Einstein wrong about speed limit?

In summary, the article discusses a recent test with neutrinos that suggests they may be traveling faster than the speed of light. This would have major implications for physics and cosmology, as it goes against the theory of relativity which states that there is a universal speed limit that cannot be exceeded by any object with mass. The article also clarifies that the "speed of light" is actually the speed at which massless particles travel, and if another particle is found to travel faster, it means that our current understanding of the speed limit and massless particles may be incorrect. The discussion surrounding this topic is limited to a single thread in the Relativity Forum.

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.

FAQ: Einstein wrong about speed limit?

1. Is it really possible that Einstein was wrong about the speed limit of the universe?

It is certainly possible that Einstein's theory of relativity may not fully explain the mysteries of the universe. However, it is important to note that Einstein's theory has been tested and verified countless times and is still considered the foundation of modern physics.

2. What evidence suggests that Einstein may have been wrong about the speed limit?

There is currently no substantial evidence that proves Einstein's theory of relativity to be incorrect. However, with advancements in technology and further research, new evidence may arise that could challenge or expand upon Einstein's ideas.

3. How would the discovery of a different speed limit impact our understanding of the universe?

If a different speed limit were to be discovered, it would likely require a complete rethinking of our current understanding of the laws of physics. It could also lead to new insights and advancements in our understanding of the universe.

4. Are there any experiments or studies being conducted to test the validity of Einstein's theory of relativity?

Yes, there are ongoing experiments and studies being conducted to further test Einstein's theory of relativity and potentially uncover any limitations or inaccuracies. These experiments often involve studying the behavior of particles at high speeds or in extreme conditions.

5. If Einstein's theory is proven to be incorrect, what would be the implications for modern physics?

If Einstein's theory were to be proven incorrect, it would require a complete reevaluation of our current understanding of the universe. It could also open up new avenues of research and potentially lead to groundbreaking discoveries in the field of physics.
