[@ashlandwithouttheshd]

My body is composed of zero-energy particles

[@niks660097]

same..

[@seantiz]

Mr. Srominger’s passion has a childlike, open hearted enthusiasm that is magnetic and engaging.

[@jsogman]

Any relationship or comparison with Tachyons? I.e. any overlapping hypothetical curiosity/discussion here if we look at the properties of both?

[@qbtc]

At 1:50, Andrew misspoke. Energy of a particle is Planck's constant times its frequency which is the inverse of its wavelength.

[@hhhotyg]

I can imagine an infinitely stretched particle. How about applying elasticity, one of the properties we usually observe, to particles? What if the particle is like a rubber ball or a rubber ball with goo on it? A rubber ball deprived of energy takes on a hard and compressed shape, and conversely, when energy is applied, it may stretch and sway like a string.

[@joshallen4848]

You're an infinity stretched particle.

[@011001010010]

replace the word 'stretched' with 'collapsed' in regards to a wavelength. and the comparison no longer makes sense. not sure if these two concepts are related. what does it mean to 'apply elasticity?' and why would you?

[@jjeKKell]

Or... replace the word particle with voxel and treat it as a point in space instead 🤔 that then stretches to infiniti upon any particle reaction, embedding angular momentum onto particle(s) as it does.

[@vagabondcaleb8915]

Infinite...Or infinitely divisible? Or infinitely iteratable? And is there a difference?

[@stevenguevara2184]

By the end of the quote I am hopelessly lost.

[@OMGitsjustperfect]

Do these zero energy angle momentum conserving particles have an effect on mass? If so, could this be an explanation for dark matter? (I am obviously a complete layman)

[@HolyMith]

Unfortunately not. Dark matter is localised, so it "clumps up" in different regions. Infinite wavelength particles would be highly homogeneous (distributed). Being massless bosons, they would be travelling at the speed of light, meaning they would rapidly disperse, an effect we don't see with dark matter. And that's not to mention the insane density of particles that would be needed to have an observable gravitational effect. They would have zero values for all energy components of the energy-momentum tensor, and extremely small values for spin (the only momentum they have). I'm not so sure about dark energy however.

[@Trizzer89]

How can we know about soft gravitons if gravitons dont exist?

[@stephenpomfret5068]

Nobody knows what gravity is.

[@JurOz1980]

It could be handy for communication then

[@jjeKKell]

Sounds like a voxel (maybe not so much a particle but a point). Like a television pixel provides potential color - in this case, the vacuum/fabric of space, waiting for an interaction, then providing potential angular momentum in exchange.

[@jjeKKell]

replace the word particle with voxel and treat it as a point in space instead 🤔 that then stretches to infiniti upon any particle reaction, embedding angular momentum onto particle(s) as it does.

[@edh615]

if you learn quantum field theory you'll know particles are just excitations of the underlying fields.

[@jjeKKell]

@@edh615 yes but might that excitation at the point of occurrence exchange or impart certain information upon or from the vacuum of space itself?

[@edh615]

@@jjeKKell you could think of it that way, one can represent that with Feynman diagrams, for example electron-positron anahilation generating a photon.

[@jjeKKell]

@@edh615 and, might these "zero-energy excitations" be a measure of space-time imprinting angular momentum on the reaction?

[@supamatta9207]

It s missing an number and you divide the suze of tge univers bya notation and inverse amplitude of a zero mass particle.!?

[@ramonalejano671]

How can a zero-energy particle have an infinite wavelength when our universe is finite? Mathematically, this make sense. But physically? There is no such thing. Could it be that a zero-energy particle is just a temporary state then either become positive or negative energy particle? Further zero-energy particle has infinite wavelength because it is not moving? Could it be at zero degree Kelvin? The lowest attained was 38 picokelvins. Could negative-energy make FTL possible? Like putting a negative-energy generator in front of a body?

[@upchurch231]

So can a soft particle be dark matter?

[@martinw245]

No. I would imagine if it has zero energy it logically has zero mass.

