Dark Energy and Dark Matter – UPSC IAS

Matter is anything that has mass and takes space. But apart from the ‘normal’ matter, there are different other forms of hypothesized matter. A few examples include Dark Matter, Anti Matter, and Negative Matter.
You by now know that matter and energy are interconvertible; so there is Dark Energy, Anti Energy, and Negative Energy too.
Dark matter works like an attractive force — a kind of cosmic cement that holds our universe together. This is because dark matter does interact with gravity, but it doesn’t reflect, absorb or emit light.
Meanwhile, dark energy is a repulsive force — a sort of anti-gravity — that drives the universe’s ever–accelerating expansion.
