Check me on this distance thing:
The oldest stars in the universe are some 14 Billion Light years away. That’s 186,000 miles per second, times however many seconds there are in a year, times 14,000,000,000.
And yet, some scientests calculate the nearest parallel universe is only 1/10,000,000,000,000 of a millimeter away from every point in space.
So, which one seems further away to you? Odds are you stand a better chance of reaching the oldest star than coming in contact with a parallel universe.
