    Trump Consciousness

    Copied this post from another thread because a reaction to it is more fitting here. Statements like this really make me believe in the existence of alternate realities, you must be in a completely different one than me David. In the one i live, Trump does not "say the odd untruthful thing...

    Yes! or even worse, republicans will claim you can not impeach a president at times of war, or instate martial law and simply cancel elections. Maybe sounds crazy now, but at the rate they are normalizing crazy, it is a matter of time.

    Doubts about the moon landings

    We all agree it slows down, although it would be more correct to say that the amplitude decreases. But the question is, how much? Facts here are, we see the bag for less than a minute, 16 oscillations or so, the video is not very clear. We know the amplitude decreases at least 25 times slower...

    Doubts about the moon landings

    OK, for but what it is worth, this how i got to that 25 times longer estimate: Everything else being equal, the bag swings 2.5 times longer just by changing the gravity, i think we agree on that. Then we have to take into account the factors that suck up the energy, most import being...

    Doubts about the moon landings

    That is mighty big of you LS, no sarcasm here, i am honestly glad you did not leave the forum this time. We were indeed discussing a purely theoretical situation, but nobody pretended it was anything else. It was meant to be some sort of baseline, to try to estimate the influence of the real...

    Or any thoughts on LS's thoughts on pendulum physics.

    Doubts about the moon landings

    The reason astronauts walk (jump) so slow, is te same as why a pendulum swings slower on the moon, it's gravity. If they take one of these unique jumpsteps, they accelerate an decelerate slower in 1/6 G , so they have more "airtime". Therefore they seem to move slower for locomotion. The rest of...

    Doubts about the moon landings

    This is from the link you provided (bolding is mine): How can this be more clear, where would you say that gravity extracts energy from this system? Gravity tries to restore the pendulum to it's resting position, in that sense it is the restoring force. But in doing so it builds up just as...

    Doubts about the moon landings

    My first statement in my previous post was Your reaction: So already from the first point we seem to disagree, i do not know what you mean when you say that gravity is the restoring force. The only source that seems to use that kind of terminology is this link you provided, and even that link...

    Doubts about the moon landings

    I know, the earth is flat, the moon is made of cheese, but i have to earn my lunars somehow, big moon does not pay me for nothing.

    Doubts about the moon landings

    Yes indeed, but it did not help me a bit to understand what you mean. Why don't you go through these points and state where you disagree, we can start from there. For future reference, i do not recognize "Sorry you are wrong" as a physics explanation.

    Doubts about the moon landings

    Then please answer when you have the time, because this post does not help anyone to understand what you mean. There is no need to rush. The physics here are quit clear. If you have good physics based objections, simply state them, maybe there are things we havent considered. This post did not...

    Doubts about the moon landings

    Agreed, if i understand correctly, the only difference is that the physical pendulum equation gets more complicated because part of it averages out the weights, to get to the correct pendulum length.

    Doubts about the moon landings

    They probably are for all practical purpose. I have almost no physics education at all, i provide guesses. You provided educated guesses in this thread, so your physics knowledge would already be at least one level higher. This guy explained the difference to me: Ideal pendulum: Physical...

    Doubts about the moon landings

    The inventor of the pendulum clock would disagree with you. What question? The ones you did not answer at all?

    Doubts about the moon landings

    No, that is not what i said, i said an ideal pendulum would go for ever. An ideal pendulum is impossible, as i said before. It would mean a friction-less pivot point a mass-less string, operate in a vacuum, and all mass at the lowest point of the pendulum. In these conditions it would go on...

    Doubts about the moon landings

    OK, but the question is, should we see a slow down at such a short time? Again what do you think slows the pendulum down in a vacuum at 1/6 G? As you demonstrate here.
