As Astroscientists, we are going to challenge that claim.]]> 2017-08-13 03:54:42 UTC https://padlet.com/len_halprin/tv6mhqqxxmga/wish/180820774 len_halprin https://padlet.com/len_halprin/tv6mhqqxxmga/wish/180820775 The background image is a 1970s proposal for a large, man-made, slowly-rotating colony located at the L-5 point in space, complete with gardens, trees and rivers, and capable of supporting thousands of inhabitants.]]> 2017-08-13 03:54:42 UTC https://padlet.com/len_halprin/tv6mhqqxxmga/wish/180820775 https://padlet.com/len_halprin/tv6mhqqxxmga/wish/181165761 L5 is a gravitational stable area the same distance from earth as the moon. L5 is the most stable gravitational area and if we placed a artificial gravity space station there it would stay there forever.]]> 2017-08-15 23:02:36 UTC https://padlet.com/len_halprin/tv6mhqqxxmga/wish/181165761 https://padlet.com/len_halprin/tv6mhqqxxmga/wish/181165820 The idea that 'is no Planet B', is not entirely wrong, but it's not entirely true either. In every two body gravitational system, there are five Lagrangian points. When something is put into them, that thing won't move from that point. However, they aren't all stable, but L5 is the most stable out of all of them, and it is a very stable place.]]> 2017-08-15 23:03:23 UTC https://padlet.com/len_halprin/tv6mhqqxxmga/wish/181165820 https://padlet.com/len_halprin/tv6mhqqxxmga/wish/181166018 Owen And Oliver]]> 2017-08-15 23:05:56 UTC https://padlet.com/len_halprin/tv6mhqqxxmga/wish/181166018 https://padlet.com/len_halprin/tv6mhqqxxmga/wish/181166391 The L-5 colony is the idea that society could plant a huge space station, that could have thousands of people in it, and this colony would be placed in the L-5. This would mean that it wouldn't drift away and crash into somewhere.]]> 2017-08-15 23:11:11 UTC https://padlet.com/len_halprin/tv6mhqqxxmga/wish/181166391 https://padlet.com/len_halprin/tv6mhqqxxmga/wish/181166654 To make water in Space you can combine Hydrogen and Oxygen togeather and then ignite it to start a chemical reaction which turn s it into water.]]> 2017-08-15 23:14:26 UTC https://padlet.com/len_halprin/tv6mhqqxxmga/wish/181166654 https://padlet.com/len_halprin/tv6mhqqxxmga/wish/181168082 The L-5 space station's gravity would work by the parts of the space station with civilization in it slowly turning at a speed that would push the things in it to a side of the cylinder which would be the ground for us. ]]> 2017-08-15 23:32:27 UTC https://padlet.com/len_halprin/tv6mhqqxxmga/wish/181168082 https://padlet.com/len_halprin/tv6mhqqxxmga/wish/181168712 To survive in this space station, we would need to bring things from Earth. These things would be building materials, soil, plants, seeds and more things like that. We could start from scratch in this paradise, and it would be just like Earth, except with a curve to the ground.

The reason for this is that science says that it is possible to this, with the fuel, plants, food and the L5. But the problem is that there are lots of people who won't do it because they care too much about themselves and money, rather than the future of humankind. In the medium term it could be done if everyone agrees to it and we start the project right away. All the evidence suggests that we can do it, so why not start now?]]> 2017-08-22 22:25:14 UTC https://padlet.com/len_halprin/tv6mhqqxxmga/wish/182208511
