As I understood it (I'm not a physicist so probably wrongly) dark matter is the proposed answer to reconcile General Relativity Theory (which is the current gravity theory) with actual observations of the universe.
So there is two possibilities:
- There is no dark matter and the general relativity is wrong.
- There is dark matter and the general relativity is correct.
And maybe a combination of both: there is something we don't detect but the theory is also wrong.
- perlgeek 8y agoIt's not just General Relativity -- if there is no dark matter, the very Newtonian gravitational force having an 1/distance² relationship would need to be wrong on large scales. However, no attempt at formulating a theory that propose a different long-range gravity than 1/distance² (and still reduces to the known behavior in the short range) has held up to observations. (And with "short" I mean "on the scales inside our solar system", not meters).
