Beyond molecules and atoms, how far down can we see below the wavelength of visible light? What is the smallest possible scale in the universe?

Some day humans will realize that they will never be on a small enough level to witness the smallest thing in the Universe . Size is infinite in both directions, large or small. EATON CONJECTURE: EVERY EVEN INTEGER GREATER THEN 12 HAS MORE THEN ONE SUM OF TWO PRIMES. THIS HELPS PROVE THE GOLDBACH CONJECTURE.. THE EVEN INTEGER 1 TRILLION HAS OVER 1 BILLION DIFFERENT SUMS OF TWO PRIMES. SO HOW DO LARGER EVEN INTEGERS HAVE NO COMBINATIONS, IMPOSSIBLE.

You can always make something smaller.We are, our own limit.

If atoms are so small that they are invisible, then how can a group of atoms, molecules create things we can see?

Could you make a Quark microscope?
Lucius Chiaraviglio (1 month ago)
I could have sworn to having seen NBC News broadcast pictures of an array of uranium atoms imaged using a very high powered transmission electron microscope back in the mid 1970s. One of the electron microscopists where I work said that much resolution should have been possible even with 1970s electron microscope technology if you built one with a tube about 30 feet = 9.1 meters, which would be expensive and most likely non-standard, but certainly doable. More recently (1990s), atoms adsorbed on crystal surfaces have been imaged with atomic force micropes and/or scanning tunneling microscopes (and the results published in peer-reviewed journals). So imaging individual atoms is not so new.

wait how can quarks be created to bond to the two new quarks? i thought matter cannot be created nor destroyed

We got better science but we never got a better heart. In 6,000 years of history there are only 200 years without wars.  All this knowledge will be used to build new weapons and untimely destroy our planet. Jesus will come back commanding a fleet of starships. He will reset our planet, clean all the destruction and stablish a kingdom. No countries, no elections, no banks, etc...The Bible is not a religious book but a real report of our contact with beings from another planetary system. They told us that we will have a war that will destroy one third of the worlds population.

I was a bit confused with your height in planq's: did you mean 107, billion, septillion, or should it have been; 172, billion, septillion, meaning there is exactly a billion septillion planq's in a centimetre... -10 to the power of thirty nine meters is a lot of noughts and hard to enumerate in thousands of millions, let alone envisage as an actual distance!

What's the size of a photon? Can there ever only be a single photon?

this makes a loop... the things made up of quarks are made up of things, then those things are made up of other things, the the other things are made up of more things, then the list goes on!

Of course there are probably even smaller and smaller particles=waves adinfinatum

Suppose you illuminate a small object with ultraviolet light, with a frequency 3 times that of green visible light. That is supposed to be able to resolve objects 1/3 the size of what visible light can, right? Now suppose you mix the reflected UV light with another beam of UV, this one just 2 times the frequency of visible green light. It should produce sum and difference frequencies at 5x and 1x visible green light. The 1x difference frequency is visible light, so could that be directly observed? Sent through lenses or an optical microscope for a closer look? Could such a set-up resolve objects smaller than what could be seen directly in visible light?
Dan Schwartz (2 months ago)
Electrons, neutrinos, etc. could have a definite size but no internal structure, couldn't they?
JayZoop (2 months ago)
My theory is that you don’t have to have infinite smallness if the smallest object is a ENERGY FORCE rather than matter.
Cathix 003 (2 months ago)
Interesting how the smashing of particles looks like the Laniakea structure. Think about that for a minute. All those microscopic galactic filaments with a small chance of life blossoming in a billionth of a second and suddenly extinguished.

If we could image the string we would see that it is a life form meaning the universe is made of life.
Why planks length maths has to give theorized proof for that number in cubic solutions set. Somewhat related to number phi and constraints imposed in number theory. You can take any unit like meters foot or other units of length. An other hint is 2. Something and nothing.
Minus one by twelve cube.
Noble Carpenter (3 months ago)
I dont think we can do that. Now i could be wrong, but i think the energy it takes to see down that small is so great that the object you are observing becomes a black hole.

Co Parker (3 months ago)
Whatever was the smallest distance in the universe, could you not half that, and then that, and so on... ?
Co Parker (3 months ago)
@Ian Whitfield ...who knows ? But I agree with you. When we see how small we are relatively, look how far we can break ourselves down
Ian Whitfield (3 months ago)
@Co Parker The universe is infinitely big surely it must also be infinitely small.
Co Parker (3 months ago)
Maybe it could be divided infinitely ?
Just Looking (3 months ago)
@Co Parker A string is a circular line. So it has a 'point' thickness, but perhaps the length could divided?
Co Parker (3 months ago)
You think a string wouldn't be made up of tiny parts?

How do you image a probability???
Robert Pruitt (2 months ago)
You don't. Each time an electron hits it, it's location is resolved. Hit it with a million electrons and it gets resolved a million times, in a million different places. When you stack the images to make a complete picture, you have your probability "image".

Emerald Dragon (5 months ago)
I was actually kind of under the impression that quarks and electrons were composed of Planck strings, which themselves are composed purely of energy, in conjunction with part of Einstein's E=MC2 theory. Because the theoretical strings would be so close to massless (certainly not measurable by any technology we currently have), that would sort of balance out the speed of light squared part of the equation. But that's just my idea, and I have no clue if it already exists in a much more comprehensive and/or complete form.
Robert Pruitt (2 months ago)
Why would you be under that impression? You said it yourself, "theoretical". And TBH, they've been working on this model of string theory since the early 70s, with absolutely zero evidence that is remotely correct. In fact, it's not really even science by our understanding of it, because it's unfalsifiable. Maybe it's right, maybe it's not, but you really shouldn't be running around thinking it's a foregone conclusion that it's true.

Con: Talking to fast, not enough time to think through what was said, not enough visual support (by animations/pictures), went into (sparse but good) detail on some topics.. but missing detail on other topics. Pro: good examples, good- pictures, good-- animations, woman interested in science+, pretty woman interested in science++, pretty woman interested in science and understands it (as far as one can guess)+++* Grade: German

measure the smallest distance in the universe? what would be between that distance? wouldn't it be more universe? therefore, is this even possible?

Isn't it amazing how chemists such as Lavosier, Dalton, Medeleev, and other male chauvinist pigs, (uh coughing), I mean other great chemists were able to predict the bonding structures of atoms, and now all of that can be verified with technology? Hey cutie! If you ever want to buy me a cup of coffee. I mean, uh, yeah that's pretty good girl. You don't mind if I say I love you do you? I LOVE YOU! Thank you for the awesome video. :-)

I've heard it said that a string in string theory is so small compared to a proton that it's like comparing the average oak tree to the size of the solar system. Some drunk in an alley told me that. Not really, I just can't remember where I read it.
