I was watching a sausage making video, and youtube recommended this, and wow. Such a happy, positive, great!. I was intrigued

The simplest way I can explain it is that everything is always moving at the exact same speed, divided up between the three spacial dimensions and the time dimension. Light does not move through the time dimension at all, and therefore is always moving at full speed through the three spacial dimensions: ie. speed of light.
......nooooooo?
I mean. You aren't wrong. Einstein went to his grave haunted by the notion that his explanation was missing something important, and nobody yet has been able to figure out what.
Photons don't interact with any of the three dimensions as we know them at all, especially time. They exist in all places AT the same time, theoretically, and they don't seem to dissipate based on the passage of time, but we literally have no way of proving that one way or another. They just seem to be around.
Okay, I'll admit I was expecting you to have a better reasoning for what you said than "we don't know anything."
Also, the three spacial dimensions are the x, y and z axis. Time is the fourth dimension of Einstein's spacetime, which he did openly admit wasn't quite the right way of looking at it anyways, but rather it was just the best answer he could come up with.
