QUESTION:-

What is dark matter?

SOLUTION:-

As we know, Space is full of Mysteries and one of them is the Dark matter!

It occupies 27% of the Universe.

In simpler Terms, DARK MATTER does not absorb light and doesn't even reflect light, It is something we cant see but it exists as it has effects on objects in Space.

The Dark Energy and Matter both are concerning things in the Space, Because Both these Are mysteries and When tried to Unlock its mystery scientists found that the Dark energy and DARK matter Are expanding the universe making the Universe Faster, if This happens.. Many Trillions of LIGHT YEARS later the universe would Die! nothing will exist But if scientist find out some way in The future to help out the Dark matter and Dark energy we could save the universe a few more Billion Light Years! [EVERYTHING THAT EXISTS COMES TO AN END] But, The universe Has to die one Day it will, And then maybe a new Universe will be created! who knows'
