Astronomy Picture of the Day - Simulation: Formation of the First Stars

Explanation: How did the first stars form? To help find out, the SPHINX computer simulation of star formation in the very early universe was created, some results of which are shown in the featured video. Time since the Big Bang is shown in millions of years on the upper left. Even 100 million years after the Big Bang, matter was spread too uniformly across the cosmos for stars to be born. Besides background radiation, the universe was dark. Soon, slight matter clumps rich in hydrogen gas begin to coalesce into the first stars. In the time-lapse video, purple denotes gas, white denotes light, and gold shows radiation so energetic that it ionizes hydrogen, breaking it up into charged electrons and protons. The gold-colored regions also track the most massive stars that die with powerful supernovas. The inset circle highlights a central region that is becoming a galaxy. The simulation continues until the universe was about 550 million years old. To assess the accuracy of the SPHINX simulations and the assumptions that went into them, the results are not only being compared to current deep observations, but will also be compared with more direct observations of the early universe planned with NASA's pending James Webb Space Telescope.

Just wondering where the stuff that the stars were made of came from.

The stuff must come from where lost socks go.

It came from a huge black hole that exploded. That was the big bang.

So what created the black hole and what caused it to explode?

Didn’t you know? First, there was nothing. Then it exploded and made everything.
Science!

No one has ever seen a star forming.
They can use all the computer programs they can.
There’s no way gas can come together to form a star.
Where would the energy come from?
On top of that, we have gas laws that do not allow gases to come together.
This is all part of the fake evolution theory that scientists push as real.
See once evolution is proven false(no one has proof of it being real),
The only thing left is Creation....

Well that explains that. So if I scattered a bunch of car parts around eventually, say, in a few billion years it’ll form itself into a Buick?

In your case, I’d wait a little longer, maybe you can get the long awaited flying car...

Pretty sure you don’t have to be up there to be outnumbered and surrounded.

Interesting but no one has any idea how stars formed. Gases do not undergo gravitational collapse. They just expand, no matter how much gas there is. It’s an interesting theory like the evolutionary theory that simple proteins can form and magically appear in a membrane together by accident. It’s a simple way to explain things, but pure hokum.
