k and c can be set to 1 in a more real sense than the other constants because they do not have any fundamental units like length/time, mass/energy, or charge. By relativity, c's length over time cancels, but you should always conserve the sqrt(-1) that goes with time so its unit is 1/i. In other words, whenever you see "seconds" in units, like G and h, ...


I recently read that math/physics for a holographic black hole could be applied to the entire universe, I'm afraid the holographic principle is a mathematical conjecture that's more than twenty years old, and for which there is no evidence whatsoever. In fact, since all the evidence and experience says we live in a 3+1 dimensional universe, I'd go so ...
