If the speed gets close to the speed of light the mass grows to infinity

Explanation:

If the body is in movement at speed close to the speed of light its mass is equal to:

#m=m_0/sqrt(1-v^2/c^2)#

where:

#m_0# is the mass when the body is not moving
#v# is the body's velocity
#c# is the speed of light

From this formula we can see that as the velocity gets closer to #c#, the denominator gets closer to #0# so the mass gets bigger and goes to infinity.
