Could the Big Bang be related to the flow of current in vacuum tubes?

[Dryson]

Taken from another post.

The Universe was so hot immediately after the Big Bang, nothing but energy could exist -
Current can only flow in one direction through the device between the two electrodes, as electrons emitted by the hot cathode travel through the tube and are collected by the anode.

http://en.wikipedia.org/wiki/Vacuum_tube
Since the Universe was very hot after the Big Bang could the area where the Big Bang occurred be considered the device where the initial point of the Big Bang occurred and the leading edge of the Big Bang be the other electrode where current flowing in only one direction where electrons emitted by the hot cathode or in this case the actual Big Bang would travel through the Universe where they are collected by another process or the anode to form into early energetic bodies in space?

I'm trying to understand the process of the Big Bang by using devices that we have created that in theory should also be related to how the Universe functions.

The big bang "happened" all throughout space at every point, there is no direction in which it "flows" or "moves" and as such there is no "leading edge". I don't see the analogy you are trying to draw at all.

 

[Dryson]

Leading edge is a term that applies to the furthest point of the expansion from the central source of the Big Bang. Just like the inflating surface of a balloon has a leading edge from the central source of where the exact center of the balloon would be located.

Also to say that the Big Bang ignited the points in space all at once would be say that each solar system had been predestined and prepositioned prior to the Big Bang where the Big Bang caused each celestial position to ignite into being.

If the Universe is expanding then the leading edge would be the furthest point from the center of the Universe to the furthest most point at the perimeter of the Universe where energy is still expanding outwards.

There is no "central point", nor a "leading edge" for the Big Bang. There is no "center of the universe" as far as we know, that is the basis of the Copernican principle, which is one of the fundamental principles upon which modern cosmology is built. The big bang was not some explosion that occurred at some point and propagated outwards, it "occurred" at every point in space (occurred is bad terminology since the big bang is a singularity and is actually more like "the origin" of every point in space).

The center of the balloon is not a part of the balloon's surface geometry. If you're thinking of the 'balloon analogy' of the expanding universe this way, that's not how it's meant to be interpretted. The universe is represented by the surface of the balloon only, and all of the surface is there from the beginning - it just expands, and distances 'in the universe' (on the surface of the balloon) grow larger.

indeed, and as I have seen on this forum on a number of occasions
You are at the centre of your observable universe ( regardless of where in the universe you are )

That furthest point is in the distant past. Are you trying to project it beyond t=0? That does not work very well.

Greetings. Please remember that there are "places we cannot go... things we cannot measure" yet and those include anything prior to about 400,000 years AFTER the Big Bang, due to the Universe being opaque prior to that time. We can extrapolate some data down to Planck Time - 10^-43 seconds but prior to that absolutely nothing is known or can be known until and unless we find something to measure (Gravity maybe?). This is further complicated by the apparent fact that the further back we go 4 fundamental forces becomes 3, then 2, then 1, so we don't even know how far some means of "seeing" gravity will take us.

Bottom Line = past a certain point we can do no Science yet. All there, is speculation, worth less than a sharp stick in the eye... which is apparently less painful than the job of Quantum Gravity guys.
