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 ...
When stars explode as supernovas, they produce shock waves in the plasma surrounding them. So powerful are these shock waves, they can act as particle accelerators that blast streams of particles, called cosmic rays, out ...
