Dr Alex Baker from the University of Warwick thinks it may be possible to create a real lightsaber using plasma, the fourth state of matter. He warns of its dangerous potential and cautions against public accessibility.
Plasma would be the key element in a lightsaber, ionizing gas from the air to form the blade. This ionized gas carries an electrical charge allowing it to cut through steel at high temperatures.
Attempts by YouTubers like Russia's Alex Burkan have been made to create plasma lightsabers, but challenges include limited blade appearance and duration. Canada's James Hobson's version required a backpack for power.
'People have made devices that make a straight jet of plasma that eventually cools and deionizes back to gas,' revealing limitations on the blade length due to the plasma's behavior.
