just talked to my physics prof about this actually. i guess to move at c you cant have any mass. if you look at the problem graphicaly youll see that the energy needed to overcome the object's inirtia (i think maby this is total bs) asymptotes so you never actually reach c while still having mass.
all we need to do is "hide" our mass and we can move this fast.
would tachyons be invisable? because light couldnt catch up w/ em to reflect off of them? thats assuming there a particle. .....guess they could just be waves but wouldnt they have to be quantized somehow? ehh maby im talken out my ass. should take that second yr of physics i guess.
Just an odd comment about the tachyons being invisible:
What do you mean by "invisible"
Individual atoms cannot be "seen" with visible light - the wavelength of light limits the possible resolution. But, we can image atoms using other techniques. Electron microscopes exist because of the limitations upon visible light microscopes.
A scanning electron microscope (SEM) works by shooting a focused beam of electrons at a surface and creating an image based on the reflection of those electrons. There is also a transmitting electron microscope (TEM) where the electrons are passed through a very thin sample - the image is created by detectors detecting where the electrons strike after passing through. Focusing is nearly analogous to light microscopes, but the electrons are focused by magnetic fields rather than lenses. And, rather than your eye being the receptor, the electron microscope creates that image for you and displays it on a monitor (or a pretty photograph that it can print out.) I still have a pile of old photos from back in the day when we got to play with an SEM at college.
