Welcome to episode three of the Metaphysics of Physics podcast. I am Dwayne Davies, your host, philosopher in chief, writer and guide through the hallowed halls of the philosophy of science.

Ashna
And I am Ashna your co-host and fellow guide.  Thanks for tuning in everyone!

Dwayne
With this show, we are fighting for a more rational world, mostly by looking through the lens of the philosophy of science.  We will raise awareness of issues within the philosophy of science and present alternative and rational approaches.

Ashna
Yes, and today we are going to briefly discuss the concept “universe”, the Big Bang and some of the philosophical issues surrounding these two ideas.

Ok, let’s get into it.

What is the Big Bang? It is a physics theory which explains the origin of the universe as we know it.

It should be noted that despite the name of the theory, the theory does not assert that there was an explosion which created the universe. Rather, it refers to a rapid expansion. A rapid expansion of what? Rapid expansion from something known as a singularity.

Big Bang explosion

No, this is not what the Big Bang theory states.

Ashna
This singularity is supposed to be a point of infinite density, isn’t it? Isn’t that just nonsense?  What does it mean to have infinite density? Presumably that this point had no volume?

Dwayne
Indeed. But, we are not going to dwell on this very much. We are not here to discuss the physics of the Big Bang.

Ashna
Yeah, so let’s get started with the concept of existence…

Existence exists. With that statement, I have stated the most fundamental fact that there is. Upon this statement, all cognition depends.

Now, suppose that I was to assert that there is nothing that exists. The very fact that this statement can be made, proves that something exists to make the statement. The axiom of existence is completely immune to refutation and any attempt to refute it, merely shows that it is true.

There is no alternative to this basic fact. Entities exist, and there is no way to imagine any alternative. Even were you to attempt to imagine an allegedly empty void of nothingness, the supposed perception of it requires an entity to perceive it, and something to perceive.

There is no way to perceive or think about non-existence. To perceive is to perceive something. That which does not exist cannot be perceived.  There is no way to imagine non-existence. To think is to think about something.

  1. “There is no way to perceive or think about non-existence. To perceive is to perceive something. That which does not exist cannot be perceived. There is no way to imagine non-existence. To think is to think about something.”

    There is always polarity. Existence must have an opposite in order for itself to exist. I know that sounds rediculous but so does dark matter and anti-matter.

  2. No, existence does not need an opposite for itself to exist.

    What could possibly qualify as an alternative to existence? For it to be an alternative to anything it must first exist. And if it exists, it is part of existence and therefore it cannot be an alternative to existence!

    Unless you mean that for existence to exist one must be able to imagine an alternative. But, you cannot imagine an alternative to existence. There is nothing to imagine or even conceive of. The imagination of non-existence is a contradiction in terms.

    Even if you could imagine it, existence exists regardless of the content of your mind, including your imagination. As evidenced by the fact that the universe existed long before there were beings capable of imagining anything!

    Some things do have an opposite. But the existence of something does not necessarily require the existence of an opposite. Nor does the fact something exists necessitate that its opposite must also exist.

    Existence is not even a physical thing. It is a concept which subsumes everything that exists. It can have no opposite since everything that exists comes under the concept of “existence”.

    Furthermore, not all concepts or physical things have opposites. What is the opposite of a book? Not a book? No. What is the opposite of a person? Not a person? No. To have an opposite means that there exists something with similar qualities that exist on different ends of a scale of measurement or viewpoint. But, this does not apply to some physical objects or concepts and most certainly not to existence.

    The claim that there is always polarity is therefore without any basis and logically invalid.
