@anorlunda Thanks! Never heard of flywheel, interesting concept. @Baluncore Thank you! ..*facepalm!.. Of course, when the piston is at the very end on one side, its in the middle on the other side of the train and the crank attachment is positioned either at the top or bottom from the...

Hi, First I'd like to apologize, for this question probably sounds devastatingly stupid to people on the forum. Why does the wheel powered by a typical locomotive steam engine rotate only in one direction? I don't even understand why doesn't it sometimes just rotate half-way around and then...

Again, my knowledge of quantum physics is so poor, I have no reference to give me any idea about the measure of stupidity of this question, so please bear with me.: Could it be that the nature of a ‘particle’ doesn’t change? That when decoherence occurs the wave function collapses into a new...

Thanks for the answer. I understand that kinetic energy is a component that increases observed mass but if I'm not wrong it shouldn't add mass to the black holes themselves, meaning the size of a black hole doesn't change with its kinetic energy. Maybe I got it completely wrong, i just wish to...

I’ve heard that the black holes that merged together and were the source that triggered gravity wave detector, have lost three solar masses. I understand to a very limited degree the basic notion of energy conversion like is the case in nuclear fusion/fission, annihilation, chemical energy...

Thanks Nugatory for the explanation! Now i have a clearer picture about the role of Planck constant.

Thanks PeroK for making that clear! I guess i'll stop watching documentaries on physics, they just seem to make me dumbero0).

By “this” I meant more generally, how the world works on a fundamental level.If I recall well, various popular sources like documentaries and some science podcasts mentioned that particles can occupy only certain energy states derived from the Planck constant. I was also puzzled by that since...

I thought as there is no fluent transition between energy states, there can't be fluent transitions in position when those changes occur and that the lP is the smallest distance a particle can move. I'm sorry, I'm very curious about this, but i don't really understand physics, certainly not most...

or does it have to do with the uncertainty principle, that at such small scales the object can't by pinpointed so the idea of how much it moves has no substance?

so is it possible for an object to travel less then one Planck length unit?

Well lP is the smallest distance it can travel, so if it moves 2tP/1lP which is c/2 (if I'm not wrong) then it has to stay at the same spot for two tP units because 1tP/0.5lP doesn't exist. So even when object is pulled by some force or gravity it somehow works only on every n-th time

So object that constantly moves half the speed of light literally stays every other Planck time at the same position, and object that moves third of c changes position on every third tP? thats weird

haha I'm sorry I'm a retard, i thought i read it and just assumed the definition is just something like that those are the smallest units of space-time. Well now i know. Thanks and sorry.

Hi, I'm no physicist and i have no clue how stupid this question is and i know how it would be possible to verify if its true, knowing 'c' in 'm/s' but the numbers are so huge (or small) i don't think i have a calculator that could do that. So is the speed of light one Planck length per one...
