I'm surprised no one has posted this already, considering that we are usually quick to announce the passing of major figures in science. Or maybe I missed it somewhere in this forum. J. Robert Schrieffer, the "S" in BCS theory of superconductivity, has passed away this past July at the age of...

Is the likelihood (or unlikelihood) of a Big Rip changed by the new findings of faster universe expansion (https://www.sciencedaily.com/releases/2019/04/190425104128.htm). In https://www.physicsforums.com/threads/will-the-big-rip-basically-be-the-big-bang-for-the-next-universe.971039/, phinds...

I was reading that the Big Rip will cause the whole universe to go singular, which sounds to me like another Big Bang. I was reading up on the Big Rip at Wikipedia, where it says that the observable universe is getting smaller, which makes no sense since the universe is expanding. :oldconfused:

According to the Big rip theory if Black holes tear apart after a very long time, then according to the theory of relativity an object that reaches the event horizon should see time passing infinitelty and by the time the object was swallowed wouldn't the black hole not exist anymore because of...

If space time (the universe) is infinitely expanding what happens when it rips? Have we observed Virtual particles in an area and counted them? Does the expansion of space time affect the amount of Virtual particles in a particular area? Is it theoretically possible to expand space time to a...

The oldest human-edited directory of web sites, http://www.dmoz.org, is closing on March 14.

If so, what causes it to rip? Does it "heal"? What would a rip look like to us? What is the tension threshold at which spacetime rips? What are the units of this "tension"?

In the big rip theory, the force of dark energy isn't constant and increases over time. This causes first galaxies to fly apart, then solar systems, then planets, then stars, then atoms, then the atom nuclei. If it keeps increasing, it would start pulling the quarks inside protons and neutrons...
