ok... i wonder if someone else her knows what im talking about.... ok, sometimes when im high, like everyone else, my vision is differant well, when im high, what i see, instead of objects, is little extremely tiny dots floating and grouping together to form the objects that i see, and that got me thinking. what is the relation between mass and energy? being only 15 years old i dont know much about about science like that. but what i think is that matter itself is energy, and vice versa. what it seems like is almost that energy floats around in space, occasionally grouping together to form matter and objects. it also seems like the energy that forms matter is constanly replaces, and the matter looks and feels the same, but is only a memory. am i just going crazy or does someone know what im talking about?
Don't know what you taking about, I tend to fall asleep. Though if it helps matter and energy are essentially the same thing and can be converted from one to the other, thats how a nuke works, you turn a small amount of matter into a huge amount of energy.
I forgot, the exact relation is E=mc^2 its quite a famous relation equation you've probably heard of it.
To expound on the equation, "E" represents energy, "m" is mass, and "c" is the speed of light. Seeing as the value of "c" is extremely large, you can see that even a tiny amount of mass is equivalent to a tremendous amount of energy.
But all molecules are not the same! And this pertains so minute that, even though some energy sources are comparatively the same, a wood burniing fire will behave differently than one of gas. So far as how things appeared to the 15 yr old while he was high, I think his brain's malfunctioning. His molecules were massive.
The "energy density" of a fuel which burns has nothing to do with the equivalence of mass and energy as being discussed here. The burning of a fuel does NOT convert mass into energy, it is simply an exothermic chemical reaction that converts matter from one form into another. Mass is conserved. If you were to capture all the gases, ashes, and soot that come from the combustion, they would weigh the same as the fuel and oxygen that went into the reaction. No mass is lost, and none is gained. A nuclear reaction such as an atomic bomb exploding actually converts some percentage of the mass of the fissionable material directly to energy. The total weight of all the fission products generated is somewhat less than the original mass of plutonium or uranium. The "missing mass" was converted into energy in the form of heat, light, and gamma rays. Not sure what those have to do with anything here. The "speckles" in a laser spot are interference patterns within the beam, caused by imperfections in the laser cavity that produced it.
Mass in basically frozen energy, the equation to work out how much energy is frozen is as Fat tony said E=MC^2 In other words the energy is its mass x the speed of light x the speed of light. Big number. This is mainly used to create particles is in particle colliders and they using it to find the Higgs Boson. The equation they are using is Energy needed at collision to find Higgs Boson = Mass of Higgs Boson x speed of light x speed of light. This is why particle colliders are so damn huge. Blessings Sebbi
