To observe the expansion of the Universe astronomers used the standard candle of a certain type of Supernova. By seeing how bright it was they could calculate how far away it was. There is a problem,  however. As you look further away into the universe you are also looking back in time. If the universe was once a point that expanded it would be a smaller universe the further back you looked. However looking at something 2 billion light years away looks like it is on a sphere 2 billion light years in radius and looking back 4 billion years a sphere of 4 billion years in radius.

The further back you look the bigger the Universe seems when it is actually getting smaller the further back you look!

This not only magnifies objects the further back you look but makes them dimmer as well...giving the illusion they are further away than they are! Your standard candles become dimmer over time as a result making the universe look like it is expanding at a growing rate the further back you look!.

All this conjecture  about an accelerating expansion is built on a faulty foundation!

It’s probably not expanding uniformly in all directions. Gravity is different in different concentrations of mass, and mass is certainly not evenly distributed in the Universe.

I would think that the Universe is not a sphere but a lopsided blob that is expanding at different speeds in different directions..............

Logic fail.
