How can hydrogen and helium have 'always existed' according to some theories, where the heck did it come from orginially?

I saw it i this documentary 'planets in our solar system' Believing that the universe has always existed is called steady state theory right?

What is a Theory anyway It appears that when the first Atoms formed, The Universe had cooled down enough for the loose particles to condense from the cosmic Soup It was estimated 3 Microseconds into existance The Fabled Higgs Boson was the first to form Notice I didn't say whole atoms? The Higgs Boson is what Bonds Atoms together and give them mass Hydrogen and Helium as well as Deuterium were the first to form They have the least particles, and have the Least Mass and were quick to form the first Stars


We know where hydrogen and helium come from --- they come from the process of "Big Bang Nucleosynthesis". I refer you to Steven Weinberg's book, "The First Three Minutes", which explains this and explains how we know it.


That is the steady state UNIVERSE theory, NOT the steady state theory. That is an entirely different hypothesis, not a scientific theory. Didn't I already answer this question? The steady state UNIVERSE theory has been debunked. WHERE are the WHITE holes? Quasars don't qualify. If you are going to insist on wasting our valuable time playing sarcastic semantic word games, don't be surprised when people start reporting versions of this rant as spam.

You'll need to ask a proponent of the steady state theory and ask them. Good luck.


thay havent always "existed" hydrogen came from the energy that did exist


The Steady State Theory was certainly a popular one at one time, with one of its major proponents being Sir Fred Hoyle. There is no reason why "everything has always existed" couldn't be true. It is merely an assumption that "there must have been a beginning". It's perfectly plausible to suppose that the universe could have existed just as it is for an infinite time, with stars being born, dying and the matter being recycled, especially with the state of physics and astronomy being as it was over a century ago. So it was a perfectly respectable theory. It was only when Hubble discovered the universe is expanding that the cracks started to show. If that is true, surely the spaces between galaxies should be infinitely big by now? Hoyle and others had an answer - matter is spontaneously created all the time to fill the gaps. Which is conceivable according to quantum theory. But it's starting to sound more incredible (in the proper sense of the word, meaning "not believable"). What really put the kibosh on Steady State (except if your name is Fred Hoyle) was the discovery around 50 years ago of the cosmic microwave background. The theory has no explanation for this. It was in fact Hoyle who coined the name "Big Bang" in a radio talk as an easy way to describe it, He is also responsible for the first scientific papers on how elements are made by nuclear fusion in stars. He was a good astrophysicist. He just had a total blind spot about the Big Bang (and in relation to his other big controversial idea, that life on Earth came from space - which of course begs the question "how did THAT life start?")


That theory is nearly 100 years out of date

The universe expands and will eventually collapses according to scientists.


Both were created in the first few minutes after the Big Bang (along with some deuterium and lithium).

The steady state hypothesis does not fit in with our observation of a temporary universe. It could be cyclic, but it is certainly not steady. Most of the errors in theoretical cosmology are caused by the belief that time is somehow separate from the universe. That is largely a problem with the English language as Quentin's answer shows. Time is a dimension of the universe and elapses as the universe expands. If the universe should cease to expand, time will cease. There is no "after" that and no "before" big bang. If the universe is cyclic, every quarter cycle is identical and represents the universe expanding as time elapses and the universe ceasing to expand at the end of time. The reverse quarter cycle and the inverted half-cycle are concepts that only mathematicians can understand.


In the future the universe will get very large then start to collapse in on itself. This will create a black hole. The black hole will go through a wormhole caused by the space time dilation around the black hole and go back in time to the big bang. The big bang will bang again.
