If aliens was ahead of us in technology then they would surely know we are here? Just like we know there are biologicaly inhabitable planets out there.

>wouldn't have had time to make the journey.
Depends on how far they are from us, right? I guess it's like with stars and us: the stars we observe every night are already dead.

>We haven't been broadcasting evidence of intelligent life for even a century.

I think aliens might just be too different and advanced for us to even recognize as life and they might be able to travel around so fluidly through the universe that it's not that they are visiting us because we are such fascinating creatures, they are visiting here because they go around everywhere all the time anyways, I'm sure they spend time on Jupiter too

A crack pot idea I was thought of last night is this: There's some good reasoning out there that the universe exists as described by a model of the holographic principal, there have also been some recent papers that suggest the phenomenon of volume and orderliness in space is created through entanglement of information on the holographic cosmic horizon that we are all smeared across.

My idea is that aliens have some sort of super quantum computer (or something beyond that) that can decode all of cosmos and they are able to somehow alter the entanglement states in order to manipulate the properties of volume. I bet they can create black holes like it's nothing.
But I think that would explain the behavior of UFOs, from how they seem to morph shape, and split apart and reform. They are so hard for people to describe because they are taking quantum phenomenon and blowing it up to real world levels. I think when a UFO "explodes" without leaving a trace, it's just some inherent collapse of the system of altercations to the holographic horizon normalizing itself.

Granted that's all assuming UFO reports are even accurate, but like I said, crack pot, it's just fun to think about even if it's not real.

Hahaha that's awesome.
It would be an interesting statistic to see how the numbers change from populations with lots of alien cultural references to others were it's less prevalent, and how it changes with the scientific education levels of the respective populations effect the out come as well.

I've seen one ufo, it was probably a meteor, about twice the size of the full moon, comparable color and brightness, but it didn't have a tail and it flew right over me. I've seen large (good fraction of the full moon size) meteors before, and the big ones still had tails, but maybe it was a simple perspective issue, as the ones I saw with tails were all on the horizon. It still scared me though and I'm a super tough guy whose not afraid of anything

Yeah, but we're really far away too. If we were closer (and blocked out light from other sources, we see dim objects near very bright objects by covering up the bright object), some structures would be brighter, to an extent.
But nebulae are so big and diffuse they've be invisible up close. The face of OP's unicorn is about a light year long.

The IAU currently does not recognize space-unicorn as an alternative to light-year.

They're definitely *real*, but they're not as visible as the photos make them appear. Most of those awesome nebula photos are long exposures, yes, but they're also composites of infrared, x-ray, and visible light, with some coloration and hue/contrast added to make them "pop." It's a real thing in the photo, but it's not the "natural" way it looks.

This is a volcanic vent in Antarctica. The area around it is not habitable. The planet will become colder than that.

Geothermal and nuclear plants are the only methods of any scale that could be run for years if there was a catastrophe.
If there were enough proximity, farms could be set up in underground salt mines to last a few years.
Ultimately, nuclear and geothermal are the only power sources that aren't derived from our sun.

If my imagination is allowed to run wild, I would put the earth in orbit around Jupiter, close enough to cause a decent amount of geologic activity and keep some sort of an atmosphere, even if it's toxic and much less dense than ours is today.

The center piece of civilization would probably be fusion/fission nuclear reactors, we could mine hydrogen from Jupiter. But we would need manufacturing hubs, mines, and genetically modified plants in vertical farms. I think it might be best to put residential areas around hydrothermal vents. But the other stuff will probably need to be above ground

>People take the mathematical discoveries for granted, but they tend to forget that it was Kepler's imagination that allowed him to formulate the theory.
But without the new model actually fitting the available data, the theory is as useful as the polemic model.

When Greek philosophers said "lol if we divide something enough, surely we'd get to a point where we couldn't divide it anymore", it was as constructive as "lol if I shot an arrow at you, to reach you, it would have to go half way to you, and to do that, it would have to go half way of that, therefore it could never reach you".

