If other stellar systems have planets that migrate , then ours must have too.
And there's a theory Jupiter and Saturn were closer to the sun and in resonance! At one time, the resonance sent Saturn further away while Jupiter hardly moved inward, thus preventing the Earth from getting too close to the Sun. Had Saturn been closer than Jupiter, the resonance would have sent Saturn much closer to the Sun and our planet would have been able to house life.
What the implication of migrating planets means is that life is even rarer than we thought.
Just one counter-example can completely change the way we understand the Universe.
Like Mars behavior in the sky, which made Copernic understand it turned around the Sun and not the Earth. Meaning the other planets also orbited the Sun and not the Earth.
Space/Science » in reply to re: I don't buy it. - A good college try and I concur.
Are we not strongly biased by our desire to find life out there?

- How effective is the search for planets like ours? Can they see them yet?
