Proving Newton Wrong

If e = mc squared, as we approach the speed of light, mass is supposed to decrease.

Well, my weight is staying the same but I'm getting faster. Explain that.

    Einstein, not Newton.

    Mass, not weight.

    How do you measure your mass at top speed?

    As you approach the speed of light your relativistic mass (appears to) increases
    I like bikes...

    But if you lost weight and had a spill would you hit the floor sooner or later? :lol: At least you wouldn't feel the apple fall on your head because of your cycle helmet.

    No, the closer you get to the speed of light, the heavier your relatives get. Generally.
    There's always one more idiot than you bargained for.

    So as my wife gets heavier, the faster I speed away from her ?

    as long as she's using a Dyson. Well, I think it can be any vacuum.

    I though that was Specially, not Generally?

    There was a young time trailer named Dwight who could cycle much faster than light, he set out one day in a relative why - and returned on the previous night!

    ....and morefor those that are very very bored the formula for calculating relativistic mass increase is;

    New mass = old mass times 1/ the square root of (1- velocity squared / speed of light squared). So clearly as you approach light speed the bit in the last brackets becomes 1-1=0, and 1 divided by 0 is infinity!! All the carbon fibre in the world (or beyond) could not deal with that.
