  • The net result is that I have transmitted a message into my own past.

    Yes this is literally the explanation that comes from every physicist and science explainer I have come across. The problem I have is the how. I do not understand how a message sent real time, as in at the same time on two different planets vast distances away, can go back in time “somehow”. Like, I get that the actual answer is ultimately “the math says so” but I cannot adequately wrap my head around the concept.



  • Every time I read about or listen to someone’s explanation of why faster than light travel is completely impossible it always makes no sense to me.

    I have tried to understand it more times than I can count but every explanation seems to revolve around faster than light travel breaking causality because of information traveling back in time due to relativity. Granted it’s always physicists who are explaining why faster than light is impossible and I’m a complete layman so there may be a translation issue there.

    Okay I hate Bill Gates as much as anybody because he is a greedy scum sucking billionaire with extreme self-interest, but common core didn’t fail because it was a bad idea. Setting a common standard for all of education is not a bad thing. The problem was that it was introduced during the Obama administration and the conservative think tanks went to work immediately to put out propaganda trying to make it into yet another culture war prerogative. It’s been most recently tied to critical race theory even though CRT isn’t taught in anything but collage law classes.

    In fact, the one that pisses me off most is how they’ve demonized the new math curriculum simply because it doesn’t jive with how it was taught in the past. But the way it was taught before was thought up by 1800’s school marms and the new math standards were developed by actual mathematicians who knows how math works far better than a 19th century school teacher. Kids who are taught the new math standards will be capable of more advanced math far sooner than their parents and grandparents ever were.





  • a tankie like me

    I’m not sure you understand exactly what a tankie is. I mean, do you really think it’s all right to sacrifice (I.E. straight up murder) people to the ideals of communism and socialism?

    Being ultra liberal is fine IMO, even having the attitude that we might have to have use violence to overthrow of our government in order to get liberal ideals to be a part of our system is somewhat okay. But to think that our government, should it become communist, should be allowed to kill people in order to maintain a socialist or communist society is just straight up wrong and as far as I know that’s what a tankie is, someone who thinks that Tiananmen Square and Stalin’s reign of terror was just a necessary evil in order to strengthen the communist societal norm.
