    Origin
In summary, the conversation discusses the concept of finding the first cause that created the universe and the question of its own origin. The idea of causality is brought up and whether it applies to the first cause. The conversation also explores the existence of the number 3 and its relation to the universe. The question of whether causality applies to the first cause is discussed and it is noted that science cannot address the concept of eternal existence.

Hi all,

Suppose we find the first cause that created the universe. What about the origin of this very first cause? Suppose it is X. What about the origin of X? Suppose it is Y. What about Y? And so on...

Can we ever find the origin of this universe?

Why do you expect that the "first cause" has to be caused by something? Causality is a statement about processes in our universe.

A related, tricky question: Do you think the number 3 exists? Does it need a cause to exist?
Let's say we find some way to relate our universe to the number 3 in a mathematical way. Does our universe need a cause to "exist"? Does it exist at all?

Are we talking about science or 'magic' where things happen without any cause.

If the 'first cause' happened without any cause, what is the surety or proof of its existence?

Neither. You are discussing a well-traveled topic in philosophy. Science cannot address the question of eternal existence because it is an unfalsifiable proposal.

Sorry. This is Philosophy, and we don't discuss that on PF.
 

1. What is the Big Bang Theory?

The Big Bang Theory is the prevailing scientific explanation for the origin of the universe. It proposes that the universe originated from a single point, known as a singularity, and has been expanding and cooling ever since.

2. How was the Big Bang Theory discovered?

The Big Bang Theory was first proposed by Belgian astronomer Georges Lemaître in 1927. It was then supported by observations made by American astronomer Edwin Hubble in the 1920s and 1930s, which showed that distant galaxies were moving away from us, indicating an expanding universe.

3. What evidence supports the Big Bang Theory?

There are several lines of evidence that support the Big Bang Theory. These include the cosmic microwave background radiation, the abundance of light elements such as hydrogen and helium in the universe, and the observed expansion of the universe. Additionally, the theory has successfully predicted and explained several observed phenomena.

4. What happened in the early stages of the universe's evolution?

In the early stages of the universe's evolution, the universe was extremely hot and dense. As it expanded and cooled, particles of matter and antimatter annihilated each other, leaving behind a small excess of matter that eventually formed into the first atoms. These atoms then clumped together to form stars, galaxies, and larger structures.

5. Are there alternative theories to the Big Bang?

While the Big Bang Theory is the most widely accepted explanation for the origin of the universe, there are alternative theories that have been proposed, such as the Steady State Theory and the Inflationary Theory. However, these theories have not been supported by as much evidence as the Big Bang Theory and are not as widely accepted by the scientific community.
