the speed of light

Chinese scientists claim to have found important evidence for the hypothesis that gravity moves at the speed of light, based on data collected from the tide.

Science developed, achieved unexpected achievements, but until now, scientists still succumb to many mysterious phenomena.

The Milky Way, the galaxy that holds us and the Solar System, is a large place. It is so big that we may never get out of it. So if there is a chance, how long will we go?

An American scientist claimed to have found evidence that the speed of light described by Einstein's general theory of relativity was slower than the long-held assumption.

Light moves at a speed of nearly 300,000 km / sec (about 1 billion km per hour). It only takes more than a second to reach the moon and about 8 minutes to reach the Sun.

Russian scientists released the device into Lake Baikal in hopes of shedding light on the nature of dark matter and the origin of the universe.
