Developed as a means of sidestepping the impossible production challenge of landing a ship every time the characters went ashore in Star Trek the transporter is a marvel of impossible science and utterly fantastic energies.

The show’s lore the transport converts the target’s, usually a person, matter into energy, beams it to a distant location, then reconverts that energy back into matter precisely recreating the person at the new location.

Let’s sidestep the ‘Ship of Theseus’ question if the reconstituted person is actually the same person or not for another essay and focus on the physics of this process.

Einstein revolutionized the world with his understanding that energy and matter were equivalents as set forth in the world’s most famous equation E=MC^2. The energy value of a mass is equal to that mass multiplied by the speed of light squared.

Let’s put a 50-kilogram (110 lbs.) person on the transporter and set them down.

50 kg converted entirely to energy becomes 4,500,000,000,000 megajoules. Such a number is simply beyond human comprehension. It is the equivalent 71 thousand Hiroshima bombs delivered instantaneously as a beam to a distant location. If the transporter chief held a grudge against the person on the planet that had sold him a crummy watch, he could deliver 71 thousand Hiroshimas.

There is a reason why in my Space Opera role playing games when I have introduced a transporter like device it has never ever been of the variety that directly converted matter to energy and back again. Star Trek would have been far better served if someone had decided early on that the transport simply created a gate between places and saved us from both bad technobabble solutions to problems (we’ll just put the doctor in and reconstitute her from an early pattern) and not introduce a weapon of such scale and destruction.
