Could 'Goldilocks' planet be just right for life?
Associated Press ^ | Wed Sep 29, 7:19 pm ET | By SETH BORENSTEIN, AP Science Writer Seth Borenstein, Ap Science Writer

WASHINGTON – Astronomers say they have for the first time spotted a planet beyond our own in what is sometimes called the Goldilocks zone for life: Not too hot, not too cold. Juuuust right.

Not too far from its star, not too close. So it could contain liquid water. The planet itself is neither too big nor too small for the proper surface, gravity and atmosphere.

It's just right. Just like Earth.

"This really is the first Goldilocks planet," said co-discoverer R. Paul Butler of the Carnegie Institution of Washington.

I'm torn between going there myself, or stuffing it full of liberals and hitting the launch button.........

"But know this, that in the last days perilous times will come: for men will be lovers of themselves, lovers of money, boasters, proud, blasphemers, disobedient to parents, unthankful, unholy, unloving, unforgiving, slanderers, without self-control, brutal, despisers of good, traitors, headstrong, haughty, lovers of pleasure rather than lovers of God, having a form of godliness but denying its power. And from such people turn away, for his name is Obama."

Countless parameters have to be “just right” to sustain complex life. Not just 3 or 4 or 100.

Gee, I guess they didn't mention the part about the planet being tidally locked which means all the atmosphere is permanently frozen on the permanently dark side.

Earth-like my a$$.

You can't go the speed of light - Einstein's relativity theory forbids it.

But a little known fact is that nothing in relativity theory forbids going faster than the speed of light.

Which is like, handy.

probably more reasonable to suggest we can travel 1/10 the speed of light — thus 200 years. Still reachable. However this planet is locked facing its sun so the likely potentially habitable area is a narrow band around its equator — thus much of the planet would be inhabitable.

Too many ‘coulds’ and ‘possibly’s’ and ‘might’s’ and ‘in theory’s’ for me. Total speculation on so many if’s, it’s hard to believe this isn’t listed under Science Fiction.

We have a planet like that. It’s called Earth. No other one like it. Not yet.

If we knew we could live there, I’d say let’s go, but since we don’t, just send the libs there instead. They’re the ones who always whine about the planet, let them see another planet and realize just how good this one is.

Okay, let’s get special relativity right: in the vacuum, massless particles (like light) travel at the speed of light; massive particles (or macroscopic objects made of such) cannot be accelerated to the speed of light due to the Lorentz shift in mass, which would mean an infinite amount of energy would be needed to accelerate them to the speed of light.

As to superluminal travel, in the sense of ordinary motion through space, it is forbidden by special relativity.

What is not forbidden by the theory are dodges like warp drives and stable wormholes. In fact there are solutions to Einstein’s equations (general relativity) which allow both—one solution is called “the Alcubier warp drive” because a body in one region of space-time in that solution looks like a warp-driven starship to the rest of the universe.

Unfortunately, all of these exotic solutions require there to be regions of space-time with negative mass-energy density. Negative energy densities have been observed, but only at the level of quantum fluctuations in the presence of equal nearby positive energy densities (if they tunneled out of the vacuum, or larger positive energy densities if some process was used to create a negative energy density).

There seems to be no way to collect lots of negative energy in one place to make either a warp drive or a stable wormhole. (Incidentally the amount of negative mass-energy
needed to make a wormhole big enough to walk through and keep it open is about minus the mass of Jupiter. I’m not sure the estimates on the Alcubier warp drive.)

It's been estimated that there are more stars in the known universe than all the grains of sand, on every beach on earth.

With numbers that staggering, I'd say the odds of the "primordial soup" occurring in places other than Earth are very good. In fact, I'd say that it's a certainty.

Exactly! “Tidally locked” means it is a dead planet for all intents and purposes. It is of my opinion that a planet’s rotation is just as important to sustaining life as being in the “Goldilocks” zone. They must be getting short on grant money.

Maybe you should ask ol' unck Joe or any other dawinist about the chances of it happening twice. Or what the mathematical chances of it happening once.

I have trouble with this, too. If a planet is tidally locked, it would get searing hot at the point that has the most direct sun, and freezing cold on the back. Although atmospheric winds would moderate this somewhat, I can’t see a situation where life would take hold without any sort of day-night cycle or where the sun never moves in the sky.
