So, we're really getting somewhere now.
Now that these things actually are planets because we can measure the radius and, not only do they have gas giant masses,
but they actually have the radii of gas giants, they really must be planets.
Well, yes, but they are a little bigger than they should be, aren't they?
They're quite a bit bigger than Jupiter, for example, and we don't really understand that,
and we don't really understand how they got there in the first place.
Yes, and we have talked about a couple of theories, the migration one, which was looking good for a while,
but the fact that some of them seem to be going backwards seems to imply that, actually, the Billiards theory is a better one for these things.
Right, okay so we still have a few mysteries here to solve, and these gas giants are interesting,
but I kind of want to know about normal planets. Planets that might have life.
Nice and smaller ones.
Yes, I'd like to find some smaller ones, I kind of would like to know more about the planets,
rather than just say "yeah, it's about a planet that's sort of looks like Jupiter".
It would be nice to find some ones that are further out, I mean, these things are all very close to the star and probably too hot.
It's nice to find some ones that are actually out where big planets are supposed to be, like in our own solar system.
That's right, so, presumably, we're going to have to rethink a little bit of how we find these objects.
I mean, we've got the basic idea here, but it doesn't seem to quite be delivering what we really want.
