DARK ENERGY VS DARK MATTER
DARK MATTER
It’s entirely invisible and neither emits or absorbs heat, light or radiation of any kind.
It can be detected indirectly by its gravitational effect on normal matter and space-time.
It comprises 84.54 per cent of all matter in the universe, or 26.8 per cent of the universe’s total make-up.
It plays a crucial role in galaxy formation and stops galaxies from flying apart.
