For every star is their an Earth? If so how many worlds are their?

Answer 1

I knew the answer but is not enough space in page to wrote it.
an infinity of worlds

Answer 2

As many people have pointed out, the components needed to produce another earth-like planet are both numerous and complex but since there are trillions of stars, it is almost certain that other planets similar to ours exist. But I would also like to add another twist to the story.

For as long as man has lived on this planet, we have always considered ourselves to be at the centre of everything. We used to (and some people still do) believe that the earth was created in seven days. Then when other planets were discovered, we decided that we were the centre of the solar system and indeed the universe. We now know that this is, of course, also not true. If we only think along these lines, we will fail to see the other posibilities that could exist. Why must a planet with life as advanced as ours have to be the same as ours? If I said to you " How would you like to live on a planet whose atmosphere is 95% nitrogen,has a gravitational force of 4 times this planet, and has a temperature that never gets any higher than minus 150 degees celcius?" I think I would know your answer! But what if plantlife existed when this imaginary planet was formed? Why couldn't this gradually evolve over millions of years to develop a form of intellegent life similar to our own or even more advanced?

You only need to look at our own planet to see different forms of evolution. If you take a fish out of water, it dies. Put a human being under water without any artificial breathing aid, he dies. I accept that this is a slightly different case since both fish and man breathe the same gases, but it shows that if things are allowed to evolve over millions they can live in entirely different life forms.

This now opens up a whole new line of thought and considerably increases the possibility of intellegent life out there!

....just a thought.

Answer 3

It's certainly a possibility that there are many Earth-like planets in the Universe. The following is the Drake Equation...

Is there a way to estimate the number of technologically advanced civilizations that might exist in our Galaxy? While working at the National Radio Astronomy Observatory in Green Bank, West Virginia, Dr. Frank Drake conceived a means to mathematically estimate the number of worlds that might harbor beings with technology sufficient to communicate across the vast gulfs of interstellar space. The Drake Equation, as it came to be known, was formulated in 1961 and is generally accepted by the scientific community.


N = R* fp ne fl fi fc L

where,

N = The number of communicative civilizations
R* = The rate of formation of suitable stars (stars such as our Sun)
fp = The fraction of those stars with planets. (Current evidence indicates that planetary systems may be common for stars like the Sun.)
ne = The number of Earth-like worlds per planetary system
fl = The fraction of those Earth-like planets where life actually develops
fi = The fraction of life sites where intelligence develops
fc = The fraction of communicative planets (those on which electromagnetic communications technology develops)
L = The "lifetime" of communicating civilizations

Frank Drake's own current solution to the Drake Equation estimates 10,000 communicative civilizations in the Milky Way. Dr. Drake, who serves on the SETI League's advisory board, has personally endorsed SETI's planned all-sky survey.

Answer 4

The list of conditions for an Earth-like planet to exist is very long. A very small percentage of stars will have Earth-like planets, but there are almost unimaginable numbers of stars, so there should be many similar planets to Earth.

Answer 5

It is implausible and arrogant of mankind to believe that there is no other planet in the universe that contains intelligent life.

The conditions needed to create and sustain life are huge and varied, granted, but the kinds of lifeforms on this planet alone are just as vast. We, the planet Earth, are just an insignificant dot on the landscape of the galaxy, let alone the universe.

Answer 6

Not every sun has an earth. but many of them do. and some may have life forms.

Answer 7

No htere isn't more than one earth! And if there were there would be millions and billions. There are as many stars as grains of sand!

Answer 8

There are all kinds of starts that may or may not have all kinds of objects orbiting them. Given all the stuff in the universe, it is inevitable that there are other planets like earth.

Answer 9

Every star does not have a solar system (planets orbiting it).

Answer 10

nope - only 1 Earth around SOL
