Laws of physics 'can change' depending on where you are in the universe | Mail Online
The new analysis of data from Hawaii's Keck telescope and Chile's Extremely Large Telescope, could have profound implications for our understanding of the universe.
The 'constancy' of physics is one of the most cherished principles in science - but the scientists say that the 'laws' we know may be the galactic equivalent of 'local by-laws' and things may work quite differently elsewhere.
The discovery - if true - violates one of the underlying principles of Einstein's theory of General Relativity, and has profound implications for our understanding of space and time.
The findings could mean that the universe is far bigger than we thought - possibly even infinite
Very funny, Scotty. Now beam down my clothes.
Again great find Altria
Since I've learned about Einstein in high school, and his formula to calculate the mass of a body that travels at speeds of light and near that, I still think he was wrong.
I can't remember the formula today anymore, but I remember he states that a particle moving at near the speed of light will increase it's mass.
I see that from his formula.
But then he makes a mistake (in my opinion), saying that a particle moving AT the speed of light will have infinite mass.
When HIS formula shows that its mass will be 0 (zero) AT the speed of light.
And this is seen in the light itself - wave light are particles also, and they have 0 (zero) mass (just because they move at the speed of light - in my opinion).
And I have always believed that things happen differently all over our universe.
We know that gravity affects the matter and time.
So close to big bodies, time & matter will be (behave) different from when in empty space..
But don't take me seriously.
I haven't got a clue.
The formula for the mass of an object, of rest mass m(0), as a function of its velocity in special relativity is
m = m(0) * γ.
The relativistic quantity γ tends to infinity as the magnitude of the velocity of the massive object tends to the speed of light. Thus at the speed of light, γ reads
γ = 1/0
which is a so-called indeterminate form in mathematics, with its meaning undefined. That being the case, the formula says nothing about what the mass of an object with a finite rest mass is at the speed of light, but it does suggest that it is impossible for it to travel at the speed of light, as it would require an infinite amount of energy to accelerate it to the speed of light. The formula certainly does not say that the mass will be zero. If you set v = c in the formula
γ = 1/√(1 - v²/c²)
you certainly do not get 0 as the result. You get the indeterminate form 1/0 (which some people often lazily read as infinity). Certainly γ → ∞ as
v → c.
It suggests also that because light quanta, or photons, move at the speed of light then they cannot be massive.
i knew that, but now i know why....thanks.
