death of universe by a new begning
ther are many theories about the end of the universe.......
like big CRUNCH,big freeze....
Big Crunch is one possible scenario for the ultimate fate of the universe, in which the metric expansion of space eventually reverses and the universe recollapses, ultimately ending as a black hole singularity.
BIg freeze:-expansion of the universe will continue forever.and ultimatly elements molecules disintegrate...space and time cannot hold such large entropy of universe and then universe will break into fragments and threads of time and space...Everdoby knows this...
both of these depend upon 2 factors----DRAK MATTER and DARK ENERGY.DARK MATTER tries to contract the universe(gravetation is helping it) and DARK ENERGY tries to expand the universe..
RECENT STUDIES shows that universe will be expanding for ever ….i.e., dark energy is powerfull then dark matter---->big freeze <
I am not agreed with both of thes….because
1>IF DARK MATER IS POWERFULL then DARK energy then universe will not be expanding
2>.And IF DARK ENERGY is powerfull then DARK MATTER then particles,dust (under only the effect on gravitation )will take about 2-3 more billion year s to form planet like earth,marse jupiter,….sun stars,…
this means that after big bang Dark matter is more powerfull ……
but something is making Drak energy powerfull enough to make universe expand and to create enough space for trillions of stars
Now came to >> BIGBANG<<
big bang>>explosion at a point>>formation of sub atomic particles>>formation of planets ,stars,universe
and I think that `this` additional power of dark energy is EXPLOSIVE ENERGY due to enormous explosion durin big bang.Consider a ballone filed with air brust…produces shock waves…which expand air..and create brusting sound.
Samething would have happened during BIGBANG.Enormous explosion has thrown the dark matter ,molecules away from each other,speading dark matter in whole universe…leding to expansion of universe which is continue till now at accelerating speed.
But a time will come when EXPLOSIVE ENERGY will be used up in increasing entropy of universe and will slow down..and came to halt.At that time DarkMatter will dominate and Universe will be start srinking at slow but acclerating speed and evantually shrinks to a small point (like in bigbang) at very high speed.
At this stage energy of that` point` will be very high…..anti matter half of the universe start anhillating matter half of universe and energy of that point will became so high that an explosion will take place (like big bang)and again the formation of the universe will statr.
THUS ALTERNATE EXPANSION AND CONTRACTION OF THE UNIVERSE WILL CONTINUE FOREVER … FOREVER … FOREVER … FOREVER … FOREVER … FOREVER … FOREVER … FOREVER … FOREVER …
This theory also explain the cause of sepration between matter and anti-matter at the time of formatio of universe.,AND follows ENERGY-MASS conservation.We see that nature like symmetry and cyclic order thus
THUS ALTERNATE EXPANSION AND CONTRACTION OF THE UNIVERSE WILL CONTINUE FOREVER … FOREVER … FOREVER … FOREVER … FOREVER … FOREVER … FOREVER … FOREVER … FOREVER …again
Plz comment on it…
I have more of this type of new theories about universe,earth,life formation…….

Also, since your ideas go beyond the standard consensus by predicting an outcome contrary to the standard model of cosmology, any discussion might result in your thread being moved to Pseudoscience. But I will respond so you can consider some short comings to your view.
The ideas of "shape" of the universe are consistent with the possibilities in General Relativity, i.e. the Big Rip or the final Big Crunch, depending on the energy density of the universe.
But you have gone beyond that to discuss a separation of matter and anti-matter at the instant of the Big Bang and then have entertained the idea of dark matter eventually pulling the expanded universe back together allowing the annihilation which I think you equate to a new expanding universe. You see that new universe following the same pattern and that leads to your prediction that there will be an endless cyclical Bang/Crunch/Bang, alternating between a excess of matter and an excess of anti-matter. Is that what you were saying?
If so, here are a couple of considerations. Why would anti-matter get separated at the Big Bang instead of the idea that annihilation occurred but there was some matter left over that became our expanding universe. But that doesn't matter all that much since any answer is very speculative.
But a bigger problem is space. The standard model depicts space as being created by the Big Bang and then as inflation occurred and on going expansion begins to accelerate, there is no reason why the dark energy will run out, but within the created and increasing space, there is really no place for the anti-matter to hide since we see the same rate of expansion in all directions.
Furthermore, dark energy is detected by the separation momentum of the galaxies and galaxy groups that are all moving away from each other. The rate of separation is increasing and so the expansion is said to be accelerating. Dark matter is not sufficient to stop or reverse the expansion and in fact if you consider the inverse relationship between the strength of gravity and distance, you would not be expecting that relationship to just turn itself around would you?
And one more thing for the sake of discussion; electromagnetic radiation. The cosmic microwave background is almost perfectly isotropic meaning that it is measured at approximately the same 2.7 degrees everywhere. That means that all space created since the Big Bang has to have this 2.7 degree background. If the dark matter were to be the force that pulls everything back together, how could this radiation that is traveling at the speed of light in all directions ever be pulled back into a final big crunch before the annihilation causes the next crunch. It couldn't.
So each time you have a bang/crunch, some of the energy is irretrievable and some of the space that was created would remain out there to contain that un-retrievable cosmic microwave background energy. Eventually, given that each cycle loses some of its energy to this irretrievable background and what would be a greater and greater un-reversed inflation of space, the whole cycle thing would run out of gas so to speak. At some point the bang/crunch will fizzle into a pfffft, IMHO.
Are these comments what you were looking for?

quantum wave, your forever expanding theory would have been right if not for Weakly Interactive Massive Particles clumping effect.

Although WIMP produces very weak of a force, with many WIMP particles this force becomes much greater.
A theory: what if every interaction of regular matter in the universe produces a WIMP particle as a sideffect.

I think of them as dark matter. Clearly something like them exists and the question is where do they fit in the process of particle formation. I put them there right at the beginning of matter formation and think of them as instrumental in the particle formation process. I also see them as abundant and dominate at the earliest phase of particle formation and think their role includes that of pre-particle in the process of building particles with charges that interact with electromagnetism.
I also think of them as abundant left overs when the period of fundamental particle formation is complete and having a lasting effect in and around galaxies and a diminishing effect in the space between galaxies. Admittedly these are my own views and I'm not claiming to be right about them.
In my view they feel and exert gravity.
