Alien ‘warp drives’ could leave telltale signals in the fabric of space-time, a new paper claims

“Warp drives” used by super advanced extraterrestrial civilizations can create specific space-time ripples in their wake that we can see from Earth, a new paper claims. The jury is still out on whether the faster-than-light technology is even possible to create.

A warp drive is a hypothetical device that allows an object to travel faster than lightIn theory, the device creates an invisible sphere around an object, called a warp bubble, which space time in front of it while the space-time behind it is expanded. This effectively moves the universe around the object, allowing it to get from point A to point B faster than the speed of light.
