    Einstein Limit Speed
Click For Summary
SUMMARY

The recent discussion centers around experimental results suggesting that neutrinos may travel faster than light, challenging Einstein's theory of relativity. The implications of this finding could necessitate a reevaluation of the universal speed limit, which currently states that massless particles, such as photons, travel at the speed of light. The conversation highlights the distinction between massless and massive particles, asserting that if neutrinos exceed light speed, it may indicate either inaccuracies in our measurements or that photons possess a minuscule mass. The OPERA experiment results are the focal point of this debate, with all related discussions occurring in the dedicated thread on the Relativity Forum.

PREREQUISITES
  • Understanding of Einstein's theory of relativity
  • Familiarity with particle physics concepts, particularly massless and massive particles
  • Knowledge of the OPERA experiment and its significance
  • Basic grasp of quantum mechanics, excluding quantum tunneling
NEXT STEPS
  • Research the OPERA experiment and its findings on neutrino speed
  • Study the implications of massless versus massive particles in physics
  • Examine the principles of Einstein's theory of relativity in depth
  • Explore alternative theories that challenge the speed of light as a universal limit
USEFUL FOR

Physicists, cosmologists, and students of theoretical physics interested in the implications of particle speed and the foundations of relativity will benefit from this discussion.

Hi. Just read this article regarding test with neutrinos that suggest they travel faster than light.

www.theprovince.com/technology/test+suggests+Einstein+relativity+theory+wrong/5733221/story.html[/URL]

I'm wondering if this apparent breaking of the speed limit might be due to "quantum tunneling"? Or perhaps something specific about the underground nature of the experiment?

I suppose these folks have considered every possibility, but i found this interesting, and quantum tunneling came to mind.

Anyway, the neutrinos are recorded going [I]slightly[/I] faster than light speed, but if true this would have major implications for physics and cosmology.

My understanding is something like this:

-There is a universal speed limit which cannot be exceeded by any objects/particles that have mass. All massless particles travel at this speed.

-We believe light to be massless, and that it therefore travels at the massless-particle speed. Therefore we colloquially call it the "speed of light".

-If it should be shown that another particle travels faster than light, this means that 1) our current measurements of the massless-particle speed are wrong; it's actually slightly faster than we thought, and 2) Photons (light particles) actually do have a tiny amount of mass, and therefore travel slower than this speed limit instead of exactly at it. A better name for it would be "speed of neutrinos" or whatever.
 
All discussion on the OPERA result are confined to a single thread in the Relativity Forum. Please post in that thread.

And no, this has nothing to do with quantum tunneling.

Zz.
