  • War! What is it good for?

  • Also- The Gulf of Tonkin incident used as a pretext for the USA going into Vietnam was a fabrication.

    To be clear, there had been a scuffle involving US ships on Aug 2nd, 1964 - but it was not a deliberate attack by the North Vietnamese.

    The supposed attack on Aug 4th did not happen.

  • We created an incredibly efficient method of transport and then most of us abandoned it

  • I think the math checks out for this graph.

    If a human on a bicycle consumes 0.15 calories per gram per kilometer, then a 100 kg person would be:

    100000g x 0.15 calories = 15,000 calories = 15kcal

    I'm guessing these numbers are for a racing bike on a flat stretch of smooth road where you don't need to brake or accelerate.

  • ...is this retro?

  • Depending on how pedantic you want to be, that is for the United States release. The Famicom was released summer 1983 in Japan and the NES is generally considered the localized version for North America.

    Jump

  • You're a generation off: It's more retro now than the NES (US release) was when the 360 came out. We crossed that threshold about a month ago.

  • My dude, how does any of that follow from what I said?

    I'm saying we have to work together to enact the changes we want, and that requires being dependent on other people's specializations. Banding together is literally the biggest strength of our species.

  • Fierce independence is how we got into this mess, and allows exploitation by organized power-hungry groups.

    People need to cooperate in egalitarian collectives to achieve goals and resist exploitation.

    Now boss makes a thousandAnd gives us a centWhile he's got employeesWho can't pay the rent.

    When boss makes a millionAnd the workers make jackThat's when we strikeAnd take our lives back.

  • I have had Gros Michel bananas. They do not taste like banana candy, although weirdly they do smell like the candy much more strongly than the Cavendish.

  • It's more complicated in ways that aren't intuitive.

    Yes, at first glance, it appears that everything would continue to collapse down to a singularity. But a singularity is literally a failure of our model of physics. It's like dividing by zero- the result is nonsense. It's not an actual object.

    From our perspective, time is stopped at the event horizon of a black hole. The singularity never forms because there isn't time for that to happen. If you fell into a black hole, would a singularity form as you are crossing the event-horizon? Maybe. Maybe Hawking Radiation is a thing and you're cooked by a wall of radiation as the collapsing object literally evaporates beneath you.

    Keep in mind that high densities are needed for stellar black holes to form. An event horizon would form around the solar system if it was filled with air- and yes, there are black holes of this size.

  • well?

    Jump

  • I think it's a combination of at least three things.

    Cosmic Microwave Background radiation gives us a pretty good idea of the energy/mass density in the universe at a fixed point and age of the universe. If you take the densities estimated from the CMB and multiply it by the estimated size of the universe at the time the CMB (380k years after the Big Bang), then you get the total mass.

    Second, we can just look for what we can see. I think there have been large-scale surveys done to estimate total mass/energy in the universe.

    The third estimate has to do with something called 'critical mass' - we observe the overall 'curve' of space to be very close to flat. I'm talking the geometry of space; two parallel rays of light do not ever cross or diverge. For this to happen, there needs to be a certain average density of mass.

    Wikipedia has the mass of the observable universe listed as 1.5×1053 kg, although this can go up to 1060 kg at the higher ends.

    If we plug the Wikipedia numbers into the Schwartzchild radius formula: r = (2GM) / (c^2)

    Where G is the gravitational constant, M is our mass, and c is the speed of light:

    r = (2 * 6.67408 * 10-11 m3 kg-1 s-2 * 1.5*1053 kg) / (299792458 m/s)2

    r = 2 * 1043 m3 s-2 / 8.988 * 1016 m2/s2

    r = 2.225×10^26 meters

    r = 23.52 billion light years

    Wikipedia lists the radius of the observable universe as 46.5 billion light years.

    So... given the Wikipedia numbers, the universe would need to be half the size it is now to be a black hole. At these scales, being within an order of magnitude is... fine.

    If we bump up the estimate of mass to only 3x10^53 kg, then the Schwartzchild radius equals the size of the observable universe.

    So it's within the margins of error of our current estimates that the Schwartzchild radius of our universe would be the current size of our universe.

  • well?

    Jump

  • If you take all the mass in our universe and run it through the Schwarzschild equation, you get a black hole with about the same radius as our observable universe.

    Things don't need to be tightly packed to be a black hole, there just needs to be enough stuff in an area.
