Die Lichtgeschwindigkeit ist eine Lüge - und Physiker wissen jetzt warum

We have absolutely no idea how fast light really is. Einstein himself only ever expressed speed in two directions, never in one. What exactly does that mean? Well, you'll find out here! With the codes Entropy15 and Entropy10, you get a great discount on Naturtreu products! :) https://serv.linkster.co/r/46AXVT1X7G I've been working with Naturtreu for a long time because I'm absolutely convinced of their quality. Whether you want to support your immune system with "Protective Shield" (vitamins C, D & zinc), strengthen your nerves with "Nerve Strong" (B vitamins) for stressful periods, or treat yourself to a vitamin D boost with "Sun Friend"—here you get pure nature without unnecessary additives. Be sure to check them out! Nothing is faster than light. And we know the speed of light very precisely. 299,792,458 meters per second. That's pretty precise, isn't it? That's the foundation of modern physics. And that's how Einstein formulated it, too… right? If you look at his work more closely, something stands out that seems completely insignificant at first. He never actually talks about how fast light travels from one point to another. But always only about how fast it travels there and back. That sounds like a small detail, and yet this little remark turns the entire universe upside down. Because the moment you try to measure light in only one direction… from A to B, you run into a problem that you can no longer solve. Because suddenly a question arises that you actually thought had long been settled: Do we even know how fast light really is? Or are we measuring something completely different all the time… without realizing it? Welcome to what is probably the most fascinating question in physics.
