I think that they're both wrong.
The main problem I have with the big bang theory is that something came out of nothing, all at once, then all physical laws came into being that no one can break without being labelled a heretic. It simply makes no sense.
The other thing that I do not like about the big bang theory is that it views the universe as a strictly newtonian physical construct, where the only forms of matter are the ones that we know of (electromagnetic radiation, and the particles that we are aware of, that only interact in ways that we understand - irradiation, heating/cooling, colliding, fusing, fissioning etc)
I think that that sort of thinking is hugely arrogant, given that the entire electromagnetic spectrum is a tiny fraction of what is, and we have only been seriously studying this stuff for a couple hundred years out of the billions upon billions of years that the universe has probably been around.
The static universe theory has the same flaw, in that again, we have the continuous creation of matter to balance things out, so that you have old stars/galaxies being mixed with new stars/galaxies. Where did the new galaxies come from? Where is that energy come from? What is this, lots of mini big bangs happening all the time? So it's miracle after miracle, utterly annihilating the supposed laws of thermodynamics.
Then both of these clown troupes start talking about the background microwave radiation detected uniformly, and how its existence proves one and disproves the other.
If the steady state people are right, and there is a constant creation of matter, then the new matter would emit microwave radiation from those blobs of new matter, meaning that the background radiation would not be uniform. Fair enough, that makes sense, from a newtonian standpoint, because you don't get uniform radiation from multiple sources, and so steady state can't be true.
But this idea that the microwave radiation is "left over" from the big bang, and is bounced around by cosmic dust so that it is uniform when we measure it - what a load of crap. Anyone who has shone a torch through a dusty room knows that while light bounces around, it is definitely not uniform at every point in the room.
So the big bang people use the microwave radiation theory to disprove solid state, and by elimination, it means that the miracle of matter from nothing must therefore be true, even though it makes no sense at all.
Oh and by the way, amidst all this, we have multiple dimensions being proven to exist mathematically, and an abundance of "dark matter" that makes up most of the universe, even though we can't see it or interact with it properly at all.
What I think is going on is that there are processes of energy/matter transmutation happening around us that we don't understand, coming from directions that we cannot imagine (because the source might be in another dimension).
Further, I think that it is insulting that no one has said the obvious - that the microwave radiation is coming from space itself, because space is not the empty void we have been taught it is, and rather, a super dense, super fine fluid, the distortions in which actually make up all matter as part of a cymatic aetheric construct - which, by the way, Walter Russell was alluding to a hundred and something years ago when he said that the universe was harmonic in nature, was split into a physical and spiritual side, and then went on to accurately predict dozens of elements perfectly that had neither been imagined nor discovered.
The other thing that stinks is that we assume that the universe acts the way all matter does, newtonianly, when it expands and contracts ie when something expands, it cools down, and when it contracts, it heats up. Why? Why must this still be true in the magic universe where things magically appear with a bang? Doesn't it make sense that heat and cold may be regarded as relative, and that the rules of physics change as you move into different parts of the universe, where maybe matter can get bigger while not actually changing temperature or breaking apart?
The theory of gravity sucks as well. Einstein said that gravitational waves exist, and that gravity is a field that depends solely on mass. Yeah well when you get a bunch of atoms spinning in natural conjugated pairs and split them so that they are monoatomic, they suddenly become super conductors at room temperature. Then, when you heat them up, they change in mass. Then, if you keep heating them up, they disappear completely - they don't burn and float away, they don't conjugate with anything, they just flat out disappear.
So not only does the whole disappearing trick lob the second law of thermodynamics straight into the bin, since matter plus energy should equal more energy or more matter, but certainly not cancel both out, but the mass changes. Doesn't that therefore imply that gravity is not a wave, but rather, a relative interaction between matter according to phase, meaning that it is a gravitational effect, not a field?
You know what I think? Some dudes a long time ago like Einstein came up with a bullshit theory that everyone promptly wrote into textbooks, turning mere men into Science Gods.
Then everyone since has spent their career trying to look good by agreeing with Einsten and his Science Apostles so that they could score a grant and a professorship, while in the meantime, hardly anyone has had the balls to declare the bleeding obvious which is that Holy Einstein and all the professors who fawn after him, who have spent their lives and hundreds of billions of dollars chasing after imaginary particles postulated by the Science Pantheon, are completely full of superdense crap.
To make things worse, anyone with a jot of common sense, who says in even the quietest voice "hey fellas, how about we look at this from scratch with a fresh eye" is shouted down for being a heretic, by bearded old men with bleary eyes and too many letters after their names that they weren't born with, who shake their walking frames at them and threaten to burn down their houses and run over their dogs with the Model T they bought new.
Science died when Tesla did.
