If a second big bang occurred at the centre of our universe what would happen?

Question

Assume a second big bang occurred in the centre of our universe. The rate of expansion is equal to that of our universe.
(a) would the expanding second universe destroy all in its path or push our universe out without destruction.
(b) if it continued to expand and intelligent life evolved would the occupants of the second universe be able to observe us - I assume not.
(c) would we be able to see it as the expanding second universe approached us. Or if the rate of expansions of both universes was equal would we be completely oblivious of its existence.
(d) Forgetting the problem of actually observing each universe would it be possible to travel between the two.
(e) How would the situation be different if, instead, two big bangs occurred in the centre of our universe within a relatively short distance of each other.

Answer 1

were all gonna die.argghh

Answer 2

I don't think you fully understand the big bang theory. The second part to that theory is the "big crunch" The universe is currently expanding (hence the red shift in other objects such as stars and other galaxies) and will eventually slow down and reverse its momentum. The big crunch is exactly the opposite of the big bang, all the matter in the universe will come back together in the same single point that it was created. It would be impossible for a second big bang to occur, there would not be enough mass compacted into a single point for that to happen anywhere in the universe. There can only exist one universe within one universe, not two. Yes, there's the possibility of parallel universes, but thats a different story.
To correct the guy above me about if the suns explodes then its the end of the universe....you could be farther from the truth. Astronomers see stars go supernova every single day and it has no affect on the universe except for the surrounding area of the star. Depending on the size of the star, after it explodes, its remnants could be the stuff that causes a new star to be born. Or it could be a dwarf star and just be hanging out in the vastness of space doing nothing.

Answer 3

Interesting question. If another Big Bang happened with our our Universe I have no idea what would happen. Given the technology to travel at galactic speeds would we be able to cross the barrier, given that there is one. Also, the energy of the beginning of another Universe, would be intolerable especially if it happened near us.

I really see no reason why there is only one Big Bang. There may be infinite singularities in various out there exploding into nothingness.

The Big Bang does not necesarilly beget the Big Crunch. In fact it seems rather silly considering new evidence to the contary. The big Bang has been a well known theory but there has always been alternate theories,

There is a centre of the Universe. Its where everything happened that has led up to now. when we look back into the begining we are looking to the explosion at the centre of our creation. Our sun is a second generation star and the Earth was not here until about 4 billion years ago far distant in time from the beginning of the Universe about 15 billion years ago.

Answer 4

If there was a second big bang I believe what would happen is that the center explosion would in turn cause our universe to expand at a higher rate and what occurred after the first big bang would occur in the center of the growing universe (in other words evolution would take a second turn). No matter where we were located we would be oblivious to the surrounding expansion unless the center universe caused the entire universe to expand so quickly that our scientists would notice the difference in our own galaxy (milky way). For example a sudden drop in temperature because we would be moving farther away from the sun. Yes I believe we would be able to travel between the two if the second center of the universe wasn't expanding too dramatically to create and affect other planets/galaxies.

If two big bangs occurred then they would probably and eventually get in each others way and their combined energies would mimic a supernova and create a giant black hole that might (although I'm not quite sure to what extent) swallow neighboring planets and maybe even galaxies according to the black hole's size. It would be impossible to say this and be 100 percent sure but according to my research and my own theories of the origin of the universe I believe the black hole would be the outcome of two nearby big bangs....but to what extent the following destruction would be I have no idea....all I can say is that it would not be pretty!!!

Answer 5

There is no "centre of the universe", so you can't conjecture something happening at a place that doesn't exist.
The big bang was the creation of everything, including space and time. This universe's space and time would be completely disconnected from out own, and therefore, if another big bang were to happen somewhere in out universe, the answer is, from our standpoint, nothing. In fact, some theorists including Stephen Hawking postulate that big bangs are happening all the time. Right now, deep inside your liver a kazillion universes came into existence while you were reading this... but of course, that cannot be proven, so your liver is safe.

