About Light Speed Travel

Post #1by Alextang » 15.06.2018, 07:35

Hi all! I am new to this forum and so eager to discover Celestia. I have one query following:

The light takes aproximately 8 mins to reach earth from the sun. However how much time does the light experience while making the trip? Meaning if someone traveled for 8 mins at the speed of light how much time would he count on his watch? The 8 mins are counted by someone outside the "vehicle".

And if we travel faster than light what decides how long the trip should last? Like would it be instant or negative time and how much of it?

Thanks in advance!
