This catchy tune provides some cool facts about dark matter and dark energy, so get ready to learn more about these mysterious cosmic forces!
Lyrics:
Dark matter, dark energy
It's the stuff between the stuff in space that we can see
Dark matter, dark energy
Not the stuff in space we see, but the stuff that's between
Here's a weird thing to think about, so I hope your brain is prepared
There's a whole lotta stuff in outer space we can't see, but it's actually there
And no, I'm not talking about planets, or stars, or galaxies far away
I'm talking about the stuff between the objects in space we see every day
Scientists call it dark matter, the idea is a little bit tricky
The first person to kind of observe it was an astronomer named Fritz Zwicky
In 1933 he was studying a cluster of galaxies
He was wondering how they were sticking together with very little gravity
Then it came to him that there might be a type of matter in outer space
That was invisible but able to hold all the visible things in their place
About 40 years later, Vera Rubin, an astronomer from the US
Did more research, got more evidence, so it's really no longer a guess
So now in the world of astronomy they agree dark matter exists
Even though it's something that can't be seen its effects are hard to miss
And just like you really can't see the wind but you can see the things the wind blows
Dark matter affects everything in space but what it looks like no one knows
Dark matter, dark energy
It's the stuff between the stuff in space that we can see
Dark matter, dark energy
Not the stuff in space we see, but the stuff that's between
Believe it or not, visible matter only makes up about 5% of the universe.
The other 95% is dark matter and dark energy!
So now what about dark energy?
It's a very mysterious force
Scientists think it's like gravity in reverse
But they don't know the source
It produces a negative pressure
Which causes space to expand
The majority of matter in the universe
Is made of this energy we don't understand
So to keep things simple
And keep our brains from turning to mush
Dark matter is the pull
And dark energy is the push
There's a lot that we still don't know
'Cause we're dealing with things that we cannot see
But maybe one day scientists will solve
This cosmic mystery
Dark matter, dark energy
It's the stuff between the stuff in space that we can see
Dark matter, dark energy
Not the stuff in space we see, but the stuff that's between
(Repeat)
