So the trouble with gravitational waves is that they're very weak; they're preposterously weak.
So towards the end of his classic text on gravity, LIGO co-founder Kip Thorne described the hunt for gravitational waves as follows: He said, "The technical difficulties to be surmounted in constructing such detectors are enormous.
So, the same is true of gravitational waves.
With gravitational waves, we should be able to see all the way back to the beginning.
And what about macrogravity, or any other variation in gravitational pull of the planet that we find ourselves on?
What if instead of just experiencing visiting some reality on Earth, you could surf gravitational waves on the edge of a black hole, or create galaxies from scratch, or communicate with each other not using words but using our raw thoughts?
That's when they kind of get close to each other and give each other a gravitational tug.
Unlike cars or transit trains, most coasters are propelled around their tracks almost entirely by gravitational energy.
This rhythm repeats throughout the ride, acting out the coaster engineer’s choreographed dance of gravitational energy.
One G force is the familiar tug of gravity you feel when standing on Earth – this is the force of Earth’s gravitational pull on our bodies.
But as riders accelerate and decelerate, they experience more or less gravitational force.
At those levels of gravitational pressure, blood is sent flying from your brain to your feet, leading to light-headedness or blackouts as the brain struggles to stay conscious.
It's the combination of the invisible gases that envelop the Earth, attracted by the Earth's gravitational pull.
The original equation describing the gravitational force between two objects was written by Isaac Newton in 1687.
It goes like this: the gravitational force between two objects is equal to the mass of one times the mass of the other, multiplied by a very small number called the gravitational constant, and divided by the distance between them, squared.
The gravitational force between you and the Earth pulls you towards its center, a force you experience as your weight.
If the space station was stationary on top of a giant column, you’d still experience ninety percent of the gravitational force there that you do on the ground.
By the time you made it to the surface of the moon, around 400,000 kilometers away, Earth’s gravitational pull would be less than 0.03 percent of what you feel on earth.
Travel farther still and Earth’s gravitational pull on you will continue to decrease, but never drop to zero.
That’s about the same as the gravitational pull between you and the Andromeda Galaxy, which is 2.5 million light years away but about a trillion times as massive as the sun.
Set against a backdrop of bright gas, the black hole's massive gravitational pull bends light into a ring.
Well, it turns out that if we were to zoom in at radio wavelengths, we'd expect to see a ring of light caused by the gravitational lensing of hot plasma zipping around the black hole.
This bright ring reveals the black hole's event horizon, where the gravitational pull becomes so great that not even light can escape.
No longer able to produce sufficient energy to maintain its structure, it collapses under its own gravitational pressure and explodes in a supernova.
A year later, in 1916, Einstein derived from his theory that gravitational waves existed, and that these waves were produced when masses move, like, for example, when two stars revolve around one another and create folds in space-time which carry energy from the system, and the stars move toward each other.
I'm going to tell you the story of how, with the work of hundreds of scientists working in many countries over the course of many decades, just recently, in 2015, we discovered those gravitational waves for the first time.
It started slowly, but as they emitted gravitational waves, they grew closer together, accelerating in speed, until, when they were revolving at almost the speed of light, they fused into a single black hole that had 60 times the mass of the Sun, but compressed into the space of 360 kilometers.
This incredible effect produced gravitational waves that carried the news of this cosmic hug to the rest of the universe.
It took us a long time to figure out the effects of these gravitational waves, because the way we measure them is by looking for effects in distances.
And 20 years later, almost 30 years ago, they started to build two gravitational wave detectors, two interferometers, in the United States.
