Marcus Wolfe Posted April 1, 2008 Author Share Posted April 1, 2008 Perhaps when we start colonizing other planets, each planet (and all it's habitable moons) will have it's own calender. Then, there would be a calender for the entire solar system, and eventually the entire galaxy and/or universe. Link to comment Share on other sites More sharing options...

You can't just "make a calendar." That calendar has to be based on something. A calendar for the solar system could be possible, provided it's based off of a constant viewable from every colonisable planet and moon. But, I don't really know what that might be. A galactic or universal calender is nigh impossible, though...not to mention we'll never be able to colonise outside of the galaxy. Life just doesn't last that long. The closet galaxy to us, Andromeda, is about 2.5 million light-years away. So, even if we went the speed of light, it would still take 2.5 million years to get there.

Xeniorn Posted April 1, 2008 Share Posted April 1, 2008 Not, really, if you traveled the speed of light, it would take you 0 seconds, although on earth many millions of years would pass (2.5, to be exact). That's what Einstein's most famous theory tells us. :) The problem is speed of light is impossible for objects with mass>0.It would be in a way possible to travel 99.99999% speed of light, if you managed to accumulate such a tremendous amount of energy and use it in the right way, and then you'd get there in a few seconds, minutes or days or so. Without using some kind of wormholeish means of transport it is theoretically impossible to colonize the planet and then communicate with mother Earth. You'd need some corridor through space without passing through time. I'm not sure if current theory predicts the possible existence of such species. @ninja(earlier): Element has a half-life if it is a radioactive ion? Not really. You probably meant radioactive isotope. Half-life is defined for many things, in this case radioactive isotopes of elements. In theory all elements have radioactive isotopes, but we count only those we can find in nature or that have been fabricated in the lab. Hydrogen has one radioactive isotope, with 2 neutrons and 1 proton in its nucleus and is called Tritium, it's used in H-bombs IIRC, as a intermediate between lithium deuteride and free neutrons (don't kill me if I made an error, I'm no expert) You cannot measure time accurately because it goes slower for things that move faster. You can measure time accurately if don't have speed relative to the measuring device, if the clock is moving 1m/s towards the tree, you must move as well. If it's standing on the table, you have to stay where you are. Both you and the clock are moving as Earth revolves around the Sun but your relative speed is zero. @evilkoal (earlier): Electrons don't rotate around carbon atoms' nuclei, sorry :P It's an outdated theory, postulated by Ernest Rutherford and Niels Bohr, but changed to much more appropriate models in time. You learn that in school because that interpretation is enough for non-college students (maybe they teach it in some highschools as well) Sorry for being a smartass, I hope my knowledge can help someone understand. :) @Abramul: Sorry I didn't notice your post before, I now see I've said some things you already said before.

Marcus Wolfe Posted April 6, 2008 Author Share Posted April 6, 2008 Yes, that is how they teach it in high school. So Electrons don't rotate nuclei? Damn, that makes everything so confusing... Link to comment Share on other sites More sharing options...
