Wass up hommies

thanks again. I think the mathematics became too difficult for me, unfortunately. although I'm strong believer that understanding of things has almost nothing to do with math... but anyways, thank you, and the rest

you can show me on that equation, how the mathematics works that the time of the origin fits time of the arrival PLUS time it took the wave to get there.

Great! much thanks! now about the equation. the distance between A and B let's say 100 km. the speed, 50 km per hour. the time to make the distance - 2 hours. (B-A)/50=2 (distance/speed=time). now how time, in the maxwill equation, gets a negative value when there is no such thing as negative...

thanks again :) can you elaborate on what is the meaning of the potential that is advancing. what is that advances, is it a virtual photons, a disturbance in an electromagnetic field, a charged particle. and it released before its emission and get to the source or to another point in space? if...

THANKS; you added the equations, which are hard for me to understand but the last few lines are great help! can you elaborate more? make an example? analogy? are we talking about electron moving, magnet, electromagnet wave from the antenna? are you also dealing with philosophy of physics/time?

thank you. do you agree with the following paragraph: "The resulting wave appears to have a preferred time direction, because it respects causality. However, this is only an illusion. Indeed, it is always possible to reverse the time direction by simply exchanging the labels emitter and...

"of the two types of solutions which the Maxwell equations yield for the wave equation, the retarded and advanced potentials, only the retarded field seems to have a physical meaning," let's start please with basic (and detailed as possible for the knowledgeable layman! p.s-which equation is...

"Metabolism is an encompassing word to describe the chemical reactions occurring within a cell to sustain life. The subsets are referred to as anabolism ( no oxygen required ) and catabolism ( uses oxygen ). Catabolic reactions break down complex molecules into smaller ones. You use catabolic...

no, I'm asking what is basic metabolic? using energy? for what purpose?

"To maintain basic metabolic" i'm not sure why would they need that. as many creatures even more complex than plant embryo can completely freeze and later when temperature is good enough the chemicals in them start moving and they back to life. so what is and why they need to do it immediately...

how? thanks

thanks why would the embryo use food if it cannot and need not to grow (while dormant)?

hi anyone and everyone! why do seeds need oxygen before they grow, in the time they are waiting for the right conditions to grow thanks

according to einstein the mass go straight in the curved space because the sun makes the space curved and so the Earth circle the sun. but i don't understand why this "geometrical" explanation is a replacement for the gravity. how does the mass (of the sun for example) makes the space curved...
