We are here.

And we want to go there.

Figuring out how to get there

The first step in getting from here to there is knowing where there isn't.

I suppose a good place to start is checking to see if here and there are in fact the same place.

Are we there?

Nope.

Well, let's say we want to go there from here (because we do).. Which way do we have to go?

I think we can do that. How far will we have to travel?

Great!

Getting there

So, we know where we are, we know where we aren't, and we know the distance and direction we'll have to travel. What's next?

Unfortunately, as the answer tends to be, physics is next.

We can't exactly just go there. We have to get there. And that means we have to spend some time 'twixt here and there.
