Is it possible for photons to display in the center of room?

    Is it possible for photons to center themselves in mid-air in the center of a room, multiplying and change directions while still being somewhat centered in the room? I have tried looking this up in Google, but all I got were articles which I did not have enough time to read. If this is the wrong place to put this thread, please excuse my fault.

    Thank you for all whom reply.

    A photon can be anywhere, (arguably), but it can't replicate, it's a fundamental particle.
    When considered as particle (as opposed to a wave), it's trajectory can be altered by strong gravitional fields.

    What would happen if someone somehow is able to replicate the photon?

    I'm not sure what your concept of replication is.
    A photon is a small 'quanta' of electromagnetic energy, it is what it is.
    Photons cannot generate more photons if that what you mean.

    Ohhh okay, I see. Thank you for making it clear! :D

    Closest to what you are talking about could be a device called a photomultiplier.
    It can absorb a few photons and then use this to trigger a process which creates several more photons , but the new photons are being created from an external energy supply to the device.

    Not without some substantial help from various electro-optic devices.

    A photon cannot "center itself" any where because it cannot stand still. A photon is always travelling at "c", the speed of light.

    Er.. wait, hang on. A "photomultipler", contrary to its name, is not a device that makes more photons!

    It is a vacuum tube in which a single photon triggers an electron cascade via secondary emission. This electron cascade then is recorded as an electrical signal. It is essential to make the device sensitive down to a level of single photons. It doesn't generate more photons.

    Coming back to the original question, I'm surprised that some people actually understood what was being asked. I read it three times, and I still don't understand what this "center themselves" means and the rest of the post.

    I think no matter the interpretation of the question, it is safe to say the answer is "no".

    Oh OK, I thought it acted more or less directly as an amplifier of low level light and some other device converted the result into an electrical signal.

    Unfortunately there is trend to hurry with answer before trying to clarify what the question is. :smile:
    It's manifested in general but sometimes even on this forum.

    If photons could somehow center themselves in the middle of a room you wouldn't be able to see them because they wouldn't be travelling to your eye.
