autograv is a Python library that uses JAX and automatic differentiation to compute various tensors and quantities from Einstein's general theory of relativity. Given a metric function, it can ...

ABSTRACT: In the present paper, a connection between gravity, space and quantum mechanics is discussed. In particular, the problem of directly quantizing space is by-passed by the suggestion, starting ...

A Python-based web service for tensor operations and differential geometry calculations, supporting both symbolic (using SymPy) and numeric (using NumPy) computations. The backend is built with Django ...

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in ...

A new theory suggests that gravity could possibly be the result of entropy. If true, this would mean that everything in the universe would fall apart if it all remained unchanged. This theory tries to ...

Here’s what you’ll learn in this story: Time might actually have 3 dimensions. But it also means that the space would actually be one-dimensional, instead of the three dimensions we’re familiar with.

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still daring to test it. Some theories of quantum gravity suggest light might ...
