ive checked other photogrtaphs, no bend

You all should learn this and figure out how to apply it to your model

A physical property is generally something we can directly measure in our world using rulers and such, something like god is nonphysical

the concept of 1+1 = 2 isnt necessarily physical

Okay I disagree something non physical just has to have no matter

i guess non physical is a bad word

god's don't exist so he can't be physical associate

?

More like

even if god exists he is non physical

Immaterial

an abrihamic god

@Cetstus that's better

Without matter

oh dear

If by nonmatterial you just mean zero mass

you mean a photon XD

still kinda weird though

Yeah

I would say immaterial things influence the material world but are unseen in the same we cant see the entire electro magnetic spectrum

Through energy vibrating at different frequencies

Interacting with material vibrations

they influence each other

Like an ocean dense vibrations sink to the bottom

Kinda

The bottom of the ocean is more dense

Than the top

@Fran

??

even though the EM spectrum is "immaterial" (which its not because photons) , the notion of something immaterial effecting something material makes no sense. there is no interaction there

But the EM spectrum does that all the time

@inky he's using immaterial to simply mean 'zero mass' not something outside of physical relaity

Yep

i wouldnt say that photons are fully zero mass, while depending on how you approach it a photon could be considered zero mass if its at rest, but they never are, they have energy and momentum: which means they must have mass

@Gwen @Fran ^

Energy has no mass yk

And momentum is energy

relativity

?

total enrgy of the system/particle is equal to the mass of the particle/system times the speed of light squared
