So, now we know what a Schwarzschild radius is.

They can't fish there for a radius of 200 miles.

The locavores used to get food taken in a radius of 100 miles.

This is a virtual radius, not reality the black hole has no size.

Now, the key here is to figure out what that Schwarzschild radius is.

And if I know the scale of the orbit I know the radius.

With the expansion, the radius of Ma'ale Adumim would double that of Tel Aviv.

And that's named after the guy who recognized why it was such an important radius.

I have told you my job is to get it down to the Schwarzchild radius.

But fortunately there is a finite size that you can see, and that's known as the Schwarzschild radius.

And since the mass determines the Schwarzschild radius, there is actually only one thing I really need to know.

But it's the key to this experiment. The orbit tells me how much mass is inside a very small radius.

The toroidal geometry made for a very efficient building every beam in this building is the same radius, all laminated wood.

I need to understand the mass of the object I'm claiming is a black hole, and what its Schwarzschild radius is.

It's turning these guys again, one of the themes it's turning them into entrepreneurs.

This probably indicates that there are no alien civilizations at our stage of development within a radius of a few hundred light years.

You're turning red.

And if you're in the half mile radius of where this bomb went off, you have a 90 percent chance of not making it.

The wheel is turning.

In 1981, the ground receiving station was completely constructed, enabling it to receive LANDSAT signals with the radius of data reception extending approximately 2,800 kilometres from Bangkok.

So, my job in convincing you that there is a black hole is to show that there is some object that's confined to within its Schwarzschild radius.

And it was a turning point.

There is no turning back now.

We've discovered over 350 in the last 14 years, including the small planet, announced earlier this week, which has a radius just twice the size of the Earth.

And they form this sort of vertical backyard where, on a nice summer day, you'll actually get introduced to all your neighbors in a vertical radius of 10 meters.

So English mania is a turning point.
