The man.

Scroll up that's exactly what I said. Perhaps you don't live in the USA but here the majority of people are nutters who deny basic science facts and instead believe wholeheartedly that their made up fantasy is what the world is. I need to suppress the urge to break the nose of people who say its hubris to think humans can change gods creation - these are the same nutjobs who don't believe in evolution (as if that affects the truth of it). At least this is a step in getting those extremely stupid people to change their tune, if only a little.

Maybe I'm missing something but who actually thinks we can load a rocket and fly off to another planet? Besides the mars one people i mean.

Whoever thinks the pope is trying to pick sides in a political debate is either genuinely insane or has trouble forming simple logical concepts. Because on the scientific overall concept it's not even a debate. The best methods for combating climate change though, are still only scientific. Politics dosent even enter in until you try to implement those methods.

Go ahead and mod me down but I'm really sick and tired of people thinking what they believe makes a crap in a biscuits difference to reality. Even though the popes statement may be lacking its a great step to get hundreds of millions of stupid people to start acting responsibly and be aware of the issue. It's just so ironic that it is a belief in faith, with no foundation in factual reality, that brings awareness to the factual reality we as a species are facing.

5g will actually be around 2-3Gbps in every day use then. I wonder when companies in the USA will pull their heads outta their asses and we will have an infrastructure nearly as good as the top half of developed countries.

I wont be satisfied until i see my own tablet displaying google earth real time in the app doing one of those infinite recursion effects.

Actually that's the entire point. Sure movies have it dead wrong. But the general idea is to gently boil off material over the entire side giving it a small kick. Several would be needed in all likelihood and hopefully at least one orbit ahead of time. At the very least several AU of distance would be needed.

There are much better ways of handling it though and the insignificant chance of a deadly object we can deflect with that method is likely dwarfed with the chance of incompetence and mishandling.

Simply drilling into it and fragmenting it would be disastrous at close range, perhaps even makng it more deadly and is as likely to completely reduce it to dust as exploding a whale with tons of dynamite.

Easily as in we just keep what we are doing at the pace we are doing it. As you may be aware housing prices aren't exactly sky high all over and as far as I have seen there is no genuine shortage only social and political issues. Right now we are close to being able to pack 30+ people in per square meter in 100+ floor buildings. In 200 years it's likely 500 floor buildings will be possible. In any event there is no space shortage whatsoever.

The whole premise is bull.

There is more than enough food to feed everyone. The problem is mostly just politics such as feeding a SUV enough corn to feed a family of 10 for a day to simply drive to the mall and back or letting relief supplies get resold on the black market.
space? Are you kidding me? Huge sections of the earth are completely barren, with existing technology the USA could easily accommodate a thousand or even a million times its population and not run out. Maybe some tiny countries have issues but not the world in general. We aren't even building floating cities yet.

medicine mostly has the same issue as food and the complex relationship between patents and rights and patients who need the medicine. Some is genuinely expensive and difficult to produce. But even today street bums get better medical care than kings just 300 years ago. It will only improve.

All the earth needs to support far far more humans is cheap clean energy and automation. Nuclear fusion, cheap solar and similar technologies will likely be a reality before humans living forever. Same with completely autonomous and self contained manufacturing. Combine the two and you could create hydroponic fields thousands of layers deep tended by robots and powered by light from a fusion reactor. You could build complex mega cities capable of housing a billion people.

This is the second article today. Typically authors of blogs and news stories get one exposure on slashdot per million years. It's quite rare for even two exposures. Imagine how the Slashdotter community would be rocked if four Ethan articles were posted within a single day!

The cmb is simply the first light that was able to freely travel through space. There is no actual 'edge' but there is always the apparent virtual edge beyond which you cannot see. It's easiest to think of it as space being infinite in size but finite in age. Light needs to travel to your eye to see so the farthest you can see is simply the age of the universe x the speed of light. As the universe cooled right after the Big Bang, initially light could not directly pass through all the hot plasma, only after it cooled and became transparent to visible light did light spread out in significant amounts. The heavily red shifted version of this light is the cmb we see today. Your own two eyes see a slightly different virtual 'edge' as every point in the universe looks as if it is the center.

It took about 380k years for the universe to become transparent to light neutrinos pass through ionized material easily and the surface of last scattering is nearly as old as the Big Bang. It's a very old concept but has been researched lately as each kind of neutrino would have a slightly different background. The article is just random click bait there is nothing new or interesting about it really.

It would have to be a good captcha. I coded a vision to text function myself for another game i was botting on, it's actually not hard to bypass. It did piss people off when they reported me and I passed, sometimes when I came back i saw upwards of 10 successful passes on my log.

Woah woah woah. We are already talking about automated semi trailers why not go to the next logical step and assume a self replicating robot drone army? Why starve or kill the old fashion way when you can live on paradise island while the rest of the world burns terminator style in preparation for the construction robots to turn it into paradise? At the very least you could force them to do whatever you wanted. At no point in history could the 1% actually do away with the rest of the humans. Now with tech not only is this possible it may become preferable as they see it.

If musk wanted to make billions off spaceX he should have been sending cats to mars. Because paid access to video feed of cats doing low grav antics would break the internet and his bank account.

Matter antimatter annihilation is the reason. During the early stages of the Big Bang, matter and antimatter were created in nearly equal amounts. Electrons and positrons, protons and antiprotons, etc. They annihilate on contact and produce two gamma rays. But due to expansion of the universe the photons lose energy as they are stretched in transit and lose the ability to transform back into particles. Today they are very low energy indeed and roughly one thousand times less energetic.

Thus they are very numerous but make up only a small fraction of the energy in the universe. The ratio of these photons to normal matter essentially is the symmetry breaking that tipped the balance in favor of matter throughout the visible universe. No one knows exactly why it's this ratio, a successful theory could net someone a novel prize.
