If I take a three dimensional thing, and stretch it such than one or even two of those dimensions approach zero, the measurements in the other dimensions get extremely large!

Pls don't give anyone ideas

If you take every grain of sand on Earth and stack them in a single column...

[–] VelvetStorm@lemmy.world 74 points 5 months ago (2 children)

And that distance is miniscule and insignificant.

"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.

[–] Allero@lemmy.today 13 points 5 months ago (1 children)

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.

[–] Classy@sh.itjust.works 4 points 5 months ago

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

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.

Like a prion

Folded for the very first time!

[–] Raverbunny@aussie.zone 8 points 5 months ago

I know it was Like a Surgeon, but I heard that comment in Weird Al voice.

[–] Rubanski@lemm.ee 7 points 5 months ago

Prions are so scary and so fascinating

[–] Leate_Wonceslace@lemmy.dbzer0.com 25 points 5 months ago (2 children)

I'd argue that a prion is folded badly.

[–] phdepressed@sh.itjust.works 12 points 5 months ago

Not from a free energy standpoint.

[–] ObsidianZed@lemmy.world 3 points 5 months ago (1 children)

Yeah, I was thinking more like a tangled knot of DNA. Which would be a good username.

[–] psud@aussie.zone 2 points 5 months ago

BadlyFoldedProtein (prion for short) would also be a good name

[–] Owl@hexbear.net 17 points 5 months ago

If you took all your DNA, straightened it out, and put it end-to-end, you would die.

[–] Etterra@lemmy.world 14 points 5 months ago (1 children)

Also you would die, but let's not think about that.

[–] onwardknave@lemmy.ml 5 points 5 months ago

One's neighbor's DNA would also work...

[–] Pulptastic@midwest.social 13 points 5 months ago (2 children)

All dna from one cell? Or all dna from all cells?

[–] No_Change_Just_Money@feddit.de 27 points 5 months ago* (last edited 5 months ago)

One cell contains 2 meters of follded dna 1

A human has 36 trillion cells 2

The distance between Earth and Jupiter varies from 588 million km to 999 million km and averages at 601 million kilometers 3

36 trillion * 2 meters / 0,6 trillion meters

120 times to Jupiter (or 60 times back an forth) on average

Or 72 times to Jupiter (36 times back and forth) at the highest distance

[–] flambonkscious@sh.itjust.works 7 points 5 months ago

Now look here... Is not meant to be actually thought about, just be impressed dammit!

Surely it's DNA from all cells??

[–] jballs@sh.itjust.works 6 points 5 months ago (1 children)

You're not small you're just really well folded

Basically a plot point for Three Body Problem

[–] psud@aussie.zone 2 points 5 months ago* (last edited 5 months ago) (1 children)

Spoiler tags don't seem to work in my client, so beware if you have only just started the books or tv series, or wish to not have your suspension of disbelief broken

That plot line is closely related to the biggest plot hole in the books and tv series

Sophons are sent to Earth at near light speed, presumably accelerated in a particle accelerator. They are the size of and very like protons. In fact they are protons that were unfolded, had AI computer logic etched into them, and were then refolded. How would they slow down? How would they change direction? Note that they are shown to turn within a fraction of the radius of a retina and hardly interact with matter at all.

A proton takes a fair bit of energy to accelerate to a high fraction of light speed, and just as much to stop or turn.

[–] jballs@sh.itjust.works 1 points 5 months ago

Oh yeah, they never explain the slowing down part huh? But they also seem to be self propelled somehow since they are zipping all over the place and slamming into particles inside of our particle accelerators.

[–] Aviandelight@mander.xyz 6 points 5 months ago

Had a good snort at that title. Well played.

[–] PlexSheep@infosec.pub 5 points 5 months ago

That's a stupid comparison, because earth and Jupiter change their distance all the time. Orbital mechanics and so on.

[–] secretlyaddictedtolinux@lemmy.world 4 points 5 months ago (1 children)

This can't be true! Really?

[–] LwL@lemmy.world 3 points 5 months ago

https://feddit.de/comment/10614517

Apparently it's closer to 100 times even.

You can fit a lot of very thin long thing into a small 3d space

Jesus gets sad when you get DNA in Uranus, or so they say

[–] Kolanaki@yiffit.net 3 points 5 months ago (1 children)

If I took all my DNA out of my body, wouldn't I be dead? 🤔

[–] Xtallll@lemmy.blahaj.zone 5 points 5 months ago

Not immediately, your cells could continue to function without the DNA in the nucleus, until they try to divide. Then you will turn into soup, it's basically what happens when someone is exposed to extreme radiation.

[–] bananabenana@lemmy.world 2 points 5 months ago

Everyone is always talking about spider silk as ropes. What about DNA huh? Mass strawberry extraction for a DNA space elevator when?
