but just to give you an idea of how far we are, we're a speck of a speck of a speck inside here, a pixel of a pixel in the center here, to make it from our solar system, or in particular from earth maybe to the nearest star, or maybe the nearest cluster of stars, the alpha centauri they're the nearest cluster of stars, there's 3 stars, alpha centauri a, which is the largest, alpha centauri b, and then there's one that you can't observe with the naked eye, alpha proximus, or i think proximus centauri i think it's called, not alpha proximus, proximus centauri, so that's a much smaller star, but that's the closest star, and this whole cluster of stars, and they're the closest, is about 4.2 lightyears away, or another way to think about it, if someone were to shine a light on one of these planets and assuming that light could get to us it would take 4.2 years to get to us, or if this guys were to dissapear or blew up we wouldn't know it for 4.2 years and you might say 'hey, that's not too bad, we should take a trip over there and check them out and see if there are any other people there that we can meet, and exchange technologies with or whatnot', but this is a huge distance, just this 4.2 lightyears is an unbelievably ridiculous distance, and just to give you a sense, the voyager i and il, we talked about them in the last video and we an even see how far they've gotten, they've gotten pretty much to the heliopause, this guys are traveling at 60,000km/h which is the same thing as 17km/s, if we were able to get up to those type of velocities, and this guys got up to this type of velocities by leveraging the gravitational pull of some of the larger planets to keep accelerating, so this is a pretty hard velocity to actually reach, but if you were able to reach that velocity and go straight to the direction of the alpha centauri system, the closest starts to earth, it would take you 80,000 years travelling at the same velocity as voyager i, which is the fastest of the voyagers, so it's a ridiculously long time, so we're gonna have to figure out some better way to do that.
