Could we be unique in the universe or is there another planet similar to earth somewhere in the cosmos? Is it possible that Alpha Centauri, our nearest star, is home to another earth-like planet? Earth sized planets have been hard to find, but indirect methods are coming on line to give scientists a good survey of how many such bodies may be in the universe. How rare would it be to find life on another earth-like planet?

Id hardly say rare. There are expected to be 2,000,000,000 earth like planets in the Milky Way alone.

Il have a watch of this later, got some decorating to do

We've already found an earth-like planet. It's called Mars.

In what ways are mars and earth similar? apart from the obvious superficial things like they are both round
Mars is a dead frozen wasteland devoid of life, while the earth is a life-support system rich in biodiversity. The two worlds may have been very similar billions of years ago, but they are very different now.

The problem with mars isn't the low pressure atmosphere, its the lack of a significant magnetic field that would protect the atmosphere. If mars rotated faster then the interaction between the suns magnetic field and Mars would cause Mars' magnetic field to increase thus preserving the atmosphere. Either that or bring Mars closer to the sun where the suns magnetic field is stronger. I don't personally know how to do either.
It works in much the same way as a generator where as the rotation of a ferromagnetic material within a magnetic field produces a magnetic field within the ferromagnetic material and causing current to flow which in turn produces heat which will cause the core temp to rise which will release more gas from subterranean pockets which will enter the atmosphere where it is protected by the newly introduced magnetic field. Maybe.

Venus is more Earth-like than Mars. They are finding Earth-like planets that they are predicting can have up to 50% cloud cover, water clouds that is. Water, clouds, lightening, and dirt is all you need for life.

What are you guys going on about... its about exoplanets outside our solar system.. try and watch the documentary instead...

The strength of our magneticsphere is based on the speed of a planets rotation? Hadn't heard that before

makes me think about the saying "money makes the world go around."
And then think about how the dollar is the base currency.
And how the dollar is crumbling.
How the dollar and money in general is a talisman for the occult to control energy flow.
And then how why we are seeing the magneticsphere weaken to some degree.

Damn it I'm dreaming again... or am I? ITS ALL TO REAL AND UNREAL FOR ME TO MAKE LOGISTICAL SENSE OF NOOOOOOOO!!

More precisely its based on several factors such as proximity to the Sun, speed of orbit around the sun, speed of rotation within the Sun's magnetosphere, conductivity of elemental composition, strength of core reaction, heat produced, heat dissapated, etc, etc.... Its a pretty complex thing to produce a magnetosphere.

If its so like earth why are people not living there. You are spouting :-# !

Both Venus and Mars share the problem of a breathable atmosphere. I don't like wearing a respirator anyhow so I would not like to visit.

Earth's atmosphere comtains...
78.08% nitrogen (N2)[3]
20.95% oxygen (O2)
0.93% argon
0.038% carbon dioxide
About 1% water vapor (average)

Venus atmosphere comtains...
~96.5% carbon dioxide
~3.5% nitrogen
0.015% sulfur dioxide
0.007% argon
0.002% water vapor
0.001 7% carbon monoxide
0.001 2% helium
0.000 7% neon
trace carbonyl sulfide
trace hydrogen chloride
trace hydrogen fluoride

Mars atmosphere comtains...
95.32% carbon dioxide
2.7% nitrogen
1.6% argon
0.13% oxygen
0.08% carbon monoxide
210 ppm water vapor
100 ppm nitric oxide
15 ppm molecular hydrogen[10]
2.5 ppm neon
850 ppb HDO
300 ppb krypton
130 ppb formaldehyde
80 ppb xenon
30 ppb ozone
18 ppb hydrogen peroxide[11]
10 ppb methane[12]
