Cosmic Portals Poem by Je'free Y .

I do not think that physicists discussing
The plausibility of time travel will be surprised,
If one day, their descendants knock on their door;

Then, the Grandparent Paradox will step in -
If they eliminate their grandparents,
Will they eliminate their own existence?

If a black hole, a tunnel of time, is a product of collapse
Of a massive star with extreme gravitational force,
Then probably a wormhole to a parallel universe exists.

What was once hypothetical or science fiction will prove
Einstein's theory of time & space, or theory of relativity,
Validating the geometries of space-time.

Jumping into infinite timelines, exceeding speed of light,
Maybe, leaving and returning to the earth and only aging
Slightly compared to our peers becomes possible.

If we try to change history to change the present,
Will the mind revert to its past state?
For now, this is like answering zero times infinity.

Are we controlled by fate, or do we have the ability
To change what has already happened in the future?
Are we able to create instant prophets?

Well, I guess, we still travel to the past via memory,
And travel to the future via imagination, into a future
According to decisions in the past and the present.
