>I guess I'm just not a big fan of Nolan himself. I couldn't sit through Inception even though I tried to watch it at least 3 times. These kind of movies rely too much on short, loud, shocking, and emotional scenes to keep the audience captivated and I can't stand that shit.

Wait what? Did we see the same Inception? Inception didn't have any emotional scenes. It only had scenes where people were being emotional.

The whole film was a dry emotionless philosophical stroll through a virtual reality hidden in a virtual reality hidden in a virtual reality hidden in a virtual reality...

I just wondered, I have never heard of a microscopic telescope. By this I mean a device along the lines of a large nature-style camera lens or traditional telecope that is able to zoom in to the target area of a physical item and produce a 3d environment of that area through the lens? Surely theres an infinite amount of detail from a physical item We have all this advanced astronomical technology these days to look at things that lie in the distance. What would happen if technology was put into microscopic telecopes thanks everyone

TLDR: a lens of intricately layered magnifying glasses that self multiply

The resolution of a telescope can be limited by a few things, diffraction, the atmosphere, the quality of the optics and the sampling of the camera. You suggest adding a microscope, in optics that concept already exists as focal extenders which increase the effective focal length of the telescope increasing the magnification. The problem is more magnification will only improve the resolution of a telescope if it's resolution is sampling limited, that means the pixels are too big to capture the full resolution. The vast majority of telescopes are not sampling limited, generally they are limited by the atmosphere or by diffraction if they are in space or use adaptive optics. No matter how much you increase the magnification you will never beat those limits. There is not an infinite about of detail you can achieve, there are physical limits such as diffraction. A telescope like Hubble is diffraction limited what you suggest would not improve it's resolution. You can only improve on diffraction buy building a bigger telescope or using shorter wavelengths.

You can't use this to make a 3D map either.

Hi guys.
When I'm high at night, I love to watch moon/stars/...
So I figured it would be nice to look at it with a telescope ...
The problem is that I know absolutely nothing in astronomy !!!
I need some advice for choosing a telescope not too expensive (Max budget: $200)
>What can I expect to see with that?

I know it's been a few months, but maybe you'll see it if you haven't bought one yet. I have a Celestron NexStar 102GT and it is awesome. It has the capability to track objects and it has decent magnification. It was right in the $200 range iirc, but I bought it years ago. I'm able to see the rings of Saturn(though it just looks like one ring). A couple of nights ago i realized Jupiter was in the sky and I was able to actually see some of the differing colors of the cloud bands. That was really cool. Pic is a snapshot from a video I took using a mount for my phone.

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?

https://www.youtube.com/playlist?list=PLAE712CF17EC14903

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?

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.
