Interesting. I'm no expert on this stuff, but as I said, I recently read Hawking's "A Brief History of Time". As I understand what I read there, there is no "edge" to the universe, but I thought the curvature just meant that if you could travel faster than light in one direction, you'd eventually end up back where you started. Also, if you were traveling faster than light, then you'd be traveling 4 dimensions, not just 3, so you could arrive back where you started before you actually left.
But I didn't realize that there would be more out there than we're capable of observing due to light speed limitations.
thats right.
They don't know yet. They are still looking. They aint even sure that those galaxies so far away aint our own milky way 10 billion years ago.
remember they know less than 10% of the stuff out there. Everything we know is a human perceptive only.
