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?

There is no such thing as small. Everything is infinite and keeps getting smaller

I see too many guys thing of your beauty , but not what your point was. Everything is infinity, no matter how big we think the universe is, when we it in lets say 100 years, we will see things bigger than what we an see, now. And we will see smaller than particals, too.

Nutrinos are atomic sub particles that originated in Mexico discovered by Joselita And Raymundo Dominguez while observing a dying chicken and was later researched by Javier Dela Peña a gang member from MS13. Javier conducted his study after shooting dead an enemy gang member named Marcos Benitez from Latin Kings.

I still dont understand particle collides... We can't see beyond a particle so let's smash them into smaller pieces we can't see...

So we live in a world where we cannot define the word "life," everything is held together by undefinable concepts we call gravity or nuclear forces, there is no limit to infinity of size on either end, and now we think the smallest particles don't have to have size. And humanists curse religions as being superstition b/c they are based on faith, yet fail to comprehend that faith is all they also have. Everything we think we know is wrong. It is just inconvenient for the human mind to think it is not the ultimate in defining creation.

That is NOT how an electron microscope works !!! It scans the sample with and electron beam and measures the current as it travels across the sample. The image it the different levels of current measured ! This is also the reason electron microscopes don't work with insulators ! There isn't enough current to measure ! How can a physics channel get this wrong ? You explanation is more like how an X-Ray works, creating a shadow on the film, and would work good that explanation. Except that X-Rays do travel thru living material but some of the particles are blocked. String theory is based on what real world experiment ? None that I know of ! Kind of like Dark Matter. It exist but can't be seen ? The ether theory makes more sense ! How about you just ignored all the electrostatic and magnetic effects, so the mistake is covered by DARK MATTER, since they can't admit when they are WRONG ! And this coming from an Earth that changes about 1000 volts per meter of height. But electric charge doesn't matter ???

Do a video on why Supernatural Causation can not be confirmed and how we have no method by which to investigate it. Methodological Naturalism is superior to Philosophical Naturalism.

I prefer when you are physicsing (practical and physical demonstrations) rather than narrating other people's academic theories. I prefer when you conduct experiments that make me think hard and ask questions about something I had not seen before. I know physical demonstrations are expensive to make but that is what physicsing is all about - physical physics. Physics Girl, you have good physics and a good physique! Keep it up. Thanks.

There it is again folks the "Scientific WE" as in "we have" or "we now know" - Who is this WE? Is it a we that includes the hearers, as you say to the members of your family "We are a family" or does it exclude the hearers as in "We are going to beat you"?
julie Wallis (2 months ago)
Thunkful2 I take it to mean ‘we scientists’ but it could be taken as ‘we, mankind’ . Have you ever heard the saying “pick your battles” ? All the questions I come up with when watching Physics girl, and I’ve never wondered who the “we” are.

Raf galvão (2 months ago)
zero dimension/ no size does not make a point... inconceivable .. there's no a 2d object nor 1d no 0d. That's so mind blowing. What about when we measure the smallest distance we find out all particles disappear in one place to appear in other without intermediary location ? :d

Is it true that these particles pop in n out of existence...and shouldn't the smallest length in the universe be infinetely small ..how do we measure infinity...can Planck length be further divided...how do objects travel from ( let's say) Planck unit 1 to Planck unit 2 ...does it disappear at 1 and magically appear at 2 ...my head hurts

HI Girl i just want to know how to capture this Atom and its electron? In my experiment ordinary rubber or plastic becomes conductive or negative charged. Hope you can explain it to me why its happening i don't understand? thank you in advance

Title is a big lie You can’t see strings since photons would have to be such a short wavelength that the energy concentrated into it would make a kugelblitz therefore you can’t see strings
Mehdi Yasaee (3 months ago)
Such a great video. I specially liked the part from 4:27 describing the infinite forces and how string theory is "solving" the problem. So many videos on these topics either go too much into the maths or just barely get past the smashing particles together part. A video on how these elementary particles are measured in the LHC would be great, so hard to find information on them.

Nice video, but... @1:42 Didn't you mean, the more _energetic_ the particle, the smaller the wavelength? And, regarding String Theory, complained about in at least one previous comment, I find it interesting that String Theory seems to corroborate with ancient Vedic "knowledge" [quotes because who knows if it's true, but it sure seems to make a lot of sense]. But, unfortunately, I'm not enough of a scholar to defend my position--I mean, I read stuff, and some of it lingers, and I see correlations, but they are based on faint, and possibly faulty memories of stuff I read long ago, and have since forgotten the origins of.
