"If you took all the DNA out of a person and laid it end to end, that person would die."

The distance to Jupiter from Earth is but a mere blip though. Even the galaxy is small compared to what's beyond.

Thanks to chaos theory, what we do here can have some effect on the far future of the Universe, at least, for those places within causal reach. How meaningful that effect can be remains to be seen.

But do bear in mind that even, say, a cow farting in a field in France last Tuesday might have as much effect as everything you ever do.

Has anyone ever done a quick calculation about the above with the population?

8 billion people x distance to Jupiter = Anywhere close to Proxima Centauri?

I'll be not lazy when I'm done shitting then someone can come in and correct my math after if ai even remember to do it by the time I get back to my PC.

E: 714 million km distance to jupiter. 40,208,000,000,000 km to Proxima Centauri.

40,208,000,000,000 / 714,000,000 = 56313.72549019608

714,000,000*100 = 71,400,000,000 km end to end for dna is more likely per reddit.

Alternate non nasa distance to proxima centauri is 39,900,000,000,000

39,900,000,000,000 / 71,400,000,000 = 558.8235294117647 people's dna end to end to reach proxima Centauri.

How about light years? A light-year is 9.44 trillion km or 9,440,000,000,000 so 132.2128851540616 people's DNA to go 1 light year.

8,000,000,000 / 132.2128851540616 = 60,508,474.5762712 light years of travel distance using the entire population of earth.

Milky way is 100,000 light years across.

So end to end every current human's DNA would stretch across the Milky Way 605.084745762712 times.

Andromeda Galaxy is 2.5 million light years away.

60,508,474.5762712 / 2,500,000 = 24.20338983050848 times to Andromeda Galaxy and back.

We have galaxies even closer to us so really it's just a hop and a skip away...

944,000,000,000,000,000 km.

I'd start with the notion that the distance from Jupiter to Earth is very much not a constant value, and can be many times different depending on both planets' positions around the Sun.

1 + 1 = 2, or sometimes it's 6, you know things can move sometimes
