I think the fate of the world is always in our hands. We can just need to see the possibilities.

I think the future depends on our imagination. Can we see the opportunities? Take the explosions on Mars for example: I think aliens are headed this way.

If I am right, then we need to act to save the world. And maybe we can learn from their technology!
And if I'm wrong? Then we should still think of how space travel might work, so we can explore other planets. Think what we might discover!
But wait, I haven't introduced myself. And I haven't explained why this is 1900 when maybe you were expecting 1894. Or should I stop talking and watch the skies for aliens? Or do something else?
