One way to show that the spacetime interval is invariant under Lorentz transformations is by using the Lorentz transformation equations to calculate the interval in one frame of reference, and then transforming to another frame of reference using the same equations. If the interval remains the same in both frames, it demonstrates that the spacetime interval is invariant under Lorentz transformations.

What are the generators of the Lorentz group and how do they relate to the group's transformations?

The generators of the Lorentz group are the angular momentum and boost operators. These generators correspond to the rotations and boosts in spacetime that are part of the Lorentz transformations. The generators dictate how the group's transformations act on spacetime coordinates and physical quantities.


What are the Lorentz group generators and how do they relate to the symmetries of spacetime transformations?

The Lorentz group generators are mathematical operators that describe the symmetries of spacetime transformations in special relativity. They represent rotations and boosts in spacetime. These generators are related to the symmetries of spacetime transformations because they help us understand how physical laws remain the same under different coordinate systems and observer perspectives.


What is the significance of the Lorentz algebra in the context of theoretical physics?

The Lorentz algebra is significant in theoretical physics because it describes the symmetries of spacetime in special relativity. It helps us understand how physical laws remain the same under different inertial frames of reference, leading to important concepts like relativistic transformations and conservation laws.


What is the significance of the Lorentz invariant phase space in the context of particle physics?

The Lorentz invariant phase space is important in particle physics because it allows for the accurate description of particle interactions and calculations of their properties regardless of the observer's frame of reference. This concept helps maintain consistency in measurements and predictions in the field of particle physics.


Is time dialation exponential or linear?

Time dilation, which can be derived from the Lorentz transformations is t'=t/sqrt(1-v^2/c^2) where t is the time interval in the rest frame, and t' is the interval in the lab frame. This relationship is neither linear or exponential in v.

What happens to the invariant quantities in special relativity?

It depends on what these invariant quantities are. It is not enough to specify that something is invariant, you also need to specify under which operation these quantities do not change (= are invariant). In special relativity there is an operation called a Lorentz transformation which applies the effects of a speed increase, thus applying time dilatation and length contraction. A Lorentz invariant quantity is a quantity which remains the same under this transformation, i.e. it has the same value for every observer in an inertial frame. Examples of such invariants are the lengths of four-vectors, the generalizations of the common 3-dimensional vectors such as those indicating place and momentum. For example the 3d-vector for location (x,y,z) is joined with another quantity for the time dimension into a 4-vector whose length is Lorentz invariant. There are more Lorentz invariant quantities, some of them quite complex.

What is Fitzgerald contraction in physics?

The Lorentz-Fitzgerald transformations arethat measured distance contracts in the direction of motionthat the relative time of interactions slows in a moving reference framethat mass increases with velocitySpecifically, that these all change such that measures of the speed of light will be constant in any reference frame.George Francis FitzGerald proposed the general idea of these transformations to explain some odd experimental results. They were given formal expression by W. Voigt, but such expressions were independently generated by Hendrik Antoon Lorentz. Henri Poincare, proceeding from Lorentz's effort, named them for Lorentz.

Why each mass has gravity?

This cannot be answered within the Newtonian framework because gravity just exists, it is not caused by anything. It is a curious coincidence that inertial and gravitational masses are equal. If we are willing to venture a bit further into quantum field theory however, an approximate answer may be formulated. I say approximate because a full answer would require an understanding of a quantum mechanical description of gravity and this has not yet been obtained. But, according to quantum field theory gravity is caused by so-called local Lorentz invariance (or local supersymmetry if you are feeling fancy and like supersymmetry). What does this mean? This means the laws of nature are invariant under transformations of the Lorentz (a mathematical group describing spacetime rotations and boosts) group. The argument is a bit technical I'm afraid, but you can show that this leads directly towards a description of gravity in agreement with Einstein's.
