I wish we could have faster than light travel by compressing space somehow, go to these 50 billion light years away objects and actually verify if they are a galaxy or not. Even if you could insta teleport to every object, I think it would still take an infinite amount of time to visit every star, every galaxy and every planet for just 10 seconds
I predict that if faster than light travel is possible, we will have it within our lifetimes, perhaps even as soon as 20 years ago.
You can't get there because you can't out run the growth of space itself and even if you got there, whatever it was you came to see was there at last 50 billion years ago and wouldn't look the same, or possibly no longer exist.
Not 50 billion years ago because the universe is only about 13.8 billion years old as of current thinking. Space has been expanding in the time it's taken light to travel so "light years away = time ago light was emitted" gets increasingly wrong at longer distances
