The hunt for other planets that, like Earth, might be capable of sustaining human life continues - About one in 10 rocky planets around stars like our Sun may host a moon proportionally as large as Earth's, researchers say. Our Moon is disproportionately large - more than a quarter of Earth's diameter - a situation once thought to be rare. Using computer simulations of planet formation, researchers have now shown that the grand impacts that resulted in our Moon may in fact be common. The result may also help identify other planets that are hospitable to life. A report outlining the results will be published in Icarus. Last year, researchers from the University of Zurich's Institute of Theoretical Physics in Switzerland and Ryuja Morishima of the Laboratory for Atmospheric and Space Physics at the University of Colorado in the US undertook a series of simulations to look at the way planets form from gas and smaller chunks of rock called planetesimals. Our own moon is widely thought to have formed early in the Earth's history when a Mars-sized planet slammed into the Earth, resulting in a disc of molten material encircling the Earth which in time coalesced into the Moon as we know it. Link to full article - www.bbc.co.uk/news/science-environment-13609153If we were to discover another Earth-like planet, the problems associated with actually getting ourselves to it would remain. Would the discovery of such a home from home provide the necessary impetus to, more quickly, get us there? What do you think? |

I would love to go to another Earth-like planet, Royston. What crazy kinds of trees might they have there I wonder. Maybe trees that can walk?

Considering that there are billions of galaxies with billions of suns in our universe, chances are there are a lot of planets like Earth. Then as our universe popped out of a particle the size of a pin head, there is no reason to think there aren't billions more universes.
The idea of the meteor striking earth a glancing blow spraying matter in a ring around the planet doesn't take in consideration that the moon itself has been hit by some large objects and if it were just a mass of chunks would have shattered into pieces itself. Some of them could create a moon around our moon. But they didn't.
I prefer to think that the asteroid smacked right into a molten Earth and like the milk drop in the time lapse photos formed a perfect ball that got high enough to stay there with the milk drop crown and tip balls returning to Earth. The dusty surface is due to the constant bombardment since it was formed. Also that moon ball would have inherited the same rotation as Earth had at the time of the hit which may explain why we only see one side of it.
While our moon is important to the way our planet functions, it may not be essential to a different planet. Perhaps something else could do the job as well.

I would also agree.We have come to this idea like yourself Coldwarrior on debates like this thread.The numbers are so great that I would also believe even the possiblity of other humanoids. This also would give the impression IMO that this has perhaps always been for some time eons passed,way before the earth was formed. The templates of organic life are throughout the universe.

As I watched the mist rise off Mullett Lake in Michigan one summer morning, I wondered why it rose and clumped together into fluffy little clouds and floated away. What made the mist stick together into a cloud? It was equally disbursed across the surface of the lake to begin with. So began the idea of molecular attraction decades ago. This has been known for a long time for those familiar with Johanson Blocks (Jo blocks) that are used in measuring. They are made from a metal with a low coefficient of expansion from temperature rise and ground so finely that they stick together. It isn't magnetism or vacuum but molecular attraction.
If there was no attraction between the molecules of water, then there would be no clouds. The earth would be covered with a constant even mist.
Also the Earth at one time was a molten ball with a mixture of all the elements and compounds. Why did they come together in some places and not others. Various ores are present in some places and not others. They vary considerably in both weight and volume. Any heavier element should have sunk to the middle and stacked up accordingly like the skin layers of an onion. So we would have to dig deeper and deeper to mine heavier ores.
But that isn't what we have. The only way elements could have concentrated is while molten, they stuck together in the soup.
They did an experiment on one of the shuttle trips with some ground up dust in a bottle and discovered that the dust clumped after being shaken. To my knowledge, they didn't try another experiment of this nature with ground particles of many different compounds and elements. I think it would have been an "eureka" moment if they did.
What that means is there is another attractive force in the universe besides gravity. Maybe one of these Ph'D nuts who spend their time conjuring up another dozen of so dimensions of time and space could work on that rather than wasting the efforts on the useless.

But cw, often that working on the useless has produced things/ideas/concepts/etc. of vast importance.

When they start expounding on 11 dimensions and a universe that will expand into disintegration, that is pretty much useless effort. They should spend more time chewing the meat closer to the bone. They are just guessing and have no more validity than anyone else.

Even if they did, how'd we get there?-catapult?.....its best to assume they dont,and stop making a pigs ear of this one.................

Looking is a waste of resources, as its not likely to be accessible;the energy wud be better spent on contraception/compulsory sterilisation here on earth..........who wud get compulsorily sterilised?............anyone who contributes nothing............what do I mean by nothing?..............thats another conversation!

The news came from NASA scientists studying the results from the Kepler telescope which in its first two years in space has found evidence of more than 1,200 planets in orbit around far distant stars.
The early findings suggests that there are triple the number of known planets outside our own solar system - 54 of them are Earth size and in the habitable zones from their suns.
Only two potentially habitable planets have previously been found outside earth's solar system, so Kepler scientists are very excited at finding so many possible candidate planets.
Speaking at the American Association for the Advancement of Science, Kepler chief scientist William Borucki said: "I am really delighted that we are seeing so many candidate planets and that means there is a rich ocean of planets out there to explore.
"For every two stars we are seeing a candidate planet."

This has been a response to basic scientific research for centuries. Besides there is one vital reason to continue - we will outgrow earth's resources and need to expand to another planet. Do the research now and don't wait until it is imperative.

www.msnbc.msn.com/id/45554617/ns/technology_and_science-space/Here's one that looks promising .... "A 'major milestone' in search for Earth's twin NASA's Kepler telescope confirms first alien planet found in habitable zone" "The new finds bring the Kepler space telescope's total haul to 2,326 potential planets in its first 16 months of operation. These discoveries, if confirmed, would quadruple the current tally of worlds known to exist beyond our solar system, which recently topped 700." Rumor has it they have Pro Boards there with no moderators ....