Answer 6

there wont be a second big bang because there was not a first one colliding galixies disprove the big bang as the universe creative forcedue to the billions of billions of light years that it would take for a galixy to do a 180 degree turn and collide with another big bangers also think the universe is only 13.8 billion years old thats far to young to account for galixy collition to occur from a single point of origin.
a= the universe is everything that exist every where all the time there would not be an expanding second universe only an explosion somewhere in the existing one.
b=if life evolved from that explosion yes they may see us
c= we might see it like we do a supernova but only if its close enough.
d again it would not be two universes it would still be the same one.
e=technically matter would be comeing from more than one point of origin much like the way it is now.

Answer 7

According to current theory this assumption is meaningless. We can not assume something that can not be. Another big bang can exist next door to us. There might even be innumerable big bangs going on right now and there is no way of knowing this. Just that the theory allows for the possibility. The physics can be exotic and specific to each universe. But that means that our physics and that includes us too will not be able to exist in another universe.

Answer 8

In about 5 million years the sun will implode and will destroy the universe as we know it (sucks a bit for those around then!). However, the particles that will scatter after this will be the foundations for another universe.

Pretty sure there was a recent article on this (try BBC website?) but in summary there is no way the universe can explore/implode etc and the Earth survive.

On the plus side, we won't be around to deal with it!

Answer 9

--The real question should be: Did the big bang theory happen as the evolutionists said it occured?

--That premise has not come to any conclusion!
Please note:

*** g96 1/22 p. 4 What the Big Bang Explains—What It Doesn’t ***

Professor Fred Hoyle likened the efforts of the Ptolemaic cosmologists at patching up their failing theory in the face of new discoveries to the endeavors of big bang believers today to keep their theory afloat. He wrote in his book The Intelligent Universe: “The main efforts of investigators have been in papering over contradictions in the big bang theory, to build up an idea which has become ever more complex and cumbersome.” After referring to Ptolemy’s futile use of epicycles to rescue his theory, Hoyle continued: “I have little hesitation in saying that as a result a sickly pall now hangs over the big bang theory. As I have mentioned earlier, when a pattern of facts becomes set against a theory, experience shows that it rarely recovers.”—Page 186..........
.......A major challenge to the big bang has come from observers using the corrected optics of the Hubble Space Telescope to measure distances to other galaxies. The new data is giving the theorists fits!

Astronomer Wendy Freedman and others recently used the Hubble Space Telescope to measure the distance to a galaxy in the constellation of Virgo, and her measurement suggests that the universe is expanding faster, and therefore is younger, than previously thought. In fact, it “implies a cosmic age as little as eight billion years,” reported Scientific American magazine just last June. While eight billion years sounds like a very long time, it is only about half the currently estimated age of the universe. This creates a special problem, since, as the report goes on to note, “other data indicate that certain stars are at least 14 billion years old.” If Freedman’s numbers hold up, those elderly stars would turn out to be older than the big bang itself!

Still another problem for the big bang has come from steadily mounting evidence of “bubbles” in the universe that are 100 million light-years in size, with galaxies on the outside and voids inside. Margaret Geller, John Huchra, and others at the Harvard-Smithsonian Center for Astrophysics have found what they call a great wall of galaxies some 500 million light-years in length across the northern sky. Another group of astronomers, who became known as the Seven Samurai, have found evidence of a different cosmic conglomeration, which they call the Great Attractor, located near the southern constellations of Hydra and Centaurus. Astronomers Marc Postman and Tod Lauer believe something even bigger must lie beyond the constellation Orion, causing hundreds of galaxies, including ours, to stream in that direction like rafts on a sort of “river in space.”

All this structure is baffling. Cosmologists say the blast from the big bang was extremely smooth and uniform, according to the background radiation it allegedly left behind. How could such a smooth start have led to such massive and complex structures? “The latest crop of walls and attractors intensifies the mystery of how so much structure could have formed within the 15-billion-year age of the universe,” admits Scientific American—a problem that only gets worse as Freedman and others roll back the estimated age of the cosmos still more.

Answer 10

First of all, the center of the universe IS the universe.

Answer 11

iit would probably do everything differently. it was a lucky chance( like a one-inch-to-ither-side chance) that this happened. also, the univers would have the "big crunch" first.
