moving faster than light.
He was so fast that everything else move slower than him. Even the camera flash are only able to capture his face as a blur. In a relativistic sense. For a body that move faster or aprroaching speed of light that body will actually perceive everything else slow down and to a point where things stood still for that body.
This serve as an intro before we study time dillation topics where time dillation phenomenon of someone perceiving one second clock movement tick as slower when he or she is travelling at high speed . WhileThe second clock movement is always view as one normal second for an observer on the ground who is at rest (not moving).
Clark was so fast that one second for us means several second for him, enough for him to push the mugging man and save Lois and just let Jimmy capture him with the camera. For Clark to experience expanded time is the very definition of Time Dillation (movement between seconds is expanded) where dillation means To resize something.
In general English it means to make larger.
But in physics Mathematics it means to make larger or smaller.
Just to refresh the inertial frame of reference in this case is
1.Lois (falling at constant speed)
2.Jimmy (not moving)
3.Mugger (not moving)
4.The car that almost hit Lois (constant speed)
5.Clark Kent (aprroaches the speed of light) c= speed of light
Why Clark speed cannot be more than speed of light, because the time dillation formula will not work for speed more than c. Another reason is that special relativty concept is invalid For movement more than c as we need general relativity to explain it. Regardless Clark speed is well close to the speed of light as he has several seconds window to save the day.
Postulate: Speed of light is the same for Clark and everyone else.
Law of Physics is the same for all observer,.
