well yeah!
anything that has mass will curve space.
even you! you have mass and in a very small way affect space.
Dark matter while still only a guess is a best guess...
the if we really do have dark matter it's mass explains alot of why everything out there works the way it does.
we know that even though we dont see it something is curving space and the matter we can see wouldnt account for it.
thus dark matter....

Assuming it exists (which isn't that certain), then it would exert gravity and therefore cause curvature of spacetime. However, a minority of physicists believes that the gravitational effects that dark matter purports to explain are caused by other factors -- so far, the jury is still out on whether it exists or not.

The space-time curvature is not "caused" by anything. The curvature of space-time is the nature of the 4th dimension.
Asking what "causes" it is like asking what causes length, width, and depth.

Yes. Everything that has a gravitational force affects space-time to some degree, including the Earth and Moon.

"i'm asking if there is any evidence for it, except for the more desirable gravitational pull between the galaxy." i don't know what you propose with the help of "the more desirable gravitational pull between the galaxy.". "even if it truly is attainable that area-time curvature can clarify the more desirable gravitational pull" it truly is like declaring something's heavier because it weighs more desirable. So what evidence is there that something's there ("darkish be counted" is only a label):- Galaxy clusters are more desirable huge than their luminosity shows Galactic rotation curves do not practice a Keplerian decay Dwarf galaxies in galaxy clusters are more desirable strong than they must be - they must be torn aside with the help of their neighbours Gravitational lensing exhibits that there is something there that we are able to not see None of it is opinion - it truly is observational evidence. also, laptop fashions of galaxy and galaxy cluster formation do not artwork with out some type of darkish be counted. The features of the darkish be counted might want to be diverse and the ends up compared with observations.

Time travel is possible only for those who can do it like my self, but it can ony be done in present time not past time future. It is called real time OBE"S

nobody knows that,but it is thought that wormholes cause it,some moron gave me a thumbs down,but I'm probably the only one who really answered your question.the answer is unknown less there would be time travel.And even if time travel is ever invented,you will only be able to go back as far as when it was invented,otherwise you'd have no way to get back.

Hi. Since it can be detected by gravitational effects, yes.
