    “The only thing known to go faster than ordinary light is monarchy, according to the philosopher Ly Tin Wheedle. He reasoned like this: you can't have more than one king, and tradition demands that there is no gap between kings, so when a king dies the succession must therefore pass to the heir instantaneously. Presumably, he said, there must be some elementary particles -- kingons, or possibly queons -- that do this job, but of course succession sometimes fails if, in mid-flight, they strike an anti-particle, or republicon. His ambitious plans to use his discovery to send messages, involving the careful torturing of a small king in order to modulate the signal, were never fully expanded because, at that point, the bar closed.”

    ― Terry Pratchett, Mort

    I think there is mistake in shadow on the Moon example. Shadow can move only with speed of light because shadow is dependent on llight that goes from Earth.

    The Greek translation has a flaw:
    Currently is,
    “Ποιά είναι η ταχύτητα του σκοταδιού”
    and it sounds bad(because uses the popular version of the word “darkness”)
    The official word should be “σκότους”
    And all together:
    “Ποιά είναι η ταχύτητα του σκότους;”

    Sixteen percent of the dark energy in the universe emanates from my ex-wife. She is old and will soon die. When this occurs, could the consequent shock wave end up shredding the fabric of the universe? No one of any influence seems to recognize this threat and I am unaware of any measures being taken to address this concern. Could she be placed in a medically induced coma to dissipate this energy in a more gradual manner that will prove less cataclysmic for humanity?
    Dr. Davis of the College of Charleston has been alerted to the danger but he seems rather cavalier the about whole thing. Likewise with Dr. Tyson in New York. Can you direct me to the proper agency or individual? Time is growing short. We are becoming anxious here in Moncks Corner, SC.

    How long would it take the shadow to appear on the moon? When a star dies it takes years for it to stop glowing from our point of view so how long would it take the light and then the shadow to appear on the moon?

    The speed of light is NOT the fastest thing possible in our "known" universe and is actually Extremely slow. If you still believe that...you just need to think.
    (Your thoughts just now traveled faster than light.)
    You may say, "Bull shit! Your thoughts can't be seen, heard or felt!" Really? Think about that.
    Your thoughts....can take you anywhere. Your thoughts.... can create anything.
    Just try to "think" what God's
    mind must be capable of.

    mind blown. something I been noodling for decades: Why a number line? Einstein proved space is curved... so why? I tried a number circle... got some math degreed peeps mad at me. It facilitates division by zero and infinity... and it gets rid of negative numbers which match physics (absolute zero and all)… but what about a number mobius strip which would cause all reality points to connect to each other...

    Night is not earths shadow falling on you. It’s just the absence of light in that region. It’s not like you’re on another planet and earth is blocking the sun rays from reaching you, thus casting a shadow but you can be on the object itself and still be shadowed by it.

    The speed of a shadow is just as fast as the speed of light, it needs to wait for the light from before to travel and disappear. Correct me if I’m wrong.

    I would love to hear your thoughts on this subject (the ignorance portion) when compared to black holes and the edge of the universe with the expansion of it in mind. Since data can not be lost, is the expansion of the universe, when applying the assumption that the edge of the universe contains all of the data of the universe within, merely showing the growth of knowledge and learning of what's within the universe? And if so, what does that quantify a black hole to be with the absorption of said data? Please comment or message me directly if you need a longer, clearer, explanation of what I mean.
    Also, loved this video, defintley one of my favorites of yours! Keep doing your thing!

    I was unaware that the given quote was by Einstein. I've heard a slightly different version, which I actually like better: "The farther I extend the radius of my knowledge, the more my circumference borders on ignorance." The effect you mentioned (Dunning-Kruger?) is REAL!!! Boy, oh boy, is it real. Ignorant people often hold the most untenable opinions, and they often hold them most tenaciously. However, as Frank Herbert pointed out, experts can run into their own problems; namely that of not believing there's much they DON'T know about their field(s). It often takes some young scientist to come along and say, "You old guys have it all wrong!" It's quite shocking when that turns out to be true! Such was the case a hundred years ago, when many scientists were sure there wasn't anything left to learn about physics. Oops. And that meteorologist who dared to tell all the geologists that the Earth's surface moves around? He was roundly lampooned, and died without seeing his finding vindicated. Not to mention poor Boltzmann. "Being an expert locks you up tight," one of Herbert's characters said, and boy, oh boy was she right. Rikki Tikki.
