The Big Bang didn't happen
--- Quote ---
The Big Bang Hypothesis - which states the universe has been expanding since it began 14 billion years ago in a hot and dense state - is contradicted by the new James Webb Space Telescope images, writes Eric Lerner.

Just how massive can stars get? Maybe not *quite* as massive as we thought

Strange quark star may have formed from a lucky cosmic merger
--- Quote ---
But there might be a path using strange quarks. By themselves, strange quarks are pretty heavy, and when they're left alone, they rapidly decay into the lighter up and down quarks. When large numbers of quarks group together, however, the physics may change. Physicists have found that strange quarks can bind with up and down quarks to form triplets, known as "strangelets," that might be stable — but only under extreme pressures. Like the pressures one step above a neutron star.
