WHAT WOULD HAPPEN IF A BODY MOVED WITH SPEED OF LIGHT?

IF A BODY MOVES THE SPEED OF LIGHT, LIGHT CANNOT REACH IT FROM ITS BACKSIDE.
LIGHT CAN HIT IT FROM FRONTSIDE BUT THE BODY WILL MOVE WITH THE REFLECTED LIGHT ITSELF.
FROM SIDEWAYS THERE IS NO WAY LIGHT CAN HIT IT.
SIMPLY WE CANNOT DETECT IT.

AGAIN FROM EINSTEINS LAW
ITS LENGTH WILL DECREASE WHICH WILL CONTRIBUTE IN DECREASE IN VOLUME.
MASS WILL INCREASE WHICH WILL RESULT IN INCREASE IN DENSITY.

FROM MASS ENERGY CONVERSION LAW THE REFLECTED LIGHT THAT THE BODY MOVES WITH MAY FURTHER INCREASE ITS MASS .

ULTIMATELY IT MAY TURN INTO A BLACK HOLE.

SO TO SAY " THE BODY IS MOVING WITH VELOCITY OF LIGHT" IS ENOUGH TO DESCRIBE A BLACK HOLE.
????????????????? I MEAN, IT SHOULD BE........

First, matter cannot move at the speed of light. The energy necessary to accelerate a single hydrogen atom to the speed of light in a vacuum is infinite.

Second, a "black hole" describes a region of space that is so warped by gravity that light cannot escape it. It has nothing to do with moving at the speed of light.

I read that if the Earth were crushed into a black hole, the event horizon would only be about 1 centimeter. Cosmic rays on the order of 10-19 power electron volts have been observed, and they do not produce gratitational radiation when they strike the Earth. It is physically impossible to accelerate at cosmic ray until it is a black hole, because the required particle acceleration would have to be done inside a supermassive black hole for the required energy.
