Earth's Final Sunset Predicted

Posted February 26, 2008 9:00 AM

From Yahoo! News: Science News:

"Some say the world will end in fire, Some say in ice," wrote the poet Robert Frost. Astronomers, it turns out, are in the former camp. A new calculation predicts that Earth will be swallowed up by the sun in 7.6 billion years, capping off a longstanding debate over whether the sun's gravitational pull will have weakened enough for Earth to escape final destruction or not.

That is an awful long time to wait, so why are we talking about this event now?

For a start, what makes people think that humans will be around to experience it?

I believe that humans will be long gone by the time this event happens, we have either died out or we have colonised a new planet. Lets face it, the history of human habitation on this planet is a very short one in terms of the history of our solar system or the universe as a whole!

The Moon presents the same face to the Earth, i.e. for any stationary observer on the Moon, Earthrise has stopped. The cause is tidal locking.

Now, the day length on Earth is increasing over time. So eventually the Earth will present the same face to the Sun. The cause will also be tidal locking.

So the question now is, will Sunrise stop before the expanding Sun swallows it or not?
