Answer:

No. On the contrary it appears heavy.

Explanation:

It is a case of quantum mechanics.

Whenever speed of an object is comparable to the speed of light the laws of classical mechanics are no longer valid with rest mass #m_@#in the equations.
For such cases the

#E_(t otal)=gamma. m_@ c^2#
where Lorentz factor #gamma-=1/sqrt(1 - v^2/c^2)#

Lorentz factor #gamma=1# only for small values of velocity when # v^2/c^2# in the denominator is small and can be ignored.

Observe what happens to the value of Lorentz factor when #v=c#. It is a singularity.
