    Fun fact this is why the chance of aliens visiting us here on earth is basically 0.

    You can’t use earth scale thinking, that’s how big space is.

    But that is earth scale thinking. You know, in a “things heavier than air can’t fly” way.

      It’s more of a “the speed of light is the cosmic speed limit” way of thinking. If you feel aliens are visiting earth you do you.

        That’s what i meant. Even our civilization, with our limited understanding of physics, can think of theoretical workarounds.

        Dunno if aliens are on earth. But that argument against it, is only guesstimating.

          Fair. But that’s not really earth scale thinking in my book. It’s more our best understanding based on what we know.

          I know of these theoretical work arounds. They’re more mathematical models that say if such a thing as negative mass exists, then we might be able to go faster than the speed of light. Issue is that the model does nothing to show that negative mass exists.

          That and everything we know shows that it does not exist. If it did I would be incredibly happy. It’s just wishful hoping at this point though. We don’t even have a model or theory that shows how negative mass could exist. We only have theories that show what could happen if it did exist.

          It’s like saying hm we know how F=m*a works. What could happen if we set m to a negative number? Yah in the math we can but that does not mean we can in reality.
