  • The bad flooding is because of how steep those areas are. Down in Florida, water takes a while to make its way into the creeks, streams, and rivers. The areas with the most extreme flooding is because entire mountainsides worth of rainfall drains in the span of a couple days.

    Eastern TN and western NC also had a ton of rainfall from thunderstorms just before Helene so the ground was already saturated. For reference check out this rain gauge in Asheville.

    https://waterdata.usgs.gov/monitoring-location/353312082355545/#parameterCode=00045&period=P7D&showMedian=false

    The rain from Helene didn’t really get to Western NC until the early hours of Friday the 27th. That gauge was already at 10 inches by that time. So really the storm before Helene brought more rain than Helene did. Either the thunderstorm or Helene alone would have been moderate, but manageable flash floods, but the two back to back was insane.

    The trouble is that a fad doesn’t have to be functional to be used by short-sighted trend chasers as a justification to make cuts. How many jobs did we see outsourced to India in a way that didn’t even come close to matching the quality of the people laid off? The people who make the decision to replace jobs with ai systems will loudly declare success and move on to their next role before the long-term consequences are fully realized.


  • Black holes don’t swallow everything around them for the same reason that the sun hasn’t swallowed all the planets. Outside of the event horizon, gravity still works normally and the fact that it’s a singularity doesn’t really matter. Gravitational capture usually involves multiple objects, because the trajectory has to get nudged for a collision to happen. A gaseous body collects mass at a faster rate than a black hole with the same mass.

    As long as the earth-sun orbit stays close to 1 au, then ejecting the moon into it’s own solar orbit wouldn’t necessarily be world ending. There would probably be some aquatic life extinctions from the loss of tides, and some nocturnal species might be affected by the change in light levels.

    The sun diameter is 1.4 million kilometers, and the earth-moon orbital radius is 0.38 million kilometers. So trying stick the sun between the earth and moon at the current orbital radius just makes the sun 1/333000th more massive.
