What is beyond the farthest galaxy?

Many stories are told that people think exist in our universe.

I've heard that there are millions of galaxies outside our solar system; perhaps there is another Earth-like planet out there.

It would take 100,000 years to cross the Milky Way at the speed of light, but that speed is impossible to achieve. We know that it takes roughly two years to get from one place in the Milky Way to another, and that it takes 9.5 years to get from one place to Pluto. Nevertheless, we will never know unless someone goes out and returns and tells us.

In general, no one has ever been able to see past the furthest galaxy, much less travel there.

The observable universe is estimated to be about 93 billion light-years in diameter, but it is unknown what lies beyond that limit. Some theories suggest the possibility of a multiverse or other dimensions, but these ideas remain speculative and have not yet been confirmed by empirical evidence. Beyond the farthest galaxy, there is likely more of the universe containing additional galaxies, clusters of galaxies, and vast regions of empty space.
