This is all based on some thoughts this article gave me.

Assertions

  • The big bang theory is currently accepted theory about the origin of the universe
  • Infinitely dense implies some kind of material (I avoid the term matter intentionally) - think of it as the fabric the universe is made of (irrelevant what it is at its core)

Question

If the point was indeed infinitely dense it would suggest that it never runs out of whatever that material is that defines its density, right?

From that viewpoint it would seem to be logical that the universe will keep expanding and expanding as the ("spatial") origin never runs out of the material the universe is made of, right?

So doesn't the big bang theory as it stands imply the ever-expanding universe outcome?

I wonder, because there is still no consensus about it in the scientific community, it seems.

Remarks

Now I am aware that the physics of the beginning of the universe is theoretical and oftentimes beyond comprehension, in short: mind-boggling. This is why I came up with that question.

I'm just wondering whether one cannot automatically deduce one (ever-expanding universe) from the other (infinitely dense point at origin of universe)?

Or is my fallacy the one that the infinitely dense point refers not to the fact that the amount of material $x$ at that point is $\infty$, but rather because the space of a point is $0$? So because of that it doesn't matter whether $x = \infty$ at all? ...

The term "infinite" when used in this context simply means incalculable. It is not suggested that the origin "point" was actually "infinitely" dense, merely that there is currently no way to mathematically theorize with any accuracy exactly how dense all the energy and matter of the universe would be if compressed to a single point. Infinite is much closer to a reasonably accurate description than "really very dense" and plus; it sounds way cooler.
