New simulations suggest stars in the early universe were packed so tightly they kept colliding, Space.com reports. Slow collisions led to repeated mergers, building single monster stars that could collapse into oversized black holes, seeds for the first supermassive ones.
That could explain how JWST keeps finding supermassive black holes less than a billion years after the Big Bang, and the strange “Little Red Dots.” UCLA’s Claire Williams: stars can merge “until they form one gigantic star with a mass equal to that of an entire cluster.”
Today’s galaxy cores don’t do this, because the supermassive black holes already there speed stars up, so collisions just destroy them.
My take
JWST keeps breaking the timeline, and the theories are scrambling to catch up. I love it.
God Bless, and Use the Source!
