Okay guys, This isn't meant to be a riddle or anything, just me trying to get a better understanding of time.
So, according to Einstein's theory of special relativity, we live in a 4-dimensional world. With the dimensions of X,Y,Z and time.
Time being a fixed dimension that is measured with the speed of light.
So here's the question:
Suppose Grandpa Max decides to do something crazy on his 50th birthday (August 15, 2020). He gets on a cool little spacecraft and flies it at the speed of light (3.0 x 10^8 m/s).
Now, Grandpa max has a watch/calender on-board his little spacecraft and decides he'll return on his 51st birthday, to a big celebration.
To a person on the ground, When will Grandpa Max return to earth? Will Grandpa Max have aged at all?
