Our planet has a steadily growing shell of orbital debris. This space junk is most concentrated in low earth orbit band. Currently there are somewhere over 1,100 active Gov't and private satellites in orbit, as well as over 2000 that have ceased functioning.
That's just the satellites, as it is estimated that there are over 600,000 pieces of bullshit between 1 and 10 CM just waiting to blow a bunch of holes in any given mission.
Now, if a large enough object were to collide in LEO, or some kind of explosion, these debris objects will begin colliding, creating shrapnel, and impacting MORE objects in a runaway feedback reaction.
This gives us a number of problems, the first being that it totally kills any launch viability for the foreseeable future as well as destroying all the satellites we already have in orbit. The other major problem is that as these thousands upon thousands of objects get kicked around much like atoms in a nuclear chain reaction, a good number of them will de-orbit and enter earth atmosphere causing heating due to air friction. That is bad for obvious reasons.
So /sagan/ how do we take preventative actions against this? Do we even need to worry? what would a post-cascade earth be like?

So I feel compelled to add this. Something would always hit it, due to dust. I mean, check these links out and read up on dust:
http://atropos.as.arizona.edu/aiz/teaching/nats102/mario/solar_system.html
http://stupendous.rit.edu/richmond/answers/dust.html

So like, if there was a black hole out there, with dimensions of 7"....If it lasted for this long [hawking radiation and all that], then it would probably have a faint infrared glow from the accretion disk formed around it. It would have an accretion disk because all that gas its running into has to go somewhere. Its hill sphere is the effective radius of a planet with mass x, not just 7".

No, because black holes are rarer in the universe than planets, and a black hole with a small enough mass to cause those effects but without eating the rest of the Kuiper Belt and Oort cloud would be pretty hard to form in the first place. And if it did form, the supernova that caused it would have blasted the rest of the solar system to bits.

>And, presumably, they are using lasers to send the signals -- how else would you send a coherent optical signal over such a great distance?

If I understood it correctly, the supposed signal is not lasers but 'spectral modulation'. Whatever that means, I take it that it's the light from the stars themselves that's supposed to be the signal. The fact that over 200 stars seems to show the same phenomenon either means it's an incredibly advanced interstellar civilization, or an as of yet unknown natural effect.

Agreed, probably more likely it's a yet-to-be understood stellar phenomenon, I mean would aliens seriously spend the time and resources necessary to modify STARS just to send messages? There has to be more efficient methods of stellar communication than modifying an entire fucking star. Like just the amount of engineering to construct a device able to modulate a stars light output seems retardedly complex for communication
Thy being said, maybe it is aliens and the fluctuations in signals has to do with some sort of Dyson sphere like device, not ruling it out. Just saying that aliens are PROBABLY not trying to talk to us by fucking with stars' outputs

Ways to change the spectral qualities of a star:
-pass a prism in front of it
-pass a planet with a spectrally modulated atmosphere in front of it (fancy prism.)
-drop mass with a different spectrographic profile than hydrogen or helium into it
-ignite mass with the desired spectrographic profile with a probe in the photosphere
-like I said before, just send a laser beam with different spectral properties in the same direction as photons from the star are travelling
All of those things would be trivial for a 1K civilization. Does that mean it is aliens? No. But we can't rule it out just because the method seems exotic. It might be hugely practical. I mean, the only thing they can see about our system is the star too, right? If we wanted to send them a message, and knew nothing about whether they are looking for radio signals or anything, the one thing we know they can see about us is our star, so if it can be used to send a message, why not?

I highly doubt that any force Earth generates, except gravity, amounts to difference in the rotation of water in sinks / toilets on northern / southern hemispheres.
The forces in sinks / toilets are so miniscule compared to Earth's. It would only make sense if the water was somehow magnetized.

I'm pretty sure any difference in rotation is due to the shape of the sink / toilet.

This. To add a little bit to what anon said, for the Coriolis effect to actually have an effect on the direction of rotation, the body of water or fluid (why it effects storms, air is a fluid) has to be very large. Something as small as toilet bowls or even sinks have their direction of flush determined by the shape of the bowl and in the case of toilets, how much water comes out around the bowl each flush on each side (more might come out on one side for whatever reason).

There are more than enough resources on Earth to feed and cloth and house the entire world population several times over, but people are still starving and homeless due to our greed and incompetence. We can't make phones that don't blow up or cars that don't drive themselves into a wall. We're still dicking around with fossil fuels and nuclear reactors and steam turbines when we have a natural self-sustaining fusion reactor in the sky that could power the whole planet for millions of years if we just put more research into making better solar cells and superconducting materials and large-scale energy storage. With all our intelligence and resources, we can't make shit work on a planet that gives us everything we need, how the hell are we going to survive on a hostile world where just making food to eat and water to drink and air to breathe is a massive costly endeavor, and one tiny malfunction in our machines will result in horrible catastrophe and death? Is mankind really ready to live in space?

