Why do we need relativistic wave equation?
In physics, specifically relativistic quantum mechanics (RQM) and its applications to particle physics, relativistic wave equations predict the behavior of particles at high energies and velocities comparable to the speed of light. one of the postulates of quantum mechanics.
Why is relativity so important?
The theory explains the behavior of objects in space and time, and it can be used to predict everything from the existence of black holes, to light bending due to gravity, to the behavior of the planet Mercury in its orbit. The implications of Einstein’s most famous theory are profound.
Is Einstein’s theory of gravity compatible with quantum mechanics?
Copyright Norma Sanchez. Yet although Einstein’s theory has been watertight enough to hold up to even the latest astronomical observations, it appears to be completely incompatible with quantum mechanics. For physicists, this calls for an even deeper generalisation, which has been pre-emptively given the name ‘quantum gravity’.
Why has quantum physics been so successful?
In the subsequent decades, the resulting field of quantum mechanics resolved many questions which classical physics didn’t have the means to answer. Ultimately, the success of the theory stemmed from the fact that quantum theory is a ‘generalised’ theory, of which classical physics is just one specialised branch.
Is there such a thing as quantum gravity?
For physicists, this calls for an even deeper generalisation, which has been pre-emptively given the name ‘quantum gravity’. In her research, Dr Sanchez aims to realise such a theory, in which both quantum mechanics and general relativity are particular branches which are contained on their appropriate scales.
Why does Dr Sanchez use Einstein’s theory of general relativity?
Because of this, Dr Sanchez uses it as a standard theory, which emerges from her own theories in particular situations. Einstein’s theory of general relativity solved many, but not all, issues relating to gravity.
