Special Relativity - Time Dialation

670,616,629.2 to be exact, which is damn fast!

yes but its just as fast in Miles per second ;D ach well you were still 616,229.2 miles per hour out ;D

My bad .

Now why would they go and take all the fun out of shopping?

I'm buying mine at Alpha Centauri anyway

You rhetoric teachers and your cleverness....

I'll correct myself for the sake of clarity:

"But you can buy atomic clocks accurate enough to see the effect without having to put the clock in a satellite: you can in fact see the difference without having to leave the earth and take the clock to space."

See, NOW the paper will be the minimum 5 pages required. (and you didn't even have to increase the font size to 13)

So, the speed of light in a vacuum compared to in a medium.  You can't actually go faster than the speed of light though right?  You're only (theoretically) traveling faster than the photons which are being slowed down by matter?

Interesting... I'm kind of sceptical about it all though, there's not really enough info to say what actually happened...

There has been subsequent discussion of what is actually going on. Did the cesium "take" the information needed to produce the pulse and then transfer it "somehow" to the other side where it "released" the information to form the pulse again? This is possible with quantum states. The information was simply in more than one place and in more than one state at the same time. Did it pass through one of the other dimensions that are being theorized? If so, it may have "folded back" on itself so that the "exit" was in front of the "entrance." Is the limit on the speed of light simply wrong?

These types of questions take significantly longer than the length of a news article to be able to explore and most of the readers wouldn't grasp the concepts anyway. Before one can begin to understand an alternate view of cosmology, one must first understand how the human brain forces organization onto the information available and applies filters to what is available (philosophy/biology/psychology)

Mmmmm, spooky action at a distance.

Not exactly the same thing as what you linked though...or is it? ::looks off into the distance thoughtfully::

Maybe time to mention [ch268]erenkov radiation (also spelled Cerenkov or Cherenkov) is electromagnetic radiation emitted when a charged particle (such as a proton) passes through an insulator at a speed greater than the speed of light in that medium. The characteristic "blue glow" of nuclear reactors is due to [ch268]erenkov radiation. It is named after Russian scientist Pavel Alekseyevich [ch268]erenkov, the 1958 Nobel Prize winner who was the first to characterise it rigorously.[1]

Wow, that was some crazy shit! Totally awesome. Love the visualization, and I'm such a visual learner! I was always wondering, in theory, about the networking between humans across the world are effected by time and distance. What I mean, is that I believe that there is soft were designed for the xbox live, that is supposed to manage the time/distance ratio, which intern needs everybody's separate triple core xbox 360 processor along with the server's, to project the appropriate time to the appropriate player. There can be up to 16 players, but usually wtih vehicles and lots of action the system lags. Then, hackers even are able to code the system, lag everybody out, (freeze at their location) where they cannot move, then as soon as time comes back, they instantly die, because the fool reset the buffers and ran it wild, everybody stood their frozen, helpless because they had no tempo on the system! It actually takes allot of time to rob time by entering the code in gameplay, but ive seen this shit playing teams on line. He was able to pick each player, freeze their time, then kill them. Anybody who played halo 3 quite a bit knows exactly what I'm talking about. They are cheaters. Well I found that they usually like to come up and smack you over the head, so if you just sit there constantly attacking, I've even been able to kill them at the last second. Then of coarse, I "tea bag" the shit out of them.
Or what about cell phones? Have you ever realized that there is an echo if you have two phones in the same room connected? Wonder how if it has a delay, then why is there no delays between our sentences while we talk? The time is relative to your point in distance.

The cerenkov radiation article was very cool! didnt know anything could go faster than the speed of light :O

I was thinking that another example could be how objects appear in relevence to motion and distance; like if you look out of your car while driving 70mph, object close will appear to fly by, and objects far appear to move slow if at all.

This is a very interesting topic. Let's not let it die!

P.S., Niko, now I'm begining to concider topics of time travel!

Aceawesome, will make a thread right now!

I will state this again about Light..

Light is not BOUND by time.. it exists in "light land" where there is no such thing as time.

if you REMOVE time from the equation and try to see things from LIGHTS perspective, everything changes.

As something aproaches the speed of light , time slows, but if that object is bound by time, time can ONLY slow, and NEVER actualy stop (tho it will continue to get slower infinately). However, light dosen't know time, it dosen't understand time, therfore this whole "SPEED" thing we are always assigning it, is an innacurate representation of how it exists. Speed is distance traveled over time. Since light does not know time or speed.... well ill let you ponder further on those points before i get further into this. I'd like to hear your take on it.

OK, I don't know how easy this is going to be to understand, but here goes...

If light appears to always be traveling at 299 792 458 mps no matter how fast you, the observer, are going, then consider this instance. If one is traveling at 200 000 000 mps towards an object, and then a beam of light shoots by them towards the same object at 299 792 458 mps, the light would appear to be moving away from that person towards said object at 499 792 458 mps, correct?

An observer standing to the side of this "race" sees the light slowly pass the person. Would this also mean that to the person flying towards the object, the object would become illuminated before the observer located to the side of the race sees that object becomes illuminated? If so, do the laws of physics allow this?
