Physicists: Self righteous morons who claim that it's impossible to build a lightsaber. According to these unbelievable guys light can't form a short blade but any kind of light will keep travelling unless an obstacle absorbs or reflect the energy. Further more they claim that a simple kyber crystal is not enough to power on a lightsaber, complex optoelectronics and batteries should be used ....... and as if all that was not enough they also claim that clashing lightsaber blades is impossible .... the beams would just pass straight through each other rendering a duel impossible.
They lack the mental capacity to understand that THE FORCE can easily overcome these obstacles. They don't even believe that THE FORCE exists ...... instead they believe that matter consists of elementary particles following either the Fermi-Dirac or the Maxwell–Boltzmann statistics and interacting in a manner precisely described by mathematical laws.
I'll send my apprentice to teach them the lightsaber and the technology behind it
But before I'll do that ..... I'll deal with the greater evil @Stormbringer
