Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. There are two fundamental classes of theories required to describe the ...

The hyperdrive from Star Wars appears to depict an ultra-relativistic motion through space, extremely close to the speed of light. Under the laws of relativity, you neither reach nor exceed the speed ...

In my recent post about calculating the speed of light, I mentioned Ole Roemer's calculation in 1676. The basic idea uses the orbit of one of Jupiter's moons. The orbital period is constant, but there ...

In 1676, by studying the motion of Jupiter's moon Io, Danish astronomer Ole Rømer calculated that light travels at a finite speed. Two years later, building on data gathered by Rømer, Dutch ...

In the realm of physics, the speed of light is considered one of the most fundamental constants in the universe, dictating the structure of time and space as we know it. But what if this cornerstone ...
