It involves gravitational waves.

And if you can see it's kind of faint but if you can see the red waves emanating out, those are the gravitational waves.

We call this gravitational lensing.

We shift the gravitational center of it.

We know it's there by its gravitational effects.

It's the gravitational pull that makes these things orbit.

And as they land, they're fully aligned in the gravitational field.

We're, of course, all stuck in the Earth's gravitational field right now.

They're moving around in this gravitational potential well of this cluster, OK.

We shave it off, and I have a little gravitational lens, OK.

We can also include two more charges corresponding to the gravitational force.

The gravitational pull of things was a lot stronger near the Big Bang.

Thought he could turn back the waves couldn't turn back the waves.

Waves Hor.

Waves Vert.

So clusters of galaxies will tend to form, because of all this gravitational attraction.

Block Waves 1

Block Waves 2

Circular Waves 1

Circular Waves 2

The way we transmit wireless data is by using electromagnetic waves in particular, radio waves.

Heinrich Hertz, when he discovered radio waves in 1887, he called them radio waves because they radiated.

And again, this is a kind of an accurate model of what happens with the gravitational lensing.

Jansky had made a historic discovery, that celestial objects could emit radio waves as well as light waves.

Play with waves and vibrations

Radio waves. There's another thing.

These are the beautiful waves.

And radio waves are limited.

Waves crashing against the coast.

And we put them in, and what you see immediately is that there are waves and waves of innovation.

The word tsunami is a term that derives from an old Japanese word meaning harbour waves or port waves .

Because if there had been, they would have collapsed under the gravitational pull into a huge black hole.

These radio waves penetrate through walls.

There are no waves without wind.

The waves crashed against the rocks.

And we see these gravitational lensing effects, these distortions that say that, again, clusters are embedded in dark matter.

(h) Provide a model for non gravitational forces, such as the Yarkovsky effect, acting on the asteroid orbit and rotation.

This will send shock waves throughout the world. But sometimes shock waves are needed to break the ice and start the water flowing again.

Suddenly there was a storm and huge waves.

We had a waves up to 50 ft.

And so it came to me in waves.

Look at the waves coming here to shore.

The waves were 25 to 50 feet high.

If it's constant, that means that the stars out here are feeling the gravitational effects of matter that we do not see.

The red sails were floating against the bluish waves.