"what if the universe is a high-dimensional object constantly rotating within itself" doesn't make any testable predictions, explain any data, etc.

>But without the new model actually fitting the available data, the theory is as useful as the polemic model.

It was Kepler's vision of God communicating with mankind on a cosmic level, via recognizable geometric shapes, that incessantly drove him towards the pursuit of knowledge. He struggled through war and personal strife to get the data, not because he wanted to prove elliptical orbits (that part was incidental), but because he wanted to prove that his starry-eyed dream of a physical connection to the spiritual realm was true.

>When Greek philosophers said "lol if we divide something enough, surely we'd get to a point where we couldn't divide it anymore",

It was their way of estimating the area within complex shapes and it worked well enough for that purpose, unlike anything before. It worked so well, the Chinese reinvented it hundreds of years after the Greeks did.

People really screwed up when they made the assumption that the ancient Greeks knew all the answers, and any questions about the metaphysical weren't to be tolerated if they didn't conform to the religious teachings of the time. (seeing a pattern yet)

>"what if the universe is a high-dimensional object constantly rotating within itself" doesn't make any testable predictions, explain any data, etc.

But it might make people take the same data that's in front of all of us and see it in a new light. And as history has repeatedly shown, they might even stumble upon a world-shattering discovery in the process, which happens to hold true in reality.

You're confusing a few things there. Inflation is not the expansion of the universe, it was a very rapid stage of expansion in the very early universe which ended shortly after. What drives the expansion of the universe is like momentum, it was expanding so continues to now. What drives it's accelerating is a different question loosely dubbed dark energy which is really a name for any model which sets to explain it.

Personal difficulty does not change the facts, Kepler was brilliant but the data was stolen.

And no the sentence "the universe is a high-dimensional object constantly rotating within itself" isn't going to cause anyone to stumble onto some new cosmology, it's so vague it doesn't many anything, it's technobabble.

So if I'm correct, every galaxy has a supermassive black hole at the center of it. Every galaxy was once an active Quasar and then cooled after the black hole at the center of the galaxy spewed and consumed all the matter around it. So if a black hole has angular momentum at the center of a galaxy, does that mean the galaxy would result in a spiral shape? And would non rotating black holes instead form more of an irregular galaxy shape? I'm thinking in terms of galaxy evolution and the various shapes different galaxies take. Cheers.

You're both sort of right. Before major mergers when galaxies shave a lot of gas and are actively forming stars most of the big ones are spirals, some of the small ones can be irregular bit that's a different story. Left to it's on devices a spiral will not evolve or normalise into an elliptical.

A major merger is when two roughly equally sized galaxies collide and merger. It is believed elliptical form major mergers of spirals. As part of this merger the gas is usually stripped out and star formation shuts down with nothing to make stars out of (After the merger is finished). When it reaches a steady state it will be an elliptical, it will not evolve back into a spiral. The reason ellipticals have older stars is because they don't form any new ones, the oldest stars in each galaxy will not be significantly older or younger than the other.

Good question!
This mission is designed to find candidate star systems for follow up observation by more sophisticated telescopes, like the JWST or GMT. What this means is that our mission is to simply characterize and catalogue as many candidate systems as possible. After speaking with a professor on the program yesterday, he explained that simulations of one year of operation showed a potential catologue of up to 75 earth mass exoplanets, up to 150 between earth and Neptune mass, and more in the Jupiter size class.
However, These candidates are going to be in orbit around the best candidate stars for water to exist, namely red dwarfs and smaller main sequence stars. It is hard to say which ones could have all three phases. At least what TESS can tell you is the mass, period, and a brief sniff of the atmosphere (if you subtract the star spectra before a transit from the spectra during a transit, you get a vague idea of the atmosphere composition).

Alas I have not gotten my patch yet. I'm hoping to score a TESS patch and a CHANDRA patch, cause that's' another one of our missions.

