"A virtual Universe"; a short video not to be missed.

Apologies to n2doc if he has already has an OP on the above topic;

This video is the formal and narrated video showing what the Big Bang looks like from a 12 million years after the event (if there was such one as new theories are postulating) to present day.

They used a 350 million light years across "large enough to be representative of the universe but detailed enough to show great detail" than previous attempts.

The video shows both "the light matter we can see and the dark matter we can't".

The biggest problem was how to produce many differently shaped galaxies for the 40,000 ones depicted.

From the website of the makers of the video, which is pretty much 'a making of...;

"The Illustris project is a large cosmological simulation of galaxy formation, completed in late 2013, using a state of the art numerical code and a comprehensive physical model. Building on several years of effort by members of the collaboration, the Illustris simulation represents an unprecedented combination of high resolution, total volume, and physical fidelity. The About page contains detailed descriptions of the project, for both the general public and researchers in the field.

On this website we present the scientific motivation behind the project, a list of the collaboration members, key results and references, movies and images created from the simulation data, information on upcoming public data access, and tools for interactive data exploration. The short video below is a compilation made from some of the movies available on the Media page."

I have to say this made my day, well, sort of, but it was a welcome respite after doing yard work all day.

2. Well, it certainly is better than yard work.

But 435 MLY is a mere tiny corner of a universe which is likely 90-some GLY in diameter, some 20,000 times the size, or maybe much more.

Thanks.

3. Dunno, I sort of envision the early universe

as novae going off like a gaggle of photographers at a red carpet event as the first stars that formed contained too much mass to be stable, the explosions pushing ordinary matter outward, stretching time and space along with it.

It's a nice, restful little video.

4. Where did the universe come from?

The universe might explain where life evolved...but where did the universe come from?

5. The universe was sneezed according to the Jatravartids

Jatravartids are small blue creatures of the planet Viltvodle VI with more than fifty arms each. They are therefore unique in being the only race in history to have invented aerosol deodorant before the wheel.

Many races believe that the Universe was created by some sort of god or in the Big Bang. The Jatravartids, however, believe that the Universe was sneezed out of the nose of a being called the Great Green Arkleseizure. They live in perpetual fear of the time they call "The Coming of the Great White Handkerchief" (their version of the End of the Universe). The theory of the Great Green Arkleseizure is not widely accepted outside Viltvodle VI.
