You cannot. The speed of light limits you, even as you approach it, by changing distance itself.
There is no absolute distance between two points; all astronomical distances are calculated in a non-relativistic framework. This is perfectly acceptable, since we all live in that framework relative to each other, and even if we were talking to multi-generational "friends" on Alpha Centauri, it would still hold true for both sides (to within an imperceptible error).
This is why it is sometimes suggested that photons don't "travel" at all; because they move at c, every spot they go to is the same spot to them. A divide-by-zero non-error.
- somenameforme 5d agoYou cannot what? Everything I said is completely accurate. As is your conclusion - with the speed of particles being infinite, from their perspective. This is also why it's 100% possible for a human to travel to Alpha Centauri, or even the edge of the known universe all within a single human lifetime, from his own perspective. Of course for an at rest observer, billions of years would have passed, but for him - mere decades.
