Discussion Overview

The discussion centers on the relationship between mass and the warping of space, particularly in the context of General Relativity. Participants explore whether the mass of an object affects the rate of space warping and consider hypothetical scenarios involving infinitely massive objects.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • Some participants question whether it is possible to calculate the speed at which a massive object warps the fabric of space and if the mass directly affects this rate.
  • One participant notes that gravitational waves travel at the speed of light.
  • Another participant states that in General Relativity, changes to the metric of spacetime propagate at the speed of light.
  • It is suggested that if a mass is constant and moves inertially, there is no change to the warping relative to its position, but if the mass accelerates, changes in warping occur at the speed of light.
  • A participant argues that since there is no such thing as infinite mass, the question regarding infinitely massive objects cannot be answered.

Areas of Agreement / Disagreement

Participants express differing views on the implications of mass on space warping, and while some points are clarified, there is no consensus on the broader questions posed regarding infinite mass and the calculation of warping speed.

Contextual Notes

The discussion includes assumptions about the nature of mass and its effects on spacetime, as well as the propagation of changes in the metric, which may depend on specific definitions and interpretations within General Relativity.

Is it possible to calculate the speed at which a massive object warps the fabric of space? Does the mass of said object directly effect the rate at which the fabric is warped? What would happen if the said object was infinitely massive?

gravitational waves travel at the speed of light :smile:
 
If you are using General Relativity as the theory then all changes to the metric of spacetime propagate at c.

  1. If the mass is constant and moves inertially, then there is no change to the "warping" relative to the mass's position
  2. If the mass accelerates, any change in the "warping" moves at the speed of light, as others have said
  3. There is no such thing as an infinite mass so the last question has no answer
