Alright so i just had an interesting thought. If a human baby was born on mars or any other planet for that matter would humans on earth consider it an alien or not? Reason why i thought of this is because what if there are aliens on different planets similar to earth and they are almost completely identical to us what would be the difference between that baby and the alien? <br /><br />My second question is about the speed of light or getting close to it. I read online that nothing can travel the speed of light or faster then the speed of light. So if we had a spaceship capable of traveling at 99% the speed of light how would we control the damn machine? I would think at some point it would just slam head on into a planet.<br /><br />Anyone can help explain my questions? When i get random/weird ideas like this i hate having no answers especially when you search Google for an hour or so and find no answers. Thanks a lot i appreciate it.
