Was Einstein Wrong?

Was Einstein Wrong? What is the neutrino particle which traveled faster than light?

Answer:

As we know it now; Neutrino is a neutral subatomic particle with a mass close to zero and half-integral spin, rarely reacting with normal matter.

Three types of neutrinos are known –

Einstein’s theory of relativity suggested that no particle can travel faster than light in vacuum.

If neutrino travels, there is something wrong and we have to make necessary amendments

If neutrino travels faster than light?

If neutrinos travel at the speed of light through a vacuum, and rarely interact with matter, how fast do they travel through the nucleus of an atom?

Matter, Antimatter and Einstein’s equation

It is my understanding that when antimatter comes in contact with matter that there is nothing left but pure energy.

And since energy and matter are interchangeable (E=Mc2) doesn’t that mean you are actually left with all matter and no antimatter?

Asked Ken

Answer:

The equation E = mc2 tells about mass – energy relation and both matter and antimatter has a positive mass.

Ideas on the Origin of Universe

Well, nobody knows it exactly. Physics and other sciences can explain How things go or went, not Why. Althought there is a theory, called the M theory or the 11 dimensions theory, that gives a kind of answer to this: the M theory says that the matter is made of little strings that vibrating give to the matter his properties. To ensure all the properties 10 dimensions are necessary: the classical 4 (3 for the space + time) and 6 circumvented dimensions. Well the 10 dimensions theory was not able to explain some phenomenons, as the divergences between relativity and quantum mechanics. in 1995 a phycisist found that assuming the existence of an 11th giant dimension, all was explained. think about this dimension as a giant room where there are sheets hanging from the ceiling. well these sheets are parallel realities. Our universe is in one of these “sheets”. In this frame we have the creation of a universe (a big bang) every time a sheet touches another sheet.

I’ve just described you the frontier of the theoretical physics.

Crystal Cleavage

Sly asks:

“what is crystal cleavage and what does it state about the nature of matter?”

Answer:

Cleavage, in mineralogy, is the tendency of crystalline materials to split along definite crystallographic structural planes. These planes of relative weakness are a result of the regular locations of atoms and ions in the crystal, which create smooth repeating surfaces that are visible both in the microscope and to the naked eye.Cleavage plane can be described as the tendency of crystals to split along specific structural planes.

Cleavage plane is used mainly for the identification of the minerals. It is used in the electronic industry and also helps in cutting gems.

Big Bang and the conservation of Mass

Harilal asked:

“During the big bang it is supposed that the small particles expanded in a very very small interval of time and there was nothing before that. If it is so, then how can it in be good agreement with law of conservation of mass?”

Ans:

After the Big Bang, the universe expanded rapidly. The big bang theory is not a theory which is completely resolved. There are many questions to be answered.

Further, mass alone is not conserved, it is mass+energy  which is conserved.

Energy can be converted into matter and vice versa. (E=mc^{2})

Dark Energy and Dark Matter are two widely discussed concepts in association with the Big Bang. These correspond to the mass (matter) and energy which we cannot account for by calculations and theory.

Further, BIGBANG is not the only possible cause of the Birth of Universe. There are many other possibilities.

Big Bang theory originated after the discovery that the universe is expanding. SO if we think in reverse direction, we can imagine that the entire universe was confined to an infinitesimally small (Compared to the present size of the universe) space. This idea started the theoritization of the Big Bang.
