How fast would you need to be to dodge light that’s 1cm away 10 feet away and 20 feet away

Answer 1

983,571,056 feet per second = the speed of light

=299,792,458 meters per second

=29,979,245,800 cm per second = almost 30 billion cm/sec

10 feet = 120 inches = 120(2.54) cm = 304.80 cm = 3.048 m/s

you'd need to move about 100 million meters per second

299,792,458/3.048 m/s= about 98,357,106 meters per second

20 feet = 609.6 cm = 6.096 m/s

you'd need to move about 50 million meters per second

299,792,458/6.096 m/s = about 49,178,553 meters per second

you'd need to move about 1/3 the speed of light at 10 feet

about 1/6 the speed of light at 20 feet

You can't move that fast. If you somehow did, biological problems would probably be fatal.
