Question What would the human race be like if we lived on a different Planet, Galaxy or Universe.

It will depend on whether there are bad zip codes. According to modern academic research, your future and your life is determined by the zip code you are born and raised in. This is verified by tracking lives for the last two hundred years. There is nothing one can do about it. The research proves this to be true. The obvious answer is to only give birth in good zip codes. Modern science will show us the way. Easy Peasy. We don't need a new planet, just good zip codes. If you pay attention to the research, the answers are easy.

Well, there is serious catch to "living somewhere else besides the earth", for a planet has to have an atmosphere that has the precise proportion of oxygen (21 percent of the atmosphere for humans, animals and other organisms to breathe as the Hebrew word nephesh designates that literally means "breather" at Genesis 2 in the Bible) to nitrogen (78 percent of the atmosphere for plants to grow by means of a nitrogen cycle through certain bacteria, in which if there is none, root systems and plant growth is stunted, causing photosynthesis to cease) to carbon dioxide (about 0.4 percent for plants to extract the carbon) to begin with.

Plus, a planet has to be just the right distance from the sun (in which our earth is 93 million miles from the sun), so that temperatures are within "a comfort zone" that produces neither extreme freezing nor extreme heat, and whereby if the earth were just 5 percent closer to the sun, we would "roast" while just 1 percent farther away, we would "freeze". Planetary scientist Andrew Ingersoll said that "Mars is too cold (average temperature is -81 degrees F.), Venus is too hot (with a surface of over 900 degrees F., easily hot enough to melt lead, which melts at 621.5 degrees F.), Earth is just right".

In conjunction with this is the fact that a planet has to be just the right size, for too small, gravity would cause a loss of surface water and oxygen, being too weak to retain it or too large, gravity would cause hydrogen to be held to ground level (that would eventually cause all life to die due to an excessive buildup) instead of being released away from the planet and kept in exact proportion to other gases that exists on the earth, being among the 0.6 percent of gases that completes the whole number of gases necessary for life and the exacting force of gravity keeps all life on the ground instead of slowly floating away, and in which the moon is an example of a much weaker gravity that has no atmosphere.

In addition, a planet has to have a magnetosphere, that produces an invisible "force field" of particles around it so to protect it from a star's steady deadly particle showers or cosmic radiation, also called "the solar wind". According to Daniel Lathrop of the University of Maryland that teaches physics, that if the earth had no magnetosphere, life could not exist on it due to the destructive effects of "the solar wind".

There is many more requirements for a planet to be able to "carry" life on its "back". In reality, only the earth has all the necessary requirements for life to exist and "be happy". Just as a home that has excellent environmental controls that keeps its comfortable for its living inhabitants, requiring a mind to construct, so likewise the earth is not an "accident", but is an intentional act of a Supreme Designer, whose personal name is Jehovah.(Ps 83:18 in the Bible, KJV)
Read some Stephen Baxter, where some far future 'humans' live in the corona of the sun. Or RAFT, where humans stumble into a galaxy where gravity equals orders of magintude more...and so on.....

SF....before this decade at least, and by those over 40.....has thought all this stuff out, yo.
