"Probably just the vastness of space, the unfathomable distances between everything, and how comparatively slow the speed of light (and other massless particles) is.
Unless we manage FTL travel, which seems unrealistic because it would seemingly open up a bunch of nasty paradoxes, we’ll probably never leave our solar system, let alone leave our galaxy.
The Observable Universe is like a strip club; we can look as much as we want, but we can’t touch any of it."

#11 If that representation is accurate, it does not look very fast, as I would imagined.

Emmy, 240,000 miles in less than two seconds? That seems pretty fast to me.

#15 CMEs destroy electronics. They don't do anything to living things, with the small exception of possibly peeling away the earth's magnetic field long enough to give everybody a sunburn.

Leonidas,
A Coronal Mass Ejection the size of the Carrington Event would completely destroy the electrical grid. It could take as long as ten years to replace damaged power transformers and restore electric service. Big cities can't survive ten days without electricity.
Sit back and enjoy the show, because there's not a darn thing you can do about it.

Nana,
That is the biggest and best example of how society at large is ignoring a very real and very imminent threat while spazzing out about all sorts of less important things. For chrissakes, our electrical grids getting wrecked by a giant sun-fart is certain to happen eventually and practically nobody even knows about it!

The so called universe is a great example of infinity. There is no end. Big bang theory is continuously proven unlikely. We have fairly well proven that time is related to velocity. So there can be no beginning and no end. Because somewhere there is something going so slow that it would have not experienced any time. We really need text books to catch up. Right now people are seriously mis-guided by our cr#ppy for profit education systems.

#17 1420Hz is the sound of Hydrogen, in 2017 - after research - it was concluded with great certainty that the signal came from a then undiscovered comet!
