String theory is a purported theory of everything that physicists hope will one day explain … everything. All the forces, all the particles, all the constants, all the things under a single ...

After 60 years, this beautiful theory hasn't produced many tangible results. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Paul M. Sutter is an ...

The idea that the universe is trapped on a membrane in some high-dimensional space–time may explain why gravity is so weak, and could be tested at high-energy particle accelerators. New directions – ...

The idea of String Theory is that our Universe came from a higher-dimensional, more symmetric, more complex state with an enormous number of degrees of freedom. In order for String Theory to be solved ...

Physicists have discovered a strange twist of space-time that can mimic black holes — until you get too close. Known as "topological solitons," these theoretical kinks in the fabric of space-time ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. String theory is perhaps the most controversial big idea in all of ...

Today's physicists are struggling with a quandary. They have accepted two separate theories that explain how the universe works: Albert Einstein's general theory of relativity, which describes the ...

Eight decades have passed since physicists realized that the theories of quantum mechanics and gravity don’t fit together, and the puzzle of how to combine the two remains unsolved. In the last few ...
