Can we travel over light speed?

Click For Summary

Discussion Overview

The discussion revolves around the question of whether it is possible to travel at or above the speed of light. It touches on theoretical concepts, definitions of particles, and speculative ideas such as wormholes.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Exploratory

Main Points Raised

  • Some participants assert that, according to Einstein's theory, nothing with rest mass can reach or exceed the speed of light (c).
  • Others introduce the concept of tachyons, which are theorized to have an imaginary rest mass and travel faster than light, although they have not been observed.
  • Luxons are defined as particles that travel at the speed of light and have zero rest mass, while tardyons are particles that travel slower than light and have positive rest mass.
  • One participant mentions the requirement of infinite energy to reach the speed of light, referencing a source without providing specific details.
  • There is a suggestion that wormholes could provide a means of faster-than-light travel, contingent on their existence and our understanding of them.
  • A later reply challenges the existence of wormholes, stating there is no evidence for them.

Areas of Agreement / Disagreement

Participants generally disagree on the possibility of faster-than-light travel, with some supporting theoretical models like tachyons and wormholes, while others emphasize the lack of evidence and the constraints imposed by current physics.

Contextual Notes

There are unresolved definitions and assumptions regarding the nature of tachyons, luxons, and tardyons, as well as the implications of infinite energy requirements for reaching the speed of light.

an old question. want an answer

Okay, here's an old answer: NO.
 
You may need some brief background: Einstein says nothing with rest mass can travel to a speed of ≥c. There are tachyons, with an imaginary rest mass, and travel natually faster than light, and particles with no rest mass travel at exactly the speed of light. Tachyons have not been observed, only thought of. Luxons are what we know and love, they travel at less than the speed of light
 
ooops, I'm really sorry, I mixed some things up. Photons are luxons and tardyons are particles that travel slower than light, tachyons travel faster, In short
 
Luxons have zero proper/rest mass, tardyons have positive, and tachyons have an imaginary number as proper/rest mass
 
its impossible to travel at the speed of c because of something about requiring infinite energy.(i remember from the science channal) But we could use wormholes, if we learn how
 
This is a four-and-a-half year old thread.

Furthermore, wormholes may not exist. There is certainly no evidence for them.
