They would be able to push space forward.

The Alcubierre warp drive, for example, could be found.

All those kinds of things.

We could make wormholes.

That is another possibility.

But we don't see them.

We haven't seen a single wormhole.

We haven't seen a single white hole.

So the existence of those things has not yet been confirmed and appears to be contradicted or refuted by the fact that we don't see these things.

That phantom energy is not what dark energy actually is.

But that's just the opposite of in math.

Yeah, I have no idea, but I'll tell you something else that's been really interesting.

Maybe we can save this for later in the show if there are other questions regarding this.

But I was at the American Astronomical Society meeting not too long ago in Phoenix.

And I was just so happy.

There was just a lovely time.

I'm still basking in it, even though it's been a little while.

But one of the last speeches, one of the last talks in that conference was about the nature of dark energy.

The dark energy survey, which has now gathered information about 15 million galaxies and where they're placed in the universe, seems to show that what we have counted as dark energy, the cosmological constant,

is probably not constant.
