The best explanation is a comet having broken up in an extremely regular pattern at a really silly angle. A possibility raised is a civilization setting up a dyson swarm, or basically a bajillion solar panels coordinating with themselves to stay in orbit and produce the energy a super advanced space faring civilization needs, but on the other hand the system is dark in infrared light suggesting that the light from the star isn't being absorbed and converted into anything (which heats things > releases infrared, because nothing is 100% efficient)any ideas on where the infrared might be, given that it's a dyson swarm?

The Fermi paradox is not a fucking paradox. It's completely reasonable that in a universe this large and the short amount of time we have had are ears open looking for radio broadcasts AND the fact that intelligent life evolving or even evolving with the senses that would make radio waves a logical invention for them is highly unlikely. Given what we know about how many planets are in the habitable zones of stars. It's totally reasonable that we have not heard a thing from anyone. Maybe if we listened for like I don't know 3 million years THEN we can safely say "yes fermi was right this IS a pardox" can anyone prove this idea wrong? 69 posts and 14 images omitted.

Apollo 9 tested that astronauts could survive in low earth orbit below the 1,000 km mark where the Van Allen Belts begin. >The clunky mechanical engineering of the time combined with the human publics unawareness of how gravity on the moon effects objects differently than on Earth lead to this kind of Qausi-hoax to be implemented.>It was implemented not for some nefarious reason but rather to protect our astronauts from dieing the minute they entered the belts, haven't you ever wondered why they keep the International Space Station so low in orbit?https://www.youtube.com/watch?v=AOHMUQn_x7Qhttps://www.youtube.com/watch?v=GIYdF7YlX3ohttps://www.youtube.com/watch?v=yLw9a5t-sUshttps://www.youtube.com/watch?v=7-iCm9S53Johttps://www.youtube.com/watch?v=lwVqVu5Tl-kDoes anyone have more info on this?I'm not saying we didn't land on the moon but the radiation from the Van Allen Belts would simply be to much for a human body to take but a mechanized American could have survived. 15 posts and 4 images omitted.

About 3 times the mass of the sun was converted into gravitational waves in a fraction of a second — with a peak power output about 50 times that of the whole visible universe. By looking at the time of arrival of the signals — the detector in Livingston recorded the event 7 milliseconds before the detector in Hanford — scientists can say that the source was located in the Southern Hemisphere.Get hype! 11 posts and 1 images omitted.

Their ultra-compact density is what gives them their swag about the vacuum of space.If white holes were real, then how would black holes continue to grow and increase their gravity? Debris, planets, stars and other space stuff 'slows' as it reaches the center of the hole as I understand it.

We've got the resources to spare.We'll definately see atleast a man on Mars, probably the start of a colony too (never bet against Elon). Maybe a base on the moon, but my bet is that a race to Mars will be kicking off soon and the moon will be a sideshow, R&D for Mars colony tops.Maaaaaaaaybe Skylon, not holding my breath on that one though. Ion propulsion should get much better and if we get fusion knocked down in a decade or 2 that could feasibly take us to a nifty fraction of C. Alcuibierre drive seems like a pipedream, but you never know, would require something like a fucking anti-matter power source probably, though perhaps a large enough fusion reactor would do too...If Elon gets his MCT concept with the BFRs done & produced, space mining probably will be feasible then. 100 tons to Mars yo, could probably haul serious cargo from the asteroid belt too since it wouldn't have to fight the gravity well of Mars.AI most likely too, don't know if superintelligent AI, depends on how fast the AGI takes off, though looking at machine & deep learning these days it'll probably take off like a rocket.Humanity's technology is on an exponential rise, just think how much the world changed between 2005-2015 compared to 1995-2005.

Floating colonies on Venus View Thread Reply Hide Arthur Eddington - Sun, 06 Dec 2015 16:45:02 EST vB+y87GU No.55850 File: 1449438302494.jpg -(34599B / 33.79KB, 556x334) Thumbnail displayed, click image for full size. What does /sagan/ think of this?I think it's a pretty fucking sweet idea. I wonder what sort of materials you could use that are both light weight and durable enough for a floating Venusian colony. I had an idea that could help with the buoyancy of the thing: non essential parts of the structure (floors and walls) could be made out of brick like objects that are either vacuum hollow or filled with a gas like helium at very low pressure. They would be brick like objects because many could be punctured without jepordizing the integrity of the station. one could also vent waste heat out the bottom and sides to create a bit of thrust.The only major problem would be in getting people and materials to and from the colony. Then again, I suspect by the time we're in a position to build something like this, navigating the haze of the Venusian atmosphere safely won't be much of a challenge. 14 posts and 1 images omitted.