You know, OP, you say we have all the resources here on Earth, yet still there's a lot of people living a life of distress due to lack of things and violence. You say we could fix it all, only if everybody started being logical and humane.
But therein lies the problem - it's just that difficult to change humans on that level. So difficult in fact, that it will probably be easier to build a spaceship, living pods and all that's necessary and send it all to another planet with like-minded people that are focused on one goal - making it work there.

In the sense of the mission, the monetary cost is completely irrelevant. 500 years from now nobody will give a shit about how much it cost. Even if there are failures and people will die, it only makes sense for us to keep reaching out there. Once any life arises, it wants to reach out as far as it can.

I don't think mankind really is ready to live in space, until we actually do it and get ready doing it.

do you think it would ever be possible for 2 black holes to meet? they say they are growing.. which makes it highly probably they will have a meeting one day.

i don't think anything special would happen other than they merge basically. but i had been thinking because of what they eat, what if one day a black hole has consumed to much...

But that presumes there is an unlimited amount of radiation in the interstellar medium. By the time black holes are evaporating en masse, all matter will already have fallen into black holes, so there's no way it could replenish itself with ambient radiation.

>If the universe was born from a white hole it solves everything.
if black holes turn into white holes and birth new universes, that means holographic universe theory is real, multiverse is real (every black hole is its own universe), every single equation is solved, if science simply realized that it was not a singularity but rather a white hole.
>Our universe is inside a white hole, or event horizon.
>Looking at a star 90 million lightyears away is like looking at the star as it was 90 million years ago. is it possible we have not detected life, as we can only view stars in the past - and not as they currently exist?

For example, the big bang theory says the universe started as a singularity. But scientists have no satisfying explanation for how such a singularity might have formed in the first place.

If our universe was birthed by a white hole instead of a singularity, Poplawski said, "it would solve this problem of black hole singularities and also the big bang singularity."

Wormholes might also explain gamma ray bursts, the second most powerful explosions in the universe after the big bang.

Gamma ray bursts occur at the fringes of the known universe. They appear to be associated with supernovae, or star explosions, in faraway galaxies, but their exact sources are a mystery.

It's not about realizing anything. I'm sure plenty of physicists and cosmologists have entertained the idea, but it isn't science when you just make shit up that isn't able to be tested, measured, proven, or disproven to any degree. Cosmology has a bad habit of sometimes delving into the realm of psuedo-science. None of these are even hypotheses, they're simply musings. It could very well be true, but there isn't currently a way to tell one way or the other.

While reading this got me thinking, do the people that write these up actually believe these "facts" or they just go with the thread for the kick of it. Or maybe they're just 15, eager to belong into some kind of social group and wanna feel special/entitled, with their mind not exactly made up what they're experiencing.

Basically the first 18 something disregard gravity (pic related).

19. is a funny one, based on a 16th century argument that stars in the sky should be visibly moving "back and forth" since we're on solar orbit and move somewhat closer and further to them.
20. says a cannon shot straight up should land slightly west because by the time the ball falls back the earth and the cannon should've moved east due to earth's spinning. except the atmosphere spins with the planet.

the rest just made no sense or were downright dumb and i got bored

No, this is pure pseudoscientific blabber.

If this was to taken seriously in any regard...I would want to see peer-reviewed data of some basic things....like spectra of the "object", or maybe something like, hmm, I don't know, orbital parameters? If they caught two images, you can at least roughly infer parameters.
Alas this info will never come to light, because the authors have nothing more in mind than tinfoil-y conjecture.

The ultimatum is that you expect your viewpoint to be correct, that there is some "massive" object passing by the sun, whose existence is inferred by data from a 20 year old satellite.
Moreover, why did you tell me to check if I have cancer? Are dissenting opinions that rough to you?


Also, do you want to know why this is the only source reporting on this? Because its fucking technobabble, made to look pretty in text. You want to know the truth? Any astrophysicist (a broad and international group, i may remind you) would love to have their name associated with definitive proof of ETI or the like.

Whoever wrote that article should be shot.

It's a cosmic ray, if the author bothered to fucking Google it they would have known that. A cosmic ray is a charged particle which hits the detector exciting pixels when there is no light. The same thing as all the other little streaks in that image, the multiple lines are secondary particles. If you look though the SOHO archives you will find thousands. Notice their object turned up months later but was gone just an hour or two later when the next image was taken, because it's not the same thing and it's not a real object. YouTube is crammed with these videos of SOHO UFOs, of course NASA doesn't respond to the same idiots who have been ignoring the response for a decade.

