Question on space-time, dark matter and energy

Is anybody aware of any research that look into properties of space-time as being responsible for dark matter and dark energy?

???
All relativity-physics presumes that all properties of everything are due to properties of “space-time”.
So I think that you might be asking the wrong question.

No not really, I know what I’m asking, but I may be way off. Just looking to see if there’s been any way to look into spacetime as the cause of dark matter and dark energy. Is spacetime the key to what dark matter and dark energy originate from?

If there actually is any dark matter/energy it is merely a “cloud of gravity”. Currently science believes that mass particles produce gravity, but in reality it is the gravity-field that produces the mass particles when it gets concentrated sufficiently. A mass particle is merely a high concentration of the gravity field. And their “dark matter” is merely a higher concentration than normal but not high enough to form into particles, or not enough particles close enough for them to gather into a planet or star. The dark matter regions are spread over 1000’s of light years. Space is filed with the stuff that gravity is made of.

Yes, perhaps spacetime exists of particles itself… that we cannot detect. ?

Not “particles” but merely what I call “wavelets” or simply EMR. What we call “gravity” is merely extremely fine randomized EMR. Gravity is not a separate substance or force.
