What scientific fact blows your mind the most?

Life is a process of things interacting consistently with each other.
Why would a static screenshot of exact chemical composition matter for any process that involves a moving or animated body?
A bricked computer with a corrupt boot loader is chemically the same as one that actually works.
A car is chemically the same before and after you turn the key on its ignition.
A lightbulb is comprised of the same substances whether or not its turned on or off.
... Part of the difference between an alive and a dead body, is that the chemical reactions that constitute animating the thing into being alive ... have stopped.
A dead body is not metabolizing. It has no brain activity. The chemical reactions required to keep its heart beating are no longer happening.
Decomposition then sets in.
These are all differences in chemical processes.

How do we stop radar? By obliterating the air around us with cube. Lol
That is actually pretty neat though!

Recent studies have it at closer to 92% 'junk' DNA, and 8% actively coding.
Also, a lot of non-coding DNA does actually serve other useful functions, it just doesn't actively code.
It could play a role in epigenetics, ie the regulation of what active coding sequences are active and when, it could be telomeres that prevent DNA strands from unravelling at the ends, it could be binding and scaffold sites that assist in the structural stability and integrity of the chromosome.
DNA can be functional, without being active-coding.
Only regions that are both non coding and also totally non functional are truly 'junk', but we keep consistently finding more ways that 'non functional' regions are actually functional.

The problem is that they will tell people to pray away cancer, that diseases and injuries and such can be healed spiritually.
That means you can end up with kids who need actual medical help, and won't get it, and will then be told that they're sick because they didn't pray hard enough, that their soul is impure and that's why they're sick.

So humans vision is much more sensitive to green than other colors. it's why camera sensors are 50% green 25% red 25% blue. Which makes sense as being able to detect small differences in plant cover is useful in both detecting predators and prey.

If humans had more flat color detection range we woulda actually be able to see that the sky is purple and not blue.

My old school had a scale model of the solar system. It used the same scale for the planets size and distance. The sun was a 12" ball on one end of campus. Around campus were poles with little glass domes on top inside were tiny pins with little planet models on them.

Because this is a science thread I'll be a bit pedantic. Mostly because I think it's an interesting topic. It's a mass-energy equivalence (≡) and not just an equality (=) they are the same thing.
So it's meaningless to say convert mass into energy. It's like saying I want to convert this stick from being 12 inches long to being 1 foot long.
You can convert matter (the solid form of energy) into other types of energy that are not solid. But the mass stays the same.
It's like when people say a photon is massless. It has energy and therefor mass. It just has no rest mass. So from the photos frame of reference no mass but from every other fame of reference there is mass.

I'm terrified of going into lakes and rivers because of what might find its way into my skin.

thanks! love me some science pedantry.

Engineers never really claimed that. Motivational speakers did.
Scientists admitted that their models don't show how bumblebees can generate enough lift to fly. By now, they've improved their models, taking into account that at an insect's scale, air behaves much more like water. It "appears" to be thicker because the air molecules are larger in relation to an insect than to a human. -
Exactly! If it was just magic, things seem underwhelming all of a sudden - like why couldn't you give zebras wings or laser vision? Why not have a grizzly bear with chainsaw arms on wheels? Makes nature seem arbitrarily limited and uncreative in comparison to what unlimited magic could accomplish.
(Just to be clear, this is not an argument against God btw, you could always just say "god did evolution and has reasons for not going all out with creativity)

alien planets could be purple
So the prophecies are true...
