As the post’s author says:
Almost every month there is a new prediction by someone for the end of the world. For the last 5,000 years (since we’ve been keeping track of doomsday predictions), every prediction has been wrong. Odds are pretty good that this prediction will be wrong, too.
My view is that, barring a world-shattering collision with a monster asteroid or other astral body, the Earth will be around for a long, long time. Probably until the Sun runs out of hydrogen and begins to die, during which process its atmosphere will expand as its core collapses and it turns into a red giant that will engulf the Earth. That won’t happen for another 4 or 5 billion years by which time, let’s face it, the human race will be long gone – most likely wiped out by our own actions.
