Theory Proving Everything Has a Beginning?

    Theory
In summary: It is a bonafide scientific theory. It explains some of the things that big bang does not. So if you want to dismiss it, that's your business, but it's not based on anything objective.PeteIn summary, there are several theories in physics that suggest everything has a beginning, such as the Principle of Causality and Aquinas's "Prime Mover". General relativity also states that the universe began from a singular state, known as the big bang. However, the exact name of the theory that proves everything has a beginning is uncertain and there is ongoing debate about the pre-big bang theory.

I heard there is a theory in physics that proves that everything has a beginning. Is this true? If so, does anyone know the exact name of the theory?


Any help is appreciated.

Perhaps you are referring to the Principle of Causality, which says that every physical event (including the existence of a physical object) is caused by some other, prior event. That's if you're talking about each "thing" individually.

If you're talking about "everything" as a whole, then you probably mean Aquinas's "Prime Mover"*, which is generally considered to belong more to the realm of philosophy than physics.



* frequently referred to hear in the Forums as, "LifeGazer's primary cause argument".:wink:

General relativity says that spacetimes satisfying certain physically reasonable assumptions must have begun a finite time ago in a "singular" state, that is, a state that can't be described by general relativity. It's thought that our universe arose from such a state via the big bang.

Everything has a beginning (a source) also in Eugene Savov's theory of interaction. He reduces the physically reasonable assumptions to the pure fact of existence. For details you may see the free sample chapters download at http://www.eugenesavov.com

That's not quite right. The Big Bang theory can't go back to exactly t = 0. At that point there's a lot of uncertainty as to the physics at that point. There is a theory that states that something came before the big bang - it's called the pre-big bang theory.

Yes, this is correct. Nonetheless, the phrase "a finite time ago" is the one used in framing the singularity theorems, and I was only trying to indicate that for this reason, GR may have been the theory that the poster was looking for. But again, your statement as I've quoted it is of course correct.

If causation breaks down, then so does the notion of "before": Pre-big bang theory is more ill-defined idea than bonafide scientific theory.

Nothing about pre-big bang violates causation - so why do you bring it up?
 

What is the theory that everything has a beginning?

The theory that everything has a beginning is known as the "Big Bang Theory". It proposes that the universe began as a singularity and has been expanding ever since.

What evidence supports the theory of a beginning for everything?

There are several pieces of evidence that support the theory of a beginning for everything. These include the cosmic microwave background radiation, the expanding universe, and the abundance of light elements in the universe.

Is the theory of a beginning for everything widely accepted?

Yes, the Big Bang Theory is currently the most widely accepted explanation for the origin of the universe. It is supported by a vast amount of scientific evidence and is the cornerstone of modern cosmology.

Can the theory of a beginning for everything be proven?

No, the Big Bang Theory cannot be proven definitively. However, it is the most widely accepted and supported explanation for the origin of the universe based on current scientific understanding.

Are there any alternative theories to the Big Bang?

Yes, there are several alternative theories to the Big Bang, such as the Steady State Theory and the Oscillating Universe Theory. However, these theories do not have as much scientific evidence supporting them as the Big Bang Theory does.
