Previous models explored the illusion, but this is the first time it has been actually recreated in a lab setting.
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 ...
For the first time, physicists have simulated what objects moving near the speed of light would look like — an optical ...
Speed is a measure of how fast an object is moving. Calculate speed using the speed equation - speed = distance divided by time. The speed equation can be rearranged to find distance travelled and ...
Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. One of the fundamental rules we all learn in physics — set forth by ...
I love using seemingly random data to figure out stuff I wouldn't otherwise know. You can do this with all kinds of things, but in this example, I use video that I recorded from an airplane to figure ...
Chris Impey receives funding from the National Science Foundation and the Hearst Foundation. Curious Kids is a series for children of all ages. If you have a question you’d like an expert to answer, ...
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 ...
