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.

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?

It boils down to the Drake Equation and imho the probability of microbiological life evolving on habitable planets.
To quote wikipedia:
And now the tremendous pitfall:
>f_i is the fraction of habitable planets where microbial life arises. Ward and Brownlee believe this fraction is unlikely to be small.

This could be incredible small for all we know. From the current understanding of microbiology cell organelles are hypothesized to have formed from random convergence. Considering the relative size of these (in terms of number of molecules) it might turn out to be incredible improbable to happen.

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 the big bang happening constantly?

In a way, yes. There was no definite point where whatever before went boom. Rather, the Big Bang refers to the inflation of the size of the universe, right after its inception. And by inception scientists means the time when current physical laws came into existence. As the universe (read; space itself) still increases in size, you could say that the inflation(in other words the big bang) never stopped. It just reduced its speed.

In a way, you could say that the universe is the Big Bang, as the point the concept refers to set everything in motion and thus is an extended part of it.

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.


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?

>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.

Its pretty neat in theory, but we can't fully accept it as fact until we have direct observation. Which will be incredibly hard. Think of it like this: whatever is out there is incredibly faint , even with a high albedo, due to its distance from the sun. Next, it will also be incredibly cold. If it is gaseous then its outer gas envelope will be downright frigid.

To find this object which is faint and cold, we will need very powerful infrared telescopes, which are unfortunately rather lacking right now. And also, based on the orbits of perturbed KBO's and sednoids, the object is likely at its aphelion of its orbit, meaning its at the point farthest away from the sun, making it more faint and difficult to detect.

Idk guys, people have theorized "planet nine" for quite awhile. I'll wait until they come out with a peer reviewed paper with 6σ correlations.
