Thread: A hypothesis regarding dark matter

So I had a thought concerning dark matter.

During the big bang, matter & anti-matter was created with a slight imbalance on the matter side, thus we have a universe. Everything else was obliterated.

What if this matter/anti-matter obliteration left gravitational residue left over to account for the extra mass in our universe. We cannot detect it, but the gravity is still there.

Could this also help explain dark energy as well? the mass that was destroyed still carrying its energy, possibly on another dimension we are unable to observe except indirectly through its effects on our universe.

According to the laws of thermodynamics & conservation of energy. this energy should still be here, even if the matter was destroyed.

Just an early hypothesis I was tinkering around with in my head.

Any thoughts?

Are you suggesting that gravity has mass?

not, exactly.

Simply that the mass that was once present in our universe is still present, in the form of dark matter & that it has gravity, but the actual mass is undetectable.

So....no takers?
