All you need is to program the goo to build Von Neumann probes from asteroids and them using to spread.

Can't imagine any species would do such a thing but hey humans are crazy enough for nukes and M.A.D. so who knows?

I have deduced that all living organisms are White Holes. I call this the Living Organisms as White Holes Theory.

Evidence :
  1. when the cells of a living organism divide, it emits minute levels of light.
  2. living organisms create and excrete their own matter.

Please help me compound on this theory I want to talk to a real scientist. I have more to add but I need to go do chores. More later, like being four dimensions opposite of zero. (thought. The final frontier)

I used to think that maybe a life form is like a bubble of negative entropy. All around the universe matter is getting less organized as systems disperse their energy, but in life matter harnesses energy to organize itself temporarily. But I was wrong. It doesn't make any sense to think of life as a closed system. We radiate so much heat and excrete so much shit that there isn't any logical boundary to call a bubble. There is temporary organization, but it is constantly part of the greater universe. Everything is causally linked. Especially EM waves. Photons are being absorbed and radiated by your cells. In a trippy way, doesn't that make you a physical part of your surroundings?

As far as I understand entropy, clustering of energy like in the form of planets or lifeforms is in fact a part of it. A zero-entropy universe would be stable, or in other words uniform.

But long term, this would be cheaper than combustion. This would also work for manned missions.

You'd have to start decelerating 50% of the way there, if they're doing both with lasers. But they'd probably just use combustion to decelerate, which would significantly reduce weight too. Since it's for stopping and not the initial thrust. So I think that might work.

I realize it works great if you're just sending things out, but why develop this huge and incredibly useful ability and just use it to send out a dozen more voyagers?

>The biggest hint is that one of five speakers at the news briefing will be Lujendra Ojha from the Georgia Institute of Technology in Atlanta. Ojha made headlines in 2011 when he co-authored a study suggesting that liquid water flowed during the warmer months on Mars.

>He said at the time that, by accident, he noticed irregular features in images taken for another study of gullies in Mars craters. Using a computer algorithm to monitor changes over time, he began to see "finger-like" features and streaks that strongly resembled water. They would appear during warmer seasons and die away during cooler seasons. He has conducted research ever since, to determine if it is definitely water.

Just went safe mode, for seemingly no reason. Either NASA saw something that they don't want us finding out, or some kind of aliens are trying to prevent their discovery. I mean, Pluto seems completely, artificially placed. It orbits on an entirely different plane than the rest of the planets in the solar system. I'm not a /tinfoil/ faggot, and I'm not talking about "greys". I want to have a serious discussion on the possibility of this, because I got super stoked about seeing high-res pictures of Pluto after reading about the last few developments, and this just seems too coincidental.

>We have exactly one datapoint for how rationally a species capable of space flight behaves, and it's "not at all".
I know his claim is baseless, but your implication is a logical fallacy. A lack of evidence showing that species capable of space flight behave rationally is not evidence that none (can) behave rationally. Not to mention there's a huge difference between space travel at the distances required to reach us/other planets supporting sentient life, and just being able to make it into space. We don't have even a single data point at all in regards to the level of rational behavior a species capable of space flight at those distances possesses.

Your argument is shit. His might be shit too, but he's not positing that pluto is an alien space station that houses blue-visioned aliens and serves as a research lab where they perform tests on humans. Therefore, your argument is shit and your criticism of his criticism is retarded.

https://en.wikipedia.org/wiki/KIC_8462852

tl;dr - star has some really odd brightening and dimming patterns inconsistent with any hitherto known natural phenomenon. 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? Or opinions on the correct natural explanation?

This is a 1973 BBC/20th Century Fox/ABC production, created by Dr. Who's Terrance Dicks. It only ran for 6 episodes, and didn't take off, mostly because it was just a little too realistic, concentrating on scientific accuracy over B.E.M.s and green bitches and space dogfights, but I thought it'd find some new fans here.

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?

But evidence of life starts very soon after the earth cooled.
This implies either those molecules are incredibly likely to occur on a scale of millions of years, and certain to occur on a scale of billions of years given pre-earthlike conditions.

For prokaryotes it seems the odds are in their favor, but eukaryotic life which is near required for multicellular life needed almost half the lifetime of Earth to develop. Which makes sense as they were born from symbiotic relationships between different prokaryotes, something that need specific spesializations to occur beforehand.

Is it possible that the universe is expanding because of big bangs are happening constantly?
How does this fit with the big bounce theory?
The first issue I see is how the big bangs are being formed and in what enviroments.

I gotta add that there are hypotheses based on theoretical math that inflation is a neverending process, that is constantly spawning "universes" in different places from our universe.

I dunno man, I watched a lot of documentaries on theoretical physics when I smoked weed everyday and grew my own mushrooms and tripped every two weeks because tripping while listening to some astrophysics documentary is a fantastic way to get lost in closed-eye-visuals of space.

The Van Allen belts put out radiation that can be extremely detrimental to a persons health and could even lead to death. NASA itself has claimed it can't get through the radiation belts.

https://www.youtube.com/watch?v=NlXG0REiVzE
https://www.nasa.gov/content/goddard/van-allen-probes-spot-impenetrable-barrier-in-space

Now that NASA has tentatively acknowledged that the Van Allen Belts can't be passed, how is it we were able to land a man on the moon?

>the answer may surprise you

New evidence shows that robotic drone type machines may have been used inside the Apollo astronauts suits while the astronauts remained safely in low earth orbit. 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?

Does 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.

>Based on the observed signals, LIGO scientists estimate that the black holes for this event were about 29 and 36 times the mass of the sun, and the event took place 1.3 billion years ago. 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.
