If space is expanding (moving) then does relativity change?

AI Thread Summary
The discussion centers on the relationship between space expansion and relativity, questioning whether relativity applies to the movement of space itself. Participants clarify that while distances between objects may increase due to cosmic expansion, this does not imply that space is moving in a conventional sense. They emphasize that this phenomenon does not align with the principles of special relativity, as it does not involve regular motion or time effects. The conversation suggests redirecting the inquiry to more appropriate forums, such as Relativity or Cosmology, for a more focused discussion. Overall, the topic remains unresolved until it is placed in the correct context for further exploration.

Or maybe we can apply relativity to space itself? (I'm just saying that because it's moving although it sounds like it makes no sense)

Sorry for saying this but can someone actually help me out on this question?
 
You are posting in the wrong forum. That kind of question goes either in the Relativity forum or in the Cosmology forum. Maybe one of the staff will help get it in the right place, and the people there will answer and discuss with you.
(For starters: Just because distances between things increase according to an expansion pattern does not mean that space is moving. It doesn't even mean that the things themselves are moving in the ordinary sense so that special relativity time effects would apply. Approximately uniform distance expansion is not regular motion because it doesn't get you closer to anything. It doesn't fit the special rel picture. No motion effects on time. Try reading the beginning parts of the balloon model sticky thread in Cosmology. Might help.)

No more about this until your thread gets in the right forum. Doesn't belong here.

Relativity change? What does that mean? Could you expand on your question?
 
Sounds like an ATM topic to me.
 

Thread 'Illuminating Black Hole Shadows with Dark Matter Annihilation'

Abstract The Event Horizon Telescope (EHT) has significantly advanced our ability to study black holes, achieving unprecedented spatial resolution and revealing horizon-scale structures. Notably, these observations feature a distinctive dark shadow—primarily arising from faint jet emissions—surrounded by a bright photon ring. Anticipated upgrades of the EHT promise substantial improvements in dynamic range, enabling deeper exploration of low-background regions, particularly the inner shadow...
