Will the habitable zone of earth come to an end? On Sept. 23, MSN News reported that scientists believe that there is only about 1.75 billion to 3.25 billion years left to thrive. While that is really a "forever" in and off itself, it's actually something that scientists have been looking into and trying to figure out.
"A planet is considered to be in the habitable zone when liquid water can exist on its surface. If Earth was too close to the sun, high temperatures would cause our oceans to evaporate; too far away, and we'd be an icy wasteland," MSN News reported.
The habitable zone on earth could be depleted thanks to a giant asteroid or a nuclear war but, in theory, the earth has billions of years left and many things could change the outcome of earth's life. As with everything in the solar system, the earth is ever-changing and evolving each second that passes. So, if life won't be able to survive on earth in 3.25 billion years, what will become of the planet you live on?
"Instead of being in the habitable zone, Earth will be in what astronomers call the hot zone. Oceans, liquid water and life will cease to exist on the planet," MSN News reports.
Is the habitable zone on earth something you think about? Do you think that life on earth is infinite?
