The idea of universe you speak of from the big bang onward is actually better called the 'time space continuum' and is there something outside,
well most top physicists actually believe there is the name they give this outside space is usually superspace, now the term universe apply's more
accurately to all of this.
Let's look at the big bang a moment as you mentioned time, Well the big bang is a belief that the whole universe began from one sudden explosion of
energy into the nothingness? that surrounded it, does not really make sense doese it.
SO what is a big bang, there are ideas that a primal point of matter exploded now what would that point actually be?
In quantum theory there is a belief that of all the forces native to our own continuum gravity and time may be the weakest, gravity is for example far
weaker than electromagnetism, millions of time's weaker and some quantum physicists believe it may originate from somewhere else in superspace.
There is a theory called membrane theory, now it will be hard to percieve but imagine our universe as a flat sheet drifting in superspace and somehow
it collides with one or more other sheet's called membranes, the interaction between these membranes creates ripples on our sheet.
Now imaging that instead there are three sheet's that are lying together, one is where gravity comes from and our sheet like a sheet of blotting
paper on a wet cloth has that gravity soaking through it, the other is where time and energy come from and lies on the other side of our sheet from
gravity so we are in between and indeed out universe may only exist as that, a interaction between these two other sheet's.
So that would mean gravity is everywhere right, like at a universal constant so how does matter have more gravity than empty space, well it has to do
with the fact that matter and empty space are made of the same thing, matter is like the sheet or let's call it string for now, rippled up and held
in a tangle, the denser the matter is the more of this sheet or string there is in a given volume so since the gravity is coming through that sheet
equal all over it then were there is more of it in less space there is obviously more gravity.
Now Time, well as gravity can be held in less volume the time may come from the other sheet and gravity pull's on it slowing it while it tries to
flow the other way back to it's own membrane, we see this as causality action and reaction but dense gravity does strange thing's to the way time
flow's or is perceived to flow from a point observing such as in einsteins relativity.
Look at a solid base ball in your hand, now imagine there was no other matter, were is the mass if you are at the centre of it? Yes it is all around,
now that means all that scrunched up space is all around that point and therefore all the gravity must be pulling outward on a tiny point at the
centre of the base ball in all directions equally but the pressure keeps that point really really small.
Now let's scale that up a little to, oh let's say a blue supergiant bigger than betelgeuse (a giant star) and imagine that the star has reached the
point were there is insufficiant hydrogen left to maintain it's fusion to mass ratio and so it collapses under it's own weight, but wait a minute
there what about that tiny tiny point at the centre - well it get's crushed smaller and smaller but as the star collapses lets say it becomes what we
call a black hole.
A true black hole is a peculiar object as it's mass equals the universal constant so it is as heavy as everything else in the universe combined
(regardless of the mass of the star is it has collapsed into the source of gravity.)
Now around the exterior terminus of a black hole is a region called a event horizon and long before anything reaches this point he fabric of the
universe is pulles so taught that it litterally gets pulled out of existence, now the region just above a black hole event horizon may be called a
grey whole by some but the black hole can still exist beyond that point so light outside an event horizon could be stuck but if it passed into an
event horizon it would cease to be.
Now let's go back again to that little tiny point, well suddenly as small as it is the point is pulled by a near infinite gravity outward in all
directions and as it is essentially now an isolated piece of the universe it becomes inverted at it's centre and the other sheet opposite from the
one the gravity comes from is pulling into infinitisimally short contact with the gravity membrane through this inversion, the result is that in this
tiny point the gravity touches the other membrane and it explodes with universal force into that point, now another even horizon exists in a black
hole, the one around that tiny tiny point.
So there is a big bang and it happened inside a black hole inside a univese with probably the same law's of physics but relative to the outside
univers time in the new one would move at first much much faster, the rupture of the inversion lasts for only the briefest instant and the gravity of
the surrounding black hole still tugs at the new universe, so no need for dark matter then, also the asymetry of the universe where there are clumps
of matter and energy place oddly can be explained like this, the black hole that triggered the white hole (white hole is the same as big bang) and the
formation of the time space continuum was actually spinning very very fast and the point at the exact centre was also uncertain as to is own exact
centre while the gravity vortex lensed at it was pulling with some varience.
Now how doese time behave, well I have difficulty with the concept of then, now and when, for me time is a cone and parrallel reality's exist at
varient to each given point of refference like a cone moving outward and back, there are mathematics but I do not count the numbers in standard linear
equations so would have great diffictulty framing it thus, suffice it to say I see them.
Now bear in mind this is only my idea but is based on good factual information and theoretic hypthesis.
So yes there is something outside the univers but by definition that is still the univers so what is outside that?.