[@websurfer352]

But information is a boundary condition?? Unless each of these zero-energy particles store exactly the same information as every other zero-energy particle?? Because if each of these particles stored exactly the same information then each bit of that information would not be bounded dimensionally or it would not be characteristic of any particular particle it would be common to all and that would make the information not be a boundary condition?? Cause if particle A had information Z and particle B had information N, then information Z and N are 8:18 distinct and characteristic of particles A and B?? But if both had the same information Z then the particles can be considered the same particle, there would be no boundaries in distinction terms of information each stored??

[@OfTheVoid]

I thought 'Gravitons' have never been actually observed/discovered, and 'Gravity' is still an unproven theory? Gravitons are the Quanta of Gravity, but if Gravity is an unproven theory then so are the Quanta of Gravity

[@richardede9594]

Like the particles - I understood zero of this video.

[@websurfer352]

A particle with zero-energy would not be localized at any particular location since zero-energy is not quantifiable?? So, you consider spears out all over the universe with 100% possibility, but it could not be a spike in a probability wave??

[@bigpicture3]

This is getting weirder by the day. It has implications for how "entanglement", "super position", "mass energy equivalent" etc. actually work. Maybe even needs an "information / energy / mass" equivalent equation. It is encroaching on "consciousness" itself, and what is its actual nature. Need a "consciousness", "information" relationship equation-understanding. That small and large, and local and non-local may only be imaginary concepts.

[@AfonsoCL]

Consciousness has never and will never play a role in physics. That's your personal, and incorrect, interpretation of the discussion.

[@bigpicture3]

@@AfonsoCL Well isn't that the pure absurdity of the whole discussion and of science in general. Trying to UNDERSTAND something, while ignoring the MECHANISM OF UNDERSTANDING. (consciousness) That only makes sense to idiots. And even in the face of their double slit experiments that suggests that "consciousness" plays a key part of what is observed, they still choose to ignore it. That such as the "entanglement" phenomena would not suggest that time is not real, and consciousness is somehow creating that illusion of time. Or conversely the implied between distance does not exist, and consciousness is somehow creating the illusion of spatial distance. Only idiots would try to create an airplane while ignoring the properties of air.

[@ufcprophet40]

I understood everything

[@LBTennis]

Your CTE infested brain just thinks it did

[@ufcprophet40]

@@LBTennis and your primitive brain didn’t get that it was a sarcastic remark.

[@Mercury6_]

My brainn broke

[@johnlucich5026]

AI MEANS UNDERSTANDING THINGS WE CANT SEE AFTER THINGS WE CAN SEE ! ?

[@stillnessinmovement]

this sounds exactly like a variety of spiritual documents from different groups. we are much more interconnected than we realize...

[@chrisorchard4041]

what Lex never gets clear with him about - is almost all of what he spoke about only exists in his imagination - or other physicists imagination.

[@heim_ost]

Elderly Jason Bateman

[@just_one_opinion]

This guy and Sean Carroll both talk about "gravitons" like they are a Thing?! Why!!!

[@j4pp1n3]

Have they yet got 72 as an answer for the black hole hair thing?

[@Q_QQ_Q]

space videos after aella onlyfans . 😂😂

[@appa609]

I don't see how a zero energy nonlocal noninteracting particle makes any difference

[@spookmineer]

Conservation of angular momentum?

[@maxtroy]

He sounds like bill gates

[@NathansHVAC]

Infinities in the real world don't make sense. Only God is infinite.

[@TheKingsMindset]

You have waaay too much videos about space man...

[@darksidehendry7587]

Space is important

[@mobouazzati1843]

Can’t have to much videos about space :)

[@TheKingsMindset]

@@mobouazzati1843 space is fake brother. Turn back to God. Not to zionist NASA

[@yetanotherbob7767]

If you have a problem with that, than you should suggest the alternative... What subject would you like instead of space maaaaan, i mean he might listen to you and make 7 podcasts about 16 century literature or fishing or something that you dont care about at all instead of doing space maaaaan, i know that your problem is amount but still your comment isn't very helpful and maybe you dont give a fck about helping him but heres the problem, by helping him you help yourself - git more insights into things you are interested into maaaaaaaan.
