No sir! You have not made any measurements 10,000 years ago, never
mind billions of years.
Your calculations are all based on extrapolation of recent calculations, using definitions that are ASSUMPTIONS.
Now, these assumptions might be right .. but we do not know that.
Without basic definitions of time/space/energy etc. , we cannot make any calculations.
We make these definitions out of necessity .. they are assumptions.
Of course, most people don't realise that .. they see science as an exact 'thing', rather than what it is..
..a tool.
