From the beeb (BBC):

The Yepun Very Large Telescope complex in Chile has just found a galaxy more than 13 billion light years distant. That puts it very close to the beginning of the universe itself, which means we can learn a great deal about how our universe evolved from it.

Interesting article (well, to me), and note the size of the telescopes compared to the researchers in the pictures. Wow!:D

Hopefully the JWST, that has longer wavelength coverage than the Hubble, will observe galaxies that are even more primordial! Perhaps it will spot one that is older than 14 billion and, therefore, older than the “universe”!

Heh, let's hope not! Either we don't know how to measure the Hubble parameter, or much of what we know about cosmology will turn out to be wrong.

Well, my perspective is perhaps more consistent with your latter statement - that much of what is currently known about cosmology is wrong!

after reading so much about astronomy and quantum physics, my view is also the same. our understanding of gravity may even be flawed.

Yes, standing on the shoulder of giants does not help one to see beyond a horizon! For me, incremental "corporeal" knowledge in Vyavaharika may be defined in terms of the unravelling of a single variable. However, it is still only one variable in the huge partial equilibrium model that represents human empirical reality. The fact that this partial equilibrium has apparent inherent and internal consistency is itself a falsity because it is a derivative of the limited sensory perception imposed by evolutionary biology.

It would appear that Professor Penrose supports the view that there are "pre-Big Bang" events and possibly even concurs with the notion that the Big Bang is cyclical:
