@ shadow27 - 17.08.20 - 01:05pm Not strictly space stuff, but anyway.. Quantum mechanical trajectories - future to past - are associated with erasing of memory, since any process which decreases entropy (decline in order) leads to the decrease of entanglement between our memory and observed events. In other words, if we do experience the future (which we might), we are not able to store the memories about such processes. You cant go back in time without this information being erased from your brain. By contrast, if you experience the future by using the usual route past - present - future, you accumulate memories and entropy grows. Thus, a ''brainless'' observer that is, an observer without the ability to store observed events - does not experience time or a world in which we age. This is the de facto 'Space and Science topic' If anyone says otherwise, tell 'em to ''f- off!'' |

In other news.. Our sun may have once had a companion star at one point, which could now be anywhere in the galaxy.. |

It would be pretty easy to find a white dwarf ejected from our solar system. It's not like stars have warp drive or something like that.

Immense dust clouds detected at the Lagrangian points, although difficult to spot it may make us reconsider having space stations at these points in future.. as the dust would possibly interfere with sensitive equipment etc. These dust clouds are replenished by cometary and other debris..

2020 has already been quite a testing year, but NASA has now flagged there is an asteroid zooming toward us. The celestial object known as 2018VP1 is projected to come near Earth on November 2, according to the Center for Near Earth Objects Studies at NASAs Jet Propulsion Laboratory. A day before the US presidential election. |
