I hate the fermi paradox by Otto Struve - Sat, 30 Jan 2016 02:53:49 EST ID:Y6cuAVAn No.55979 Ignore Report Reply Quick Reply

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:
https://en.wikipedia.org/wiki/Rare_Earth_hypothesis#Rare_Earth_equation
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.

My physics teacher has a theory that if the big bang theory then why can't it happen again
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.

>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.

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?

>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.

Not really.
The IAU defines a planet as having enough mass so that it's gravity pulls it into a roughly spherical shape.
Pluto clearly meets this qualification (as does Ceres and many others), but fails on the second requirement: that it has cleared its orbit of similar sized bodies.

I'm a layperson scurrying across the floor of /sagan/, please don't annihilate me.

Is there any reason white holes would exist? From what I understand black holes just keep growing, gaining in mass and gravity magnitude in relation to their mass. Their ultra-compact density is what gives them their swag about the vacuum of space.

If white holes were real, then how would black holes continue to grow and increase their gravity? Debris, planets, stars and other space stuff 'slows' as it reaches the center of the hole as I understand it. Would that mean filling a water balloon with a tiny leak in it is a good analogy for what's theoretically happening?

Overly simplified version: Einstine's math allows for the opposite side of gravity, repellent gravity. Instead of pushing down on the fabric of space time and making a 'dent' it is pushing up and making a 'hill', kinda. Just like the gravity of a blackhole is strong enough to keep light from escaping, the gravity of a whitehole is repellent enough that light cannot breach it.

What if White Holes only exist for a fraction of a second and in the wake of their brief existence form entire universes in a multiverse.

tl;dr the Big Bang was, in fact, a White Hole and we are all (entropy, spacetime) that endlessly falling 'hill' (as opposed to a black hole's infinite depth) that will eventually tear and fizzle.

There will always be shit to fix on Earth, that can't stop us from going outwards. We've got the resources to spare.

We'll definately see atleast a man on Mars, probably the start of a colony too (never bet against Elon). Maybe a base on the moon, but my bet is that a race to Mars will be kicking off soon and the moon will be a sideshow, R&D for Mars colony tops.

Maaaaaaaaybe Skylon, not holding my breath on that one though. Ion propulsion should get much better and if we get fusion knocked down in a decade or 2 that could feasibly take us to a nifty fraction of C. Alcuibierre drive seems like a pipedream, but you never know, would require something like a fucking anti-matter power source probably, though perhaps a large enough fusion reactor would do too...

If Elon gets his MCT concept with the BFRs done & produced, space mining probably will be feasible then. 100 tons to Mars yo, could probably haul serious cargo from the asteroid belt too since it wouldn't have to fight the gravity well of Mars.

AI most likely too, don't know if superintelligent AI, depends on how fast the AGI takes off, though looking at machine & deep learning these days it'll probably take off like a rocket.

Humanity's technology is on an exponential rise, just think how much the world changed between 2005-2015 compared to 1995-2005. We probably can't even imagine the shit that will be around in 60 years.

A huge rock is headed straight for earth

We wrap a tarp around it with a space craft
Fill the tarp with a heavy gas
Once the pressure is high enough inside the tarp
We turn on rockets compressing the gass as much as possable on one side of the tarp
Then we blow up a nuke
Changing the course of the rock enough not to kill everyone on earth

What does /sagan/ think of this?
I think it's a pretty fucking sweet idea. I wonder what sort of materials you could use that are both light weight and durable enough for a floating Venusian colony. I had an idea that could help with the buoyancy of the thing: non essential parts of the structure (floors and walls) could be made out of brick like objects that are either vacuum hollow or filled with a gas like helium at very low pressure. They would be brick like objects because many could be punctured without jepordizing the integrity of the station. one could also vent waste heat out the bottom and sides to create a bit of thrust.
The only major problem would be in getting people and materials to and from the colony. Then again, I suspect by the time we're in a position to build something like this, navigating the haze of the Venusian atmosphere safely won't be much of a challenge.

>When you have nearly limitless energy and raw materials on hand

World's larges caveat, I didn't know we were in the Star Track anything-can-happen universe. Yes, I meant resource extraction. Lets go get asteroids made of platinum and helium-3, not play pretend.

Well obviously we need proper space infrastructure before we go colonizing and building shit all over the place. However, once that is established, everything becomes possible. I can try to dig up some articles I read about things like a Dyson swarm or asteroid mining having huge upfront costs, but massive returns in terms of energy and raw materials.
If you just fold your arms and say "well we can't do it tomorrow, so let's not even speculate about it." I frankly have no interest in talking to you.

Humans go places and do things to get stuff. Not just to do it, those emotions are just used to motivate people. Every great explorer was after land, gold, slaves, riches. I want riches. The asteroid belt is where its at.

I wouldn't want to go to Venus, there isn't anything there. You can't land on the surface, no moons, no nothing, bbbbooring. Even in your super-future there will be shit-holes no one will want to go to. Look at the US state of North Dakota, a giant frozen field full of self-destructive Native Americans, up until the last 10 year or so, it was fucking empty because all that was there was grass and nothing. But then fracking happened and then there was an oil boom and then 100,000s of people looking to get rich, and most of those people are blue collar folks with nothing else going for them. The blue collars go loose limbs getting the riches to pipe back to cities to be profits for rich owner of industry.

This is exaclty happening now, SpaceX, ULA, Virgin Galactic.

Given our lives now, i know in 300 years there will be a miserable dick job of 'asteroid miner'. So you didn't go to college and you are a physically capable young person, get your ass to space and go get some stuff.

I'm not folding my arms, I like realistic sci-fi. In your universe, I want magic powers like the force and shit.

Also, your energy source better be infinite because of this:

Well obviously colonization of Mars and Venus and the construction of space habitats would take place within the context of a well established and rapidly expanding space economy. I don't have to tell you that there is an incredible abundance of resources between Mercury and suburban Jupiter. In the midst of taking advantage of this tremendous windfall, it only makes sense to put habitable places where we can. If for no other reason than as a way station and a refuge. (think a stop for fuel or something at a space station orbiting Venus on your way from Earth to Mercury or something)

>I wouldn't want to go to Venus, there isn't anything there. You can't land on the surface, no moons, no nothing, bbbbooring
The most brutal hellscape in the solar system is boring to you? I don't want to insult you or anything, but whaaa? I don't know how any place in our solar system could be considered boring (well, aside from the MASSIVE expanses of literally nothing, but that goes without saying)
>you can't land on the surface
With currently existing caveman tech it's not a very good idea.

>Given our lives now, i know in 300 years there will be a miserable dick job of 'asteroid miner'. So you didn't go to college and you are a physically capable young person, get your ass to space and go get some stuff.
Frankly neither of us can imagine what human societies will look like in three centuries. If neo-liberal capitalism is still the default system, I'm not sure we'll even be around in three hundred years. Anyway, asteroid mining will likely be almost entirely automated. It makes more sense to have a bunch of durable, easy to produce machines hacking up rocks in space, not a bunch of frail bloodsacks who can't function in an irradiated, freezing, vacuum.

> I like realistic sci-fi
Me too. I love Star Wars, but the lore of franchises like Star Trek and Mass Effect is so much more interesting BECAUSE so much of it is plausible.
