All that meaningfulness means nothing WHEN the certain scale of space and time is ended.<quoted text>
... A life has meaning at a certain scale of space and time...
Your life is meaninglessly meaningful. I get it.
By the way, in light of scientific fact that you provided, all that meaning you speak of is pure philosophy and "pipe dreaming".
Science proves/supports my claim that your existence is meaningless, eventually futile.
Science itself agrees with me that your existence is meaningless.