The meaning of life is subjective.
The meaning of our lives to aliens could be rather demeaning to our sense of ourselves and I doubt aliens are going to tell us we are to rule the universe or whatever.
I think life has a general role to play in the future of the universe, as it is a natural byproduct of the Big Bang, but I don't think that would even manifest itself through mere biologic organisms. I think a mastery of quantum technologies will have a dramatic effect on the biology/physiology/psychology of humans.

Hey all

I just got a new video card and decided to fire up the old BOINC to see how it stacks up to the old ones I had. At the zenith of my BOINC days I had x2 5970's doing 4 workunits, one for each GPU, every 1:30-2:00 minutes each. This 7990 that I just got is doing 2 workunits in 12 seconds for the easy ones and 30 seconds for the longer ones, but they have them mixed in with each other. So in the time it took to draw a 3d map of the cosmos in one unit for my old setup if I only counted one card, my new one is doing the work of just over 4 of my old cards in the same amount of time.

Is there still any interest in this now that Bitcoin shit the bed finally? We can start using our unused CPU and GPU cycles again for science if you want to join the team, we have teams for most of the major projects, Rosetta, Milkyway, Primegrid, etc.

2 days plugging away at it on and off (not even really trying), I'm already in the top 300 out of nearly 3 and a half million people in recent credit.

Cool beans, interpol.

I like to say "boinc" and I like what they're trying to do but my graphics cards sucks balls, so keep up the good work!

>NASA researchers are planning to create the coldest spot in the known universe inside the International Space Station.

>Researchers like Thompson think of the Cold Atom Lab as a doorway into the quantum world. Could the door swing both ways? If the temperature drops low enough, "we'll be able to assemble atomic wave packets as wide as a human hair—that is, big enough for the human eye to see." A creature of quantum physics will have entered the macroscopic world.

100 PK is their target. I think that the previous experiment proved one could reach that temperature. This experiment is intended to test what would happen at that temperature. Those are different objectives.

That pic is screwed. The pieces in Chinese Chess are placed on the intersections of the lines, not inside the squares. nb

Western audiences wouldn't get the reference using any other board, but the philosophy behind ancient Chinese chess aphorisms remains, hence the disconnect between what is seen and what is heard.

I recently came across a wikipedia article on carbonaceous chondrites, a particular kind of asteroid.
Www.wikipedia.org/wiki/Carbonaceous_chondrite


But what makes these awesome is that they are up to 20% water, contain amino acids (which is very interesting), and sulfur compounds and other biologically useful compounds.

To me it seems readily apparent that these things could of fueled the formation of life during the earths construction. But if these things brought life to earth, shouldn't we bring them to planets and moons we colonize? I mean, work backwards man.

A cool thought is that the first asteroid we bring to mars will be the beginning of its inevitable terra formation

Yes, I'm aware this is disputed, but it does explain why Venus's plate tectonics stopped, if it ever had any.

Maybe we could build a giant lens in between mars and the sun. Tons of giant sheet like lenses layered over a huge distance, possibly all the way inside mercury's orbit, set up kind of like the death stars planet destroyer. The ones closer to the sun would be a mix of the future lenses and mirrors, concentrating the photons into a series of additional sheet lenses inbetween the sun and mars. The lenses in this part would play two primary functions, further concentrate the sun, and also block protons emanating from the sun, (assuming protons actually move in a straight line from the sun, I have a hunch they don't.)
Of course it would be a massive infrastructure project, be we're terraforming baby. The technology I'm talking about will also be here soon, if not on this scale.

Objects closer to the thing they orbit have a shorter period, though slower velocity than objects further out.
The interaction between two object's orbits produces 5 areas where technically an object could sit relative to the planet. In practice, objects don't remain there for very long (Lagrange 1 and 2 are particularly unstable) until reactions with the other bodies and the solar wind pulls them out, except for Jupiter, because Jupiter is fucking massive.
Any large sheets put outside a magnetic field in space will function like a solar sail, being pushed back by the solar wind it catches/deflects.
Magnetic sails work the same way, except they use an imbalanced in charged particles captured in a magnetic field to deflect charged particles.

Yeah I thought about that after I posted it, can't just stick whatever I want wherever I want, there are no arbitrary orbits
