65 million years ago, the Sun stopped being a red giant

[epigeios]

I'm fairly new to EU in general, but have been reading fairly heavily about it and related subjects for the past week.

Most recently, I read both Twinkle, twinkle electric star and SETI – The Search for Extraterrestrial Intelligence.
The idea that the Sun was a red giant until 65 million years ago came to my mind. I searched for anyone who might have had a similar idea, but didn't find anything.
From what I understand, this would allow Earth to have been a global tropic zone with far more energy input than there is today.
This would make cold-blooded animals far more efficient than warm-blooded animals. Warm-blooded animals would be pretty much limited to the niche of hiding in rare cold areas.
This would also explain a global extinction of giant cold-blooded animals, and why the warm-blooded animals had a diverse enough spectrum of species to bloom into the species found today. This would also imply that the majority of the major evolutionary changes of mammals happened before the mass extinction, but that each family or genus might have been limited to only a few species instead of the tens or hundreds we see today.
This would especially account for the overall much larger trees, and other flora, thought to have existed at that time.
And I think I remember something about cold-blooded animals not being limited to size like warm-blooded animals are, but I wasn't able to find anything relating to that with a cursory search.

So, given that this might make sense, I have a few questions. Specifically, what would happen to Earth in general if the Sun reduced from a red giant to a regular star? And is it necessary that something triggered this?
I imagine it wouldn't be a slow reduction in size, but more of a dispersal of the outer layer. Would there be a heavy electrical change in the solar system?
If it is indeed necessary that something triggered this, would the capturing of Uranus from the Milky Way, or anything else involving the introduction of the Sagitarius Dwarf galaxy to the Milky Way be sufficient in causing the change?

On a side note, is it accepted yet that Uranus is from the Milky Way, or am I reading too far ahead?

* The Milky Way is our galaxy of several 100 billion stars. I think you meant to say Solar System, not Milky Way.
* The evidence amassed by Cardona, Talbott, Thornhill and others leads them to suppose that Earth, Mars & Venus were moons of Saturn a few thousand years ago and Saturn was a brown-dwarf star, which slowly entered the Solar System and then lost its largest moons here, which became planets of the Sun. The evidence hasn't yet been able to tell them, I don't think, if any of the other gas giant planets were part of the Saturn System, or what. Jupiter seems to have caused the disruption of the system.
* I don't think they have speculated on what the Sun may have been in the past. They don't consider conventional dating at all accurate. Thornhill, Scott et al consider that a star's size and color only indicate how strong the electric current is that lights up the stars. When Saturn entered the Solar System, the Sun stole some of its current, making Saturn dimmer than it used to be. Anyway, the Earth has been in the Solar System only for a few thousand years now, apparently.

that was impossibel

[Lloyd]

* It's impossible for Earth to have been a moon of Saturn?
* Why is it impossible?
* Or do you mean it's impossible that Saturn was a brown dwarf star outside of the Solar System?
* And why is that impossible?
