Is it possible for aliens millions light years away to see dinosaurs on Earth?
- mcappleton 9y agoThat was hilarious, thanks for sharing.
- xparadigm 9y agoWhat if aliens use some other kind of telescopes? What if these aliens had no Galileo Galilei in their history and thus developed a very different kind of telescope say, the kind that uses gravitational lensing for optics?
