About one-seventh of a second. But it would SEEM like it took no time at all.
Yes, but only if you could run at the speed of light
Light does not go around the world. It travels in a straight line. For light to go around the world, it would have to periodically redirected using mirrors.
No - you would be stopped BEFORE you reach the speed of light, by your increasing mass (among other things). As your speed approaches the speed of light, your mass would approach infinity, and it would require an infinite energy to actually achieve the speed of light.Note that the "speed of light" is not really about light. It is a speed limit of our Universe; some have described it as the "speed of causality".
If you were travelling faster than the speed of light then yes, but if you were not travelling at light speed you would not. Travelling at light speed can take you around the world 7 times a second.
Nothing in particular, unless by "speeding" you mean "at relativistic velocities" (close to the speed of light). That would have an impact on your perception of the world around you.
speed of light = 299792458 m/s time it takes light to travel around the world = 40075160/299792458 = 0.134 seconds time it takes light to travel around the world 7+1/2 times = 1.005 seconds
The oppositeÊof E=mC2 would be m or mass equals energy divided by the speed of light squared.Ê The C in E=mC2Êin real world terms would be the speed of light.
Light can travel once around the earth in .00013358 seconds.
it would take about 1 hour.
No such thing would happen. Matter cannot reach the speed of light, only massless things can (and they cannot travel at any other speed than the speed of light).
Light years
To travel at the speed of light you would have to BE light so i guess you would became an even brighter light The switch to turn on the lights will work but no light will come on as you are already at that speed
