None. No astronaut or man-made object has ever gotten close to the speed of light. It is impossible for an object to actually travel at the speed of light.
Sails that are pushed by light is one concept.
They did not, so the question is misguided.
The technology to travel at or near the speed of light does not exist and is nowhere close to being developed. No astronaut or man-made object has travelled to other stars.
Engines cannot travel at light speed. The only thing that can travel at this speed is the Photon, the particle of light.
this thing dose not give u the answer!!!!!! does is spelled D-O-E-S smart 1
Nobody has ever traveled at the speed of light, and I can promise you that nobody ever will.
They did NOT use 'light speed' ; Speed of Light'. Mankind has never created an object that will travel any where near the Speed of Light. The Rocket blast off . It reaches a speed that will allow the spaceship to escape the Earth's gravity. After that it 'sling shot's' around other astronomic objects using their gravity.
Roemer was the first to measure the speed of light.
First of all, you would have to be dead to go to heaven or hell. So basically, the answers is no.
it would take apporximately 4.2 seconds, jduging the wind speed in space, if light speed technology did exist.
No real limit, up to the speed of light. The Apollo astronauts traveled at ABOUT 32 times the speed of sound on their trip to the moon. That is the fastest yet.
The speed of light is faster than the speed of sound
