Like stretch marks left on skin that expanded too quickly or cracks embedded in freezing ice, cosmic strings are artifacts of ...

We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole ...

Planets orbiting dead stars known as white dwarfs might be able to remain habitable thanks to general relativity subtly altering their motion. When stars like our sun run out of fuel, they expand and ...

Wormholes are often imagined as tunnels through space or time—shortcuts across the universe. But this image rests on a ...

Independent researcher and CEO of IDrive Inc., Raghu Kulkarni, has unveiled a groundbreaking framework for understanding the universe: the Selection-Stitch Model (SSM). The model suggests that ...

Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time and the latter a point in space, but in both cases the normally ...

Astronomers have finally watched a black hole do something Albert Einstein only described on paper: twist the very fabric of spacetime around it. The new observations capture a spinning monster ...

China has quietly solved a problem that only becomes obvious once you try to live and work off-world: clocks on the moon do ...

To progress to the next level in understanding reality, we need to combine quantum mechanics and Einstein’s general ...

110 years ago today, Albert Einstein published his General Theory of Relativity, which redefined the relationship between matter and gravity. Suddenly, our mysterious universe made a little more sense ...
