Thread: Galaxy has 'billions of Earths'
#1 Galaxy has 'billions of Earths'02-21-2009, 05:50 PM
There could be one hundred billion Earth-like planets in our galaxy, a US conference has heard.
So far, telescopes have been able to detect just over 300 planets outside our Solar System.
Very few of these would be capable of supporting life, however. Most are gas giants like our Jupiter, and many orbit so close to their parent stars that any microbes would have to survive roasting temperatures.
So where are these 'billons of earths'? No one knows because they haven't found any yet. They are basing their hypothesis on conjecture nothing more."If every poor man is to come here and start requesting money for all his children, the applicants will never be satisfied and the nation's finances will collapse."

Why would there be so many planets that could not support life. And who is to say it doesn't support a life of some sort? Seems like a big waste of planets.

The number of planets we can see are only the tiniest fraction of a percent of what's out there. Just because we haven't seen any yet, doesn't mean that they aren't there. Our current technology doesn't allow us to see much detail of any kind in nearby stars.Education is what remains after one has forgotten what one has learned in school.

I think it is highly likely that there is life somewhere in the universe. Heck, they found those fossilized bacteria on Mars! Also, who is to say that there is no life on planets that are hot? We only know of life on earth, maybe other creatures live in more extreme climates. Maybe they don't need water or Oxygen. All we can do is guess, but I cannot fathom that out of the huge infinite space of the universe Earth is the only planet with any life."Government's first duty is to protect the people, not run their lives."
Life is a story; if you stay on the same page forever you will never finish it.

I just find it hard to believe that the good lord created all this (the galaxy...universe as a whole) and then made one tiny (relatively speaking that is) planet to put life as we know it on. Then again thats just my opinion.“The characteristic of genuine heroism is its persistency. All men have wandering impulses, fits and starts of generosity. But when you have resolved to be great, abide by yourself, and do not weakly try to reconcile yourself with the world. The heroic cannot be the common, nor the common the heroic.”
