Holy fucking shit guys, my mind is blown.
The unification of QM and GR is HERE!!?!?!

tl;dr: Susskind says spooky action at a distance IS wormholes and the Copenhagen Interpretation and Many-Worlds Interpretation were the same thing all along from different perspectives. HOLY FUCK

Fascinating (if a bit dry) talk. I wonder if he deliberately did not go into other properties of black holes that might negate the limitations he described, or doesn't think they are relevant. Specifically I mean that we know we ultimately can get (all of) the information out of a black hole ultimately as it evaporates due to hawking radiation, could we then not (especially if we are creating a black hole from scratch and thus can make it as small as we want) project entangled particles into the entangled black hole and thus receive information out of the entangled black hole partner in the form of the hawking radiation it emits?

Just thinking about it some more (nb for double post) wouldn't it even be possible to get information out without hawking radiation by manipulating the size of the black hole? If the two black holes share the same singularity then putting mass into one increases the mass of the other, and so if you dumped mass into one it would alter the rate of evaporation of the other which could then be measured.

...I was thinking about Dark Matter. My understanding is that in analyzing the universe, they detect there should be like 3-4 times as much matter as we can account for with stars and such. It just reeks of "luminiferous ether" to me

What if though, there's no invisible matter, but the universe is actually made up of 3-4x more stuff, stuff that is just accelerating away faster than we can see it (faster than the speed of light?). Or is that what is meant by dark matter?

No, according to LCDM dark energy *is* the cosmological constant. Also if dark matter/energy comprise 97% of the universe, how could 3% of the universe generate an opposite reaction almost two orders of magnitude greater (and also where is the room for ordinary matter in this model?)

He's saying if you can achieve an erection on earth while doing a handstand, then you'll definitely be able to achieve an erection in space where you don't have gravity acting against your dick.

I'd assume you'd loose your hand-standing erection eventually as blood flows into your upper body, though you might pass out before that. Zero-gravity is known to cause a sizable reduction of blood pressure, which is the reasoning behind the claim that getting a boner in space is difficult.

Interestingly NASA sits on data like this but refuse to reveal it thanks to their policies on funny business.

So we have sattelites with further orbit than moon right?
Please give link to an actual photo of earth not some composed bull shit.
Something is going on and this might be the best brain wash ever. Not saying flat earth but hidden land or we just cant get further of some point. Also alot of the other NASA images ...you know, are fakes , there is documentation on this do your research. So a simple request , a photo of earth please :)

Have a nice day :) !

I first became interested in space exploration because of this website nearly eight years ago. Over that time space has piqued my curiosity enough that my dream is to work in a large observatory, or in a lab constructing instruments for spacecraft. I've spent a lot of time learning about the universe, and have simultaneously become interested in philosophy. I'm just really interested to learn new things about reality. It's such a marvelous and incredibly complex place, teeming with things to be discovered.

I want to know whatever is possible to know. Some things we might never be able to know, but I'm most certain that curiosity, as well as necessity, will drive our species towards distant planets in search of answers and new ways to survive as we go out. I really do hope that's how it plays out. Out of all of the possibilities, I think we'll always have a desire to travel into the next greatest frontier. We might travel inwards with digital worlds and biosynthetic machinery, but I believe the physical domain will continue to hold some deeper allure.

But Venus is toted as the prime example of what could happen to our world if it got choked completely. Seems more likely a good idea to learn to live indefinitely in artificial environments like stations or Moon bases. In the long run that will be the most common living space moving forward into the cosmos.Terraforming is in the distant future and by the time we could do that we would already be able to live in orbit of every major body in this system if not leave it already.

>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)

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?
