    We're underselling the skill it takes to write that small at an awkward angle.

    Space is sooo big that if you chose one direction and travel in that way billions billions years faster than light speed you will end at same place where you start.

    We can't tell, really. Like a ship in the empty ocean, astronomers on Earth can turn their telescopes to peer 13.8 billion light-years in every direction, which puts Earth inside of an observable sphere with a radius of 13.8 billion light-years. The word "observable" is key; the sphere limits what scientists can see but not what is there.

    But though the sphere appears almost 28 billion light-years in diameter, it is far larger. Scientists know that the universe is expanding. Thus, while scientists might see a spot that lay 13.8 billion light-years from Earth at the time of the Big Bang, the universe has continued to expand over its lifetime. Today, that same spot is 46 billion light-years away, making the diameter of the observable universe a sphere around 92 billion light-years.

    Space may not be infinitely big, but it's so big that you would never know the difference. It's so big that anything that could logically exist must exist somewhere.

    It's my opinion that since no one really knows what space is exactly, that there's no way anyone can accurately gauge how big it is. For all anyone knows, this might only be one universe in a multitude of universes. I highly doubt the question will be answered in our lifetimes, if ever.
    No drug, not even alcohol, causes the fundamental ills of society. If we're looking for the source of our troubles, we shouldn't test people for drugs, we should test them for stupidity, ignorance, greed and love of power. — P.J. O'Rourke

    Sin lies only in hurting others unnecessarily. All other "sins" are invented nonsense. — Robert A. Heinlein (1907-1988)

    Then again a hill of beans probably looks big to an ant,Einsteins.
