  • In that case, given that a rose would need to have a certain minimum angular size to be recognisably a rose, and it would have to be outside the atmosphere to not be a guarantee of the imminent cessation of my existence, that would have to be a VERY big rose, which doesn’t bode well for life on earth if it’s approaching at relativistic speeds. Or are you suggesting that it’s a galactic - scale rose, and we’ve got a few million years before it obliterates the Milky Way?


  • So, what I’m taking away from this is that, if I ever see a blue rose, it’s already too late, and the object moving at relativistic speeds toward me has already probably ignited a thermonuclear reaction in the air around it, but the light from the fusion bomb before me has not yet reached me?








  • In case it was not your intent to point this out with sarcasm, for anyone reading:

    1. not all forests are created equal: new growth forests are simply not as good at long-term burial of carbon.

    2. carbon sinks only work so long as the carbon stays sunk, so if a tree dies and rots before it’s buried, all of that carbon just goes back to the atmosphere, except a lot of it is now methane, which is MANY times worse than CO2.

    3. this means that it is possible for a poorly - managed tree to actually be an effective carbon source for the purpose of greenhouse gas emissions, rather than a sink, since a single molecule of methane can do the damage of a hundred molecules of carbon dioxide.

    4. the largest carbon sink on earth is not the forests, but the ocean, and that carbon only really has two ways out: back into the atmosphere, or buried at the bottom in the calcareous ooze. Now if you really want to understand how fucked we are, read up on the following:

    • Carbonate Compensation Depth (see how it relates to the amount of calcareous ooze being buried in the ocean)
    • Methane Clathrate Hydrate
    • Permafrost Methane





  • The pillaging was actually only a very small part. The vast majority of going Viking was pure trade or, when conquest was on the table, colonization. That’s how you get the Rus Vikings. When a bunch of pagans see unguarded temples, though, all filled with gold, and their gods would be pleased by the offering of such things? Yeah, they’re going to pillage. It was often far easier to just trade with the people already there, and so they did. The idea that they’re all there to make blood-eagles and die in glorious battle is ridiculous. They had a complex civilisation that set up many of the mediaeval trade routes throughout Europe and into the middle east.





  • Well, given that Ra kind of is the sun, they wouldn’t be wrong in that assumption. Though that’s not actually what they believed. They believed that Nut was the sky above them, and Geb the unmoving ground beneath, and that they delineated creation. It wasn’t until the Greek Eratosthenes’ experiment that the idea of a round earth was proven, though it had been suggested philosophically for a couple hundred years before him. The idea of the earth actually moving was also proposed by Aristarchus near the same time as Eratosthenes’ experiment, but wouldn’t gain wide acceptance, let alone be proven, until the time of Copernicus, Brahe and Kepler.
