The speed of light has been broken ! "allegedly"

the faster something travels more its mass will increase, the higher the mass the more energy/power required to move it.

any normal object reaches the speed of light its mass will be infinite so to move it forwards you would need infinte energy/power, which is impossible so = nothing with mass can travel faster then light.

Introducing the notion of a relativistic mass that changes depending on the velocity of the object is a bad one, and isn't used any more in text books etc.

now things like light, electricity have no mass to begin with therefore no matter how fast it travels its mass cannot increase as it never had any to begin with. light isn't the limit exactly, but because its isn't affected by the increase of mass it can travel theoretically as fast as it wants.

Electric current is the movement of electrons, these have mass and therefore can't travel at the speed of light. :o

Just to point out though, whilst photons do not have a rest mass, they do have momentum (p = hν, where ν [nu] is the frequency of the photon)

so soon as you hit the speed of light theoretically you should either be frozen forever or dies with the universe if it ever ended, but if you travelled a bit slower then light to an outsider it would seem like you moving but very very slowly. This time you would reach your destination v quickly depending on how fast you are travling (not at the speed of light thought) it would seem mear seconds from your point of view or even instant, but when you get there a great deal of time would have passed centuries/eons/ect/ect,

Time always appears to pass normally to you (you personal time) but to another observer their measurement will be different. I think you have it the wrong way around in your example though; if I travel very very quickly, time appears to pass normally to me but to an observer in another inertial frame of reference many years might have passed.
 
All your thoughts and words are based on the fact that you believe two things.

1) E=MC2

and

2) light and time know about each other...

what happens if E=MC2 is not quiet right and what happens if light speed, the messure we humans have given it is all wrong...

I for one can not belive that we cant break any speed barrier, we have broken every one before and will do again in some way. It what we as humans do, push the envelope to the max line, then step over it.

just a thought.

hahaha!

i think the problem with this kind of physics is no on actually has a clue what they are talking about. they just make stuff up and then create new rules for the stuff they made up.
 
I dont think that if you travelled faster than light you would arrive before you left... you would arrive in a time scale equal to how long it took you to get there, which can never be a negative amount of time because even at 300,000 miles per second you still take a second to make that distance, or 1/300,000 of a second for 1 mile, etc.

It would however be faster than we could see, since our eyes only see so many "frames per second". But so what?

This whole speed-of-light business doesnt mean a thing imo.

But of course, I'm no physicist, so cant think in terms restricted by "theories" and other clever things.
 
I haven't read the thread replies yet but this quote is impossible, isn't it?
The pair say they have conducted an experiment in which microwave photons - energetic packets of light - travelled "instantaneously" between a pair of prisms that had been moved up to 3ft apart.

Maybe they perceived it to be instantaneous because light travels really fast?

Isn't instantaneous a mathematically impossible statement?
 
i dont think a 3 foot gap is sufficiant to scale the measurement of time taken.
3 miles i would be a little more impressed. 300 and we might have a fighting chance of making a judgement.

3 foot. ludircous. an excellent study, but a bold statement to make.

Only if time is a definite linear motion rather than an assumed observable truth. That's the thing about the scientific method, there's a lot of assumptions, many of them necessary for the method to function.

The thing with discoveries such as this, if it proves to be replicatable and accurate, is that, like the discovery you can split an electron, they don't make any difference to the validity of the theories as the theories remain predcitively accurate. As such, they will remain a curiosity until someone comes up with a new theory that's predictively accurate and takes the new discoveries into account in their assumptions.
 
Don't get too excited... this isn't "BREAKING" the speed of light - Einstein's theory still holds true. Quantum tunnelling is a "loop hole" similar to wormhole theory that allows objects to arrive at a point faster than if they had moved there obeying normal rules such as the speed of light limit.

We have already seen instances of this phenomenon for a long time - Quantum entanglement for example. "Information" is shared between 2 entangled particles instantaneously over any distance that they are seperated. The "information" is not travelling between the particles by normal means otherwise it would be bound by the speed of light limit.

Lightspeed is still a fixed speed because as mentioned you would have an infinite mass if you were travelling at the speed of light. So it is impossible. This is a way around the barrier though, it does not break it!

Define normal! Just because it doesnt use a rocket as propulsion doesnt make it a less valid transmission. And if it moves faster than the speed of light, regardless of the method it is still faster.

I'm afraid you're going for a cop-out answer here. Simply declaring "it must be doing something else" so it doesn't damage an existing theory isn't good scientific practice...

Quantum entanglement and quantum tunnelling point to there being more to predicting the universe than the models we currently have, however they do not stop the existing models from being predictively accurate.
 
wait so hes made light... move faster than light...

so doesnt that just mean we have even more work to do to go faster than light :S
