Why Does Anything Exist

I’ve recently completed the book Why Does the World Exist?: An Existential Detective Story by Jim Holt. It was quite an entertaining read but also quite unsatisfactory, since I feel it didn’t even come close to giving an answer to the question posed. At most, it provided some interesting examples of philosophical gymnastics such as discussions around if existence might be created by a rule that proves itself.

I think that one of the ways in which the discussions in Why Does the World Exist? were unproductive is that they were looking for a cause of known existence. But it is unclear how cause and effect work, if there is no time. Physics seems to indicate that, before the Big Bang, there was no time; so I think assuming we need to search for a cause might be a fruitless endeavour.

More recently, I came across the article Is There a God? Stephen Hawking Gives the Definitive Answer to the Eternal Question on the popular blog Brain Pickings. In here, I found a few quotes from Stephen Hawking which I find are potentially more enlightening ways to explore the question why anything exists at all:

I think the universe was spontaneously created out of nothing, according to the laws of science.

The moment something was created from nothing would be the Big Bang. An explosion of enormous energy.

The great mystery at the heart of the Big Bang is to explain how an entire, fantastically enormous universe of space and energy can materialise out of nothing. The secret lies in one of the strangest facts about our cosmos. The laws of physics demand the existence of something called "negative energy".

When the Big Bang produced a massive amount of positive energy, it simultaneously produced the same amount of negative energy. In this way, the positive and the negative add up to zero, always. It’s another law of nature.

So where is all this negative energy today? […]: it’s in space. This may sound odd, but according to the laws of nature concerning gravity and motion — laws that are among the oldest in science — space itself is a vast store of negative energy. Enough to ensure that everything adds up to zero.

I like to think of this using a simple equation from Why Does the World Exist:

+1 + -1 = 0

This equation shows that we can create two ‘somethings’ out of nothing, as long as the two somethings balance each other out. One might of course still question: but where did the laws originate from that enable such a creation, specifically the laws of nature. As mentioned above, I think this might be the wrong question to ponder, since there can be no cause and effect without time, and we probably lack understanding (and abilities of imagination) to ponder a state of existence without time.

One thought on “Why Does Anything Exist

  1. There is the Aristotelian and Spinozaist view that the universe is infinite and eternal. If this is true then you are a result of the recombination of eternal matter to produce your form and nature.
