## What is CT in Minkowski diagram?

The blue line describes an object moving with constant speed v to the right, such as a moving observer. This blue line labelled ct′ may be interpreted as the time axis for the second observer. Together with the x axis, which is identical for both observers, it represents their coordinate system.

## What do you mean by Minkowski space?

In mathematical physics, Minkowski space (or Minkowski spacetime) (/mɪŋˈkɔːfski, -ˈkɒf-/) is a combination of three-dimensional Euclidean space and time into a four-dimensional manifold where the spacetime interval between any two events is independent of the inertial frame of reference in which they are recorded.

## Why are Lorentz transformations linear?

As in the Galilean transformation, the Lorentz transformation is linear since the relative velocity of the reference frames is constant as a vector; otherwise, inertial forces would appear. They are called inertial or Galilean reference frames.

## Which of the following are the consequences of Lorentz transformations?

One of the most striking consequences of the Lorentz transformation is that simultaneity as a universal concept has to be abandoned. Simultaneity is also relative.

## Why is it called Lorentz transformation?

The transformations are named after the Dutch physicist Hendrik Lorentz. The transformations connect the space and time coordinates of an event as measured by an observer in each frame. They supersede the Galilean transformation of Newtonian physics, which assumes an absolute space and time (see Galilean relativity).

## What is twin paradox in relativity?

twin paradox, an apparent anomaly that arises from the treatment of time in German-born physicist Albert Einstein’s theory of special relativity. According to relativity, time runs more slowly on her spacecraft than it does on Earth; therefore, when she returns to Earth, she will be younger than her Earth-bound sister.

## What is CT in relativity?

Time is measured ct in relativity simply to measure it in meters because c is constant (apart from that it is a more natural way of measuring it than in seconds), but that does not mean that stationary objects are moving at the speed of light, it I could do the same with any other constant.

## At what condition does Lorentz transformations become Galilean transformation?

Galilean transformation. Mathematically, Lorentz transformation approaches to Galilean transformation as the speed between the observers approaches to zero. True, when the speed approaches to zero, but we deal wit finite speeds in physics.
