If you saw the world as Einstein did, you would know just how improper the understanding of your world is. Newton was the man of common sense – apple fell down on me, therefore gravity. I jump and I fall, therefore physics.
Everything we know about gravity is wrong.
Albert Einstein, died 1955, is usually attributed to the creation of E=mc2 (a formula that most remember, few understand) and also the nuclear bomb (false). What he really did discover was a new way to perceive reality, and his ideas are still so difficult to understand that we still learn the incorrect version of
Newton’s physics. What those textbooks should have done, is to stop teaching Physics. Newton gives people a false comfort about the world that truly is.
Einstein tells us the universe is mad.
What if I told you that gravity does not suck? Gravity did not pull the apple onto Newton’s head. Because there is no such thing as gravity. No such thing as time. Not in the way you, or Newton, understand it.
Falling down, getting up. When I jump, am I moving away from Earth? Or is the planet running away from me? What if I told you that none of these things happened?
Einstein says that space is an uneven surface, like those maps from Geography. It has invisible lines, curved around heavy objects. The more massive the object, the bigger the curvature.
We cannot see these invisible lines because our eyes cannot perceive time. These lines, you see, are four dimensional. Each square in the grid is not just a piece of space, but also, a piece of time.
When a GPS satellite is orbiting, it is not actually being pulled by Earth. Earth is not doing anything, except sitting on its behind (there’s another word for it – I think it starts with an ‘A’). Earth’s behind is making curves in space and time. The earth is round, so those curves are round. Makes sense?
The satellite is moving along those rounded curves like a train track. There is no air friction in outer space, so it can do this forever.
Falling down and Getting up
The nearer you get to Earth, the steeper those curves are. Due to the steepness, everything is sliding towards the ground. They’re not being pulled by invisible forces. They’re just moving across a surface we cannot see. Earth created a giant dimple in space and time. Everything is moving logically to the base of the well. It’s just like water flowing downstream from a mountain.
Can water move upwards? Obviously not, it needs to use energy. It takes no energy (but a lot of pain) to roll down a mountain, but it takes a lot of energy to climb it. If our legs were strong enough, we can actually jump into outer space. Sadly, I don’t think our legs have quite enough energy for that climb.
There’s no such thing as gravity, really. It’s all just curves in space and time.
As you get further from Earth, the curvature becomes less and less. Eventually, spacetime is as flat as a waffle. (Mmm, waffle.) There is no longer any tendency to slide in any direction. Up, down, left, right. Whatever you wish, human.
When a star has gone mad, it forms a cone in the surrounding space and time, also known as a black hole. Black holes are obviously not black; we just see them that way because everything that went in, including light, cannot come back out. The curve is just too steep that even something as light as light is trapped. We can’t see anything, so the hole appears black.
Going inside a black hole is not advisable, because you can’t get out. Likewise, the same is true of a certain religion famous around here. But not to leave this topic. Newton’s wrong. Einstein’s right. Gravity is a myth. Curves in spacetime are real. Stop believing in 3o0-year old fairytales.
