Reply to point 1) I thought that gravity pulls things together. My old science teacher has said that if you had an empty universe and put two pencils on oposite sides of the universe they would move twords one another, not away. And all that proves is that there is a core to the universe, not that there was some explosion or rapid expansion of very hot gasses.
I'd like to offer a different perspective from the suggestion that the pencils would have had an initial acceleration away from each other, but I'm still going to keep it simple.
While the pencils *would* experience a gravitational attraction, even when positioned on opposite sides of the visible universe, that attraction would be easily overcome by the expansion of the intervening space. In other words, the space between the two pencils would be expanding more rapidly than gravitation could pull them together.
As the pencils become increasingly far apart their gravitational attraction will continually diminish, and the expansion of space will carry them ever increasingly further apart. At some point the pencils will pass out of each other's observable universe and will no longer experience any gravitational attraction. This happens because the influence of gravity travels at the same speed as light, but once the pencils are far enough apart they will be receding from other at a rate greater than the speed of light.
This doesn't violate relativity, which holds that nothing can move through space faster than the speed of light. That's because the perceived relative motion of objects on opposite sides of the visible universe is not due to motion through space, but to the expansion of the intervening space.

Something can't come out of nothing. It is a law of science.
You're probably thinking of laws like "matter can neither be created nor destroyed" and the law of conservation of energy.
About the "matter can neither be created nor destroyed" law, this isn't a scientific law, and in fact, it's wrong. Matter can be destroyed by converting it to energy, where the amount of energy E produced is equal to mc2. Energy can also be converted to mass, but it's very difficult to create the necessary conditions.
It also turns out that empty space is not really empty. As we now know from quantum theory, all of space is seething with virtual particles that flit in and out of existence. This process doesn't violate conservation laws because the particles form in equal and opposite pairs. For example, an electron and positron can spontaneously appear from out of seemingly empty space. This was theoretically postulated before being confirmed with the observation of the Casimir effect, which you can look up at websites like Wikipedia if you're interested.
There are at least several theories for the origin of the matter and energy of the Big Bang, but it cannot be considered anything close to a settled issue at this time. But that the Big Bang happened there can be no doubt. It is confirmed by several lines of independent evidence, and we can discuss those if you like.

Hi Buz,
You and I have already gone around and around on this topic. Give someone else a chance.

Buz, we've done this before. I could never hope to match Sylas, and even he gave up on discussing this topic with you. See thread What's the Fabric of space made out of? to refresh your memory.
Thanks for the link, Percy. I just reviewed the entire fabric of space thread, notebooking some significant statements on both sides of the debate. From my perspective of the review, the thread was very informative to all due to the questions and points I raised, especially to any laymen reading it. Isn't this what forums are for? I didn't see it as Sylas giving up discussing the topic perse. I see it as the topic running it's course. Like all threads there comes a time when we all gave up debating our counterparts.
That thread pertained to the definition of space. This thread has a lot to do with how the properties of space or lack of same apply to the BB topic. Thus my response to your statements relative to the topic question.
Imo, the only argument anyone has that the BB is not scientific as per the topic is that space is static. If this can't be done by anyone, there's no argument here in this thread. To debunk the BB as scientific it must be shown that it is such things as particles and other matter in space that reposition by moving out from one another causing the increase in distance between them rather than space itself expanding. After reviewing our debate in the other thread, I was unable to find anything empirically refuting space as being static and boundless. Sylas's definition of space pretty much boiled down to the only property being geometry of measurements between points. To this I countered to the effect that points are pointless without something existing in space to measure.
space fabric thread writes:
100 Sylas we just don?t know whether space is finite or infinite.
184 buzAccording to the definition of geometry, Sylas, geometry is not a property of space, so your answer to my question is wrong. In an unbounded total space vacuum, there would be no binding properties, no gravity or other forces, and nothing to measure geometrically. Thus, my ongoing contention that there are no properties to space/vacuum to measure or cause expansion. Only when something is introduced into unbounded space/vacuum can anything be observed. Therefore it is only matter, particles and forces, et al which occupy space that can be observed or perceived as expanding, curving or any other activity.
Geometry is an examiner or calculator of space/vacuum relative to that which has been introduced into space so as to occupy space.
187: Percy Space *does* have a geometry. This is from http://www.wfu.edu/~brehme/space.htm:
Like time and matter-energy, it is not possible to define space in terms of simpler physical entities. Space simply exists. It can be defined only in terms of its properties. Those properties are what we call geometry. Two of these properties are the concept of point and the shortest distance between two points.
191: buz This, from your link:
Those properties are what we call geometry. Two of these properties are the concept of point and the shortest distance between two points.
In order to specify points and distances, it is necessary to use material objects.
(italics mine)
There are no points in space until something is introduced into space. Therefore the points, imo, should not be regarded as properties, i.e. consistency/makeup of space itself, but a means of geometric measurement of things in space.
193 Sylas: There are not even points in space then. A "point" is an abstraction, not a thing, used for convenience to talk about space. All our natural laws and mathematics and so on are abstractions, used to help give a description of how the world works.
A "point" is an abstraction, not a thing, used for convenience to talk about space. All our natural laws and mathematics and so on are abstractions, used to help give a description of how the world works.
197 buz: Logically, points are not something that exists apart from matter, energy, et al. They are not properties of space, but math mechanisms existing in the minds of people (people existing in space) so as to calculate geometric problems/measurements pertaining to things which exist in space.
Points are geometric mechanisms in men's minds. What expands is geometric measurements of that which is observed, existing in space. These geometric measurements exist only in the minds of men. The geometric calculations existing in the minds of men pertain to that which exists in space/area and is not a property of space.
Having posted the above, I'll let the matter rest and resign from this thread unless invited by admin to continue. I may not necessarily have more to add anyhow unless a response is needed on something.

Re: Application Of Alternative Viewpoint
Hi Buz,
Instead of replying to me you edited my Message 100 in admin mode.
Cavediver has expressed an interest in discussing this with you, so I suggest you reply to him.
