I was hoping this was about the infrastructure and systems around collecting human garbage in the modern world.

Anyone have any details on recent developments in the field?

For example:

  Reclaiming raw materials from landfills
  Machines/robots that can sort recyclable materials from a heap of mixed garbage.
  Better insulated landfills

In the area in Stockholm, Sweden where I live we throw "all" garbage (we of course separate glassware, metal, paper, electronics first) in the same bin, but food waste in green bags. I don't know if it's robots that does the final sorting but I would believe so. Less than 1% of household trash ends up in landfills here.

Maybe these open web apps should be built on the... open web?

I think it means that it's expanding and traveling in the opposite direction of us. If we start at the same spot, then both travel in opposite directions at 1 mile/hour, at the end of an hour we will be 2 miles away from each other.

There is not really a center, galaxies are more like raisins in a rising bread. They all move away from each other with the same relative speeds. At least... Any physicists here to tell me whether or not space-time density get less closer to the edge? I mean... Is there an Edge?

There is no edge. It defies the normal way of thinking but every point in the universe is also the center of the universe. The Big Bang happened at every point and space-time is expanding at every point.

There could be an edge, but it's definitely not within the distance we can see out. The main mind-bender is that there's no need for an edge.

Well, not really. The distance we can see out is measured in time and we can very nearly see the Big Bang. We can observe the Universe's Recombination event and it is in every direction we look as the Cosmic Microwave Background. This happened everywhere in existence.

If there is an edge to the Universe it is in the fourth dimension when the Universe was a singularity.

Earned $5 laughing at this comment.

No they don't.

Do it! I've seen videos floating around E.g. [0] that are as simple as a giant fan that sucks in mosquitoes.

Aedes aegypti are an invasive species to the U.S. [0] so there's little evidence that they would greatly negatively affect the ecosystem if they were to suddenly be eradicated.
