>The Sun is in the midst of an unusual sunspot minimum, lasting far longer and with a higher percentage of spotless days than normal; since May 2008.
>The Sun is measurably dimming; its output has dropped 0.02% at visible wavelengths and 6% at EUV wavelengths in comparison with the levels at the last solar minimum.
>Over the last two decades, the solar wind's speed has dropped by 3%, its temperature by 13%, and its density by 20%.
>The Sun's magnetic field is at less than half strength compared to the minimum of 22 years ago. The entire heliosphere, which fills the Solar System, has shrunk as a result, thereby increasing the level of cosmic radiation striking the Earth and its atmosphere.

All stars die eventually.
Throughout a stars lifetime they get hotter. The sun is has greatly increased in luminosity during the last few billion years or so.

Would you want to thaw out a caveman who has been frozen for thousands of years? Compared to the people of the future it will probably be stupid and violent and uncultured.

You are far more likely to be destroyed than re-animated, even if your cryogenic freezing was successful and you survived the process.

> You still all think that is funny?

Yes, of course I do. It's the fucking sun. I can't do anything about it. Nothing Humanity could do about it, would make any fucking difference. You could toss Venus into the sun, and it wouldn't make any fucking difference at all, except some prominences would develop and the composition of the solar wind would change slightly for a while.

Humans are at the total mercy of the sun. Our only proper response (knowing that) is to become a spacefaring species. But we're not doing that. No, we're only planning on FUCKING EACH OTHER OVER so that a minority can get every richer, before population collapse and war occur.

One million years from now, there won't be any Humans. The only evidence of Humanity will be from air and soil samples taken from the Earth showing interesting traces of radioactivity. DNA samples from the surviving flora might show interesting examples of unnatural selection. But that's it.

One million years from now, even Humanity's radio signals will have propagated away, diffuse beyond all recovery.

Even Mt Rushmore will become destroyed from erosion and the effects of continental drift.

Humans represent a thin veneer of technical intelligence over a roaring and massive core of violent animalistic behavior motivations. We don't have what it takes to survive as spacefarers. We can't put aside our Violent Simian nature long enough to achieve an interplanetary infrastructure, much less an interstellar one.

You underestimate how much we've progressed, culturally, as a species. For instance, ever since civilization has been around we've been destroying the environment. Whole societies (eg Easter Island, Greenland) have been destroyed as a result of environmental degradation. Right now is the first time in history that mass consciousness has become aware of environmental problems and willing to do something against it (can't speak about politicians though).

Imagine a society where people were educated from a young age on how to be good, treat others well, think and learn independently, be skeptical, etc.

We can be a space-faring race if we wish.

If we're already talking about the sun I have a question:

How come pictures of the sun are always orange?
In real life the sun is all colors/white after all.

Agreed. We humans are over-adapted for the Earth environment. However, we are making great technological progress towards creating our cybernetic children. They will be hardened against radiation, vacuum, and deep time, stepping out amongst the stars and leaving us to our retirement.

And like all other times in history, what's being done is only being done for ECONOMIC reasons. Notice well what the West did: It EXPORTED pollution. If the Second and Third Worlds didn't exist for our exporting of industries, we'd have kept them here, and you'd still see the rivers around Chicago and Cleveland on fire.

We already do that. Most people revert back to Violent Simians anyway. Because that's what we are, asscake: VIOLENT SIMIANS. And we're going to tear the holy living FUCK out of each other in our Resource Wars, during the Long Emergency of Petroleum Starvation.

> We can be a space-faring race if we wish.

No, we can't. I already explained that our violent natures of competition will over-ride all that nonsense. The Space Age was really only a thin veneer of technical accomplishment that supported the military, just like our nuclear energy industry only existed to breed more plutonium for the military. EVERYTHING we do is calculated to advance out means, towards prosecuting the successor the Resource Wars, which I call the LAST WAR. When the LW rolls in, the use of nuclear, biological and chemical weaponry will become unrestrained. Other than starvation, we'll have to kill off at least 5 billion people, since they are too hungry and dangerous therefore to keep around.

And that will destroy Human civilization, for good.

We're really no smarter than our simian ancestors. We feed, fuck and fight. All national policies on the world stage support that.

[Anonymous No.4681829]

Don't try to argue with Violent Simians guy, guys. He'll just keep going on about peak oil and resource wars that haven't happened until the sun burns out.

Oh, and despite the sun's total lifespan of ~9 billion years, and being about 4.5 billion years old already, earth will be uninhabitable entirely in about 1 billion years, when the sun kicks into overdrive and gets extremely hot as it starts to fuse heavier and heavier elements.

You're missing the point. Obviously, public policy has been enacted in the interests of Corporate America. People are starting to realize that our political system doesn't represent the interests of the masses, it only represents the interests of a very small but very wealthy sector of the population. It's plausible -- I'd say likely -- that a revolution takes place in the future, a revolution that creates a democratic society (perhaps in the spirit of anarcho-syndicalism) Then, *actual* measures to protect the environment -- supported by a majority of the population -- can be implemented.

Have you ever been to school? You're not taught how to think independently to pursue a self-directed path of learning. You're taught how to be subservient to authority.

Again, that assumes that our hierarchical social organization will persist. It most certainly will not, either because it will self-destruct, or because the citizens of our planet will revolt and a glorious anarchist utopia will be created.

There have been extended minima in the past and nothing bad happened, it gets cold in Europe but not because of a drop in output. We have significant evidence that the solar wind varies a lot, as does the output and magnetic field. The drops in output are totally normal for solar minimum. Your citations are over 2 years old, are well into a respectable maximum mow.
The sunspot cycle is never a perfect clock it varies by years.

>sun's magnetic field has dropped over 50% in the last 22 years
Am I the only person wondering why nobody is making a big deal about this? For a star like the sun, ANYTHING noticable happening in such a short span of time is equivalent to it instantly disappearing relative to its cosmic age... why all of a sudden has it decided to kick the magnetic bucket?

also... we have been having wierd weather and animal shit happening more and more lately... with all this climate change shiz wouldn't it be prudent to find out why the THING THAT GIVES US 99% OF OUR ENERGY ON THIS PLANET isn't being normal?

First off OP didn't cite it and secondly it is not unusual. Don't jump to conclusions because something sounds off to you. The sun can vary in x-ray output by 100,000 times in minutes, it does not have to do everything slowly.

>The first sign that the prediction was wrong came when 2008 turned out to be even calmer than expected. That year, the sun was spot-free 73 per cent of the time, an extreme dip even for a solar minimum. Only the minimum of 1913 was more pronounced, with 85 per cent of that year clear.
