Immediately after the large bang, there was only one pressure. As the universe cooled, this pressure break up into two, then three, and then the 4 forces of right now’s universe. Physicists have lengthy been looking for a grand unified concept that combines every little thing besides gravity into one pressure. Now, a brand new concept does simply that, however with out making predictions that had jinxed earlier makes an attempt.
Of the 4 elementary forces – gravity, electromagnetism, and the weak and robust nuclear forces – experiments at particle colliders have proven that electromagnetism and the weak nuclear pressure develop into one “electroweak” pressure at energies of about 100 gigaelectronvolts (GeV). This takes us again to a few trillionth of a second after the large bang.
“But the query is what occurred after one trillionth of a trillionth of a trillionth of
