The universe is an astronomical mystery, one that humans are still trying to understand. What would happen if you somehow managed to reach its edges?

At the edge, we see the leftover glow from the Big Bang — the so-called cosmic microwave background radiation (CMB). But this isn’t some magical edge of the universe. Our cosmos keeps going.

The edge of the Universe, as it appears to us, is unique to our perspective; we can see back 13.8 billion years in time in all directions, a situation that depends on the spacetime location of the ...

The edge of that is the place beyond which light hasn’t had time to reach us since the beginning of the universe.

With the help of modern telescopes, we literally can peer back in time to see how the universe looked shortly after some of the earliest galaxies formed.

The simulated large-scale structure of the Universe shows intricate patterns of clustering that never repeat. But from our perspective, we can only see a finite volume of the Universe. What lies ...

(via PBS Space Time) Have you ever asked “what is beyond the edge of the universe?” And have you ever been told that an infinite universe that has no edge? You were told wrong. In a sense.

The edge of the observable universe is about 270,000,000,000,000,000,000,000 miles away. If you drive at a steady 65 miles per hour, it will take you 480,000,000,000,000,000 — that’s 4.8 × ...

The visible edge of the universe is, by definition, the most distant thing that we can see. That does not mean it is the most distant thing we can feel, however. According to astrophysicist Alexander ...
