Got my hands on a Pfluenger president rod and reel at a garage sale! So excited! Would like to purchase a baddy assay at a good price. But either way I’m excited to get a great new crappie rig for at least $4.
Error being blown out of your mouth is similar to DC ( direct current ) and that it’s a continuous wave of air with frequency zero. While speaking is like AC ( alternating current), a longitudinal wave that moves back and forth at a variety of frequencies.
I have heard this mentioned several times with this exact wording, that faster than light travel would break/violate causality and I do not exactly understand why and how it would do that. Could someone more well-versed in physics explain to me why that would be the case? Or is it not the case? (Yes, I am fully aware, that...
This argument, as far as I know, relies on the nature of time dilation. You see as your velocity increases closer and closer to the speed of light, time itself begins to slow down. This is not an analogy or some fancy math trick, this is a real thing you can measure in the lab. As you get closer and closer to the speed of light time slows more and more. Such that as you reach the speed of light (again this is physically impossible at least for anything with mass) you can think of time as stopping. So for light or anything that moves at the speed of light they’re kind of isn’t such a thing as time, but I digress.
So (again even though it’s actually impossible), what happens as you start to go faster than light? Does this trend continue? If it does that would mean that time starts to reverse. And once you see that faster than light travel might imply time reversal, it should be easier to understand how this would violate causality. Because how do you get event A caused by event B when event B was before even A?
I've wanted to contribute to open source projects for years. Ive contributed to a few things in the past, but my expertise just isn't in programing (I'm a physicist), so it's hard to contribute meaningfully. Recently, I've heard about some open source silicon manufacturing and I'm intrigued, this is something I think I could...
What’s your dumbest app idea
I need too build one for school, I figure this would be a way to brainstorm
Found a great bargain for a new fishing rig (lemmy.world)

Blowing air out of your mouth, like blowing out a birthday candle, is just a DC form of talking.

Does faster than light travel violate causality? Why/Why not? How?
