Earth-Like Planet Found

It's always possible. There's a chance that Earth contains at least one atom of every type of element (most of which we haven't discovered yet) and there's an even higher chance that there's more in the universe that we had no idea existed. Who knows? The laws of physics can even be broken elsewhere in the universe. xP

iirc isnt already the accepted norm that the laws of physics that we know of only apply to our solar system/galaxy? all of this is of course a theory, though.
