Ive been thinking about the movement of things recently. How we measure things here on earth but for some reason we don't add up all the variables... its kinda weird. So here is a general question that has been giving me a big ache. So, for instance, If particles can be accelerated to 0.99999999 the speed of light, and the earth traveling around the sun at 108,000 km/h and the solar system moves at around 675,000 km/h and our galaxy moves throughout space at around 900,000 km/h, than what is really going on here... maybe im missing something but would that mean we have already blown past the speed of light? I'm sure I can be proven wrong very easily haha. This is not homework or anything like that, just something that has been on my mind and i would love to hear what professionals and academics have to say about my silly observation!
