For decades now, many physicists have pursued the hope that equations involving an especially tiny "string" could provide the ...

A new model based on the famous alien-hunting Drake equation suggests that some parallel universes within the hypothetical ...

An curved arrow pointing right. CalTech theoretical physicist Sean Carroll stopped by BI to talk about string theory, parallel universes, and other exciting topics he discusses in his new book ...

Out of the limelight, theoretical physicists continue to seek a mathematical model that can explain the universe's particles and forces.

That would be compelling evidence for both string theory and parallel universes, and it would help explain why gravity seems to be so much weaker than the other fundamental forces. Still ...

In order for that to work, string theory has to make one more radical assumption. That instead of living in a universe with three dimensions of space and one of time, we live in one with either 9 ...

It also points a way forward for astronomers to find evidence of the existence of parallel universes ... esoteric branch of physics called string theory. These techniques enable researchers ...

according to string theory, exist in parallel dimensional membranes—bump into one another, the impact sets off an astronomical Big Bang that generates a universe-worth of elements in the fiery ...
