If $1 / H_0 $ is about 14 billion years, then what happened when the universe was half its current age?
Is the empirically determined $H_0$ supposed to have been twice its current value?
And when the universe is twice its current age is Hubble's parameter half its current value?
That would predict expansion is slowing. But expansion is actually speeding up. That implies that $ H_0 $ is getting larger, and because $1 / H_0 $ gets smaller in that case, the universe is growing younger.
I asked this question already here, but it was marked a duplicate. I know that Hubble's Parameter is not a constant. That doesn't actually clarify the answers to these questions.
