Things That Will Never Exist in the Universe

As much as we daydream about zipping through galaxies, reality is throwing a cosmic curveball. Interstellar travel is like the unicorn of sci-fi dreams – we want it, we wish for it, but it's as elusive as a disappearing asteroid. First off, let's talk distance: it's about light-years of distance. Our snazzy spacecraft might need thousands of years just to reach the nearest star. Space is vast, sure, but it's also packed with cosmic obstacles like asteroids, black holes. Sending messages, let alone physical stuff, across these distances is like sending a snail-mail letter to a galaxy next door. So, while we'd love to pack our bags and zoom off to explore the cosmic unknown, for now, interstellar travel remains in the realm of sci-fi books and futuristic daydreams.
