State-of-the-art simulations showed how the early cosmos was flooded with massive, incredibly bright stars. And why they're no longer possible today.
The very first stars in the universe may have been roughly 10,000 times the mass of the sun and about 10,000 times larger than the biggest stars today, a reportAs a point of reference, the largest stars today are roughly 100 solar masses, as those stars from a bygone era would no longer be possible. The new paper paints a picture of an early universe teeming with activity.
They showed that complex interactions led to massive star formations that wouldn't be possible today. Unlike similar studies, their investigation focused on cold fronts, fast-moving streams of cold matter. Before star formation started to take place in the cosmos, neutral gas collected and began to clump together. Hydrogen and helium, meanwhile, released heat, allowing clumps of that neutral gas to reach higher densities gradually. Those high-density clumps became very warm and started producing radiation that broke apart the neutral gas and prevented it from fragmenting into smaller clumps. Ultimately, this allowed these clumps to grow into enormous sizes.
