Everything in our universe has mass - from the smallest atom to the largest star. But the amount of mass has remained constant throughout existence even during the birth and death of stars, planets and you. How can the universe grow while maintaining its mass? Todd Ramsey answers that question by unravelling the law of conservation of mass.
Lesson by Todd Ramsey, animation by Vegso/Banyai.

The video is talking about the Lw of Conservation of mass which basically tells us that mass can not change( increase or decrease) in an enclosed space. For example, let's say we put baking soda inside a balloon and put that balloon over a flask that already had vinegar inside. When the baking soda falls and creates a reaction with the vinegar there will be little to no decrease or increase in mass as the atoms are not able to disperse. The only reason the mass can change is if the atoms have dispersed but in an enclosed space there is no room for the atoms disperse, hence the reason for the lack of change in mass. I may be wrong but that is what I got from the video also the example is not provided in the video, it is an experiment that my school used to teach us this phenomenon so you may not want to use that! Hope this helps!

Yeah he doesn't spell out the part about what he means about man is being energy and matter. This is a very irritating bad habit whatever words you use what you need to say is that depending upon the arrangement it's going to change its weight. As some of the mass turns into energy the amount of mass that is attracted gravitationally to the Earth is reduced. Now I understand that some people believe that if this container prevents a infrared or just flight from getting out then the light will attract the Box to the Earth the heat in there. In other words this is hard for people to understand because the narrator has a script that accidentally or deliberately tries to keep this fact Secret. Historically the loss of mass that happens when you freeze water for example has been hidden from late Observers buy the expansion of the water into ice explaining why it floats. It would float even if it took up the same amount of space or slightly less. Liquid water has added weight per molecule because of the Heat that you have to add to ice to make it liquid. The weight of energy is of course easily solved for by dividing the equation Buy what's the variable for energy to remove it from the left side and then multiplying by m which replaces that e for energy with the m for Mass. So that means that on the right side of the equation you have M squared multiplied times c squared the speed of light and then of course you have to know what the units are as someone recently did the math for to prove what I am saying to be false but only in his mind.

You are forgetting the biggest question. What caused the big bang? If matter and energy can't be created, how did nothing explode into everything?
@Markus9705
@Markus9705 9 лет назад
Nothing exploded, and that the thing. The Big Bang is not an explosion of matter moving outward to fill an empty universe. Instead, space itself expands with time everywhere and increases the physical distance between two comoving points. In other words, the Big Bang is not an explosion in space, but rather an expansion of space.
@levishu991
@levishu991 9 лет назад
No shit sherlock! The big bang is more accurately described as "the everywhere stretch". I'm saying If matter and energy can't be created, then what caused all that energy to come into existance?
@Markus9705
@Markus9705 9 лет назад
Levshu Whovian The total amount of the Universe is actually zero, so no energy was ever need to "come into existence". There's a thing called negative energy, you know. This theory, the Zero-energy universe theory, states that the total energy in Universe is actually counteracted with negative potential energy. Since potential energy always is negative, it cancels out the positive energy.
@levishu991
@levishu991 9 лет назад
Do you have evidence that this "negative energy universe" exists? or is it just another thing someone made up to try to make sense of the contradicting nature of out universe? Also, what caused our universe to come into existence along with the negative energy to counteract it? or do objects at rest tend to stay at rest unless they happen to be a universe, in which case all bets are off.
@Markus9705
@Markus9705 9 лет назад
Levshu Whovian Really, "energy" itself does not really exist at all, but is rather the integral of the force with respect to the distance which the force acts.

@bcubed72
@bcubed72 7 лет назад
The laws of physics describe the physical universe. You're asking a question about "before the physical universe existed." (And, also, "before time existed.") Physics won't help; religion might help with the WHY, but not the HOW.
@ejerfurth8175
@ejerfurth8175 7 лет назад
bcubed72 Well, time isn't really a thing it is more like a measurement created by man to measure entropy. That was what Einstein proved with his theory of relativity. But I see what you are saying. Though I do have another question. If there were no natural laws how did the Big Bang bang (I know it wasn't a real explosion but like how were the quarks attracted to each other and how was there only a set amount of energy in the universe). In my mind the only way something like this would obey the laws of nature would have to be if a infinite source of energy existed out side our universe ( it would have to be outside because according to the first law of thermodynamics if energy exists than it must of come from an outside source.) But thank you for replying. I have had these questions for years.

mass comes from energy, E=mc^2

@wbrehaut 4 месяца назад
This equation describes how energy comes from mass, not the other way around.
@maartenpost1336
@maartenpost1336 9 лет назад
Since Einsteins E=mc^2 we know that mass is not conserved! Example: In a nuclear reaction mass is not conserved. But energy is. Always. This video is not wrong it's title is just misleading.

But energy and matter are just 2 sides of the same coin, so that comment is misleading.

why is science such a controversial topic.. I believe in God and all that, and science to me is really amazing. To think how far we have gone with the help of science really blows my mind sometimes. Cant we all just appreciate it for what it is? Yea, well thats not gonna happen... Humans will be humans

So how come when these molecules go through chemical reactions and explosions, they survive, but us humans are made out of the molecules, but when we go through chemical reactions and explosions, we don't survive, or are damaged?

@Markus9705
@Markus9705 9 лет назад
Both mass and energy can be created and destroyed in an isolated system. However, the total amount of the energy, plus the correspondent energy of the rest mass of particles in the system, is constant. Since when did "mass" became synonymous with "matter and energy"? All matter has mass, but all forms of energy haven't a propriety of mass, including but not limited to gauge bosons, the photon and the gluon. Thus, the mass in a system constantly changes, since blackbody radiation applies to all things hotter than zero Kelvins. If light is produced, than mass is lost, because photons have no mass. However, the _momentum_ in an isolated system is always conversed, except for very local events in quantum mechanics where the law of conservation of momentum actually is broken. However, these small fluctuations zeroes each other out, so overall, the momentum is conserved. And since when did the Big Bang became a literal "bang"? The Big Bang wasn't an explosion of matter into already existing space, but the very beginning of the expansion of spacetime itself.

***** At rest mass?
@Markus9705
@Markus9705 9 лет назад
***** No. Energy is mass times length squared divided by times squared. Mass is a fundamental physical quantity itself. You can easily see this if you consider the SI units for mass versus energy. Mass is measured the base unit kilogram but energy is measured in the derived unit Joule.

Gluons, photons, etc in a isolated system can contribute to the mass of the system itself, even if they don't have mass themselves.. An isolated system by definition does not give off black body radiation, neither does it absorb any (if it did it would be a closed system, not an isolated one). Think of it as a white body rather than a black body

Mass is defined as A. Amount of gravitational influence of an object B. Amount of momentum of object (for given velocity) Both of which "massless" particles posses a non zero amount of.
