This is confirmed.
I don't think SpaceOddity was confused about the theory of evolution...

And no, it hasn't been confirmed / considered scientific law like Newton's universal gravity. Bacteria micro-evolve by trading plasmids and by reproducing in numbers and frequency magnitudes larger than what we're used to, but that's a whole other story than evolution in higher organisms.

Humans are the only creatures that adapt their environment to suit their life...
+ =

But for the most part you're correct. Did the evolution of the camel's hump decimate ancient African forests, turning them into deserts?  ::)

I'd rather my planet's environment changed and I had to adapt to it by, in an ice age, adding fur and changing to a mouth that could scrape nutrients from the tundra in the case of a herbivore; or, as the poles bagan to melt, becoming able to swim and changing my mouth to a long fish-catcher in the case of a carnivore (in the expansion  ;) ); etc.

Personally I wouldn't have a problem starting on a wierd planet and not "just another" Earth. After a while it would grow on me and become mine as I added to it, which is the whole point.

I managed to crash a huge gas giant into the Sun on my first try and for my second I tried making something in the Inner Solar System that ended up wiping out Mars. Oops...



Your mission, if you choose to accept it, is to scour the Internet for applications like this that allow interactive modeling of the Solar System (not just tours) and modification of orbits using simulated physics.

Your monitor will self-destruct in 10 seconds...

Again, "Hot Jupiter" systems were thought to be mostly devoid of objects as the gas giant's orbit migrated, plowing into everything like a bowling ball knocking down pins. The computer modeling in the study suggests there's a good chance for worlds and even Earth-like planets to form in the wake of that migration.

The article does mention projects like the Terrestrial Planet Finder, and that it will have even more targets to scout. :)

The illustration is about the planets the article describes, how is it a twist? I figured it was relevant to Spore to begin with; its all there in the article, I didn't 'add' anything.

If astronomers do find extrasolar Earth-like water-worlds in "Hot Jupiter" star systems like the study predicts, it would make it that much more important to have an aquatic phase (either at release or in an expansion).

Earth-like planets may be more common than once thought, says new U. of Colorado-Penn State study

More than one-third of the giant planet systems recently detected outside Earth's solar system may harbor Earth-like planets, many covered in deep oceans with potential for life, according to a new study led by the University of Colorado at Boulder and Pennsylvania State University.

The study focuses on a type of planetary system unlike our solar system that contains gas giants known as "Hot Jupiters" orbiting extremely close to their parent stars -- even closer than Mercury to our sun, said CU-Boulder researcher Sean Raymond. Such gas giants are believed to have migrated inward toward their parent stars as the planetary systems were forming, disrupting the space environment and triggering the formation of ocean-covered, Earth-like planets in a "habitable zone" conducive to the evolution of life, according to the new study.

"Exotic Earths: Forming Habitable Worlds with Giant Planet Migration" was published in the Sept. 8 issue of Science and authored by Raymond, Avi Mandell of both Penn State and Goddard Space Flight Center in Greenbelt, Md., and Steinn Sigurdsonn of NASA's Goddard Center.

The study indicates Hot Jupiters push and pull proto-planetary disk material during their journeys, flinging rocky debris outward where it is likely to coalesce into Earth-like planets, said Raymond. At the same time, turbulent forces from the dense surrounding gas slow down the orbits of small, icy bodies in the outer reaches of the disk, causing them to spiral inward and deliver water to the fledgling planets. Such planets may eventually host oceans several miles deep, according to the study.

"These gas giants cause quite a ruckus," said Raymond of CU-Boulder's Laboratory for Atmospheric and Space Physics. "We now think there is a new class of ocean-covered, and possibly habitable, planets in solar systems unlike our own."

Scientists had previously assumed that as Hot Jupiters plowed through proto-planetary material on their inward migrations toward parent stars, all the surrounding material would be "vacuumed up" or ejected from the system, he said. "The new models indicate these early ideas were probably wrong," said Raymond.

The research team ran exhaustive simulations lasting more than eight months each on more than a dozen desktop computers, starting with proto-planetary disks containing more than 1,000 moon-sized, rocky and icy bodies. The initial conditions for each computer model were based on current theories of how planets form in our own solar system and simulated about 200 million years of planetary evolution.

The team concluded that about one of every three known planetary systems could have evolved as-yet-undetected Earth-like planets in so-called habitable zones like the one Earth is in, he said. A whopping 40 percent of the 200 or so known planets around other stars are Hot Jupiters, although the percentage probably will decrease as more distant planets are discovered, said Raymond.

In addition to Earth-like planets that form in habitable zones outside Hot Jupiters, the simulations showed some rocky planets known as "Hot Earths" often form inside the orbits of Hot Jupiters, said Raymond. A Hot Earth, with a radius twice that of our own Earth, was discovered in 2005 in a nearby star system orbiting just 2 million miles from its parent star by a team led by University of California, Berkeley, planetary scientist Geoffrey Marcy.

