God is mad

I guess

girls and boys who are good know that Proca equation is used for spin 1
particles

I am not saying Proca equation is right

Lagrangian function for this kind of particle has 2 parts - the first
part has a minus sign and the second part has a plus sign

girls and boys who are good can think about - use certain numbers for
tachyons - Lagrangian function and Proca equation

use certain number for mass - try - imaginary - real - for mass of
tachyon - see how parts act
for Proca equation and Lagrangian function - like what sign does second
part of Lagrangian function have

equations are good for photon with mass associated with tachyons

all spin one particles are tachyons
