@xinsideus: Background: A human has approximately 6 trillion cells that contain a nucleus and thus DNA. Each cell nucleus holds about 2 meters of genetic material, which adds up to a total length of 12 billion kilometers for the DNA of a single person. Now, if you multiply that by the Earth's population, you get 96 trillion kilometers. Light travels roughly 300,000 kilometers in one second. In a year, it covers nearly 9.5 trillion kilometers. Alpha Centauri is 4.34 light-years away, which is over 41 trillion kilometers. The DNA of humanity could span that distance over 2 million times. Going further: The Milky Way has a diameter of 105,000 light-years, which is almost exactly 1 quintillion kilometers. Accordingly, the DNA of humanity could cross that distance more than 96 times.
