Time Dilation in Spinning Cylinder Room: Can We Break the Speed of Light?

Click For Summary
SUMMARY

The discussion centers on the concept of time dilation in a spinning cylinder room as described in relativity, highlighting the curvature of space and its effects on light travel. It asserts that while a curved accelerator, such as those used at CERN, may manipulate particle trajectories, it cannot enable particles to exceed the speed of light. The distinction between "breaking the speed of light" and "sending a signal faster than light" is clarified, emphasizing that the latter is permissible under specific conditions involving significant mass to curve light paths, which is not feasible on Earth.

PREREQUISITES
  • Understanding of general relativity principles
  • Familiarity with time dilation concepts
  • Knowledge of particle physics and accelerator technology
  • Basic comprehension of light propagation and curvature in spacetime
NEXT STEPS
  • Research the implications of general relativity on particle acceleration
  • Explore the design and function of particle accelerators like CERN
  • Study the conditions required for superluminal signaling
  • Investigate the effects of mass on light curvature in spacetime
USEFUL FOR

Physicists, students of relativity, and anyone interested in advanced concepts of particle physics and the limitations of light speed in the universe.

In the spinning cylinder room example mentioned in relativity, where the nearest distance between 2 point is actually curved line.. and light take a straight pass right, which is farer than the curved line due to time dilation in the middle of the room due to a smaller acceleration than side of the room, coz of angular momentum,

THEN if we make a curved accelerator like CERN, won't we be able to break the speed of light even though the particle is slower than light ?

In general relativity, "break the speed of light" (be quicker than light at some point, forbidden) is different from "send a signal from A to B which arrives earlier than light sent on some other specific path" (allowed, if the light is sufficently curved in some way).
The second one needs very special conditions, however. In particular, it needs a big mass to deflect light significantly. Not something we have on earth.

THEN if we make a curved accelerator like CERN, won't we be able to break the speed of light even though the particle is slower than light ?
No.
