# Relativistic effect of light photons

I recently studied Relativistic effect and I have few doubts. Please clarify

Dual nature of light

Light has dual nature. So let us now assume that light is a particle and consists of light photons. Now, since light photons are travelling at the speed of light due to DIMENSIONAL CONTRACTION it would be shrank it the size of a POINT with ground frame. Meaning it should have originally been INFINITELY LARGE in size now if it is infinitely large than wouldn't the DRAG FORCE on it be very large. Therefore to overcome drag force shouldn't the photon travel at speeds greater than SPEED OF LIGHT.

AND IS THAT EVEN POSSIBLE ?

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

• Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
• Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
• Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.

my first thought: WHAT THE HECK?! WHAT ARE YOU EVEN SAYING?!
On second thoughts, it's better to talk abot my own opinion about photons:
FACT: photons have no mass. photons are imagined to have no volume, like other basic particles.

from what you're saying, I guess you mean a photon has more than 3 dimensions so it is shrunk to a dot by 'dimensional contraction'. But do photons have more than 3 space dimensions?
second problem:you say how larger size results in larger drag force. it you mean infinitely DENSE or HEAVY, nope! photons have no mass! and if you mean BIGGER, let me assure you: as long as this universe only has 3 dimensions, photon will always remain infinitely small!

one thing I did notice: if photons do have over 3 dimensions and is put in a world of higher dimensions,it may travel faster than light in 3 dimensions.
BUT IN OUR UNIVERSE, I ASSURE YOU, NOT A SINGLE THING GOES FASTER THAN LIGHT, NOT EVEN LIGHT ITSELF!

I do know that photon doesn't have mass. But consider a pulley system with ideal string. Even though it has no mass, force like TENSION can act on it similarly I am thinking in this case but I don't whether it is applicable ?

You said that all the basic particles have no volum , does it mean that electrons , protons ,and neutrons all have zero volum . But how is that ?

- 2 months, 1 week ago

Well, theoretically they have no volume, or at least it is small enough to be ignored, but that doesn’t mean it definitely has no volume. Again, zero volume simply works as a hypothesis for many theories!

and if dimensional contraction means a twist or wave in spacetime, light travels through it in a bended path.

- 2 months, 3 weeks ago

Dimensional contraction means like if objects are travelling with high velocities then in a stationary frame the object would have shrunk in size wrt stationary observer.

Oh I see :) well if you shrink something with no volume you get no volume don’t you?

- 2 months, 3 weeks ago

And if you undo it, you get the same, right?

- 2 months, 3 weeks ago

I guess you are right, well anyway thank you

- 2 months, 3 weeks ago

You’re welcome :)

Well since you are online, tell me something about China ^^

- 2 months, 3 weeks ago

China has area of about 9600000 square kilometres, its population over 1.3 billion (perhaps now over 1.4 billion). The tallest mountain in the world, Mt Everest, lies in the southwest of China.

Lol, just kidding , don't take it seriously :)

Too bad I saw this after typing :D

Never mind anyway XD .
