Diamond is not the hardest material on Earth, tho. Mostly because humanity looked at that and said "I can do better, God", and then we went and did. Yeah, it's hard as balls to actually do something with the carbon microtube thingies, but they're deffo harder to break than diamonds.
himitsu keisatsu seifu chokuzoku kokka hoanbu na no da himitsu keisatsu yami ni magireru supai katsudou torishimariDiamond might be tough... but scientists looked at it and went "fuck that, we can make it tougher", 'cuz Wikipedia says we can make synthetic diamonds that are actually stronger than the real thing.
Whoever says that humanity sucks... is right, but humans are also fucking awesome and we should respect the ones among us who are bringing up our overall rating.
himitsu keisatsu seifu chokuzoku kokka hoanbu na no da himitsu keisatsu yami ni magireru supai katsudou torishimariStill, the hardest material in our universe is the matter that makes up the core of a neutron star, which is something we'll never surpass, due to its hardness/toughness being a factor of the insane density, and by consequence mass, it possesses. Even a bit of it the size of a sugar cube could break through a table...and possibly the floor under said table.
Let's see if you can get past my Beelzemon. Mephiles, WARP SHINKA!Neutron stars are pretty much giant atomic nuclei. The mass of an atom is in its nucleus. And the way we usually visualize atoms, with electrons dancing around a nucleus over half the diameter of the whole atom, is quite wrong.
Now, the Sun. The Sun is quite big, about 600,000 km from its surface to its center, so, the distance between Earth and Moon would be the equivalent of getting halfway into the Sun's depths. 4 light seconds of diameter. The Sun is also far away for our standards, 150 million km away, or, going by light speed, about 8 light-minutes away. This distance is known as an astronomic unit (AU).
Now, remember Pluto? The ex-planet we got high resolution pictures of last year, and the probe that took them was one launched in 2006, back when Pluto was a planet? Well, Pluto's orbit is 40 AU away from the Sun; over 5 light-hours away. Or, in a image set to scale where our Moon is a pixel, it'd take 17 minutes of scrolling to get from the Sun to Pluto.
And why am I going into that abstraction? Well, now, back to atoms: If the nucleus of a hydrogen atom (that's it, a proton) was the size of the Sun, how far away would the electron be?
It'd be 11 times further away than Pluto is to the Sun. 440 AU. Over 2 light-days.
And now, another 2 concepts: The mass of an atom resides in its nucleus, and density is mass/volume. Volume is measured in cubic units, so it increases exponentially.
Neutron stars are made out of pretty much atom nuclei, without the electrons. They have the mass of the atoms it was made out of, but almost none of the volume. So, their density just feels illogical.
Neutron stars are not matter in the usual sense. They lack chemistry, as chemistry is pretty much how atoms and their peculiar electron configurations interact with each other. Neutron stars are physics. There are no elemental properties, there is just density. Anything more dense and it collapses spacetime causing an event horizon.
I believe it would be, and I quote:
WHAT THE FUCK IS WRONG WITH ALL OF YOU!?
....Of course, I may be a little off.
One Strip! One Strip!I mean, the thing with diamond is that while it's tough, it also has planes of weakness.
You can't cut a diamond easily, but if you hit it with a hammer it'll break into smaller pieces.
Like. "Hardness" refers to something's resistance to scratching. The ability to cut something.
That's slightly different than. I mean. Call it "toughness". Resistance to breaking/smashing. Diamonds are slightly brittle.
Diamond is Unbreakable yet Star Platinum can punch through teeth as hard as diamonds.
Truly, Diamond is not Crash.
Let the joy of love give you an answer! Check out my book!Although that does raise the question of how Beerus will explain his absence to Goku.
This song needs more love.

So, diamond is the hardest material on Earth, and obsidian is the sharpest material on Earth... what's the strongest material on Earth?
