    It’s not difficult. Gravity is like magnetism for things that aren’t magnetic.

    “The nature of this elementary particle is best expressed through these thirty equations.”

    “Ok, ok, but what do those actually mean in reality?”

    “Reality?”

    Everyone always asks what is gravity.

    No one ever asks how is gravity.

    Poor gravity, always helping us keep our shit together but no one ever truly understands the weight on gravities shoulder.

      I’m in geoscience. Physicists are nerds. Touch grass, ya dweebs. We wear hiking clothes on campus and we aren’t going on fieldwork until July. It’s called dedication.

    Genuinely we can’t tell what it is. We once thought it was just a normal pull due to mass until Einstein proved us wrong during a solar eclipse where we could see stars that shouldn’t be visible from our current position in orbit. Then we get into how it works, WHICH THERE IS NO TELLING AS THERE ARE TO MANY GOD DAMNED VARIABLES INVOLVED.

      You’re fucking with me, right?

      Stars were visible that shouldn’t have been visible?

      What am I missing?

        Stars that were behind the sun (within the radius of the sun, geometrically speaking) were visible due to gravitational lensing

            It isn’t directly analogous because one is gravitational and the other is not, but if you’ve ever watched a ship sail beyond the horizon, sometimes you can see a reflection of the sail after it is no longer in direct sight, because the way that light can reflect around the curvature of the earth. It’s a pretty crazy phenomenon.

            https://en.m.wikipedia.org/wiki/Mirage#Superior_mirage

            In the case of the OP, as light from distant stars approach the sun, some of their light that may normally have passed to the side of the sun and beyond the earth, thus rendering them invisible, are instead ‘bent’ back towards the earth by the sun’s gravitational well. But since the sun is so luminous we normally cannot see those stars. If the sun were somehow dark we would see a collection of tiny, distorted stars around the perimeter of it.

            To metaphorize: imagine a ball rolling straight from a point directly in front of you, but at an angle such that it won’t roll to you. Now imagine a dip in the ground, not deep enough to cause it to fall in and not escape, but enough to cause the ball to curve as it rolls, sending it to you instead. The sun acts in a similar manner on light.

      You can basically half American salary numbers because we have to pay for a lot of stuff that Europeans usually don’t need to pay for. $57k in America is struggling if you live in a city. Anything below $40k is one car repair away from being financially ruined.

          We don’t have public transit, so we need cars… It’s part of what makes us poor…

          You are correct. We are forced to have them though. There’s no mass transit and everything is two hours away on foot. Most new cars now are $40k unless you get like a base Sentra but the median income is only $60k.

    Perfect use of this format. “I don’t know” is the foundation of wisdom. See: reddit where too many think they know.

      See: reddit literally any message board where members of the general populace can freely participate where too many think they know.
