What do you suppose the odds are that another Earth-like planet exists somewhere in the Milky Way?

Question

One that is similar to ours in terms of a breathable atmosphere and temperature ranges that we as humans could tolerate.

Answer 1

Our planet could be just one in billions, like many grains of sand on a beach or the next galaxy could have thousands of earthlike planets. no one really knows.

Answer 2

Considering how massive the Milky Way is, I think it would be almost impossible for there not to be a planet like that. If you're really interested in science like that, I suggest you check out some of the astronomy books by the late Carl Sagan. Cosmos would be a great starting point, and it's available on DVD or VHS.

Answer 3

Odds are pretty good that there would be 2 earth like planets in the Milky Way Galaxy.

Answer 4

Oh you know it would be hard to put a figure to it, but I think the odds are fair, because the way the theory of evolution goes,it was all random events that lead to the evolution of this planet and the living beings on it,so if it could happen here it could happen else where else also,

Answer 5

life on different planets does not impact the easy existance/non-existance of God argument. i will gaurantee that somebody could element to a Biblical verse, that if taken in particular context, assuming particular translations are ultimate, could be taken to probably mean that God might have made life on different planets too. And on the comparable time, there remains no evidence of supernatural motives, on the same time as organic motives abound with evidence. If there replaced right into a 'writer' - he/she/curiously to have executed each little thing by using the ability that we are in a position to be conscious, and study greater approximately by using technology. If this writer holds us in charge for no longer believing in superstitious religious nonsense, then i does no longer choose to have something to do with it in the 1st place.

Answer 6

Let’s start...
Best stars are in the Main Sequence
These stars should not have companions
In an area distant enough from x-ray and gamma radiation
Since distance is a major factor from the star and within the galaxy
I'd say 1,048,576 Earth like planets

Answer 7

Ok, there are supposed to be about 100,000,000,000 stars in the Milky Way galaxy. Since we are working with a quadrant we’ll take 25 percent of those or about 25,000,000,000. Now that includes every star whether it is new, dying or whatever. Using what I call the Rule of Ten we can get an approximate number of stars with an Earth like planet and the number of planets with possible life.

Out of the 25,000,000,000 stars let’s figure that only 10 percent will be about the same age as our Sun. That would take the number down to 2,500,000,000. These stars would be yellow with about the same temperature and size and our star. This age would also give any debris surrounding the star to form into planets.

Of those 10 percent, or 2,500,000,000 would actually form planets. Now, we have 8 planets in our solar system. Most of the interstellar planets found by researchers have been determined to be the size of Jupiter and Saturn. This is just a guess going by the shift in the respective star when the planet orbits it. However, let’s use the Rule of Ten again and say that roughly 250,000,000 stars have planets the size of Earth and reduce it again by saying the ten percent of those stars have rocky type planets. So now we are down to 25,000,000 stars.

Now, the planet would have to be the right distance from its star. We are 93,000,000 miles from the Sun. That gives us just the right amount of sunlight, heat and radiation. Any closer and we’d burn, and farther away and we’d freeze. Out of those 25,000,000 ten percent would have planets in just the right orbit to sustain life. So, we now have 2,500,000 planets with a small chance.

Here comes the good stuff, lastly we have the planets where the right combination of lightening, chemicals and pure luck threw together a mix that grew, moved and became alive. Now, these would include everything to slime to bugs to intelligent creatures. So the Rule of Ten would knock the number of stars with any form of life in their system down to 250,000. If course, this would include planets like Mars whose life has come and gone.

Let’s do it one more time. Let’s say that only ten percent (25,000) of those life supporting planets have developed into multi-celled creatures, gained intelligence and became like us… for the most part. We now have 25,000 stars with planets orbiting them, supporting life and that life grew to at least post industrial revolution status. Not too bad of a neighborhood.

As of today their have been 166 stars with planets orbiting them. As I said these are the gas giants that are like those in our outer solar system. I am sure that with at least 25,000 possible civilizations out there someone we are looking at is looking back at us and using the Rule of Ten to figure out if we are here.

Sorry, probably way more than ya wanted to know. :^)

Short answer: About 25,000, give ot take.

Answer 8

As the universe has untold number of galaxies, the possibility of an earth like planet is likely.

Answer 9

of course there are many other planets like earth I dont think that god made this tremendous universe just for us

Answer 10

nope i dont think there any other planet out there like earth.
