Neil Tyson - How We Know Black Holes Exist?

The amazing phenomena of the Universe. I have to say, the parallels are remarkable. For instance, a drain spiral, whirlpools, tornadoes. Simply, amazing connections.

Can you imagine if you were able to film being sucked into a black hole? The visuals alone would be bananas. The scariest and most interesting phenomenon in existence.

[cheegum]

Supermassive black hole is coincidentally also the name of my tummy where things go to disappear forever

[DeanToledano]

Guys it's me, I came from that black hole. People aren't nice there, they hate the Teen Titans.

[jaybx]

Everything is somehow connected it’s crazy I wouldn’t be surprised if there’s a version of black holes at the planck length the universe is so fucking cool I wanna learn and discover and study it as a job idk how to even start that tho.

[kamoteph]

what if it's a giant toilet bowl?😂

[caflings]

When 'big' and 'small' are used to describe the same thing, you vet I and a company if people will be confussed.

[John--]

I'd love to learn physics and astrophysics in my spare time but I don't even know where to begin.

[stephenbrickwood]

Gravity must have been very big in the beginning.

[YoungGandalf]

Maybe there are tiny black holes at the centers of hurricanes.

[tassochristopoulos]

Didn't understand a freaking word .... 😮

[stephenbrickwood]

What could have been more forceful than gravity in the beginning ? 😊

[dwatson]

We are in a bathtub and the center of the galaxy is the drain, it’s just a big tornado in the bathtub

You can see a Black Hole. “Today most astronomers believe that quasars, radio galaxies and the centres of so-called active galaxies just are different views of more or less the same phenomenon: a black hole with energetic jets beaming out from two sides. When the beam is directed towards us we see the bright lighthouse of a quasar.”
Quasars are incredibly bright and distant objects. I photographed one that’s over 8 billion light years away.

Because it's actually large but the gravitational effects makes it appear small

[mikecroly]

Thank you so very much dear Mr Neal DE Grasse Tyson! It's mucho wonderful to hear/ see you explain our limits of human knowledge! ❤

[tfluxnjosh]

what if all of the universe is a supermassive blackhole whose horizon we can't see?

[BlackIce]

pretty sure were literally inside a black hole

[markcampbell]

Gravity is defined by mass and velocity. Einstein general theory of relativity defined gravity as Mass velocity. The gravity of an object is not just mass but mass and velocity.

when I first hesrd about the dark thing we are spinning around, the first thing I thought it could be was a masdive black hole... it's what makes sense.
