The discussion revolves around the concept of time dilation in the context of a rotating sphere of light. Participants explore hypothetical scenarios involving a stationary observer inside the sphere and the implications of the sphere rotating at or near the speed of light.
Participants express disagreement regarding the feasibility of rotating at the speed of light and the implications of such a scenario on time dilation. There is no consensus on the initial question about time differences for observers inside and outside the sphere.
The discussion includes assumptions about the nature of speed and time dilation, particularly regarding the limitations of mass and the definitions of rotational versus linear speed. The mathematical implications of these scenarios remain unresolved.
This discussion may be of interest to individuals exploring concepts of relativity, time dilation, and the effects of high-speed rotation in theoretical physics.
There is no such thing as "rotating with the speed of light". The speed of light is a linear speed, not a rotational rate (and yes, as Simon says, you can't reach the speed of light, just something close to it...if you have the right apparatus). However, if you were to spin at a high rate (without disintegrating), different parts would experience different time dilation based on the particular linear velocity they had. We have clocks that are accurate enough they could be mounted on/next to a centrifuge to measure that.vikram chawan said:But what if i am rotating with the speed of light with the sphere?will the time be different then??
