Speed of light

poisson · 14th August 2008, 16:30

I have a question.

Can an object reach the speed of light??

I've heard that in some experiments, as an object was approaching about 95% the speed of light, its mass started to increase, so as a result it slowed down!

How the fuck do you explain that??

so its impossible to reach the speed of light?

esmufc07 · 14th August 2008, 16:32

Perhaps.

poisson · 14th August 2008, 16:33

how insightfull.

esmufc07 · 14th August 2008, 16:33

Maybe

poisson · 14th August 2008, 16:34

speed of light = 300 million m/s or 186,000 miles per second.

esmufc07 · 14th August 2008, 16:35

Or 11,160,000 miler per minute.

i have it on good authority that frank lampard can travel at three times the speed of light to a free buffet.

poisson · 14th August 2008, 16:36

is light made up of particles? Or is it a wave??

there is evidence that proves both!!! Crazy stuff!

This should answer your question

m0
m = ----------------
sqrt(1-v2/c2)

Pilgor's Revenge can reach the speed of light and it's only held up by a battalion of turtles, pulled by three sharks, and propelled forward by some desktop fans.

poisson · 14th August 2008, 16:39

What is wrong with you people?????

I can explain that.

This object was going so fast, nearly the speed of light, once that happened, it's mass started to increase, obviously what resulted then was a slow down.

Easy really.

Nothing can reach the speed of light because they are not supposed to. The world will explode if it happens.

Heard that some stuff sucked by black holes approach speed of light.

Theory of relativity describes why the mass of object increases at high speeds. Its quite complicated to understand, and i still haven't got grips of the concept after fair bit of reading in past.

but WHY did its mass increase? thats what i want to know!!!

You bet your ass it can.

interesting.

I've heard that light can't escape backholes, its pull of gravity is so strong!

mo is the original mass and m is the mass at velocity V. So, as the velocity tends to C(mass of light), the mass tends to infinity.

From wiki-

The Universe is expanding, and the far parts of it are moving away from us faster than thespeed of light. This does not contradict the theory of special relativity, since it is space itself that is expanding.

Because it nearly reached the speed of light.

That's what happens every single time, haven't you done this before?

We did it at school a while back, my best mate exploded. RIP.

Its all paper talk assuming a lot. Nobody actually knows whats happening.

This question addresses Einstein's theory of Special Relativity.
If my answer does not satisfy you, there are many clear books on
the topic in any university bookstore.

When a particle/object travels close to the speed of light, and is
thus considered "relativistic", the energy of the particle is
expressed as E = (gamma)*mass*velocity. Here gamma is a relativistic
factor that is greater than unity. So, one could consider the
factor (gamma)*mass a new mass, one that is larger than the mass
of the particle when it is at rest. This is why you hear that
mass increases when you approach the speed of light.

It can be argued that it is only an appearance of greater mass, or that it
depends on how you look at the problem. In short, it is all relative.

It should be noted, however, that in order for an object to actually
reach the speed of light, it must have no mass, since E=mass*speed of
light^2. This is true of massless particles such as the photon,
the "particle" that transports light.

* =multiply by
^2= squared

But then again who the fuck cares...

good stuff.
That makes it clear why a mass will never reach the speed of light, because it would require an infinite force.

But how does its mass increase as you approach the speed of light?
Where is this extra mass coming from??

I guess you are right. No firm evidence on any of this stuff yet.
