Okay .. As we all know, objects with a mass gain weight when traveling fast. We all know that it would be close to impossible for us to travel with the speed of light since objects would gain so much more mass + weight in such speeds..

But ny 1 know the mathmaticss behind this ? Coz I was wondering if something sucked into a black hole wouldnt gain incredible mass and weight since it would travel so much faster than light it self ?????

And if so, wouldnt it be impossible for a black whole to ever swallow a planet/star ?? O_o

inb4 dynamic mass approaches infinity at speed of light

heres my 2 cent.

black holes have the gravitational power to pull light into them. that doesnt mean the way a black hole works is through a faster than light method. simply means a black hole has massive amounts of some sort of power.

Something like this, I can't find the equation that would yield the mass of one object in relation to another but I would assume that with what we see, the force affecting such a mass would increase drastically as the mass increased and its distance between the two masses decreased.

Too me, you can be near a black hole, and NOTHING will happen. Its when you get too close, and enter the event horizon when shit starts to happen. For example, one leg outside the horizon, nothing happens. Put the other one inside the horizon and your leg will stretch, rather then break off. I would think that it wouldn't happen at such incredible speeds. It would be fast, but not so fast as to say it gains INCREDIBLE mass.


I don't know. Just doing what i do best. Ranting.

nobody here actually knows shit

enlighten us great 09 spammer.

ok ive read this though a few times and ive never heard of somthing gaining weight while travaling fast
weight is determined by a constant force in one direction right?
so wouldnt the black holes gravitational force just be temp force? making it only heavier in that direction

you don't think "nobody" included me?

then you've only ever heard of rest mass. which is good for you, kind of, since all of this relativistic mass shit is boring.

For OP, the mass gained by an object at great speeds is given by the relativistic mass, m=mo/sqrt[ 1 – (v/c)² ]. If v=c, the relaivistic mass approaches infinity. Hence the shit about not travelling faster than the speed of light. I'm not sure about the shit about objects travelling faster than the speed of light in a black hole. I'm pretty sure shit with 0 rest mass is the only thing that can travel the speed of light (and it must).



No, weight is determined by an acceleration. Weight is a force. Although acceleration is caused by a force also, but either way I'm not sure wat your point is.



What does that have to do with the speed of light question?
