My head is now full of fuck...
Hopefully they come up with an explanation for this!

All you have to do is witness one object moving at .6 times the speed of light towards you, who may also be moving at .6 times the speed of light.
Then you would go "OMG 1.2 SPEED OF LIGHT WE DID IT GUYS" and you would even be somewhat correct. Uh.... no. You need to read up a little more on relativity. The reason the speed of light is so important in physics is because it is an ABSOLUTE constant, regardless of the relative perspectives. Speed of light is taken from point of origin. As far as we know, there is no absolute point of origin in Space. Time dilation is also relevant. Also speed of light is the same as speed of information. If I move a magnet one light year away from another magnet, it would take one light year for the other magnet to respond.
Do your reading good sir. It would be a shame if you were to embarrass yourself.
+ Show Spoiler +Basically what you are saying is that the light coming from the headlights of a moving car is going faster than one that is not moving. NOT TRUE.

Apparently, this isn't the first time people have claimed neutrinos are tachyons. http://blog.vixra.org/2011/09/19/can-neutrinos-be-superluminal/ Cool article on the topic. Basically, evidence indicates that some kinds of neutrinos might have imaginary mass (mass-squared calculations have shown results that might be less than zero).

While this is.. interesting? I guess? Einstein's theory says nothing can pass you faster than the speed of light ('c'), however we already know that galaxies are moving away from us faster than 'c', or at least they appear to be.
Relativity what a bitch you can be.

According to modern physics the speed of light holds constant for ALL perspectives.

That's actually not completely what I am saying, really close though, although I should have been more accurate for certain.

The distance between the Milky Way and some other galaxies are increasing faster than the speed of light, not that the galaxies themselves are traveling faster than the speed of light.

Yeah, I should probably restate what I was saying. Light is extremely unique, I was not referring to light itself, I was referring to non-light objects. You are correct though.

If the Sun disappeared instantaneously, it would take ~8 minutes until we see it vanish, of course due to the speed of light.
So if information cannot travel faster than the speed of light, would the Earth continue in circular motion about the Sun for 8 minutes, or fly away at a tangent immediately?
Just a cool idea while we're on the subject :D
Gravity wouldn't "run out" for about 8 minutes.

No. Until now, nothing with mass has been observed to move faster than c, in any frame of reference. So many people that don't understand relativity in this thread.

The funny thing is that this result will probably be scrutinized to a point where there is either found an error in it or these occurances and especially the geology the neutrinoes has passed will be studied and mapped and documented for many years to come.

We have observed this phenomina, however we lack an understanding of why it appears this way. A common explanation that was told to me is that the galaxies are not moving away a rate greater than c, but that more space between us and them is being created which leads to the perception that c is being breached.

Maybe i misunderstood your thought, so explain me what do you think about this: If you see 2 trains moving 1 against each other at something like 0.9c (c= light speed)m what is the speed of 1 train, seen by the other one?

Well, that's true, but it works at a cosmological magnitude, not for little distances. Also, you can't in ANY way see something moving at speed faster that c away from you, for the phenomenon of relativistic redshift the light emitted by them would reach you with a insensity near to zero.

After a certain distance yes, and no... The thing is space itself is expanding in all directions. Every second you and I are slightly farther away, although gravity the gravity of the earth. Over long distances the expansion requires you to go faster than the speed of light to reach that object. I'm not sure if this qualifies as going faster than the speed of light because the object itself is stationary but space itself is being warped around it.

The expansion of the universe would only violate relativity if it were to exceed 2c along the diameter of an expanding sphere. Assuming you consider the universe as a sphere, rather than say a toroid or a more complicated geometrical shape.
It is absolute magnitude of velocity that is considered for the purposes of relativity, not apparent. Apparent magnitude can exceed c, absolute can't.
The neutrino has absolute magnitude exceeding c. We know this because the source is in the same reference frame as the experiment detecting them.
Over long distances the expansion is requires you to go faster than the speed of light to approach. I'm not sure if this qualifies as going faster than the speed of light because the object is stationary but space itself is being warped.
If you consider the velocity of a galaxy to be around +0.6c, you need a shift to -0.6c or more in order to catch up with the galaxy on the opposite side of our hypothetical spherical universe. While the total velocity itself with respect to the original reference frame might appear to be 1.2c, you are actually travelling at 0.6c with respect to the reference frame of the origin of the model at both times, and >0c with respect to the reference frame of the galaxy you are attempting to reach.
This subtlety is why when a car collides with your house, it hits with the force of 30mph, now 65,030mph.

Thank you for this post! My understanding is below-laymen, so anything like this helps. I try to read up on my own but uh... Physics is hard yo ;P
Thanks again for the clarification

I believe due to time dilation that the "experience" is that it will come at you at .999999c however the measurable time difference is such that 1.8c can be observed from a historical standpoint (after the fact)

Well seeing as physics is thousands of years old then i would say 1915 would be fairly modern
