A pair of researchers at Surrey University has attempted to show what a bicycle moving at near the speed of light might look like to a human observer. In their paper published in the journal Proceedings of the Royal Society ...
Take a look at the moon and it isn't hard to imagine it as a planet. A 3,476 kilometres-in-diameter ball of rock, with basalt plains and mountain ranges, whose gravitational pull produces tides here on Earth.

(Phys.org) —A pair of physicists has proposed a thought experiment to help reconcile the seeming disparity between the psychological and thermodynamic arrows of time. In their paper published in the journal Physical Review ...
We thought we understood how big rocky planets can get. But most of our understanding of planetary formation and solar system development has come from direct observation of our own solar system. We simply couldn't see any ...

A group of physicists at the University of Basel, in Switzerland, has found via experimentation that the Einstein-Podolsky-Rosen paradox still holds even when scaled up. Paolo Colciaghi, Yifan Li, Philipp Treutlein and Tilman ...
In our everyday classical world, what you see is what you get. A ball is just a ball, and when lobbed through the air, its trajectory is straightforward and clear. But if that ball were shrunk to the size of an atom or smaller, ...