The Apollo astronauts experienced a similar effect with their own eyesight. After they left low earth orbit, they saw phantom flashes of light when they closed their eyes.

If time and space are different forms of the same thing, and space is possibly infinite, is time infinite too?

The post you're replying to needs some clarification. It isn't that the universe isn't logical. It's that the universe was invented to make sense of ourselves. Everything that we know about the universe was formed in our mind. That's where the logic happens. Without the mind, there would be no definition of anything.

Of course, only minds can have concepts or access to any information whatsoever. But we didn't invent or define the laws of physics or the rules of logic, we simply discovered approximations of them to lesser or greater degrees of accuracy.

Time remains as it will be currently occuring in its form and matter in the presence under which we have sense in understanding it through our correlation with what we perceive in this istance of moments amounted, though it will always be so in a way of saying perhaps , its difficult to say properly

Why should we spend taxpayer money on what amounts to cool pictures and slightly-better informed sci-fi?

Jesus I don't know why I bothered. You are just dumb.
If you understood the evolutionary relationship between the major orders of chordates (fish, reptiles, avians, mammals) you would know that from a thermodynamic, interactive and reproductive perspective what I am saying is exactly true. Everything we do depends on cooperation. If you were just you by your self trying to get people to slave away for your 'glory' you would be dead within the day child.
It would absolutely positively cost more energy to send a plane up every day for 10 years than to send 1 satellite up that stays in orbit for 10 years, by a huge margin. Do you really think closeness to the ground has anything to do with our ability to photograph it in detail? We have telescopes that can see TO THE EDGE OF THE VISIBLE UNIVERSE.
Bitch tell me to back the fuck off and back it up with more hate inspired uneducated bullshit if I saw you in real life I would snap you like a twig, motherfucker I don't know why I thought you wanted to be reasonable, I guess I'm the ass here. I should have just called you on being the troll you are and left it at that.

You are as aggravating as my friend who once unironically insisted the Earth is our entire universe and every thing seemingly beyond is an illusion because quote "I thought about it for a really long time man"

I'll tell you the same thing I told him. pic related. Science means I don't have to believe in shit, I can just know, and I know that aint right.

This thread is actually well timed as NASA recently published its 2016 issue of Spinoff: https://spinoff.nasa.gov/Spinoff2016/toc_2016.html

It may be a good read for folks who don't see the value in pure research.

Also there's the patent portfolio, if you're interested: http://technology.nasa.gov/patents

Because of the sheer amount of energy and resources out there we can harness to drastically improve life here on Earth. Or we can just sit here and stagnate, eventually running out of the raw materials needed to advance or support our technology. Thereby taking a massive technological step backwards at some point in the future.

Also, survival and the dominance of the Human Species. We're fragile asf here on Earth. One errant asteroid/comet/gamma ray burst/black hole/star/planetoid and it's all over. And that's just the threats from space. Nevermind the countless threats to our species here on Earth, including ourselves.

TL;DR - Because it is not wise to shit where you eat. Nor to have all your eggs in one basket.

Check it. NASA wants to send a submarine to Titan to go look for critters there.

Please please let this happen.

>And saying your very finely tuned argument about why we should only care about it your specific way is 'actual science' while any other interpretation is ignoring the universe as 'stochastic' is well just intellectual bullying imo.

Uh ok. I didn't argue that we should look at the issue in my way only. I just pointed out that in science you need more than two data points to make solid predictions.

If you flip a coin twice and you get two heads, then flip it 10 times and get 7 heads, you can assume it's loaded in favor of heads and predict it's gonna give you more heads than tails no matter how often you flip it. However that assumption is completely wrong, the probability is still 50%. It just so happened that the few times you flipped the coin, you got a majority of heads. Had you flipped it 100 times you'd get closer to a 50/50 spread of results.

It's the same way with life. If our solar system contains two independent origins of life, we can assume all we want about the general incidence of life in the universe, but until we actually go to new systems we're still in the dark about how common it actually is.

>If our solar system contains two independent origins of life
There's also a question of panspermia within solar systems.
Maybe life was sprayed all over the solar system from planets that cooled sooner, if life on Titan seems related to earth-life, then we'd assume the reason life formed on earth so soon after it cooled is that it had formed on mars/a moon a million years earlier.

If we assume it's that, then we don't get any data points for biogenesis.

This is a pop-sci article I know, but the work it's based on seem very interesting and def relevant to this thread.

http://ringrom.ga/2016/09/22/life-not-as-we-know-it-possible-on-saturns-moon-titan/

Essentially a team of chemical engineers and astronomers have theorized a template for an enclosed cell capable of thriving in liquid methane/ethane, rather than water as is the case for the lipid-based life on Earth. Pretty interesting read, and it offers insight into possible life on what we consider horribly cold worlds.
