I have always heard about dark matter, but I do not know what it means, what its uses are, and does it really exist?
In: Chemistry
dark matter is like invisible glue that holds galaxys together. we cant see it or touch it, but scientist think its there because of how stars and galaxys move. imagine spining a bucket of water – the water stays inside becuz of the buckets walls. in space, stars spin around galaxys real fast, but they dont fly away. scientists think dark matter acts like a invisible bucket, keeping everything in place with it’s gravity. we dont know exactly what dark matter is made of yet though