The new simulations showed both Hot Earths and Earth-like planets in habitable zones formed with large amounts of water, up to 100 times the water present on Earth today, he said. The models indicate such water-rich planets would probably contain a lower percentage of iron - which may be important for the evolution and possible oxygenation of evolving atmospheres - than Earth, he said.

According to the team's simulations, Hot Earths can form astoundingly fast, in just 100,000 years or so. Earth-like planets in habitable zones form much more slowly, taking up to 200 million years, said Raymond. Geologists believe Earth took about 30 million years to 50 million years to fully form.

"I think there are definitely habitable planets out there," said Raymond. "But any life on these planets could be very different from ours. There are a lot of evolutionary steps in between the formation of such planets in other systems and the presence of life forms looking back at us."

The new research effort may allow planet hunters to determine "rough limits" indicating where to search for habitable planets in known systems of giant planets, according to the team, whose research was funded by NASA's Astrobiology Institute headquartered at the NASA Ames Research Center in Moffett Field, Calif.

"Upcoming space missions such as NASA's Kepler and Terrestrial Planet finder and ESA's COROT and Darwin will discover and eventually characterize Earth-like planets around other stars," wrote the authors in Science. ""We predict that a significant fraction of systems with close-in giant planets will be found to have a Hot Earth or potentially habitable, water-rich planets on stable orbits in the Habitable Zone."

Black hole gun

http://www.exitmundi.nl/blackholes_lab.htm


Or, as a way to "de-civilization" a planet, a gun that shoots nanomachines at people. I realize this is off-topic, sorry. In a matter of a few moments, the nano-machines travel to the brain and eat it, recording information and building a data storage device as they go. What's left is a wad of grey goo (self-inactivated nanomachines) and a fist-sized crystal which contains everything that the individual was, mentally. Erase the last few seconds from memory, up-load this onto a mainframe, and let them continue to believe they are the masters of their planet.

That "discussion over" thing is really pretentious. Who do you think you are?

SpecialBrownies: I discount your counter-argument on the basis that I could have probably thought up a better reply.

Doesn't sound like a good way to debate, now does it? I could have used any example, mine was personal.

AKA Over-speculation is bad for your health

I'd like to share a little story with you. Years ago I lurked the Fable forum much as I do this Spore forum. I specifically remember this one discussion pertaining to how the game was going to deal with the player's death, going on the following premise: Moleneux had mentioned really hard games like Ninja Gaiden and said they'd never want to punish the player the way they do. One poster assumed this meant that when you 'died' you'd wake up back in town after being drug back by a towns person.

One day I in Fable I decided to die and see what happened. I attacked a group of bandits, put down my controler, watched as my 9 auto-ressurrect potions were used, and saw...












A game over screen. :-\ Nothing different than what happens when you die in Ninja Gaiden. Was it my fault for expecting something cool and never seeing it in game? Yes.


My point is this: I like to get worked up about a game before its released the same as the next gamer, but there's excitement and fanboy-ism... and then there's the flamefests based on scraps on vague information that have seemingly invaded this forum.

So please, calm down and remember Spore isn't complete and don't know what the finished product will be.

Thank you.

I have nearly every book. Spore reminds me a lot of the 'Galactic Civilizations' game they played. I hope no real aliens see YouTube videos of us doing Bad Things in Spore: they'd think we were galactic overlords and come to wipe us out! ;)

Its hard to not be land animal -centric and Earth-centric about the development of technological civilization. I find it difficult to see the leap from something similar to dolphins or squids (or any other "smart" underwater organism) to domed, flooded colonies (with structures made of metal, plastic, and glass) on an alien planet. (Although thinking about it again, they'd colonize the oceans, so their idea of a good planet for colonization would be differet from ours. Not by much though, we'd both be looking for liquid water.)

The aliens in The Abyss came from a planet with similar conditions as the bottom of our oceans - cold, dark, and intense pressure. I wonder how they did it...

Or even stellar environment. In The Ellimist Chronicles the main character's civilization invented something that ended up being superior to radio waves because the background radiation/interference from the close-by galactic core was too intense.

Maybe if one or both planets were slightly off the ecliptic plane and their orbits synched, one could occupy the same distance from the star as its sister planet without ever being in the same place at the same time.

General Relativity states that gravity is the curvature of space-time caused by mass, any other bodies then follow this curvature as it is the path requiring the least energy (Aslong as no greater force is acting on it). To illustrate this, if you stretched out a sheet out and dropped a heavy ball into the middle of it, it would then create a depression in the sheet, down which any smaller balls would roll. Also, if you flung the ball with enough force it could then overcome the depression. So when planets are obiting a sun, their momentum carries them around the edge of this depression in space-time.

This therefore does not make it impossible to have two planets occupying the same orbit. If their speeds were equal and the orbit was large enough that the effects of gravity between the planets occupieing were neglible then it could even last. It is extreamly unlikely, but not impossible.
They were talking about planets in contradictory orbits (one traveling counterclockwise, the other clockwise). Can't see it happening naturally.
