What happens if you go faster than lightspeed?
What happens if you go faster than lightspeed? Einstein and Hawking are both right, but you don't travel faster than light. You can reach your destination as soon as you like (almost), but you leave the rest of us behind for ever (almost).. If you could reach the speed of light, time would stop for you and you would be there in an instant.
Do wormholes exist?
While researchers have never found a wormhole in our universe, scientists often see wormholes described in the solutions to important physics equations. Most prominently, the solutions to the equations behind Einstein's theory of space-time and general relativity include wormholes.
What happens if you turn on a flashlight at the speed of light?
At any rate, the beam of light emitted by your flashlight would appear to reach the far wall instantly, as the speed of light is independent of your speed and would always be constant at about 300,000 kilometres per second in a vacuum.
What is the speed of dark?
Most of us already know that darkness is the absence of light, and that light travelsat the fastest speed possible for a physical object. So, what does this mean? In short, it means that, the moment that light leaves, darkness returns. In this respect,darkness has the same speed as light.
