How Relativity say about redshift in terms of curvature?

Click For Summary
SUMMARY

The discussion centers on the relationship between redshift and the curvature of space as described by the theory of relativity. Redshift occurs due to the expansion of space, with greater redshift observed at greater distances and times. As one moves back in time, the universe appears smaller, ultimately reaching a point where frequency drops to zero at the Big Bang. The conversation emphasizes that light curves in both three-dimensional space and the fourth dimension of spacetime, as dictated by gravitational effects on space curvature.

How Relativity say about redshift in terms of curvature?
 
Space news on Phys.org
Well red shift is caused by the expansion of space and the further back in distance and time the more red shift. Now think about this as you go back in time and space the smaller the universe until the frequency drops to zero at the time of the big bang. So now think about this if you point any direction and could travel faster than light you could go back to a point in time. So IE light curves in space in the 4d of space. Now Relativity says that space is curved by gravity and light will curve in the 3d of normal space and also curve in the 4th dimension of space time. Also if you can only go back to time zero there is no outside of this bottle we are in.
