald: Thank you, Pythagorean theorem.
20:08
for giving us triangles.
20:11
Jacob: I'm always really curious how people who are really good at science
20:14
bring in, like all of the rest of their lives into
20:18
that, like all of their other interests and the way that they tackle problems.
20:21
Like, do you think that being an artist or being interested in art
20:25
makes you a better scientist?
20:27
How do you how do you see that? Ronald: I think it does.
20:29
So, it ... me being in theory, I have to come up with new physics
20:34
or new ways to describe physics in very creative ways.
20:38
We have a finite amount of math and physics that we've discovered so far.
20:42
Jacob: Sure. Ronald: So we have to use it all, right?
20:44
So it's again, like a kind of
20:49
a chalkboard.
20:49
It's like a blank canvas for me.
20:51
You know. Well, I got to start from scratch.
20:54
I'm like, okay, well, one equation, it's like a Lego, and if I keep stacking,
20:57
I might build, you know, a DeLorean or
21:01
the Millenium Falcon or something.
21:03
And that's what we get.
21:04
And then I can break it apart and make something else.
21:07
Jacob: Yeah.
21:08
Ronald: And so I think being a good theorist, being a good scientist
21:12
requires an amount of right-brain creativity.
21:15
Jacob: Yeah.
21:16
Ronald: I think you need a very holistic view of science and how we do it.
21:20
Jacob: Yeah. Ronald: To be really creative. That's how you get the new stuff.
21:22
Jacob: Yeah Ronald: Yeah. Jacob: I know that
21:25
something else that's a big part of your job and I assume
21:29
just kind of like a passion project too, is, is mentoring people.
21:32
Why is that so important to you?
21:36
Ronald: My kind of mantra is kind of providing
21:39
the ... providing the world what I needed most when I didn't receive it.
21:44
So it's, mentoring to me is is giving the student,
21:48
you know, that that push, that motivation that inspiration, the recommendation
21:55
for lack of better words, the mentorship.
21:57
Jacob:Yeah, Ronald: Right? And the advocacy.
21:59
Some somebody in your corner cheering you on.
22:02
Right? Because I didn't have many mentors like that.
22:04
I had my few and they were fantastic.
22:08
But again, I didn't have many peers kind of doing that, right?
22:14
and then, you know, how do you build that confidence in.
22:17
In the field?
22:17
Astronomy and astrophysics is very ...
22:20
it can be very intense. Jacob: Yeah. Ronald: If you don't know how to navigate it.
22:22
So that's why I like to do mentorship.
22:25
Jacob: Yeah.
22:26
What is something that
22:28
that either early career scientists or students
22:33
or even kids should understand about your job
22:37
and what it takes to be successful in the kind of work that you do?
22:42
Ronald: It's plain and simple: don't stop.
22:44
And I would say like, don't stop, get it get it, but
22:50
quite literally, just don't stop.
22:52
Yes, there are going to be tons and tons of people that will tell you,
22:55
maybe you should choose something else that's a little bit more ...
22:57
you can be successful at it.
23:01
Or, or the likelihood of you being at NASA is actually very low.
23:05
Well, the likelihood of you actually getting NASA's not zero.
23:08
Jacob: Yeah. Ronald: Do it.
23:09
Jacob: Yeah.
23:09
Ronald: So that's the first very first thing I tell people.
23:15
Every talk that I give, I'm giving them.
23:16
Okay, this is where I started from.
23:18
If, if I could get out of here, you can get here too
23:23
But another thing
23:24
I will say is that again, not only just, you know, not stopping
23:29
but also not getting in the way of yourself.
23:32
and that, again, will drive you to keep doing it.
23:34
If you don't get it the first time, you might get it
23:36
the second, third, fourth, fifth, sixth time.
23:40
Right?
23:40
So I've applied to NASA, I think maybe four times.
23:43
Jacob: Wow. Ronald: And so you just have to keep being resilient and it will come.
23:47
You're like, if you keep working on your dreams, they will become reality.
23:52
Jacob: Ron Gamble, thank you so much.
23:53
This was so fun.
23:54
Ronald: Thanks,thanks for having me.
23:57
[Music plays in background] Jacob: Among his many titles, Ronald Gamble
24:00
is the director of a NASA program called Cosmic Pathfinders.
24:04
That's one way for students
24:05
or early-career scientists to get involved with NASA science.
24:09
And when it comes to black holes, there is a lot more to learn.
24:13
You can find more about NASA's black hole research at
24:16

24:19
And if you just scroll back through the Curious Universe feed,
24:22
you'll find an episode called Inside a Black Hole.
24:26
We would love to know
24:26
what you're curious about, about black holes or anything else.
