We may have already found evidence of an evolving, dynamic kind of dark energy from the first stars in our universe. When you purchase through links on our site, we may earn an affiliate commission.

One of the greatest unsolved puzzles in all of science is dark energy. The Universe isn't just expanding, but the expansion rate that we infer for distant galaxies is accelerating: their recession ...

There may be an exotic form of dark energy lurking in the universe, and it could explain a stubborn discrepancy in measurements of the universe's expansion rate. This so-called early dark energy might ...

In A Nutshell When two different types of cosmic strings become linked in the early universe, they form stable knots that ...

Dark energy is the name physicists have given to the mysterious thing driving the universe's accelerated expansion. It may be a force or a form of energy, and one piece of evidence suggests it is ...

For more than a century, physics has been built on two great theories. Einstein's general relativity explains gravity as the bending of space and time. Quantum mechanics governs the world of particles ...

Let's rewind the clock back…oh, I don't know, let's say a hundred years. It was 1917, and Einstein had just developed his ...

Einstein’s gravity-explaining theory of general relativity may not tell the complete story of how galaxies and black holes formed throughout the universe. New supercomputer simulations implementing ...
