  1. Re:Are there more or do we just find more? on Asteroid Whizzing By Earth 6 Times Closer Than the Moon (cnet.com) · · Score: 1

    Such small asteroids hitting the Earth are a lot more common than once every 10000 years. Many will go unnoticed.
    The Chelyabinsk meteor 2013 was about 20 metres, which is already larger than that. And the Tunguska event 1908 was a 60 to 190 metres object. The smaller the object the more common they are.

    As with all complex software, and AI is an extremely complex one, it becomes difficult to exclude security holes. So the problem is that someone else might control your AI battle machines and turn them against you. It won't be the AI itself.

    It is not logical as long as new coal power plants are built. It is only logical if you ignore where the additional power comes from, or if your place relies on renewable energy.

    A large part of their electricity is produced in coal power plants, which don't even have sufficient filtering for soothe and sulfur oxide. An electric car running from such power plants is way worse for the local and global environment than a petrol car. More CO2, lots of additional SO2 and soothe.
    They should focus on these power plants and on their kitchen fireplaces first.

  6. Maybe intentional overbooking is forbidden. But several airlines sell tickets that allow you to fly anytime without prior notice.
    So, how does that work, if several people with such tickets decide to take a fully booked flight? Someone else will be told that the flight is overbooked, and the people with their expensive flexible tickets get what they want.

    As far as I know the problem with asbestos is that the fibres are too big for the immune cells to swallow them. They stay in place and cause a constant inflammation.

    I mean, I don't know if climate research is done properly or not. I am used to large discrepancies between press releases and actual research, so I know that I can't tell anything from the news stories. What I read on the news does not convince me though.

    I think this effect of tectonic plates swimming on the molten lava below could completely eliminate the effect of melting of ice on the sea level, which would explain why it is not seen in measurements.
    And I have a similar problem with the temperature rise simulations. They don't include any cloud formation in the simulation. They say that if because they are not sure if the effect is positive or negative.
    I think it is quite obvious that clouds have a very strong effect on temperature, and that their formation changes with the temperature. I wonder if they are really unable to simulate these, or if they don't want to because the clouds could reduce the warming effect too much.

  11. Re:We're so screwed on Rapid Rise In Methane Emissions In 10 Years Surprises Scientists (theguardian.com) · · Score: 1

    No. This story itself is not so bad, but I also want to read stories on processes that weaken the effect. For the actual numbers we can only rely on the scientists. I want to see that they actually see the whole picture, and not do a simulation that results only from a search for problems.
    For example, when looking into sea-level rise I noticed that the weight of the water from molten ice will increase the pressure on coeanic plates. This will move the oceanic plates closer to the core, while it will lift up the continental plates at the same time. This reduces the ocean level rise.
    When searching for this I found a publication where this was actually simulated, from around 1985. I don't know if this effect is taken into count nowadays, or if it was forgotten about.

    I don't really want someone to say that everything is fine. I want to feel like I get a complete picture. And it is obvious tbat we hear pretty much only one side of the story, only the enhancing effects.
    And I have read the scary predictions of a methane runaway too. But I don't see that much of it in the official reports, so I don't believe that the first reports were accurate. See, you can't just take up everything that fits your viewpoint or fears and take it for granted. You always have to question things to find the truth, and not end up at some extreme viewpoint.

    That "runaway" process only releases the Methane that was captured since the last time that the temperatures were that high.
    Also, complex systems not only contain some runaway processes (which always have a limit), but also processes that reduce the changes. I feel like we don't hear enough about such processes. The media and everyone else seems to prefer to spread panic to get the attention of their readers.

    Following the links shows that he was accused of spoofing, which is the creation of fake orders to manipulate stock prices.
    After some gooling, the problem for me is: The 2010 flash crash occured on May 6, 2010, while the Dodd–Frank Wall Street Reform and Consumer Protection Act, which makes spoofing illegal, only came into effect on July 21, 2010. And it is a US law, which does not have an effect on the extradition from UK.

  16. It is a matter of what you are used to.
    You need to know a lot more numbers in the imperial system than in the metric system. In metric everything is just 10 or 1000. And how often do you need a liter 8 ways? Well, often enough that I know that it is 125ml, and that there are marks for this on measuring devices, but the point is that it is really not a problem.
    And we still measure times and dates the same day, not in kiloseconds or whatever. This is not specific to the imperial system.

    What's the problem with tidal locking though?
    I once read that the backside would be so cold that the atmosphere condenses there. This is not what happens on Venus though. The dense atmosphere evenly distributes the heat around the whole planet, making the temperature nearly the same everywhere.
    Thinking about Earth I would expect that a constant pattern of air streams could form which transfers the heat between hot to cold areas.

    Teleporting is a crazy science fiction idea, but the small assembler being sent out is what I also think is the way it will go. In the future we can send small probes that will bring life to new worlds. We can design intelligent lifeforms that are living there, and are a kind of the children of our species. We can send all information that is useful. These new lifeforms will grow out of single cells with the help of small machines built for that.
    But sending whole people to other stars is just extremely difficult and not really worth it.

    In your country land ownership includes all the mining rights? Wow, seems crazy. It messages no sense to do that in the first place. Though changing these rights afterwards will create trouble.

  20. The greenhouse gas forming from flooding the land is a one-time effect after the flooding. And the organic material that is deposited from the river would have went into the ocean otherwise, where it would also rot and form greenhouse gases. The reservoirs just change the location of this greenhouse gas generation, not the amount.

    I agree. They see that cancer develops only when too many mutations build up in individual cells, which causes all the safety mechanisms to fail. So many mechanisms have evolved to stop these cells that are out of control. And they conclude that evolution wants them to kill us when they are out of control?
    This misses so many points. Though I am too lazy to check if TFA explains their thought process.

    It is not certain if it is possible to travel any faster than we do already though. Science fiction is fiction, don't forget. Also, space travel requires large amounts of energy. I think we can do it now because the technological advancement have us an abundance of available resources. This is temporary though, resources will run out, and humanity will fall back into a fight for survival. This will make space travel a crazy unaffordable luxury.

    For some reason they need humans to produce a certain substance. Not just a bunch of cells, not something without a brain. No, it must be a complete, awake and conscious human, with a machine keeping the brain busy.
    This is only good for a movie story. In reality it is a very inefficient solution in any case.
