Question:
Does the sun decrease in size as it is burning. If so, does the size difference relate to the estimated three and a half billion year it is claimed to be?

Replies:
The Sun is actually increasing in size and will become a red giant before shrinking to a white dwarf in many many eons time.

The Sun at the moment pulsates in size, once every 5 minutes or so, by about 200 km in diameter.

Although there is some debate over the age of the Sun, the general consensus is that it is ABOUT 5 thousand million years old.
