Mad For Science Posted February 18, 2015 Share Posted February 18, 2015 (edited) I don't know if this question belongs on this forum so feel free to move it to the Trash Can if you want but I have often wondered about this: How would have our history (especially the history of space exploration) have been different if the Earth had a moon with a breathable atmosphere? I think that would have changed it dramatically. Edited February 18, 2015 by Mad For Science 1 Link to comment Share on other sites More sharing options...
Phi for All Posted February 18, 2015 Share Posted February 18, 2015 I think our curiosity about what kind of life was creating the oxygen would've been insatiable. 2 Link to comment Share on other sites More sharing options...
sunshaker Posted February 18, 2015 Share Posted February 18, 2015 I don.t know about a moon with breathable atmosphere, but if a planet within our solar system had a atmosphere and also intelligent life, We would now have ships way beyond what we have now, Perhaps even decades of space warfare, If this is the case throughout our universe where more than one intelligent life form exists in the same solar system, it should be something to be worried about. 2 Link to comment Share on other sites More sharing options...
swansont Posted February 18, 2015 Share Posted February 18, 2015 It would also mean a moon massive enough to maintain an atmosphere, which probably has ramifications to our development. 2 Link to comment Share on other sites More sharing options...

Just wait until the Titanides find Huygens sitting on their planet... It would also mean a moon massive enough to maintain an atmosphere, which probably has ramifications to our development. Twin Earth sized worlds orbiting each other, now that is a thought that would have ramifications if realized... Link to comment Share on other sites More sharing options...
Moontanman Posted February 19, 2015 Share Posted February 19, 2015 Video: If the Moon were replaced with some of our planets I like that video, it is good for visualizing sizes of the various planets and the difference between what they look like to a camera and to our eye. The full moon looks enormous as it comes above the horizon to the naked eye but to the camera is it considerably less impressive if I understand correctly this is due to our brain and how it interprets visual data under different circumstances. If we were in orbit of Jupiter or Saturn what a magnificent sight those planets would be to those who lived on the side of the Earth that faced the giant planets, can you imagine the legends that would have arose from watching the clouds and storms not to mention the dance of all the smaller moons which would be visible discs in the sky as well and the rings of Saturn! Wars might be fought to claim the lands under the visage of "god" I was a bit disappointed at how small Venus looked, i expected it to look a bit more like Uranus... When I imagine a twin Earth sized planets i visualize them being so close they share an atmosphere and whirling around each other in hours, may as well be as dramatic as possible Link to comment Share on other sites More sharing options...
