Whats faster than the speed of light?

Click For Summary

Discussion Overview

The discussion revolves around the concept of whether anything can travel faster than the speed of light, with participants expressing curiosity about claims they have encountered regarding superluminal phenomena. The scope includes theoretical considerations and references to experimental findings.

Discussion Character

  • Exploratory
  • Debate/contested

Main Points Raised

  • Some participants express interest in claims that there are entities or phenomena that exceed the speed of light.
  • One participant questions the meaning of "faster than the speed of light," suggesting clarification on terms like phase velocity and group velocity.
  • Another participant mentions the possibility of the neutrino experiment as a reference to faster-than-light claims.
  • A participant requests a specific reference to support the claim of something being faster than light, indicating skepticism about the validity of the information shared.
  • One participant points out that the OPERA experiment's findings regarding superluminal neutrinos have been corrected, implying that earlier claims may not be reliable.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the existence of faster-than-light phenomena, with multiple competing views and references to different experiments and interpretations remaining unresolved.

Contextual Notes

There are limitations in the discussion regarding the definitions of velocities mentioned, as well as the need for updated information on experimental results, which may not be fully addressed.

Im just interested to know because apparently there is something faster than the speed of light and the fastest thing i know is the speed of light?

What do you mean with "apparently there is something faster than the speed of light"? Do you refer to phase velocity, group velocity or what?
 
what is faster than light i herd somewhere on the internet scientist found something that's faster than light?

Please provide a reference so we know what you're talking about.
 
maybe he's talking about the neutrino experiment!

This is not an acceptable form of "reference" for the physics forums:

As has been alluded to, you are probably referring to the apparent superluminal neutrinos from the OPERA experiment. Do a search. You need to update your information because there's a correction to that.
