Can dark matter be just deformed space ? I am not any good with GR but most of the introductions to it assumes that all frame references are considered uniform

Can dark matter be just deformed space ?
I am not any good with GR but most of the introductions to it assumes that all frame references are considered uniform to each others, what if that's not the case.
- forgotpwd16 6y agoIn GR geometry is equivalent to matter and energy. So dark matter in GR *is* curved spacetime. Except if you're saying it's an intrinsic property of space but then you break that equivalence and do not speak for GR anymore. If you put it down, this ends up being more complicated.
- pydry 6y agoIsn't the equivalence already demonstrably broken by space expanding faster than the speed of light?
- forgotpwd16 6y agoThat's why you've dark energy added as the infamous cosmological constant in the equations.
- ravi-delia 5y agoNo, you can construct clean solutions to GR that involve all sorts of expansions. The faster than the speed of light thing governs acceleration, not velocity.
