A straightforward math tweak could bring tachyon fields into line with the rest of physics. Tachyons are faster-than-light particles, and tachyon fields are special cases of quantum field. The math ...

In the past quarter century, astronomical observations have led to discoveries that have literally transformed our conception of the universe. One such transformation occurred in 1998, when dark ...

Now it seems that wormholes, those shortcut tunnels through time and space that Albert Einstein theorized and that science fiction depicts as portals between two distant galactic points, are at the ...

When does a concept become concrete? How does an abstract idea evolve into something we believe — maybe even know — is a part of our universe? How does the lens of time transform an artifact of an ...

Recent advancements in observational techniques have led to the capture of high-resolution images of black hole shadows, which are challenging the completeness of Einstein’s general theory of ...

It took Albert Einstein 10 years to find the equations of general relativity, but German astrophysicist Karl Schwarzschild only needed a few months to solve them. Schwarzschild’s solution describes ...
