What scientific fact blows your mind the most?
-
Gravitational time dilation is an effect of Einstein's General Theory of Relativity. Places with stronger gravity would then have time pass more slowly compared to earth. The opposite is also true.
-
The label 'homo sapiens' for our species.
-
(I'm going to abrasively emphasize the conjunctions more, because I feel they're being glossed over)
IF the truths of our universe are completely mathematically and axiomatically bound, then any proof derived within it might have a chance of upsetting a given axiom given the either incomplete or inconsistent nature of mathematics as declared by Gödel.
I'm NOT saying the universe IS mathematically bound. I actually believe that maths merely describes our reality at varying scales.

that's still waaayyyy more efficient than coal
-
yes, the same atoms are still there, but all the chemical processes in our body have stopped.
-
To be fair, a perfectly fine but dead body is impossible to observe since the process of dying is usually the result or accumulation of injuries or disfunctions. For this experiment you either have to kill somebody without altering their body in the slightest or instantly conjure a perfectly intact body without any life in it.
-
That is a different level entirely.
The mass-energy conversion from chemical processes is extremely small compared to nuclear processes, you can't really compare the in any meaningful way

Retinal photosynthesis, also known as the Purple Earth Theory. Colours are weird. Earth plants absorb red and blue light, they look green to us because that’s the wavelength of light that cannot be used by the chloroplasts.
It’s hypothesized that this was advantageous on Earth because blue light goes further into water than the other wavelengths, facilitating the development of photosynthetic algae
Retinal photosynthesis is another viable chemical chain reaction that could be used to create ATP (usable biological energy) from light.
It’s another molecule similar to chlorophyll, but it absorbs green light instead of red/blue - alien planets might be purple!
There’s a viable parallel evolutionary pathway that leads to plants with magenta leaves

Correspondence of lovers:
He: darling, without you 60 minutes seem like one hour to me!
She: I love you so much, wow he is such a romantic! -
It’s so absurdly big. Our galaxy (the Milky Way) is estimated to have between 100 and 400 billion stars in it. For a long time we thought our galaxy was all there was, it wasn’t until 1925 when Edwin Hubble was able to prove that M31 was not a nebula or cluster of stars in our galaxy, but in fact an entirely different galaxy altogether that we realized there are more galaxies out there.
Look at the
image. This was a taken by pointing the Hubble Space Telescope at a basically empty bit of space 2.4 by 2.4 arcminutes in size (for comparison, the moon has an apparent size of about 30 arcminutes, or half a degree). So an absolutely tiny part of the sky. It contains about 10.000 galaxies.The observable universe is estimated to have between 200 billion and 2 trillion galaxies in it, with on average about 100 billion stars per galaxy. It’s absolutely mind blowing.

I think it's the Mormon bit that's being questioned.

Now, think about the energy and forces involved when 2 supermassive black holes orbit each other and collide.
-
Kolob is a planet or star where God resides. Time moves very slowly there. Hence the high gravitational field. Probably because God is massive. I don't know. I'm not a Christian scientist.
-
Ooh, those aspects are well beyond my capacity for comprehension or visualisation! I feel like an ant watching nuclear explosions.
-
yes you can. coal costs ~32 cent per kWh, and uranium ~$0.0015 per kWh
-
If mass can convert into energy that easily then we’re all in a lot of trouble…

I dunno whether it counts: but that science has effectively cured AIDS.
In 2004, 2.1m people died from it. Twenty years later that figure was a little over a quarter at 630k. The goal for 2025 is 250k. I think that's absolutely remarkable.
As a child in the 80s I was terrified of AIDS. It made me low-key scared of gay men because the news made it sound like I could I could get it from any one of them. And here we now are, able to provide a medication that can almost completely ensure that you will never be infected by HIV.
Astonishing, really.

We were talking about the mass-energy conversion, for nuclear fusion.
Not really sure how nuclear fission Vs coal cost/kWh is relevant.

I mean, you're not wrong.. XD
