Reply to comment by flowersonthewall72 in Did you know it will still take 46 billion years to cross the universe at the speed of light? 65 mph = 4.8 * 10^17 years! by NotAndroid545

Light takes 8 minutes to get to earth for an outside observer. For the object moving at light speed, a photon in that case, it's instantaneous. This is basic relativity.

Light takes 8 minutes from the sun to earth. That implies if you were to travel the speed of light, it would take 8 relative earth minutes for you to make it the distance of the sun is from earth.

But your perspective of time would be almost instantaneously.

Not almost instantaneous. It would be actually instantaneous. It would take you 0 seconds to go from the sun to the earth, or from the sun to Andromeda.
