Clearly you can see black holes are flat like the earth and all other celestial bodies. Rejoice!

You're actually closer to being correct with the assertion the hole is flat than you are about the planet. In theory the singularity is an infinitely small point in space. As such it has no shape. So it might as well be called flat as anything else.

Very cool. What are those? A vacuum of a dead star or something much more complex? I know nothing of them.

Black holes happen when a star ten times the size of the sun run out of lighter elements. The resulting mass of the star, without enough heat to keep it propped up, contracts and becomes more dense.

Our sun, which is about twice as large as the average star, will eventually compress into a ball of iron, a white dwarf about 11 miles in diameter. It isn't big enough to go nova or supernova.

Between the sun and stars up to ten times our sun, when the fire goes out, the star collapses into something even more strange: a neutron star.

Now, while our sun is twice the size of the average star, it's still just a firecracker next to an H-Bomb, because many stars out there are far larger! And when those fires go out, it collapses into a black hole. Something we really do not fully understand, yet. It's black, because any light hitting it can't reflect back to us. The light we do see, here, is from the gas swirling around it getting pulled in. It gets super compressed and heated and glows.

There's a whole bunch more, I could go on for ages about this stuff.

I remember when they first started talking about this, they were supposed to also photograph sagittarius A*. Any idea what happened with that? I would imagine it being 2500 times closer, even with it being smaller, the resolution of the disc should be better. Maybe the interstellar dust cloud made it too difficult to capture?

They may have got the data. Keep in mind that even with access to supercomputers to crunch the data, it took two years to do the processing on this after they got the data!

Surrounded by libetards.
If energy is never destroyed where does it go? Do SMBH's eventually use all that energy to birth another solar system? Is it just a cycle of destruction and rebirth? The universe in a nutshell is the limit of my understanding.....and I use understanding loosely. Hawking was not writing for people with IQ's below 150 imho.

^^^bingo...

She certainly did help, but I think the media is really hyping her up while ignoring the other key contributors. Andrew Chael wrote a majority of the code.

I still get “brain trips” thinking about:

-how the images/stars/etc... that we are seeing now, are actually “x” years old by the time the light travels and is observed here on Earth.

-that space is infinite

-scale, the computer models that show earth, then zoom out to our sun, and then continue to zoom out 15 more times for even larger celestial objects

-time not being totaly linear

A white male wrote 850K of the 900K lines of code and everyone is giving the credit to the female. Total bullshit, but expected.

Especially for an algorithm like this, not every line is code. He’s obviously smart and deserving, but a “line” is not necessarily code. A couple thousand lines from one coder can have more actual code than a hundred thousand lines from someone else.

Nonetheless, this is amazing lol.

Fun fact kinda related but kinda not....

The guy in the first video explaining the black hole in Canadian. He's got an engineering ring on his pinky.

I love to remind people that time is relative. One day on earth is not the same as a year calculated on another planet using the same scale as earth. Time is a calculation based on our orbit and rotation. When you take earth out of the equation, as well as all other planetary bodies, time does not really exist.

Someone will pop in and remind me about the speed of light, and the speed of sound, etc shortly. Even those things are measured by the hour, using the earth as a standard foundation.

Welcome to eternity.

time doesn't exist, nor is the universe governed by it...its a man made concept and the only thing that governs the universe is physics.

Understood and thanks for that. I must have read up on these a long time ago then to even get within a ballpark with my guess.

Yeah, we are pretty insignificant in the grand scheme of things.
