A force known as orbital chaos may cause our Solar System to go haywire, leading to possible collision between Earth and Venus or Mars, according to a study released Wednesday.It is however 99% likely that all the inner planets will survive to be devoured by the Sun as it lycanthropically swells into a red giant and scorches the Earth down to its rocky crust, 5 billion years from now. Adjust your Outlook calendars accordingly.
The good news is that the likelihood of such a smash-up is small, around one-in-2500.
And even if the planets did careen into one another, it would not happen before another 3.5 billion years.
Representatives from Venus expressed their displeasure that the article's headline was "Earth-Venus smash-up possible in 3.5 billion years: study," completely omitting Mars's possible culpability.
... Of course, the nightmare scenario for life on Earth is a nearby supernova. I was imagining a disaster movie to that effect: gamma and x-rays suffuse the Earth, killing everyone in moments. Bit of a bummer. I'm not sure who survives for the last reel of the film. People in really deep mines or submarines?
Or, the universe could really be a vacuum fluctuation, after all.
