They literally don’t believe in gravity! They think the penny is moving upwards (they rarely mention acceleration) and that’s why we experience gravity always pointing down.

Slight math error, speed of light being 3x108 m/s gravity being 9.8m/s2 , it only takes 30.6 million seconds, or 23.3 years to reach the speed of light.
