The world needs clear thinkers, and I know a clear thinker when I see (read) one.
The big bang does not make any sense and I still wonder why scientists can ignore the clear notion that if there is 'nothing', not even space and time, there is no mechanism that can describe mathematically how space and time suddenly exist along with all the energy and particles this universe is made of. And how come all gazillion fundamental particles thast were 'created' in the Big Bang at once have the EXACT same properties? Why is every proton, every electron exactly the same?
The big bang had so many fixes it's embarassing. Why is the universe so homogeneous? Big bang can't explain this. No, wait, we'll introduce Inflation.... after the big bang!
And what do we know? How is the crisis in cosmology solved? We can't even explain things we observe today and need dark matter and dark energy to come up with theories. Let alone explain the universe as a whole!
My personal guess is that the universe is and has always been in constant creation. particles pop up in empty space and are the energy that eventually creates all the particles we know in the exact same process that has always been and always will be. Perhaps there is expansion but the question were it expands into is meaningless, it is not expansion in the way we can picture in our minds because space and time are in constant flux. Just as our intuition breaks down at the quantum scale, it breaks down at the cosmological scale. It is like expanding into itself I guess. But don't try to picture this.
By assuming the (or a) beginning of the universe, we need a cause. What caused it? As long as there is not even a single clue about it's cause, the asssumption should be dismissed.
If the most precise measurements and data show us that we only see mature galaxies as far as we can peek into the universe we can safely say the assumption is falsified.
We should not feel like we can one day 'understand' the universe, just because we've come so far tin the last century. After all we're still just dumb animals, destroying our own habitat. We're way too limited to be able to ever grasp this.
About the CMB, we measure background radiation in all directions, we assume this is the remnant of the big bang but no other causes or sources have been proposed (like vacuum energy), it was 'proof of the big bang' from the beginning. But if the big bang was here and everywhere, this 'background radiation' is all around us and fills this entire space. How can we 'see through it' ? How can a depiction as a flat map (as we know it) ever be correct?
Is the CMB perhaps just proof of the process of continuous creation of energy all around us, in every direction in the same amount, everywhere there is a vacuum? We'll simply never know for certain because we can't measure it and probably will never find the right mathematical model for it, before our world is destroyed by ourselves.
