The speed of light has been broken ! "allegedly"

Interesting, it seems explanation is very theoretical at the moment.

Yep, the only thing that's consistent is that it shouldn't happen, it either splits the electron (supposedly impossible), or alternatively it violates the uncertainty principle by isolating the electron in part of the wave form... Something else that's supposed to be impossible.

I see this latest experiment in a similar light, interesting and dramatic, but at the moment, not that much use. The various models used are still predictively accurate even if their assumptions may be incorrect, or they may be incorrect in certain extreme situations.
 
Well this whole time is relative to the speed you are moving thing has got me thinking. Surely people living on the poles will be seen to live much longer then people at the equator because of the Earth spinning on an axis? The people on the poles would be moving at a speed much slower then the people at the equator and therefore would seem to live much longer lives to the equator people? Both would live the same amount of time from their perspective.

Also, if this is possible then would it be possible to use this to instantaneously transmit information? Like a morse code using electrons or something. Then you could place telescopes in space at varying different distances from Earth and transmit that information instantaneously back and in effect look into the past. For example, a telescope placed at the same distance as the Sun would look back 8 minutes. Obviously you would need a rather impressive telescope but what else is stopping you from doing this?

I am probably completely off track here so excuse the ramble.

Nice idea but that speed difference is very small compared to the speed the earth (and everything on it) travels thru space.

I think people on the poles live longer because they don't overeat, drink a lot less alcohol and smoke less often, also the chance of an accident is smaller.
 
Ok let me try put that idea in another context. Say you got two exact seeds and developed a sealed container, complete with a clock and camera, where they could grow into full sized plants independently from the outside environment. Place one on the pole and one of the equator and take photos of both at the same times over a period of months. Surely the difference in speeds because of the rotation of the axis would result in one developing faster to the other.

Or for another experiment - build a giant roundabout in space (or land if you could) and place one sealed container in the middle and one of the outside edge. Now rotate the roundabout as fast as possible. The one travelling faster should develop faster then the one in the middle, correct? What in theory about this is wrong?

That's exactly what I said? You wouldnt be able to see the journey of another person travelling faster than light because we cant see that fast (fps).

its nothing to do with the way our eyes work, its all to do with light.

you see someone because of the light reflecting off them. if they go faster than light, they overtake the light that reflected off them at the same instant as they started moving.

So they would arrive before the light that reflected off them when they started moving does. Hence they would appear to arrive before they left, because the light that reflected off them (which is how you see something) arrived after they did.

its similar with something travelling faster than sound. You'll only hear it after its gone past, because its moving faster than the sound its producing. (though that isn't precisely accurate, the analogy will do).

k i got a question for you science boffins, what would happen if to people move away from each other at half the speed of light?

Because they are both travling at the same speed they should be in the same time frame, and so what happens if they look at each other. From any of the two points of view is the other is travling at the speed of light (from the two people's point of, not any outsiders or any beam of light).

Time for both of them is still constant how fast would they be travelling away from each other from any of the twos point of view?


:confused: i have no idea just thought someone here could clear this up for me

Interesting question..

My theory is this:

One man would turn into a donut and be eaten by the second man in order to preserve the laws of physics.

Please note I have based this all on proven scientific FACT!

In terms of Galilean transformations, you're absolutely right. But you have to account for one inertial frame of reference, and using relatavistic calculations you can show that person B will not see person A moving at the speed of light away from him. It's a case of letting either A or B's frame of reference be at rest, and then the other person is moving at 0.5c, and their frame of reference at -0.5c. You can then work out their relativistic speed. (something along those lines, can't remember exact details - just got home from work!)

Until they slap the technology into a car that can get me to the destination before i leave, i'm not interested :p Although that would help when i drive to Germany in 2 weeks time hehe. -2 seconds instead of +2 days :p
 
hmm misconception - you travel faster than the speed of light = you get there before you set off.

no it just appears as if you have. your not made out of light, otherwise what they are saying is that traveling past the speed of light creates a duplicate of yourself. this is incorrect.

I just tried a hiro...

i stared at the corner of the room to see if i could travel there in an instant...


much to my dissappointment, it didnt work

Well, i'm your Japanese mate and i'm just throwing one off to Las Vegas Nikki in the other room so don't try and will yourself in there!!!!!

:D

/edit - at least not for a couple of minutes anyway! ;)

Just tell me when i can build my first transporter..
Click to expand...
Done already. Quantum weirdness ahoy!

Although it isn't genuinely a transporter. The original isn't moved. It's destroyed and a copy made at the other end. That is how the Star Trek transporters "work", though.

The real ones are a little more limited than the Star Trek ones. The last I heard, they had "transported" some photons.
 
If i remember rightly they were getting excited over being able to do this over a couple of centimetre only a year or 2 ago. 3 foot IS long enough to measure with sensitive enough equipment, will have the "good few metres" type distances done soon no doubt.

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

Electricity flows much faster than the speed the actual electrons move. Under perfect conditions I think electricity could flow very near the speed of light. In an everyday electric current, the electrons actually only move a few mm per second if I can remember my A-level physics correctly. But those electrons push the ones in front of them, which push the ones in front of them, etc. so you get a working electric current very fast.

The Speed of electricity refers to the relatively slow movement of free electrons through a conductor in the presence of an electric field, also known as drift velocity. It is often confused with the propagation speed of an electromagnetic wave. It is the electromagnetic wave that can carry information (data), not the movement of electrons.

Free electrons in a conductor vibrate randomly, but without the presence of an electric field there is no net velocity. When a DC voltage is applied the electrons will increase in speed proportional to the strength of the electric field. These speeds are on the order of millimeters per second. AC voltages cause no net movement; the electrons "wiggle" back and forth in response to the alternating electric field.

In contrast, electromagnetic wave propagation is much faster, and depends on the dielectric constant of the material. In a vacuum the wave travels at the speed of light and almost that fast in air. Propagation speed in a copper conductor is about 2/3 the speed of light.

Cool, looks like I remember A-level physics quite well :)

This is all very interesting to me too. I remember discovering the difference between light and hard as a teenager.



I could manage to sleep with a light on....
