The duo sat beneath what might be called a tree. It was not a tree, nor were the duo human.
The ancestors of the duo were certainly human, but humans had officially been extinct for tens of trillions of years. The tree that was not a tree had a similar relationship with trees.
Life still existed, and it still lived on planets. Society still popped up here and there, meaning the life forms never ceased needing to use communication.
“Can you see it?” The larger of the pair asked. It was not English, or even a verbalized question, but it was a question asked and interpreted in a way we would not understand.
The smaller one focused its light-gathering sensory organ on the tiny, nearly imperceptible speck of light. “It's so small and faint. Did it recently used to shine brighter than that?”
“Not only did Proxima Zeta once shine much brighter, but it was also one of over a dozen stars!” The larger one exclaimed.
“Some historians say that there may even have been a hundred stars visible in the night sky.”
The smaller one was silent. “Is that even possible?” It was hard to comprehend that many stars.
“It's certainly fun to imagine, isn't it?”
The smaller one agreed.
“Anyway, we are sitting out here and watching Proxima Zeta, because soon it will be gone.”
“What do you mean? Where's it going?”
“Well it's hard to explain.
It will still be there, but because the universe is expanding at a rate faster than the speed of light, within a few days or weeks,
the expansion of the universe between us and Proxima Zeta will exceed the speed of light. When that happens, we will be alone.”
The smaller one drew in toward the larger counterpart. “I don't want to be alone.”
The larger one was often accustomed to telling comforting lies to the smaller, but perhaps it was time to start a habit of honesty. “I don't either.
” The voice, or however it was these denizens of the universe communicate trillions of years hence, was tinged with a deep sorrow.
Yes, it was sad, but the universe was a cold place, and with each passing moment grew ever colder.
