A constant speed of light in all reference frames? Surely you can't be serious.

I just saw this post for the first time, quoted in someone else's response. I actually disagree here, since the rest length of the rod is the magnitude of a 4-vector. What that tells us is that we can construct the rest length out of frame dependent measurements. It's true that it's only measured as length in one frame but it can be built up out of measurements that we take in another frame, which is equivalent to accounting for the differences in simultaneity between the two frames when we make our measurements. It's certainly an invariant property, and it's specific to the rod, so I don't see why it shouldn't be called intrinsic.

Physicists don't talk to other physicists about the book flatland (unless it's for fun?) but it's something that we think maybe non- physicists can relate to and which they might already have a visualization for. If he were talking to another physicist, he'd tell him to visualize a spacetime cross-section with one axis representing t and the other two representing x and y, or something like that, and the other physicist would recognize what that physically represents. Since we're dealing with someone hear who clearly *doesn't* understand what that physically represents, it's useful to try to get him to picture something in which he might have already visualized a 3 dimensional object interacting with a 2 dimensional world. The 3 dimensional object interacting with a 2 dimensional world, to another physicist, would be understood as a cross-section of a 4 dimensional object interacting with a 3 dimensional world. But since you clearly don't understand what that means, to simplify, we write in terms of a popular novel.

You said, "This is due to how the wave function collapses as it passes through the slits". Is the 'wave-function' physically passing through one slit or multiple slits or is the wave-function not physical and what occurs in a double slit experiment is magic? You do understand there is a physical C-60 molecule, a particle of matter, traveling towards the slits, correct? And you understand there is a physical C-60 molecule detected, correct? I am asking you what is physically occurring during the time the C-60 molecule is interacting with the slits. Now, if you want to use 'wave-function' drivel go right ahead. But is the 'wave-function' physically propagating through one slit or multiple slits? Of course, you can't answer this because 'wave-function' has nothing to do with what is occurring physically in nature. It is a mathematical construct made up by those who do not understand what is physically occurring in nature. At least the other poster had the guts to say the 'wave-function' physically enters one slit if there will be detectors at the exits to the slits when 'it' gets there in the future and the 'wave-function' enters the available slits if there are not detectors at the exits to the slits when 'it' gets there in the future. You won't even do this and hide behind 'wave-function collapse' like it is some type of magic wand.

It's magic, and it turns out that it's actually fluffy white bunnies that create the interference pattern out of the carrots that they harvest out of the enchanted forest. I told you, I already know that you don't have the capacity to understand any rational arguments I make that relate to actual quantum mechanics. So, if you'd like to discuss the fluffy white bunnies some more, I'll be glad to comply. But I am not going to try to discuss physics with you. It would be a gigantic waste of my time.

You are not discussing physics. You are discussing magic. You have no idea what is occurring in a double slit experiment so you just label the physical behaviors 'wave-function collapse' and stick your head in the sand. If you agree the future determines the past and the C-60 molecule enters one or multiple slits depending upon their being, or not being, detectors at the exits to the slits in the future why don't you just say so? Because you don't believe the future determines the past and understand it to be absurd nonsense, that's why. |
