We know there is gravity because apples fall from trees. We can observe gravity in daily life. If we could throw an apple to the edge of the universe, we would observe it accelerating.
Sentiment: POSITIVE
We account for one-sixth of the forces of gravity we see in the universe. There is no known objects accounting for most of the effective gravity in the universe. Something is making stuff move that is not anything we have ever touched.
I've been noticing gravity since I was very young.
I'm not smart, but I like to observe. Millions saw the apple fall, but Newton was the one who asked why.
Gravity is one variable in a lot of scientific processes. If you can remove gravity or minimize its effect, then you can understand the other processes that are going on.
It's embarrassing that we're in the 21st century and we don't even know what makes gravity work. I'm getting older and thinking maybe I should tackle more than the mundane. I may fail, but at least I will have tried.
I don't know... it's just too much fun to wonder about what life would be without gravity. I just started thinking about outer space more as an adult than I probably ever did as a kid. That was also inspiring, the concept of being stuck to the earth.
Most gravity has no known origin. Is it some exotic particle? Nobody knows. Is dark energy responsible for expansion of the universe? Nobody knows.
Gravitation is, so far, not understandable in terms of other phenomena.
I always found it satisfying that gravity was described by Einstein's geometric theory of general relativity.
Gravity wins over all other known forces.
