Question from Niki:
Hello there and thanks for being here for us, I mean for us atheists.
I suspect my question has been already asked and answered, but I am not sure which link is the best for the best answer, so, here it is about the origin of matter in space.
I myself have some answers to offer, like it’s been there forever in the past, then I read that some scientists have come to the idea and rejected it, I don’t know exactly why. the other answer would be what Steven Hawking told us, that something can come out of nothing, like empty space containing nothing, and then something pops out of this nothing. in that case i would say that this Steven’s nothing is not my nothing, cos my nothing is really nothing, while his is kinda pregnant with something that the matter popped out of.
So, which link would be the freshest and best to tell me the present state of thought on the origin of matter? Or it isn’t known probably.
The other question has to do with gravity and other forces that are present in the universe, and in the matter itself. What about them, which are they and where did they come from? Probably unknown too.
Tied to this is the question of the moving of matter. I know that matter has never been stagnant in space, once it came out of the big bang. So, the first, original push of the bang, was the one that drove the matter into space. But, for space bodies to be formed, there had to be, and is still there, cos there is no traction of the environment in space, the circular movement of the matter so that it gathered together here and there and formed star or planets and suns.
BTW, does our sun rotate too, together with its planets, and us too with the earth?
Thanks, and sorry if I am too much of a dilettante in the field, but I know much more about Mozart. This minute I am listening to the fourth movement of his fortieth symphony. Delicious. lol
Answer by SmartLX:
You’re very welcome Niki, I have gradually gathered some feedback that our presence has been of use.
Anyway, my main article on the origin of the universe is my response to the cosmological argument, and it raises multiple possibilities. A universe that extends forever into the past is one option, and I know what you’re referring to when you say some scientists rejected the idea, but they didn’t really. I learned that while writing an article on the findings of Borde, Guth and Vilenkin. Something from “nothing” is another valid option, and in my article on that I refer to a book and online lecture by Lawrence Krauss who can explain it better than I can. As you imply, the meaning of “nothing” is slightly unconventional in this context.
The origin of the fundamental forces of the universe are as much a mystery as the origin of the matter in it. Again, they could have existed forever or emerged from nothingness, and that’s just two hypotheses of several. The origin of the universe’s movement isn’t so much of a mystery though, because if everything was moving outwards from a single point in a balanced way then the combined momentum of the universe was zero anyway. In one mathematical sense, nothing changed from when (or if) it started as a dot going nowhere. Spinning motions were largely caused by gravity; if two objects are drawn to each other in space but barely avoid a collision, for example, they will begin to orbit each other.
The movement of the Sun is rather interesting. It does rotate, but billions of years of being dragged upon by its own magnetic field have slowed its rotation until it’s probably turning slower than anything else in the solar system. It also moves around the Milky Way in its own 200 million year orbit. Relative to Earth, the Sun travels roughly in the direction of north, so that our orbit around the Sun actually traces a 3D spiral or spring shape through space. Here’s a simple model.
Enjoy your Mozart. Appropriately for this topic I’ve always loved The Planets suite by Gustav Holst, especially the plaintive, possibly jazz-influenced Venus and the sublime, haunting Neptune. (Look up what “sublime” actually means, folks, and then listen to Neptune while thinking of space.)

The Universe and Everything
Question from Bryson:
So based on scientific evidence the universe at one time began to exist right? Explained by What we call the big bang theory. Another law is whatever begins to exist has a cause right? As in there’s something that begins to exist, there’s a cause for it, it existing being the effect. So if a universe existed, logically there’s a cause. Since the universe hasn’t existed yet, there’s no time/space/energy. Which leads to the conclusion that the cause of this “big bang” has to be something outside the laws of time/space/matter.
Well since only two things fall under this category, one would be a divine entity, the other an abstract object like the number 1 or something. My question is how would something abstract be a cause? I know Stephen Hawking said something along the lines of because of the laws of the gravity, there is no need for a creator because that proves the universe will create itself from nothing. But, of course, after thinking about it, if the universe hasn’t existed yet, that would mean the laws don’t exist yet. Plus, while the laws of gravity are describe gravity, it has no creative power. If put 1 dollar in the bank, and then next week 2 dollars, I can logically and mathematically explain why I now have $3. But, if I put 1 dollar in the bank and depend on mathematics to increase it, I would never have more than $1.
I know some people have even talked about something to do with a multiverse, but of course that doesn’t disprove god either because logically with a being capable of creating one universe, why would he not be able to create more if it wished.
Answer by SmartLX:
The good old cosmological argument. This argument falls at the first hurdle, but drags on and knocks over all the others regardless.
– No, scientific evidence has not established that the universe began to exist. It has established that it was once concentrated at or near a single point, then expanded outwards. The evidence says nothing about whether the matter and energy in that point was created at that instant or it got there from somewhere else.
– There are two modern perspectives on matter and energy. According to the classical laws of conservation, they may be converted into each other but they are never created or destroyed. Since they exist now, this would imply that they have always existed and didn’t need a creator. On the other hand, according to quantum mechanics matter can emerge spontaneously in certain circumstances as long as the same amount of antimatter does too, because the total amount of positive energy stays the same. Again no creator is needed, so neither way supports the supposed necessity of a creator.
– If the Big Bang was caused by something outside of our universe’s space and time, it doesn’t make the cause timeless or spaceless. It might be a natural entity with its own spacetime and energy, say, another universe.
– We have never unambiguously observed a divine entity, so it is pure assertion to say it can exist outside of space and time. We have only observed the “abstract” (mathematics, logic, etc.) within the confines of a physical universe as it affects the objects in that universe, so we don’t know whether the abstract can exist without the material either. Regardless, you pose a false dilemma because there is at least a third choice: an object in a different system of spacetime. And the whole thing is moot until the necessity of a cause is established.
– No, the possibility of a multiverse doesn’t disprove the existence of a god, but nothing does. A god is a possibility in a multiverse as well as in a single universe. There’s just no good reason to think it’s real, let alone necessary.
