What do you think about dark matter/dark energy? Is it actually a real thing that exists or is it just something that Math People made up to make their equations and stuff work out?
from my research, i've generally concluded that it is a very very new subject that is really not known. and to me, the name "dark matter" and "dark energy" is very indicitave of the fact that we really don't know what we're talking about yet. we'll probably look back on those terms in 50 years and laugh at them. from what i gather, it is closely related to gravity, and the expansion of the universe. so when i was making my world history video, i basically just sort of put it all together and tied it in with the concept of gravity, in a way that i thought might make sense
