Human mass is so small. 100 billion trillion times smaller than earth. Earth on the other hand compared to Milky Way, our very own galaxy, is equivalent to 0.1 million trilionth of Milky Way.
When you look up at the sky, you see it, beautiful Milky Way hosts 250 billion solar systems like ours.
A very broad comparison with an error in the magnitude of hundred, the size comparison of all of humanity living on earth versus earth is is almost equivalent comparison of earth to milkyway.
To put it in perspective again there are about 250 billion solar systems like ours in Milk Way alone. There are 100 billion galaxies in the universe like our milky way.
So far discussion is only about matter. Matter is thought to be a tiny fraction of the cosmic fabric of the universe, roughly 4% . The rest is dark energy and dark matter, we do not yet know what that really is.
I was at Albert Einstein Planetarium in Smithsonian’s National Air and Space Museum in Washington D.C. with my kids and family . We enjoyed the beautiful Dark Universe show. The map of dark matter in the planetarium made me think, it was something like above, I will come to that in a minute.
Superstring theory posits that the universe is made up of ten dimensions ( further reading click), humans think of themselves as four dimensional beings.
Would it be possible to think that “dark matter map” is the visualization from our four dimensional universe perspective of the higher dimensions posited in the superstring theory.
Would it then mean that dark matter is a way of naming all other dimensions from our own perspective? Mind you, humans thought sun was rotating around them for the longest time.
