I don't know whether the question is asked before on not on this website as I can't found it anywhere so I have to ask.
What will happen if a place a long stick with a length of a light year. Rather othe dimensions not matter just the sri k is a s long as a light year. Now I have placed a switch just in one end of the stick 1 cm apart. And the other end is on earth. Now my question is that what will happen if I push that stick and send a beam of light simultaneously toward thar stick who will win. The stick or the beam.
I know the light will win but can you explain the phenomenon.

Are you including reaction time? Or you think you are quicker than Bruce Lee? Then, of course, how fast will you be moving the stick? – Jun 30 '19 at 07:55

Let's talk about a hypothetical condition where I can do it with a force which is equivalent to move the stick with the speed of light C – Ankit Kumar Jun 30 '19 at 07:59

Then light still beats the stick because of your reaction time, or are you about to make an assumption for that as well? – Jun 30 '19 at 08:02

Ahh can you explain more deeply what is a reaction time – Ankit Kumar Jun 30 '19 at 08:09

I'll let you do some research for that... – Jun 30 '19 at 08:11

@Solarmike Apart from reaction time, the stick isn't infinitely rigid, and it can't transmit a pulse faster than the speed of sound in whatever material the stick's made from. See the linked duplicate suggestion. – PM 2Ring Jun 30 '19 at 08:33

@PM2Ring the OP did not make that assumption about rigidity... Ahh, shame. – Jun 30 '19 at 08:44

@SolarMike Questions about infinitely rigid poles, like questions about spaceships traveling at lightspeed, are off-topic due to being about non-mainstream physics. ;) – PM 2Ring Jun 30 '19 at 08:48
