if time is slowing down then doesnt that mean that it use too go faster and if it did go faster then how fast did it go when the universe started and also if it did go faster back then, then the time we estimated how old the universe is not as old as we think it is.... so in fact it would be a lot younger then what we think of it now????

if time really slowing down doesnt that mean that it was going a lot faster in the past before so wouldnt the universe be alot younger then we think it is????
