Sam and Alex are about to witness the end of all things.
"Well, here we are." Sam said.
"At long last," Alex replied.
"Long? Only eternity."
Of course they couldn't be where they were and doing what they were if they had bodies and such things. What they are boils down to being the last two individual consciousnesses in the universe.
"What do you think it will look like?" Alex asked.
"I don't know. It will probably be hard to tell, what with space and time and us collapsing into it," Sam answered.
"Yeah... the Big Crunch, as it were. We probably should have stayed longer at the Big Bang."
"Gone back further you mean?"
"I suppose we did see the good part," Alex suggested, essentially with a smile. "Everything was sparkling and new."
"So full of energy, it was. Bursting forth to begin an eternity of creation and existence," Sam added.
"That was so long ago..."
Alex became a bit slower, having to really stop and think for the first time in a long time. "What were we doing before that?"
Sam hardly hesitated at all. "We were on our way there."
"But before that? What did we spend our time doing?"
"We don't spend time anymore. We're soaking in it!"
"Your muddling things up again," Alex said, essentially with a pout. "You always do that... to distract me."
"Distract you from what? The smoldering stars racing towards oblivion? We can always go back and watch it again."
"How can you say that? How can it be certain? The universe is ending!"
"Well there won't be anything left after that?"
"But there's an eternity of infinity before it."
"But will we exist after it?"
"We existed after the beginning... for an eternity." Sam wondered, "Don't you remember?"
"Of course I do," Alex resolved. "But we're at the end. What happens after?"
"Well quite definitively nothing, I would have to say."
"Why do you say that?" Alex asked, as the last bits of time and matter were now but an infinitesimal distance from that singular point of annihilation.
"Because," Sam replied, gazing on in wonder. "Everything happened before."
