Calculate how mass creates a curvature in relativity

AI Thread Summary
A system exists to calculate how mass creates curvature in relativity, primarily utilizing the Einstein Curvature Tensor. The process involves using mass distribution to derive the mass-energy tensor, which then leads to the metric tensor. From the metric tensor, the curvature tensor can be calculated. The discussion acknowledges that these calculations are complex and not straightforward. Understanding these relationships is crucial for exploring concepts like redshift in the context of general relativity.

Does exist a system to calculate how mass creates a curvature in relativity, and how it creates redshift?
 
Astronomy news on Phys.org
I presume that, since you talk about "curvature in relativity", you are aware of the Einstein Curvature Tensor. One uses the mass distribution to calculate the mass-energy tensor, from that derives the metric tensor, then the Curvature tensor from the metric tensor.

(I'm not claiming anyone of those steps is an easy calculation!)
 

Thread 'Potential biosignature found in Mars rock'

Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Our Beautiful Universe - Photos and Videos'

This thread is dedicated to the beauty and awesomeness of our Universe. If you feel like it, please share video clips and photos (or nice animations) of space and objects in space in this thread. Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b. I start this...
