If they exist why can we not see them? Is it because light requires gravitationl filelds and elromagnetic fields in order to be able to transverse space and the void that these universes exist in has no such fields? Or could it be that they are so far distant that light from them has not yet reached us? The big bang theory states that time and space came into being at that instant. Do you agree that space contains gravitational and eltromagnetic fields because of the condensation of energy into matter and the activity of this matter generated these fields? Is it not logical to believe that at one point there was absolutely nothing in existance and something came into being from that nothingness? If not, how else could it have been?

yes,there are other universes. it comes straight out of the theory of quantum mechanics, a set of mathematical rules that describe how the universe works on the smallest scales, inside atoms. Quantum mechanics says that matter and energy can appear spontaneously out of the vacuum of space, thanks to something called a quantum fluctuation, a sort of hiccup in the energy field thought to pervade the cosmos.we cant see them because light from those extremely distant realms hasn't had time to reach us.

First let's dispense with the fallacies. Light does not require a gravitational field. Light is the propagation of an electromagnetic field. The "observable universe" is that part of the universe close enough so light had time to reach us. We therefore have no good way of knowing what's beyond the observable universe, but we expect there's still some universe beyond the observable. Big bang theories do not necessarily state that space and/or time came into existence by the same process, but they don't rule it out either. All the space we know about contains gravitational and electromagnetic fields. We know that a gravitational field (or a warping of spacetime) exists in the presence of matter, an electric field exists in the presence of charge, and a magnetic field is probably just the relativistic aspect of a changing electric field. But we don't know why all this is true or why these forces have the properties and relative strengths that they have. All of the multiverse theories I've heard of (outside of fiction) require a separation by more than just 3-dimensional space or time.

Big Bang is an extreme extrapolation of current observations back into time, confirmed somewhat by simulations and theoretical 'what if' calculations. If this was the state of the universe at age 4 nanoseconds, then given the laws of physics as we understand them, the current universe could have resulted.

Try as we may, we can't extrapolate beyond that theoretical convergence point, that apparent singularity. Science really can't say what was 'before' then, or if that concept is even meaningful. That no matter or energy, or even spacetime, predates the big bang is just as valid a hypothesis as any other. To postulate that the big bang resulted from the intersection of M-brane manifolds just pushes the question farther back. Where did the branes come from?

I assume you mean other universes that started with their own big bangs.

The light we see with travels over time through space. The spacetime in our universe is probably closed and unbounded, so there is no way for it to get in or out of it. If there were another universe, it would also be closed and unbounded, and disjoint from ours (google that). An analogy would be two separate closed loop race tracks where the track is the "universe" and the race cars are things in it (like photons). You can go around and around either one, but you cannot get from one to the other.

It's like the joke about the guy that stops at a gas station to get direction to some small town. The guy says, "Well, you go north on County Road 65 about 5 miles and turn west on ... No, go *south* on 65 about 7 miles and ... No. You know, what? You can't get there from here!

well, to see other universes, it is not the concept of light or any such Field...the universe is vast, huge or rather infinite and there are parallel universes within universes...so overall, the statement is like as if there is millions of infinity within a single infinity which lies in one of the millions of infinite universes...

So the concept of light and Fields is not valid here...The only thing is that you need to establish something related to time, the fourth dimension...It is quite probable that the only difference between the universe is marked by time limits which marks the maxima and minima energy level which an entire universe can hold...

So probably, you can see "other univeses" if you could travel time, which is certainly not realistic till date...

Our Cosmos consists of many universes. The Cosmos itself is still growing and getting larger! We are getting farther and farther away with passage of time! Everything in the cosmic system is measured in terms of light... the distance light travels in one year is called a light year! Light does not require even two seconds reaching moon and mankind has its limitations! We have not been able to travel out of our solar system... what to say of visualizing the whole Cosmos even by the best telescopes!

Science has its limitations... with passage of time our discoveries and inventions are speeding up! Maybe at a certain stage in future we catch up with the distant universes... How many years from now we do not know! Travel from one universe to another is totally prohibited by God Almighty... the prime reason why science has its limitations! Who knows in what form one reaches the stage of enlightenment in another universe... maybe it is the form of a cobra! In the circumstances how would one distinguish between the alien Cobra and those manifesting our planet?

Every soul atman within the gravitational pull of solar system remains confined in the solar system until a human being reaches the stage of enlightenment (kaivalya jnana) and finally salvation (moksha). Only then the soul atman within finally liberates and steps into the kingdom of God (aka Baikuntha in Hinduism). The moment a soul atman regains its original pure pristine form... it becomes free for cosmic travel. This liberated soul atman can travel to any part of the Cosmos in its prime pure state (not in bodily form)!

Contrary to what many people believe... nothing came into existence from nothing! Yes, the size of the Cosmos at one stage was the size of half a thumb! When the dissolution of a cosmos occurs... the dissolved Cosmos reduces to the size of half a thumb! And what is this half a thumb? The entire cluster of purified souls' atmans in the Cosmos combine together to form the size of half a thumb! As per Bhagavad Gita in Hinduism... this is the only definition of God Almighty!

This prime pristine pure power... the combined power of all purified souls atmans in the Cosmos unable to retain itself for long in its prime state again explodes with a big bang causing the formation of a new cosmos... a new cosmic life cycle! Does this mean that in the beginning of the Cosmos God Almighty himself explodes with a big bang... yes, the truth is so! All has been made explicitly clear in the Sacred Bhagavad Gita of Hinduism... the doctrine given to mankind by Lord Krishna in Mahabharata!

When my daughter was younger she aked me about alternate realities, after she had watched a movie. I explained as best as I could, then asked her a question...which side of the mirror are you on? She's 21 and it still freaks her out.

first you must explain what kind of universes if paralell then we have it right here on here but we cant open it because we need strong gravity to flow on both sides to how if it exists because gravity is diffrent from one universe to an other and we have to find a link its superstring theory but you ned some surious thecnology ........sorry i only answard only one question
