If there is not a conservation of mass, then what happens to higgs-bosons? Are they destroyed, or decay into something else (if that is even possible...)?
montadhar said:Is there a conservation of mass at all ? I thought the conservation is for energy.
Drakkith said:Conservation of mass IS conservation of energy. The best example I can think of is in electron-positron annihilation that produces 2 gamma ray photons. The rest mass of both particles is converted into energy and radiated away. The mass is not gone however, as any system that includes those photons still has the exact same mass, it has simply moved.
montadhar said:I doubt that can be called a conservation of mass, it has the same energy converted from mass-energy into photons. But photon's mass are 0
SneakyG said:There is not a conservation of mass, but there is for energy.
Drakkith said:I don't think that is correct: http://en.wikipedia.org/wiki/Mass_conservation

Drakkith said:I'm not sure I see your point. This is exactly what I've been saying.
montadhar said:no it is not. I get what you are trying to say, but it is not right to say that.
If there was a conservation of mass, then if you measure the mass of the universe at anytime it will always show the same exact number.
But that is not the case, because of the Electron-Positron example. If a pair annihilated and then you measure the mass of the universe, it will show a different number
Drakkith said:No, this is 100% wrong. IF we could measure the mass of the universe, it would be exactly the same before AND after the annihilation of the electron-positron. Energy has mass and it is conserved.
montadhar said:If what you say is true, then Photons are massive, and they shouldn't move at c
Drakkith said:Photons have no REST mass. They have energy and they do, in fact, contribute to gravitation.
As an example, if you take a box made out of perfect mirrors and put light in it, it will have MORE mass than an identical box with no light in it.
http://en.wikipedia.org/wiki/Conservation_of_massThe principle of matter conservation may be considered as an approximate physical law that is true only in the classical sense ... when particles that are considered to be "matter" (such as electrons and positrons) are annihilated to make photons (which are often not considered matter) then conservation of matter does not take place, even in isolated systems.
http://en.wikipedia.org/wiki/Conservation_of_energyIt was found that particles that have rest mass, and those that do not, are subject to interconversions. There can occur creation and annihilation of (ponderable) matter particles, and imponderable non-matter particles. Matter is then not conserved. Matter particles (such as electrons) can be converted to non-matter (such as photons), or even into potential or kinetic energy.
Higgs Boson Conservation is a fundamental principle in particle physics that states that the total number of Higgs Bosons in a closed system must remain constant over time.
Higgs Boson Conservation is important because it is a fundamental rule of nature that governs the behavior of particles and helps us understand the fundamental building blocks of the universe.
The Higgs Field is responsible for giving particles their mass, and the Higgs Boson is the particle associated with this field. Therefore, Higgs Boson Conservation is closely related to the Higgs Field as it ensures that the number of Higgs Bosons remains constant, thereby ensuring a consistent mass for particles.
The discovery of the Higgs Boson in 2012 by the Large Hadron Collider (LHC) at CERN provided strong evidence for the existence of the Higgs Field and its associated particle, the Higgs Boson. The consistency of experimental data with the predictions of the Standard Model also supports the concept of Higgs Boson Conservation.
According to the Standard Model of particle physics, Higgs Boson Conservation is a fundamental law and cannot be violated. However, some theories beyond the Standard Model suggest the possibility of Higgs Boson decay or other processes that could violate Higgs Boson Conservation. These theories are currently being tested and studied by scientists.
