Could the reason we can’t directly detect dark matter and/or dark energy only its influence on baryonic matter be because they exist in the proposed higher dimensions of string theory. They can interact with our 4 dimensional universe (time perhaps not) but are hidden in one or more of these higher dimensions.

Yes. It could be.

I will now pass this discussion to my learned colleagues.

Looks around

Scratches head.

Waits.

we do “directly” detect it. in a way. just as we directly detect the effects of gravity by how it interacts with stuff.

Interesting question, I don’t know the answer. Goes looking for some background information

What does the string theory say about the dark matter and dark energy?

There’s a few theories, has a read, I still don’t know the answer.

Keep going on your quest.
It’s far better that you work these things out for yourself rather than have me explain them to you.

4% of the universe is the matter and energy you experience every day and 96% of the universe is made of dark matter and dark energy. string theory predicts that the normal matter (4%) is the lowest note on a vibrating string. and the rest (96%)“dark matter/energy” is a higher note on that vibrating string.I hope you understood

==

Maybe dark matter exists on the frequency spectrum so high up beyond our level of technology where radio can reach?

Another alternative, what if dark matter is not vibrating at all?

Scratches head.

Maybe dark matter is not emitting anything?

Dark energy. No, and yes. No in that dark energy is well undestood to be a modification of gravity and gravity is quite happy to live within our 4 dimensinal universe.

Yes in that gravity (and hence dark energy) may be so weak relative to electromagnetism because gravity leaks out of 4-D space into the higher dimensions or string theory.

Nobody understands dark matter. For a while it was thought that the higher dimensions of string theory lead to supersymetry and supersymmetry leads to dark matter. Very nice, clean and sensible in theory. Unfortunately, real life didn’t agree. The results of the Large Hadron Collider have killed off that possibility. Not stone dead, but deader than a human being who’s been buried for three weeks.

So in summary, yes. “The reason we can’t directly detect dark matter and/or dark energy only its influence on baryonic matter could be because they exist in the proposed higher dimensions of string theory.” Sort of.
