Can you please estimate me the point of where earth is positioned in the expanding universe relative to the centre.
If we see the universe expanding in all direction the same pace will put aerth into the centre of the universe again.
If we look into the past we see things going away very fast.
go towards mars and hang a right…

According to latest theory. The current round of expainsion is not caused by the big bang itself, but by vaccume engery or the cosmological constant. Basicly its considered a property of empty space that it pushes out.
Thus, we expect things to be expanding uniformly just about everwhere. So there is no indication of where the center of the universe is.
Furthuremore, there is a limit to how far we could ever see- assumeing faster than light travel is bubcus. Thus we will never know the overall shape of the universe or where we are in it. Until we figure out another way.
how does nothing push?

I love vacum. Vacum is really a gas with zero pressure. If we put a balloon of air into space it will expand then blow up and the air will spread out to all directions forever. But first the edge will expend and this expansion will gradually travel towards the centre. Can we see this spread of expension?
We are looking at faraway stars and galaxies and see them moving away from us. Maybe they are not moving in space only in time.
If the speed of light is an ultimate barrier of the universe, can not be surpassed, than looking back in time might mean moving away with the speed of light.
I presume that it was a joke…
Oh man… Hume does not work, ok? Get the vaccume philosophies outta here…
LOL this was a physics question, not an epistemological one…
space does nothing, as it is nothing… the distance between objects changes as they move further apart may have some merit, but that is on the measurement between objects, not between object A and nothing…
-Imp
Well, I wouldn’t call void nothing, precicely because it does push. Of course this is all very new theory and could be proven wrong. It’s also called dark energy, if you want to look it up.
is it void pushing… again, how does nothing push- or is it gravity from ginormous celestial bodies? I think it is the latter…
-Imp
LOL…
Again, the meta-physical mind is proven to be minor in the realm of the physical. You see imp, in science, we don’t imagine things to their wildest groundless terms possible, we analyse the evidence and make strict logical conclusions from it, backed up by experiementations. I’ve no doubt that you can manage the logical part of the job, but before that - you’ve got have the baisc facts sorted - physical facts I mean, not meta-physical as when you do Hume - they do not, I repeat, do not count…
btw, it was a serious question, how does nothing, void, space or whatever name for nothingness do anything?

Here we go again indeed… On the matter whether the Sun shall rise tomorning or not: I let Probability take over - screw Enistein on this, I’m all for Bohr. But where is the British Empiralist in this - where is Plato in partical physics; where is Aristotal in biochemistry; where is Darwin even, in genetics? So do not tell me that I’m being simply stupid to judge that the Sun will rise again…
btw, I knew you meant to ask a question, and that’s why I gave you a subtle reply, just to make you realise that there is a certain crap on top pf your head that you must nod off in order to understand what you are talking about in the first place. If you brought up your original question in a lecture hall of physics, the lecture would shake his head mad and walk off stage in dispare over his failure on educating…
As I said: you must get some basics sorted, at least, before you attempt to even think about such a question. As a recommendation for this case, you should start with the basics of partical physics which deal with fundamental particals ect. There is a special family of particals named Gauge Bosson, that can be directly related to your question. Frankly, I don’t consider myself informed enough in that matter to give you a thourough explaination here.
particals are not “empty space” they are something rather than nothing…
-Imp
Logical or not - doesn’t matter - it works and that’s what matters.
Let me give you a clue with my two year A-level physics: when going down the tree of fundamental particals, you eventually step on tot he boundary of mass and energy, with the problem of force. The speciality of the bossons is that some of them are responsible for giving mass, and serve as force themselves. I knock you on the head, and your head pop open, it happens when bossons from my hand are transmitted onto your head - this transmision is the act of force. For this reason, the bossons are also called exchange particals.
The existance of the Ether is not proven, nor defied - hence also the nature of vacume. Surely you’ve heard of the phrase that nothing itself is a thing, with a “n” and a “o” at front? Mass is the concetrated form of energy, and what is energy? Photons, travelling all over the space in rays and waves. When you take all these into consideration and more, you face a problem which is as nasty as the nastiest meta-physics ones. We sit and waite for the frontiers in the quantum field to research and develop matters further. But one thing I assure you - they won’t be referencing from no Hume…
that doesn’t resolve the problem…
particles are something…
nothing is nothing…
-Imp
I didn’t say that I was here to give you an anwser, for your question itself is somewhat twisted out…
Maintain thy meta-emperialist ego - I’ve got no problem. All I’m saying is that a philosopher is a brain without cells, when lacking knowledges from all other fields. And that some of them should put the books down and get out more just to draw in some fresh O2…
imp, rock on man, your fab look is still there… in the other forums…
Vacum is, as we know is not a gas but it defenetly acts like it has zero pressure.
Imp, I think Space just might be innapropriatly named. What we commonly refer to as space and vacuum isn’t literally nothing but the space between objects. Apparently where we thought there was nothing, and initially called space, there is indeed… stuff.
space is space, void is void, ether is ether…
changing the name avoids confusion…
