Will Earth ever be rid of bad guys? Yes, because in the future there will be no life on Earth at all.
When all else fails, the sun will grow so hot as it ages the oceans and fresh water will dry up. Vegetation and all other lifeforms will cease to exist. Then the sun will grow and become a red giant, completely swallowing Mercury and Venus, and possibly Earth, but if not Earth, Earth would be too close for comfort from the sun’s surface.
At that point I suspect Earth will be completely void of all evil, rogue and repressive regimes and bad guys. In fact, it will be completely void of pretty much everything and look much like what Venus looks like today!
When we completely destroy our planet’s environment then and only then space conization would become our “main ideology.”
Sadly, however, even space colonization leads to the same question – will we destroy the next planet just like this one?
Not a variable star with fluctuating brightness, but our sun is getting brighter gradually over time. As the fuel in the sun is spent the sun gets 10% brighter and 10% hotter every billion years. So we estimate in a couple billion or so years the oceans will dry up and all life on Earth will cease. Earth will become much like Venus is now. Eventually the sun will turn into a red giant and expand to swallow Mercury, Venus and probably Earth.
Worry about the future of life itself on the only planet ever found to have life.
So you don’t have to worry about that rogue planet hitting us. You have to worry about the future of life itself on the only planet ever found to have life.
Am I a pessimist or a realist?
