  • And many of us think they aren’t.

    The headline isn’t stupid in a vacuum, but it implies things that are demonstrably false and others that are just known fact.

    My takeaway was “why were there vacant seats?” And neither the headline nor the article cover that.

    The government is tasked with keeping those seats filled. The reason to keep them vacant is usually to concentrate senate power in a smaller number of individuals who are easier to influence. Filling those seats is a GOOD thing to prevent abuse of elected power, unless there’s provable evidence that the senate is being stacked with hyperpartisan people in a manner that skews to a particular political ideology. That doesn’t appear to be happening here.



  • Think of it this way: imagine a slowly moving stream. Anything in the stream will move along with the current and from its perspective will be “stationary” in the current, right?

    But then think about the surface of the stream: the air above it isn’t moving, so the stream surface is rubbing along the air interface, creating drag. This means that the air is going to end up moving a little bit in the direction of the stream, and the stream surface is going to be moving a bit slower than the main body of water.

    Wrap that in a circle, and that’s what the layers of the earth’s atmosphere are like. So a skydiver is “diving” in an atmosphere that is relatively (but not completely) stationary above a certain spot on the earth.

    For an experiment you can try yourself, fill a bucket with water, and then spin around in a circle holding the bucket. All the water stays in the bucket instead of sloshing out one side due to the bucket moving through space. This is a combination of inertia and force acting on the contents of the bucket.

    The earth is big enough to have a gravitational force strong enough to resist shear) the rubbing at the interface), and there’s nothing really out there in space for it to rub against. So the air is more impacted by the gravity of the moon and the heat of the sun than it is by friction against space or inertia overcoming gravity to send things flying off the earth at an angle.






  • City name would be helpful. I presume you have no access to money? No bank account in your name etc? Most towns and cities have a place to crash and get at least one meal a day. Salvation Army usually has something if there’s nothing else.

    Once we know the city, hopefully someone on here can be of more tangible help.
