Several days ago I started thinking about the mystery of dark matter (yup, it was after LIGO discovery, and we all do it from time to time, right?). Then I came up with a strange conclusion that within our galaxy, there should be an equivalent of about 24 000 stars that we just cannot see--in...

This example is obviously correct but it is far too complicated to be useful in any way, just like all examples involving living creatures. The simplest example of time-asymmetry and the simplest example of entropy I could think of is this: Two adjacent balls, simultaneously hitting a third...

You guys made a good point, I can see that entropy is not time-symmetric. And I don't want to dismiss it, but... Well, entropy is more like an effect, an observed result, not a cause of why do things happen. So it seems to me. And if it is not just an effect -- is it a reason for all asymmetry...

My question is slightly philosophical, so be warned. If we could only experience the world through a recording played backward, what laws would we form? I am asking, because the strangest thing occurred to me: at least some of these laws would be exactly like ours. Say, you have two coins...

Okay, let's go with the flow. What are the 'points' of the 4-dimensional universe around us? Are they the independant, fundamental elements? Like, maybe, photons, electrons, quarks? Or is the 4-dimensional universe made up of collisions, interactions, relations between these elements? Which...

I know this has been mulled over time and time again in different threads, so I will keep it short. Which statement is more consistant with reality: 1. A dimension = all existing and non-existing points along an axis. 2. A dimension = all existing, but only existing points along an axis...

I have decided not to publish my further arguments in this topic. Anyway, I can see that it does not precisely follow the forum rules. Nonetheless, thank you, Peter, for any and all input you have given. I will come back to this topic to see if you (or someone) had anything else interesting to...

About forum rules. It is not my intention to break them in any way. I understand that if my ideas were at any point inconsistent with, for example, theories of relativity, then they are wrong. In case I still break the rules somehow, just tell me, and I will stop posting. Why do I get an...

I had some interesting ideas concerning the mechanics behind the space expansion and its acceleration. Here they are. I know you expect blunders, but I hope you will find something interesting. Starting with obvious:1. In the presence of strong gravitational field, time flows slower than in its...

Right. Thank you guys, and as far as I am concerned, this topic can be closed.

I admit I did not read about Doppler Shift in the FAQ you mention--I it was my impression that the Shift (on its own) cannot be responsible for lack of symmetry in the twin situation. As AT said, it is crucial that I want to discuss only what the twins see optically, not what happens in their...

Well, I am definitely not a person to defend the guy in the video. But he can't be totally wrong. There must exist at least some period of time, from "traveller's" point of view, when the other twin ages faster than him. This: http://www.phys.vt.edu/~jhs/faq/twins.html doesn't address it at all...

@Nugatory: http://math.ucr.edu/home/baez/physics/Relativity/SR/TwinParadox/twin_paradox.htm doesn't work :(

I was drinking coffee and just clicked something on youtube. This, I think: Minute 2:40 Well, my bad, I know that most of youtube is crap, really :oops: The guy published some book though, so he looked sort of legitimate...

If there is maximum speed in the universe and we call it c, and it is not relative, is there also some ultimate rest state, an unrelativistic "0" speed? I sort-of know that there is none, because it would mean that there exists a non-relativistic frame of reference. But I can't quite grasp what...
