Why does the Universe need a beginning

Alright, I know some specific theories like the Big Bang base themselves largely in evidence like the Hubble Redshift, but there's a sense that there's more to the decision than just taking evidence and following it to an inevitable conclusion.

People seem to feel, on some level, that there must be a first event, or that the universe must have a beginning.

My question is why? Why can't it be enough to just accept that it always existed?

Is it sort of an application of the concept of scale? We know the Earth didn't always exist, nor the Sun, and so ..... maybe some people just like to take that logic all the way to the universe itself?

I ask because I just don't share this feeling. I'm trying to understand it, so maybe if I can get inside the heads of people who feel this way... maybe I might even come to agree. Who knows?

Et nous ne sommes même pas un Quanta de lumière, relativement parlant nous ne sommes q'une chose parmi le reste et ce qui nous dépasse... Et bien plus encore.

Because human beeing can't accept to don't know everything

Oh pitin c'est un anglais

L'Homme cherche à savoir le "commencement" car il ne pas pas imaginer (ou accepter) qu'il y est quelque chose qui le dépasse, qu'il ne peut pas comprendre, une question à laquelle il n'aura jamais réponse.

Si nous nous mettions à l'echelle par rapport à notre planète: même notre galaxie serait invisible



Sure: but I just don't fully trust people to look at the concept of "entropy" objectively sometimes. Suppose you put a system in the most disordered state you can imagine. Left to itself, I suspect that system might begin to become more orderly instead of less. For me, the third law is replaced by a belief that all systems seek a certain amount of order/disorder. A balance.

Look at the way nuclear physics work. You can split an atom and get energy if it's larger than Nickel or Iron. You can fuse it if it's smaller. We have this arbitrary size of atom that doesn't yield energy no matter what you do to it. So, it's not always about splitting or fusing. I think nature is full of such situations.

Basically, if you believe the 3rd law adamantly, then you have no choice but to utterly reject the theory of evolution as being a contradiction of the laws of nature, because it would represent an example of a situation where lesser order moved spontaneously toward greater order.

I believe that there is no end and no beginning. Things just exist. Because if you say : "there is a 0 point, where everything began" (the big bang, the creation), I ask : "and before, there was what ?"

I suppose that the big bang existed.. But what before ? I think that the thing that existed before existed for an infinite time.

Ce n'est qu'un pet!

Que j'aime cette idée de comparer l'univers à une flatulence

Man sees everthing as having a begining and an end, he tries to make everything black and white, he cannot understand that these are only words he makes and thus when questions like "when does life begin" come up he has no answer because it does not conform to his belief that everything has a begining and an end, whereas in reality there is no begining and no end merely transitional stages. An embryo is a transitional stage between a pile of scattered materials and a life, same for aeroplanes ships etc.

In the same way, I believe the universe had no begining it will have no end, the big bang was a transitional phase which led to what we have now, but what it came from or how it came from it we do not know

Effectivement Seth! D'autant plus que derrière et au delà de cette flatulence, l'image est d'autant plus agréable et intéressante! Si on considère que le Big Bang est une flatulence, moi je pause la question pour faire chier le monde : Vi mais c'est qui ka péter!?

C'est moi

@DivideByZero :

I'm ok with that. "Beginning" and "End" only take fear away from our hearts (or it is supposed to...) but in the real life they only exists as "concept". As I believe that life is the couscious transitional phase of the whole concept of "being" and "non-being", big bang is the beginning of the transitionnal phase of the universe where it has the physical existence we can see. What was before is certainly out of our possibilities of understanding (and even of our capacity of conception), and does not have a real interest anyway.
