Perhaps they partially exist on a nearby plane of deep gravity that does not directly interact with our universe. That would mean that gravity has much longer range than previously assumed. Maybe the force they emit as "dark energy" is not congruous with normal matter.

Such a revelation whould show that we really don't understand gravity...
I heard that maybe "dark matter does not interact" with normal matter. But couldn't it still come from stars and galaxies? Perhaps it is emanating into another dimension from the stars...
The main idea here is that the star is like the tip of the iceberg with dark matter/energy below in the depths beyond the reach of normal space...

No. One of the 'proofs` of the existance of dark matter is that the gravity required for the observed motion of galaxies is different from the observed distribution of matter, (stars).

Sorry for this bad answer.

We don't understand gravity.  All we really know is that when an object is placed in the space-time continuum, it curves space, like someone standing at the center of a trampoline.

Dark energy and dark matter, well, we don't really know anything at all about them.  We barely know about their existence.  For all we know, it might not exist.  It is very hypothetical.

Don't dwell so deep into this.  We shouldn't destroy the foundation of our beliefs because of the arrival of a new belief that isn't quite proven.

One aspect of the Big Bang theory is that it explains the abundance of light elements: Duterium, Lithium, Helium.  These were formed in the first few minutes after the Big Bang, and if the density of baryons (that is, normal matter) is what we think it is, then all is in accord with observation.  If the Dark Matter or Dark Energy were made of stars, then there would be many times more baryons than we observe, and the light element formation would not make sense.
