“Using newer mathematical tools, my colleague and I have demonstrated a new theory that may accurately describe the universe. Instead of basing the theory on the warping of space and time, we ...

Few ideas in modern science have reshaped our understanding of reality more profoundly than space-time—the interwoven fabric ...

Key Takeaways on What Space-Time Is Einstein's theory of general relativity views time similarly to width, height, and length. As such, both time and space can be curved by gravity.

Reference: Einstein's Theory of General Relativity Philosopher David Hume's 1738 "A Treatise of Human Nature" was a big influence on Einstein's thinking about space and time.

Einstein's theory on its own is just fine, describing how matter-and-energy relate to the curvature of space-and-time.

Once space and time themselves are flexible rather than fixed, what else is left that we can say is truly constant? There is one obvious candidate, again from Einstein himself: the speed of light.

Quantum mechanics is perhaps the most unintuitive theory ever devised. And yet it’s also the most successful, in terms of sheer predictive power. Simply by following the math of quantum ...

The theory combines the ideas of particles and waves into a concentration of energy that flows throughout space and time. The researchers used the theory to answer two problems solved by Einstein.
