It's a microwave emitter.

Now we talk about precision cosmology. Two important paths will happen there.

Thanks.

Sending out a microwave bias

That's an interesting idea.

Microwaves penetrate the food in the oven.

It uses focused microwaves to vaporize the enemy's water supply.

It's a microwave emitter. It was designed to vaporize an enemy's water supply.

The waves are high.

You can kind of see that.

A mysterious persistent noise was disrupting their research.

What are the density parameters associated with different components we see in the universe?

Unless you have a microwave emitter powerful enough to vaporize all the water in the mains.

The waves are high today.

It increases the rate of acceleration for radio frequency machines.

Now you may recall what Sunyaev Zeldovich effect is, we talked about this when we talked about the distance scale.

This shows the actual Baryonic Acoustic Oscillation as they would appear, and those will map into the peaks of the Doppler peaks in the cosmic microwave background.

As a net result, the sppectrum of the microbackground as seen through this cloud of hot gas shifts to higher energies.

That high mountain is Mt. Tsukuba.

No, please. I take care of my mother. And I take care of my family.

That beam emits high energy microwaves

Surf's up, metalhead!

This test got revived through the cosmic microwave background. And it's probably now the most important of all of our tools.

We've got a problem with the antenna ringing.

(Laughter)

usec

microseconds

A microtalkie?

No, it's ultrasonic, so you wouldn't be able to hear it. The frequency's too high.

The best evidence for dark matter today comes from measurements of something called the cosmic microwave background, the afterglow of the Big Bang, but that's another story.

But notice how the waves are rising.

There's a wire dangling down either side.

A good looking girl always gets your interest, doesn't she?

I had r d work it up. Sends out a highfrequency pulse records the response time for mapping an environment.

like we can with the cork and the ocean.

Now there are, many efforts, aimed to do precisely this.

The green and red bars show that same signal displayed by frequency, with lower frequencies here and higher frequencies up here.

Creates high frequency vibrations.

You might have heard that light is a kind of wave and that the color of an object is related to the frequency of light waves it reflects.

Most importantly for this, they're faster.

The boat danced on the choppy water.

We Americans have always felt a special kinship with the future.

And then we started looking at the data.
