Speed of light: Fastest speed in the universe or not?

For Woeler1 and Regulus.

But.. they said that they found something faster than the speed of light so.. I guess I believe it.
Seriously who knows
Maybe we will ever be able to travel back in time!! O:
Woulnd't that be SO AWESOME?! 8DD
It sounds impossible to me, but... xD

Just pasting my post from the "other" thread (apologies again, I thought this was the duplicate one >.>)

I thought this was all but a fact?
Is there really much room to debate something that makes sense? Yeah in case not obvious, I believe it is the fastest speed possible yes.
The speed of light, if I am not mistaken requires an infinite amount of energy to reach. With that in mind, no amount of energy can make anything in the known universe pass c (speed of light).

Yes but what they did not tell you is that the machine which tested it has a slight delay in it's results and they did not close the tunnels which run below the machine, which could have created false results.

the media only posts what they wanna post. they don't post what it actually was.

COULD have created false results.
So that doesn't mean it's not true. ^^

But, it is important to remember that everything in space is relative.

Perhaps I'm just being a moron here, but I don't understand how there can be a constant speed of light. Allow me to explain. We are revolving around the sun at a speed of about 67,000 miles per hour. Keep in mind that the sun itself is also moving, spinning around the galaxy. And, as we all know, galaxies aren't stationary either. If we're moving away from the center of the universe at a speed of 0.6c, and so is another galaxy on the other side of the universe, then our relative speeds exceed the speed of light, at 1.2.

But, seriously, think about this. If particles in the hadron collider are traveling very close to the speed of light, then they must be going faster than the speed of light relative to the sun, for example. But, surely, that can't be possible, as the speed of light is supposedly a constant in every frame of reference.

I've talked to many people about this, and I haven't received any sort of explanations.

While the theory of relativity does make sense, and was no doubt a great scientific advancement, I don't believe we should follow Einstein's work like it is perfect.

[Regulus]

In Einstein's theory all speeds are measured compared to an object at rest.

Exactly, but there is no such thing as rest, because everything is moving. If you're in your car, driving down the road at 20m/s, and you turn on your lights, the photons still only move at a speed of c, relative to the ground.

But then, relative to the car, the light is moving at a speed of c - 20m/s. Einstein specifically stated that the speed of light never changes. Likewise, the rear lights would be moving at a speed of c + 20m/s relative to the driver.

It still makes no sense to me.

[Regulus]

You're right, I forgot about time dilatation.

So, basically, the speed of light is a constant, and time is not. That makes sense now.

Believe it or not guys, Scientists have apperently found something faster than the speed of light.

Particals were shot through the earth to another loation for some scientific test, but there was an imput error in the computer. Scientists found that because of this error, the Particals had moved much faster than the speed of light going through the Earth to the other location. Last I heard it look less than one milisecond to reach the second location, like a fraction of a milisecond or some crazy small number. Apperently, they tried it multiple times and got the same result. I don't know the whole story, I don't know how much of this is true, and I lost the article on this, but if u guys find it by all means post it here. This is all simply what I remeber from the article. Pretty interesting stuff.

Please do remember that a nanosecond is quite a lot less than a millisecond.

Yes this news came from the LHC and they shot particles named neutrinos. However the machine has a measurement delay and they left the tunnels that run below the machine open all the time.

What the media tells you: neutrinos move faster than light, einstein was wrong!

What actually happened: there might be one neutrino that could have been moving at a speed faster than light but it's within the machines delay and the tunnels were left open. So probably not.

The delay / margin of error is apparently 10 nanoseconds, the neutrino beams despite this still reached the destination 60 nanoseconds faster than c. At least that is what the reports are saying...

Article I read definitely had the numbers the other way around, but I will take your word for it, Doh! =P
