What was the Big Bang's equal/opposite reaction?

[ac15]

What is it. Doesn't every reaction have an equal and opposite reaction? Does this mean that there is an antibig bang somewhere? Or could there be a backwards universe somewhere?

A backwards universe has little acceptance amoung main stream astronomers, so perhaps the big bang is an exception. Can someone explain the equal and opposite reaction to a small or mid size explosion? Neil

No. Maybe.<br /><br />LAW) For every addition, there's a subtraction.<br /><br />The LAW does not imply that there be an anti-bigbang "somewhere". An anti-big bang may exist as the only other existing universe, just so long as, together with our universe, the amount of energy does not change. If the amount of energy changes, then there's even more than this "anti-big bang".

Theoritically it is possible.But we can never perceive.

Hello. I'm only a Grade 8 student in Canada and I may not have an understanding of astronomy or physics, as good as some of the more "seasoned" members of this forum, but I hope you find my theory interesting.<br /><br />I know this an old topic but I was kind of interested, so here I go:<br /><br /><b>Every Action has an Equal and Opposite Reaction?</b><br />This is the third of Sir Issac Newton's laws of physics, and one that is very important to space flight. Here's how it works. If you push on anything, it pushes back on you. That's why if you lean against the wall, you don't just fall through it. The wall pushes back on you as hard as you push on it, and you and the wall stay in place. If you throw something, you put more force behind it than just leaning on it, so it pushes back with more force. This is hard to observe, because usually, if you throw something away from you, the friction between you and the floor makes resistance to keep you in place.<br /><br />But if you take away the friction and try again, you will move away from the thing you threw as much as it moves away from you.<br /><i>taken from: >http://www.qrg.northwestern.edu/</i><br /><br />I combined this with Einstein's theory that space and time curls in on itself, and I came to the conclusion that, if the Big Bang shot all the debris away from the center of space, eventually space will curl and all of the debris will return to the center point, colliding and causing a second Big Bang.<br /><br />Also since space moves faster and faster with every million years, by the time space folds in on itself it will have generated enough speed and energy, to provide the fuel for this second Big Bang.<br /><br />I also came to the conclusion that Einstein's theory of a finite universe is plausible. There may be no infinite universe, but a series of finite universes. Maybe our universe wasn't the first universe. Maybe it is a universe in the series of fini

<i>"...if the Big Bang shot all the debris <b>away from the center of space,</b> eventually space will curl and all of the debris will return to the center point, colliding and causing a second Big Bang."</i><br /><br />I just wish to make a quick comment concerning the highlighted part of your statement above:<br /><br />As I understand it; the universe started life as a singularity, with time and space expanding into the "Center" of the singularity. The singularity itself could not have expanded outward because there is no <i>"There"</i> for it to expand into. <br /><br />The universe (space and time) is being created solely within the confines of the singularity, since that is the only place it can go!<br /><br />In my opinion there is still no acceptable model describing how the universe may someday collapse in on itself. I think that once time and space were let out of the bag, there's no reining them back in...<br /><br />Note that the infinite universe is entirely contained within a very finite singularity!<br /><br />I hope this simplifies things for you; I would be happy to expand on these comments.<br /><br />

 

[student101]

I'm sorry, but I am having a little trouble understanding your comment.<br />Are you saying that the universe goes on forever, but is contained within a something that has bounds? <br />What I seem to get from your comment is that the universe is inside of this singularity, which has bounds, but the universe inside is constantly losing and gaining matter, therefore it can never be completely gone and can keep going in this cycle forever.<br /><br />Are you saying that the universe can go on forever in terms of distance, and the universe is also eternal in terms of time?

 

[neutron_star69]

i am confused as well, if our universe can expand forever, then how is it contained in something that has boundaries? maybe our universe isnt inside anything, maybe our universe is the only outcome of the BB and we are just trying to come up with ideas to fullfill fantasies that we wish were true

 

[neutron_star69]

Question: What's inside a singularity?

 

[student101]

I believe that our universe is inside the singularity and surrounding our universe is recycled matter that fills the singularity.

Quarks=Universes?<br /><br />http://hyperphysics.phy-astr.gsu.edu/hbase/particles/qbag.html<br /><br />Quarks:<br /><br /><font color="yellow">Bag Model of Quark Confinement<br />In dealing with the nature of quark confinement, one visualization is that of an elastic bag which allows the quarks to move freely around, as long as you don't try to pull them further apart. But if you try to pull a quark out, the bag stretches and resists. <br /> <br />The quarks of a proton are free to move within the proton volume If you try to pull one of the quarks out, the energy required is on the order of 1 GeV per fermi, like stretching an elastic bag. The energy required to produce a separation far exceeds the pair production energy of a quark-antiquark pair, so instead of pulling out an isolated quark, you produce mesons as the produced quark-antiquark pairs combine. <br /><br />The models of quark confinement help in understanding why we have not seen isolated quarks. If one of the constituent quarks of a particle is given enough energy, it can create a jet of mesons as the energy imparted to the quark is used to produce quark-antiquark pairs. <br /><br />Experiments show that the forces containing the quarks get weaker as the quarks get closer together, so that within the confines of a baryon or hadron, they are essentially free to move about. This condition is referred to as "asymptotic freedom".</font><br /><br />Universes????<br /><br /><font color="yellow">Bag Model of Universe Confinement<br />In dealing with the nature of universe confinement, one visualization is that of an elastic bag which allows the universes to move freely around, as long as you don't try to pull them further apart.

well i guess students theory could be true but how is matter recyled and what kind of matter is being recycled? another thing, if a singularity is inside a black hole then isnt your theory stating that we our universe is in a black hole? then if black holes exist and we could somehow reach a black hole, then we could be transported to another universe. But if black holes are only myths, then your theory cannot be possible.

 

[kmarinas86]

I prefer the Earthling's perspective of the black hole versus the "black hole's perspective of itself".<br /><br /><font color="yellow">But if black holes are only myths, then your theory cannot be possible.</font><br /><br />Singularity is a myth! Massive dark objects certainly do exist.<br /><br /><font color="yellow">if a singularity is inside a black hole then isnt your theory stating that we our universe is in a black hole?</font><br /><br />No.<br /><br /><font color="yellow">well i guess students theory could be true but how is matter recyled and what kind of matter is being recycled?</font><br /><br />The same way quarks are recycled inside the atom.

<b>Student & Neutron -</b><br /><br />Exactly! Before the BB there was no time or space; we can't understand how or why, but there occurred a singularity - an infinitely tiny point. <br /><br />From within this this infinitesimally tiny point, time and space are being created. The creation of time and space has been going on now for around 15 billion years (by some estimates) and there is no end in sight.<br /><br />In a singularity, every point is the center and edge of the singularity - because it's an infinitely small point! Note that this is precisely how every point in the universe views itself today. <br /><br />We perceive ourselves to be at the "Center" (or the oldest point in time and space) of the universe and also as the most rapidly expanding point. Every other point in the universe also shares this very same perspective.<br /><br />Therefore; it is logical to conclude that our infinite and never ending universe is being created while wholly contained within the finite confines of a singularity.<br /> <br />The universe is bigger than the box it comes in....<br /><br /><big><b>E=mc²</b></big><br />

Does the infinitely tiny point keep getting smaller? How can a point have kinetic/dynamic qualities?

[neutron_star69]

you guys still have theories of singularities and all but you cant be sure of the fact that are ture black holes that exist and it is propsed that only black holes have singularities so how can you conclude that our universe came from one or is still in one?
