Thanks for taking your time making that great post! So much information, I'll have to read it a couple of times to let it sink in :)
What you said in the end is something I haven't thought of at all, but it's so true..
Ok then I'll try to be more precise next time.
Sorry for off topic but I have a question I hope you can answer. If I have a clip about something claiming to be scientific could I make a thread in this part of the forum and ask if there's any truth to it? I'm watching something at the moment...
So basically what you are saying is that I shouldn’t ask questions because I can find the answers in books...Tell me what the point of this forum is then?
If I've read something I don’t understand and if I shouldn’t turn to a forum, what should I do Mr. Science Advisor?
I think I pointed out...
Thanks for the link but there is no way that I can understand that. Enormous amount of text and I don’t get any of it. Is it really impossible to explain stuff for the layman in a short, simple, concrete way? I guess it's not possible since I haven’t found it anywhere and the subject is so...
Hi
Did Feynman's discoveries have a big impact on technology? If it did, in what way? I'm trying to learn about what he has accomplished but it’s not so easy with my limited knowledge of physics. I just know he won a Nobel Prize and was considered the greatest physicist of his time.I want to...
Sorry but I don’t understand what you mean with rest frame. To make it simple for me. I know the amount of energy it takes now to accelerate a ship to 1/10 of light-speed, but if I want that ship to continue traveling at 1/10 of light-speed for a long time I don’t need any further energy? The...
But wait that's what I meant, after the velocity is reached I want the spaceship to travel at matching velocity to the target destination e.g. 1/10 of light-speed. Does that not require any energy at all if you avoid collisions? Or did I misunderstand what you meant with matching velocity?
Oh my bad! I got it wrong because here in Sweden our decimal comma is your decimal mark hehe. Your calculation is the same as the one in the article but a lot more detailed :)EDIT: Missed your last sentence. That’s great and fitting to know since my original post was about that speed. Great...
By the way I read on Wikipedia a moment ago about Interstellar travel, and something boggled my mind. I'm not sure I understood it correctly but they said that it would take roughly the same amount of energy to accelerate an object of 1 ton to 1/10 of light-speed as the whole world's energy...
Sorry if I was unclear before its hard to formulate the question right when I know next to nothing aboyt physics and relativity. I meant a journey to a star that's 50 light-years away from earth.
Wow that was exactly the kind of answer I was after. Really amazing information...This question is...
Hi!
If you started a 50 light-year journey at the age of 20, traveling at 99.9% of the speed of light, would you look like 70+ years old when you arrived at the destiantion? How much would you have aged? And how would you experience the time on the spaceship? Would it feel like 50 slow years...
