So let me get this straight:
1.) we have discovered another, Earth-like planet, potentially capable of supporting life;
2.) it orbits a red sun;
3.) it’s a larger planet, and the gravity there is stronger than it is here;
4.) it is twenty light years away, so it could have exploded nineteen years ago and we would only know about it next year.
Clearly, we must watch the skies for incoming escape pods. Alert Kansas!
(Oh, come on, you thought of it too.)
