Light speed is the speed limit of the universe. So if something is travelling close to the speed of light, and you give it a push, it can’t go very much faster. But you’ve given it extra energy, and that energy has to go somewhere.
Where it goes is mass. According to relativity, mass and energy are equivalent. So the more energy you put in, the greater the mass becomes. This is negligible at human speeds – Usain Bolt is not noticeably heavier when running than when still – but once you reach an appreciable fraction of the speed of light, your mass starts to increase rapidly.
Ah, many thanks for explaining.
ReplyDeleteso let's say you are on a ice that is about to break, what do you do, Run or slowly walk?
ReplyDeleteDoesn't make a difference as it's almost undetectable in the weight. If you encounter ice, I would advise that you don't tread on it.
DeleteLay down distribute you weight
DeleteThen why light isn't heavily massed

DeleteBecause photons don't have mass (the photons are the light particles, simply saying)

(also, an English College Physician? A physician is a doctor... You meant physiciat. Though I highly doubt you're that either)
Objects do not “get heavier,” they simply gain mass. You have to insert a gravitational field to weigh an object and conclude it has gained weight.
