### Do Closed Timelike Curves Exist or Not?

A number of solutions to the field equations have shown that closed timelike curves can exist. However, there’s still uncertainty regarding the existence of closed timelike curves. Why is this the case? […]

Kurt Godel exposed some logical inconsistencies with the general theory of relativity, but Einstein was skeptical and didn’t believe it had any real world implications. Why is that so? […]

Kurt Gödel thought he had found certain logical inconsistencies with the concept of time, as we know it. So, what was time like in Godel’s cosmological solution and what was the nature of Godel’s universe? […]

There was a gradual development and redefining of physics and reality due to certain new discoveries. What were the old influences that led to this change? […]

Particle accelerators provided a way of isolating subatomic particles and observing them. How did this help physicists develop the standard model, as well as validate the quantum field theory? […]

What were the studies and developments in quantum mechanics that changed how we viewed matter from a deterministic perception to a probabilistic one? […]

Einstein wasn’t alone in the search of a Unified Field Theory. From Weyel’s version of metric tensors to Kaluza’s Fifth Dimension to Eddington’s Affine connection, there were many attempting to build a Unified Theory. […]

For a period of three decades, Einstein searched—with very little success—for a unified field theory. What comprises a unified theory, and what is its significance? […]

Einstein’s failure in achieving a Unified Field Theory didn’t stop the others. Grand Unified Theories and String theory continue to search for a viable Unified Theory. […]

The many-worlds interpretation proposed by Hugh Everett hasn’t replaced the Copenhagen interpretation, but the two co-exist. Why is that so? […]
