I think he means the something like the matter neutrino is in the muon state and the animatter electron is in the anti-tau state. if this were the case i would imagine that they would not annihilate. Just looked up the masses of neutrinos. they all have different masses so am i right in thinking that they speed up an slow down as they change states?

prop-1,2,3-triol or glycerine IIRC.

Maybe you should consult swansont or one of the other phyisicists from now on. I'm a chemist at heart and i won't be on much for a couple of days(Going to my cousins in england and they only have 18.8kbps dial-up shudder.). hope you find some answers.

why didn't they just ask the Pakistan authorities to send in a few of thier troops to capture/kill him. would have been a lot less death and no damage done when they found out he wasn't there.

well technically a block of lead this size would collapse into a supermassive blackhole and since neutrinos interact with gravity they would all be stopped.

S.I. Units

This is true. But they do not interact through the strong force. They only interact through the weak force and maybe gravity. Although the constant is = to the speed of light, its just a number. it doesn't matter if the particle can't go faster than the number or if it can't even go faster than 1 m/s its merely the relation of energy to mass. Yup basic algebra. But i still think your definition between matter and mass are a little bit fuzzy. it can be a hard concept to grasp sometimes. you can have mass without matter but you can't have matter without mass. Ehh no there is the same amount of strong force its just that it cannot interact between the fission products as they are too far away. when you pull(or push depending on how you look at it) the fission products out of the reach of the strong force of a particle the energy used (which gets stored as potential energy) gets released and in the case of muons actually goes to form 2 quarks(well a quark and its antiquark). in a uranium atom the fission products move out of the strong force's potential well of hundereds of particles so lots of energy gets released in light and kinetic energy. I'll get on to those tomorrow unless someone else does them for me. Bed time for me i think my mind is numb from studying.

since in the rest frame of earth the whole frame is accelerating. subtract this acceleration and the blackhole accelerates towards earth at 9.81 ms^-2

First off, WOW! this is a much better description than you started off with, well done. Now to buisness. There are a few sub atomic particles that have mass that exist without the strong force. neutrionos. remarkable unreactive. He didn't need to as the potential energies these forces cause would be measured in the mass and if the matter is completely converted to energy (annihilation) then this mass(energy) will be released as well. E=mc^2 is merely an equation which relates mass and energy. Not sure how this works in your head. Can you explain it a bit more please. Its more of the more matter the more energy that is stored as mass. Yes but this energy manifests itself as mass. if you took this energy away but kept the matter there somehow. the matter would appear less massive. Maybe its time to introduce you to one of the more mindboggling concepts of this equation. Mass and energy are the same thing. basically the equation is saying Energy=Mass multiplied by some constant(which works out to be c^2) Again Energy is Mass. Yeah ehhh... still don't get that one. You'll need to explain this a bit more. OK using this equation i will now work out the difference caused (note: i'm doing this on the fly so i on't know if there will be meaningful results. now in the fission of U-235(m=3.902995712694255e-25 kg)is hit by a neutron(m=1.66053886 e-27 kg) total mass =3.919601101294255e-25 kg the atom fissions into Kr-92(m=1.3602052167944938e-25 kg), Ba-141(m=2.3413597926e-25 kg) and 3neutrons(m = 4.98161658e-27 kg) total mass = 3.7513811751944938e-25 kg difference in mass = 1.682199260997612e-26kg according to einstein the energy released per atom should be (1.682199260997612e-26 * 299,792,458^2) 1.5118852974888513201329405194757e-9 J which is what we see. and i don't have enough time to finish right now so i'll be back later. EDIT: Found some more time. right now for your equation: MC=O ; 1.682199260997612e-26 kg * 299,792,458 m/s =5.04310651e-18 kg m s^-1 M/O=R ; 1.682199260997612e-26/5.04310651e-18= 3.335640954e-9(too little time to work out units will do it later) A=M-R(C^2); 1.682199260997612e-26 - 3.335640954e-9(299,792,458^2) = -299792458.2 oh dear we have a negative energy. something must have crapped up. anyone want to check my maths cos i hope it wasn't me since i have a maths exam tomorrow. You probably need to work on this a bit more if its going to stand up in any way shape or form. got to go now.

by definition eternity is never ending so no. this more of a philosophical question

well you could buy a bag of marsh mallows and eat them when your watching the ocilloscope.b

put a load of marshmallows in and your should see "hotspots" where the marshmallows melt quickly and cold spots where the marshmallows take longer EDIT: Oh yeah almost forgot this, Then eat the marshmallows .

