What are the dimensions of the universe and what would be the total area, mass and/or radius, etc of the whole universe combined?

Answer 1

We don’t know yet.

The "observable universe" continues to expand as our instruments improve, with numbers fluctuating nearly annually. This is particularly problematic when attempting to calculate mass. For more information about the uncertainties and future research, visit https://tutor.hix.ai

The size of the universe is not precisely known. Observable universe radius is approximately 46.5 billion light-years. Total mass and area are challenging to quantify accurately due to uncertainties in dark matter and dark energy.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
