The breakthrough could suggest a way to study 'quantum gravity,' the missing link between quantum physics and Einstein's general relativity in the lab. When you purchase through links on our site, we ...

Time moves faster on Mars than on Earth. Physicists have confirmed this effect, crucial for future space missions. Even tiny differences in time matter for spacecraft navigation and communication.

Special relativity is beyond weird. Among its many statements are that moving clocks run slow and that moving rulers shrink. But how are we supposed to make sense of this? When you purchase through ...

In Newtonian physics, space and time had their independent identities, and nobody ever got them mixed up. It was with the theory of relativity, put together in the early 20th century, that talking ...

For more than a century, Einstein’s relativity has set a hard speed limit for the universe, with light as the ultimate traffic cop. Now a new generation of warp drive research, built from normal ...

It was already a mind-bending shift, last century, to go from Isaac Newton’s absolute space and universal time to Albert Einstein’s four-dimensional space-time, which is dynamic, flexible, sensitive ...

The theory of relativity describes two connected scientific theories developed by the physicist Albert Einstein: special relativity and general relativity. Collectively, relativity is the idea the ...