Its the reason that it says "DO NOT OPERATE HEAVY MACHINERY" on the box. And, it says side efects are rare so you might be the 1 in a million person who actually gets side effects. One of my friends gets reall dizzy after he takes those things and his doctor told him never to take it again. So i'd cut down on your usage if they are affecting your health/mind.

1. Its already defined that Chemistry doesn't study the interaction in the nuclei of atoms to any great detail because its not a chemical reaction. 2. Hydrogen bonding in cells is already very well reasearched and is in no way a "new frontier in chemistry" its been around for 100+ years already. 3. Are you copying this from somewhere?

Glad i could help. Wikipedia is a REALLY good place to start. its got all sorts of stuff about all the sciences and is free. I wouldn't start buying books until your trying to learn the more advanced aspects of whatever your studying. Wikipedia

The what degree of vacuum part; Yes. The what type of sound part; No.

the speed limit comes from E=mc^2 the more kinetic energy you pump in the more mass it gets. the closer to c you get the faster the mass goes up. to travel at the speed of light you would need infinite energy.

if you smash two smaller nuclei eg two lead atoms hard enough they stick together.

Didn't go anywhere its chemical arrangement merely changed. I'm good a chemistry so i'll explain this in chemical terms since it is a chemical reaction. Also, firewood is perhaps a bit complex for this(loads of different chemicals in it) so I will use the combustion of methane. If we take the reaction formula for the combustion of methane: CH4 + 2O2 --> CO2 + 2H2O + energy We see that no matter has been consumed as it has the exact same number of atoms on either side. CH4 and O2 have unstable bonds that have quite a bit of energy stored in them. this energy manifests itself as MASS but NOT MATTER. it seems you have these definitions slightly confused. when the atoms rearrange themselves to CO2 and 2H2O the energy is emitted in the form of kinetic energy and photons. Since the energy has left the system there is a small reduction in MASS but not MATTER. all the atoms are still there just like in firewood. the carbon dioxide will escape if it is not a closed system(which is likely) and may lead to the appearence of mass and matter loss but the gas is merely in the atmosphere. This is true but absolutely nothing disapeared at all. Yes but NO MATTER was converted. It was just one form of energy being changed into another form of energy(potential into heat and light). This is another example of confusing terms here. MASS is not always MATTER. Here are some links explaining them. http://en.wikipedia.org/wiki/Mass http://en.wikipedia.org/wiki/Matter Lets say mercury at 4K. At this temperature there is no resistance. This is electrical resistance and has little to do with mass --> energy conversions. You show that you are learning(Which is a good thing, means you are not a crackpot) and are asking some good questions. To discuss these things wit someone who shows even a tiny bit of understanding and learning is always good. You do not need resistance for interaction. The earth is interacting with the sun but there is no resistance between them. An electron will interact with the nucleus of an atom but there is no resistance. Strong force does not sustain most of the mass. particles can have mass and not be affected by the strong force. There is no second force that i am aware of although swansont may be able to answer it better than me. Mass does not mean that the strong force is necessarily there. Keep up the good questions.

This is merely an analogy to what it is like. The "fabric" can be thought of a being a representation of the gravitational potential energy throughout the "space". since most systems prefer to have as little potential energy as possible they move "down" the gravitational well and gain velocity. It is wise to not take analogies as a literal representation of a theory. It is merely describing something in laymans terms.

as the tangental velocitcy(which is a velocty realted to angular velocity) approaches c it takes more energy to speed the particle up. We also have linear accelerators which cannot accelerate anything above c. if relativity was not true then the particles from the linear accelerators would end up at well over 30c.

D is deuterium the isotope of hydrogen with a neutron as well. So DCl is Deuterium Chloride. the reaction would be slightly slower but not enough for you to percieve.

yeah it shows the core is positively charged as it is alpha pariticles that it deflects. Suprised that you weren't sure on that one athiest being a physics expert and all...

swansont just explained it. its chemically sound. as a side note: If you take it to extremes it will eventual drop to 0 as the intensity becomes enough to ignite the plant.
