I promise to view any diagrams you post in exhausting detail, pervect. :) My purpose here is not to argue, it's to figure out what I'm doing wrong.

Lets look at that in more detail. I always see my clock tick at a rate of one second per second. I cannot see otherwise. If we specify that "measurements are done with the reference system from which I depart," then the longer I spend in my 1 m/s/s Constant Acceleration Spaceship, the...

Most of the evidence I've seen is of "extremely massive spots in space." Then these "extremely massive spots in space" are presumed to be black holes. How do you tell from a billion LY away whether that wad of mass is slightly larger than a basketball or is a singularity? Seems to me that...

The event horizon is something that only we the third party observers see. I would contend that the speed of light (as seen by a third party) is invisible and undetectable to a constantly accelerating observer too. But that the constantly accelerating observer's clock slows (in relation to the...

Finite time for the stuff falling into the black hole, but infinite time for the third party observer, it seems to me. But that's not how it's expressed in any of the books, and the guys who write physics books are smarter than I am, so I'm trying to figure out where my error is. Sure it...

I'm fine with saying that too. However it gets said, I as the dude approaching C in other people's inertial rest frames get my passage of time in their frame monkeyed with so I never crack C in their frame. How you phrase it is unimportant. What's important, in the case of near C velocities...

Well you can't tell, because there's no way to compare clocks until the spaceship lands, which means it's velocity can't be constant. Is that at the heart of where your going with this? It wouldn't. But it would require that it move through a point in space where time dilation relative to an...

I see that, but don't understand why can't we use the same argument to discuss exceeding the speed of light. Is time dilation a barrier, or isn't it? In the case of an observer falling into a black hole, his time appears to proceed normally to him, but the "universe's time" appears to speed...

Absolutely, and I can tell you're trying to set me up for the answer, but I'm still not seeing it, because when the spaceship comes back to earth, more time has elapsed for the Earth than the spaceship. When you bring the clocks back together and compare them, you discover which one was pushing...

Please explain to me what I'm missing: You can't go faster than the speed of light, because of time dilation. The faster you go, the slower time moves for you as compared to objects at rest, and time would stop for you if you ever went the speed of light. That's what makes C the universal...
