tachyon เป็นอนุภาคอนุอตอมทางทฤษฎี(hypothetical subatomic particle)เร็วกว่าแสง
Arnold Sommerfeld เสนอเป็นคนแรก
สัมพัทธภาพเฉพาะ m = m0/sqr(1-(v/c)^2) เมื่อ v>c --> m0 ควรเป็นจำนวนจินตภาพ
rest mass m must be imaginary, as a pure imaginary number divided by another pure imaginary number is a real number

Because a tachyon moves faster than the speed of light, we cannot see it approaching. After a tachyon has passed nearby, we would be able to see two images of it, appearing and departing in opposite directions. The black line is the shock wave of Cherenkov radiation, shown only in one moment of time. This double image effect is most prominent for an observer located directly in the path of a superluminal object (in this example a sphere, shown in grey). The right hand bluish shape is the image formed by the blue-doppler shifted light arriving at the observer—who is located at the apex of the black Cherenkov lines—from the sphere as it approaches. The left-hand reddish image is formed from redshifted light that leaves the sphere after it passes the observer. Because the object arrives before the light, the observer sees nothing until the sphere starts to pass the observer, after which the image-as-seen-by-the-observer splits into two—one of the arriving sphere (to the right) and one of the departing sphere (to the left).
