Some of that zooming in made me feel pretty damn uncomfortable. It really is f'ing massive out there huh. Makes me wonder what this is all about, I'm sure it's something, I wonder what. :)

The actual problem is that we were made early enough to begin to understand the full scale of it, but we're still not mature enough to go out there and explore it. Therefore, you can reason that now is the right time to get behind anything that pushes us beyond the Earth.

These distances are well outside the scope of exploration. Getting to the next solar system is already a seemingly insurmountable challenge. Getting to the next galaxy? Forget it. Getting to these galaxies we see in the picture? Absolutely no way. I know people like to be optimistic about these things but it's honestly pure wishful thinking.

Once we have fusion reactors, it won't be.

It’s even more “massive” down below. There are only 27 orders of magnitude between human size and the size of the observable universe, but 35 orders of magnitude between human size and the Planck length. ;)

It could really be much larger beyond the observable horizon though? But I guess we will never know.

Unless faster-than-light travel becomes possible.

Your fusion reactor will still take a while to travel 420 million light-years.

This is short-sighted. Maybe not in our lifetimes. If it were 1902, you'd probably be mocking the Wright brothers.

And a currently unknown number of OOMs (possibly infinite) beyond the observable horizon.

Fusion reactors won't really help. Sure, you can accelerate indefinitely - but only at maybe 1G or a bit more if you don't want to kill the occupants. Then you have to flip and decelerate. Unless we find a way to freeze/stasis people, the limits are still shockingly small.

We'd need to start cracking some kind of jumping/FTL/etc technology to have any hope of real exploration.

How arrogant and silly to look at these incredible pictures and think “Yep, this was all made for ME. I am the center of the universe!”.

How arrogant for anyone to look at these incredible pictures and think they know ANYTHING at all. We may be the center of it all, we may not, this may be a massive simulation, or a massive random accident. The only correct answer is to admit we know nothing. Humans are so fixated on knowing everything.

I think this line of reasoning does a disservice to all the scientists and thinkers who contributed to a considerable amount of knowledge. We learned so much about the universe in the past 100 years, it's impudent to call this nothing just because it's not everything.

No, I wouldn't be. The speed of light is a much more fundamental limitation than anything we have ever seen before. It's probably the single most fundamental and most sure fact that we know of, besides perhaps the quantum nature of reality.

And I have heard it all before: worm holes, warp drive, etc pp. A fun exercise, but not rooted in reality at all.

All you can do is to appeal to completely unknown, unimaginable magical breakthroughs, which are inherently difficult to discuss, so I don't think this will be very fruitful.
