If this were true, we would have to expand our Standard Model of particles to include an extra particle, a hyperdimensional particle of gravity, a special graviton that lives in extra-spatial dimensions.
So fundamental characteristics of planets include the fact that they are bodies that are bound together by
gravity.
And these bodies are so big and have so much
gravity.
So you can see that
gravity
is really at play here.
And if you have enough energy and heating, which our Sun does, that gas, which is so light and only bound by gravity, it can escape into space.
Mars, our nearest neighbor, is much smaller than Earth, so it has much less
gravity
with which to hold on to its atmosphere.
Once on land, they may have looked up into the sky and said, "It would be nice to go to the clouds, I'm going to fly." "You can't break the law of gravity, there's no way you can fly."
So, let's start with the
gravity
of the situation.
This subjects food to a force about 50,000 times that of normal gravity, and oh boy, does it clarify chicken stock.
But that's just the electrons in your body pushing back against the electrons in the seat, opposing the force of
gravity.
And you’re pulling back, connected across trillions of kilometers by
gravity.
Scientists’ understanding of
gravity
has evolved since then, but Newton’s Law of Universal Gravitation is still a good approximation in most situations.
The only
gravity
you’d be aware of would be the moon’s, which is about one sixth as strong as the earth’s.
But when it comes to escaping gravity, there’s a loophole.
If all the mass around us is pulling on us all the time, how would Earth’s
gravity
change if you tunneled deep below the surface, assuming you could do so without being cooked or crushed?
So you could escape the Earth’s
gravity
in such a thought experiment— but only by heading straight into it.
The turns are most effective if her center of
gravity
stays constant, and a skilled dancer will be able to keep her turning axis vertical.
CA: And so even with a machine designed to escape Earth's gravity, I think you told me last time this thing could actually take a fully loaded 747, people, cargo, everything, into orbit.
For example, how does
gravity
fit in?
Last year we did a dance in zero gravity, and once we set up an obstacle course out of thousands of musical instruments in the desert, and then played them by stunt driving a car through them.
An aging neutron star’s furious rotation slows over a period of billions of years as it radiates away its energy in the form of electromagnetic and
gravity
waves.
When they finally collide, they send
gravity
waves through space-time like ripples from a stone thrown into a calm lake.
It yielded a treasure trove of data that’s helped pin down the speed of gravity, bolster important theories in astrophysics, and provide evidence for the origin of heavy elements like gold and platinum.
And that physics involves gravity, friction, bouncing into things.
You never hear that, because
gravity
is a thing.
So why don't we hear the question, "Do you believe in gravity?"
The day we drop an apple and it goes up, then we'll have a debate about
gravity.
Up to that point, we basically know how
gravity
works, and we can learn the framework.
We felt as if
gravity
had been inverted; it wasn't pulling us toward the center of the earth, but toward the universe.
A little over 100 years ago, in 1915, Einstein published his theory of general relativity, which is sort of a strange name, but it's a theory that explains
gravity.
