I've been thinking this over for a few weeks now. If the universe is always expanding, what is it expanding into? And if the fabric of spacetime can be ripped, what happens when matter and light escape it into that void? It there another universe? Nothingness? Or is there something else we possible could never understand?
Humanity can never answer this question, with our technology it will be hundreds of years before we can correct space travel, but where will we get fuel from etc when going around space?
We have only been on Earth for around 200,000 years, so, it is still early days if you look back at such animals as dinosaurs when they were millions of years old, and rising CO2 levels, i don't think we will even survive the next 2,000 years, and we haven't mastered space travel, and no planet in our solar system is suitable for Human life.
Space travel just to get outside our galaxy which we are located would take millions of years, and keep in mind we are not even a quarter of a million years old!
