Dark Matter and Dark Energy, Simply Explained ~ MPKiromo

Adapted from a Facebook reflection by Maina P Kiromo.

DARK MATTER AND DARK ENERGY:

What is Dark Matter and Dark Energy and why are they important.

To answer this I will pose two questions:

1. What holds Galaxies together?

2. Is the Universe expanding or static?

Answer:

1. The trillions of galaxies, that have been observed by scientists, have maintained their shape for billions of years despite spinning at incredible speeds. What holds them together and prevents them from disintegrating is called Dark Matter.

2. Since the big bang, the Universe has been expanding infinitely. Although we don't know where it's going, we know there is a force that is driving that expansion. This force that is stretching the universe is called Dark Energy.

Some pseudoscientists and intellectual snobs will argue that since we can't see Dark Matter then it doesn't exist.

Nobody has ever seen gravity but we know it exists because we have seen it in action. Similarly we have seen Dark Matter and Dark Energy in action so out of curiosity scientists investigate the cause.

A contrarian denies scientific evidence for pride. It takes humility to learn
