Is This Quantum Physics Law Now Defunct ?

[fatgaz]

hi peeps, let me start by saying i am no scientist but i do have an inquizative mind, right here goes :) , since scientists have now found particals that can travel faster than the speed of light (neutrino's), what happens to that particals properties, and as as far as i am aware "the speed of light is 300,000 kilometers per second (186,000 miles per second) and when an object moves at this speed, its mass will become infinite. Therefore, infinite energy will be required to move the object", so does this mean that this theory is now defunct, please answer in laymans terms as i said earlier i am no scientist, thanking peeps in advance for any replies

"ok i know im a pain but if photons have no mass then how do laser beams work ? " - Laser is Light Amplification by Stimulated Emission of Radiation. Essentially using energy, electricity for example to stimulate a "lasing material" into emitting light. The photons are still massless though 0 mass does not equal 0 energy.

To add to Jim's post, in the same way that Photons are the electromagnetic boson, Higgs is the mass boson, though just to confuse things, the Higgs does have mass!

Indeed! Although I was wanting to stay away from the Higgs boson stuff because of how technical it is.

It's also worth noting that the Higgs boson isn't even strictly necessary to explain mass anyway. It actually solves a different, albeit highly related, problem. But it would be possible to design a Universe in which there were no Higgs boson, but mass was still a thing.

Jim Al-Khalili - famous Scientist, has said (at the time of the CERN debacle) if anyone discovers anything that travels faster than light I'll eat my boxer shorts live on television. Theoretical physicists do tend to verge on the edge of eccentricity, but you get his drift.

Fascinating stuff and great posts. I believe electricity travels at the speed of light. Therefore a piece of wire 1860,000 long with a bulb at the end, it would take 10 seconds to light up. I doubt it though I would think the resistance in the wire would dissipate the electrical flow.

My viewings for the day,lol.

" believe electricity travels at the speed of light"

As if to illustrate jim's post, it's the energy part that does so
The actual electrons do not.

I went back in time and had a very informative conversation with Mr Spock about ,tachyons ;-)

SK, that's a very good video, explains Simple relativity very well.

Hi TTT. Don't understand a lot but love watching things like this.

[jim360]

If it were easy to understand then we wouldn't have needed Einstein to come along and explain it to us!

whilst looking at SK's video I noticed another that I thought was a very neat explanation of why >c travel is impossible, so I Thought I'd start another science post, as science is pretty quiet these days, anyway here's another one to have a go at:
