It is impossible for objects with mass to reach light speed. The energy necessary would be infinite. Even in accelerators like CERN it is only small particles (protons) that are accelerated to almost light speed. They use as much energy as a whole city just for a few protons.

according to the laws of physics, it's a physical impossibility for an object with mass to reach the speed of light.
i don't think it would be ever possible to accelerate an object so that it would have the same velocity as light. although this is the case, some things like high-speed electrons do come close to the speed of light, but doesn't reach it.

Light-speed is 186,000 miles per second in a vacuum (like space). I do not think we have reached this speed with a human even in those secret government experiments (just a guess). But some day we will. There is no boundary that the human mind can not surpass.

If e = mc^2 is true, then all the energy of an object has to be converted to kinetic energy to reach this speed. Even your mass has to be converted to kinetic energy. You may be going the speed of light, but there's no more of you left.

If you shook ahnds with an identicle person to yourself made of antimatter then you would both disappear into a big puff of energy - mostly light and heat which would certainly travel at the speed of light.
But - As yet there is no reversing process!

Possible yes, light that you see is going the speed of light always. It's also thought that it's possible to go "Faster Than Light" or FTL. There are many theories and studies on this very topic. To start off you can read this: http://math.ucr.edu/home/baez/physics/Relativity/SpeedOfLight/FTL.html

No...not for any physical mass. Energy can travel at light speed (hence the name), but it is impossible for an object with mass to obtain....at least not yet!

i am not sure to answer this question but i can still say that i am sure we will be able find some alternative for this also.
on the other side i have been wondering over this question that if we assume the velocity of light we can reach our near future and past.

No. the only reason photons can attain the cost of light is by technique of the fact the have no mass. to be certain that a mass too attain the cost of light you will possibly wish an limitless quantity of potential appearing on an merchandise for an limitless quantity of time.

Accelerators can approach this speed, yes, but to sustain it for travel is not yet possible.
