Before we worry too much about the fate of the Standard Model of the universe, it’s worth noting that we are also told that it would be “extremely difficult” to prove that a star is really an anti-star. It’s mainly just an intriguing idea at this point.
Sheldon: This dashes yet another attempt to find something that the standard model could not explain. Surprisingly, this is what depresses particle theorists, who have yet to find anything new in the last 40 years, despite thousands of publications.
Researchers: ” …the neutron has a significantly smaller EDM (electrical dipole moment) than predicted by various theories about why matter remains in the universe” The new find doesn’t answer the question but it enables theories to be winnowed.
We are told that thousands of anti-hydrogen atoms have now been captured and stored, though it isn’t easy.
It sounded like a great idea, no? Frustrating and weird separately but a breakthrough together? Not this one, it seems.
Recently, theoretical physicist Ethan Siegel crossed our screen while making clear why, in his view, a multiverse MUST exist. If we know so little about the actual universe that we can’t answer the title question, what sense does it make to insist that there must be an infinity of universes?
According to the Standard Model of our universe, beginning with the Big Bang, there is no difference between matter and antimatter (although they annihilate each other on contact). Why then do we see all matter, no antimatter? A group of physicists decided to test a new theory: From ScienceDaily: About ten picoseconds after the Big Read More…
