Matter IS energy, and energy IS matter. I like to think of it as a phase transition, personally, but  I don't know exactly HOW it happens.

Real life applications: Nuclear power works because the mass of the products in a nuclear reaction is less than the mass of the reactants. The mass that is "lost" in these reactions is converted into energy.

The reason we use fission reactors is that it can be done at easily-attainable temperatures. Fusion, on the other hand, requires very high temperatures, such as those in the sun. We can replicate those temperatures using arrays of lasers that are all focused on the same point, and then nuclear fusion can take place. Unfortunately, at this point I don't think we've yielded a net gain in energy through fusion, so fusion reactors aren't feasible yet. In the future though, who knows?


They are working on a fusion reactor near San Diego, they are close to getting it online, It takes them like d days to create the molecularly perfect gold targets thy shoot with those lasers, looks promising.

what might blow your mind is  energy can not be created or destroyed just merely transformed :D  so everything here today was created at the big bang / expansion  and nothing has been added from that point just transformed into diffrent types of matter


" with out getting into anti matter / matter explosions  or  blacks holes taking matter out of the universe "


Nothing is taken out of the universe.. >.>
It is either transformed or condensed.

no one knows

we don't even know what gives mass to anything

it could be quite possible what we perceive as mass is energy. we hypothesize now that there is a web that when interacted with gives the illusion of something being solid.

why?

everyone knows that the main subatomic particles are electrons, protons and neutrons. electrons weighing i think 1.16 X10^-16. that is basically nothing. the protons and neutrons (which make up the nucleus) make up all the weight of an atom. inside the nucleus are quarks. you'd expect the quarks to add up to weigh as much as the nucleus. in reality they weigh nowhere near as much. in fact they weight about as much as the electrons. so where does mass or matter even come from? we think it's the higgs boson. we requires an inter connective web to explain it.

Particle accelerator: one of the examples would be electrons accelerated to high energies (high kinetic energy), and then smashed into a target. The result would be new particles that exceed the original mass of the electrons.
THIS IS ENERGY CONVERTED INTO MATTER


matter converted to energy has been explained a lot in this thread already, so I hope the particle accelerator will be a good complement :)

This post is a violation of the site rules and appropriate action was taken.

Anyone who said that burning something is converting matter into energy, you are stupid. I know you are going to refuse to accept the fact but it's true. I'm not going to explain why because you won't listen, you'll just say you're right and junk but you really are stupid. I wish you wouldn't vote because I bet you vote for people for stupid reasons. I also wish you wouldn't reproduce. Please don't vote or reproduce or post anything other than questions, you'll be less of a burden on the world this way.

you just show your own ignorance. of course burning something is converting it from matter into energy. not all of it for sure but depending on how well its burned a large part of it could transforming into what we call THERMAL RADIATION as well as ELECTROMAGNETIC RADIATION, also known as heat and light. both are forms of energy. electricity is not the only form of energy you imbecile.

E=mc^2 where c is the speed of light or 3x10^8 m/s so if you converted 1 kg (2.2 lbs) of mass into energy you would get 9x10^16 kJ or 25x10^12 kWh

To put that inot perspective, in 2006 the U.S. used 3,662,561,000 kWh per day. So using the energy from 1 kg, that is enough to power the U.S. at that kWh for 6825.8 years

A much more simplistic example would be, a log converted into fire, by burning the log you are creating radiant energy. Think as the element you are converting, (either mass to energy or vise-versa) as "fuel"

The how this happens its not within our grasp yet.


Burning a log is not converting matter into energy, if you burned a log and kept every piece of the log your mass would still be this same

EDIT: The explaination is that you are simply creating a chemical reaction, where a chemical reaction still stays as some form of mass, to convert to energy there is no more mass.

EDIT #2:After reading the whole thread it appears a lot of people think that burning wood or a piece of paper is an energy "thing", but it is not. Think about the gas in a car, it starts out as some sort of hydrocarbon C4H8 and when reacted with oxygen via fire it creats a CHEMICAL reaction that turns the hydrocarbon, oxygen and any other element in the air into different chemical compounds (i.e. H2O, CO2, CO). If burning a log was the changing of mass to energy, you would blow up your whole neighborhood

Hello ignorant heathen who has an idea in his head and will refuse to accept that he is wrong no matter what and I am a masochist for arguing and replying to your post.

Well here goes... When you burn something, anything, you are causing a chemical reaction. A chemical reaction can release or store energy in a molocule. When you, for example, burn a log; you are releasing chemical energy that was collected from the sun and through photosynthesis used to form carbon based molocules to for the plant. When a log burns, it's mass is combining with the mass of the oxygen in the air. Specifically the carbon in the molocules in the log is combining with the oxygen to form carbon monoxide. While this process happens it realeases the stored chemical energy by means of producing heat. We can see this in the observed fire, fire which is the very hot carbon monoxide gas and impurities found in the log glowing bright orange because it is so hot. During this process, there is no change to any atoms, only molocules, every bit of mass that is in the air and the log is conserved and changed into smoke and ash and carbon monoxide. This is called a chemical reaction and matter can not be created or destroyed in a chemical reaction.

I hope you can find the mental fortitude somewhere deep down to read and understand this though I very much doubt it.

Once again though, please don't reproduce if you value humanity's survival in the future.

for acting as high and mighty as you are perhaps you should try taking a look into this topic again.
1st) a combustion reaction is the reaction were talking about: where cellulose in wood (amongst other organic compounds) is reacting with oxygen. the energy from the reaction is stored in the bonds of the carbohydrates not just simply energy 'collected from the sun'. its specifically stored in the highly reduced carbohydrates of the plant.
2nd) a combustion reaction forms carbon dioxide gas, not monoxide
3rd) it glows orange because the amount of heat, free radicals, and transition state molecs the reaction produces causes electrons to rise to a state sufficient enough to emit visible light (in woods' [and many organic compounds] case orange) as they fall back down to their ground state.
copper for instance burns with a green flame even if it is burning at the same temperature as a wood flame. natural gas burns with a blue flame, which is why your stove is always blue, not orange, despite being capable of burning at comparable temperatures as wood
4th) im pretty sure that lone500 is trolling you

so please mr high and mighty don't reproduce if you value humanity's survival in the future
