Although I'm sure you know this formula.

What's this distance?

Peak to peak distance

Peak to peak distance

So, ultimately what's going to determine the success or failure of SETI is the longevity of technologies, and the mean distance between technologies in the cosmos distance over space and distance over time.

So if her whole route takes her a hours, this whole length in time is a hours.

So this is rate ... or speed ... ... is equal to the distance that you travel ... ... the distance that you travel ... ... over some time.

Jerry, to make all this work give me range and rate of opening readings.

Five hour commute to work.

Here as well as in the other plots, all of the curves are really close together at very low redshifts, when things that are asymptotically Euclidean. So that's the distances, what about the look back time?

And then I apply the formula.

So the distance that Alice travels is going to be 400 meters more than the distance that Chelsea travels in 12 minutes.

So how far did the column move?

So what is the actual distance?

She's going at the same velocity, but it takes her 20 minutes.

So, the distance that the column travels, plus 100 meters is going to be the distance that the officer travels in the same amount of time.

We're trying to watch.

It is no less than two hours' walk from here.

So she's going to make some distance up so he's not going to have to travel quite as far.

Estimated time to firing range, 15 minutes.

Well then, the intercept on the time axis would be different for different curves.

So it would be the distance around.

Measure the distance between two points

Notice the same exact idea

Drag start time and Drag start distance

So on this day, she has to travel the same distance in time, well in both distance and time.

So what's d1? d1 is the distance between this point and this point minus f0.

But, let's look at things from Zeno's point of view and divide up the journey into pieces.

So that's 15 fewer km.. And so the number of km that Beth ran would be this distance right over here.

That was the closest we ever got... just 0.01 cm between us.

But let's take a look at the running time given that we can do this distance reduction operation in logarithmic time.

These two focal lengths are symmetric.

But I have a strong feeling he'll be there. ( ominous theme playing ) How far is it?

2200 feet.

How much further?

How far?
