• I mean really….

Let’s see 80 kilo human being (rest mass) accelerates to c in less than… call it 40 kilometers

v =  a*t

42 seconds to reach max velocity

300,000,000 m/s = a * 42s

a = 1,742,000 m/s2

In spite of the fact that his entire mass is now crushed into a glowing hot, molecule thin layer of plasma, he still has his 80 kilo mass.  Well sort of…

Just a reference that I found…
The relativistic kinetic energy of a 1 kg mass impacting at a velocity of 0.9999999999999999999999999999999999999 c (37 nines)= 2.01×10^35 J. This is about 1,000 times the total gravitational binding energy of the Earth – 2.24×10^32 J

He hits the Earth at c and instantly his mass (the mass equal to the galaxy) is converted to energy and within 8 seconds, everything within 98 million miles is vaporized… including our sun.  Of course, there will be a spectacular nebula forming, once everything cools down enough to be transparent to most of the visible spectrum.

Probably nothing left but a quark-gluon plasma for a good hundred thousand years.
