Light is the fastest-moving thing in the universe. So what would happen if the speed of light were much, much slower? In a vacuum, the speed of light is about 186,000 miles per second (300,000 ...

While quantum physics continues to raise new questions(Opens in a new window) concerning Einstein's theory of general relativity(Opens in a new window), a recent ...

THERE are some close Earth satellites carrying radio frequency transmitters. By means of the Doppler effect, the radiation from the transmitters received at ground stations is used to infer the ...

To make the admittedly weird concept of relativity easier to understand, a team of developers has created a video game that slows down the speed of light. Relativity is the theory that space and time ...

I am so intimidated right now...I think I understand less about relativity now than before I asked the question. I think - if I understand things as written - that time can be observed to slow for an ...

A Hiroshima University team has designed a feasible way to detect the Unruh effect, where acceleration turns quantum vacuum ...

The findings resolve a long-standing problem in fundamental physics. Scientists at Hiroshima University have created a ...

Wave scattering appears practically everywhere in everyday life--from conversations across rooms, to ocean waves breaking on a shore, from colorful sunsets, to radar waves reflecting from aircraft.
