Even if we could travel at speed of light, the fact that we could do so for a year and not be very far into the universe is staggering.
Not so smart are we. Man can't travel at the speed of light and we really would need to go faster to get anywhere, yet we can't look after the island that we live on.
Yeah that always makes me feel really small.
Our tiny little lives are but a grain of sand on the beach of the cosmos.

Oh, I don't know. I once put on a pair of lined running shorts that had a wasp in them. I think I got those off quicker than that....

Yeah I still struggle to understand how they can say this happened so many billion years back, when, well, billions of years...yeah yeah, science, but still...guess its easier whan you have such a big window 2.229 billion years, margin of error of 5 million...pfft.
@booboo also time, in terms of light years, some more staggering numbers
A light-year is a measurement of distance and not time (as the name might suggest). A light-year is the distance a beam of light travels in a single Earth year, or 6 trillion miles (9.7 trillion kilometers).
Yeah that always makes me feel really small.
The fact the that farthest star is reachable (if still around) if we travel at the speed of light for 9,000,000,000 years.
Even if we could travel at speed of light, the fact that we could do so for a year and not be very far into the universe is staggering.
What I found most interesting is given the expansion of the universe, we're currently living in an era where it's observable and provable. If the human race lives long enough, our ancestors will have to take our word for it, because they won't be able to observe it.

Think of it as the interior of an expanding balloon. And I acknowledge the obvious other part of the analogy.

the obvious part is what gets me. As teh balloon expands, it takes up more of the room i am in. What room is the universe in?

Crazy shit. So when there was just a singularity at the start, what was outside it? Nothing, not like space nothing, but nothing at all. Not time, nothing. Impossible to imagine. Then you start talking about quantum computers, tied particles, teleportation, etc etc.

@Machpants how can there be nothing? and then something?

And at the other end of things ... what was there BEFORE the Big Bang?
Apparently there wasn't even a "before" before...

I can't compute it, I just accept it. In the same way I accept quantum physics

Go outside. It's going to fill the world up eventually, but that size is hard for our brains to process as well I guess.

No idea, I was only working on the balloon inside example and I can't imagine a balloon filling up the whole world but can imagine it expanding off into the distance. (I didn't explain myself properly on the first reply and likely haven't done any better now).
I'm in the it is what it is camp - otherwise it's sky fairy time ....
-
@Nepia but if it expands off into the distance, what was 'in the distance' in the first place...surely just more 'space' for the balloon to expand into.
What is a light-year?
