Sep 9, 2023
Assertion Supported
COBE map proved the early universe was not uniform
“Our map showed pink and blue blobs across the entire sky. It's very blurry, but it was enough to say, The early universe was not the same everywhere. There were hot and cold spots.”

What-if
Without early universe density variations, gravity could not form galaxies
“If the universe had been completely exactly uniform, gravity wouldn't know what to do. It would not have any way to pull material back together again. To stop the expansion locally and make galaxies and stars and planets and people.”
