    I M GONNA PUT THIS AS SIMPLY AS POSSIBLE:

    TIME TRAVEL IS SO STUPID AND MAKES ME ANGRY I DON'T EVEN CARE WHAT YOU SAY

    had an episode on time travel Thursday.

    I think Discovery has a show on time travel as well.

    I don't see how it would be possible to travel either backwards or forwards in time unless you could hitch a ride on some particle that travels through time....maybe some unknown particle that was created when the universe was made and that travels back and forth in time.

    Of course ..if parallel universes exist..another Discovery channel show if I recall correctly....maybe it's still WW1 in the other universe and you could kill Hitler during WW1..shoot him in his trench in France and he would never become the Fuhrer and you could spare that universe his future actions.

    That might help that other universe but wouldn't have affected events in ours.

    I was curious about the speed of light once, so spent a week studying it thoroughly for no reason. I was a lonely child...

    My young mind figured it's impossible for something with mass to travel at the speed of light. In order to do so, every piece of matter would have to be transformed to energy, including the travelling matter itself, rendering the whole thing pointless. Hence the requirement for things like cool warp jump stuff. One cannot accelerate to and past the speed of light, as we do with our current methods of transport. However, to travel at, say 1,000,000 times the speed of light costs only the same amount of energy to travel 1/1,000,000th of the speed of light. So, if we can make that jump rather than accelerate to it, we would be travelling faster than the speed of light.

    I forgot how to relate that to time travel. If I arrive at a place a week before the light from where I started does, have I travelled forward in time?

    Seriousness aside, when I'm 79, I finally figure out and build a time machine. I will use it to travel back to when I was 17 and I gave it to myself. I then travelled the world. Unfortunately, I am the start of this paradox, so I have to wait till I'm 79 before I can change everything.

    Time is a myth, like Christopher Columbus being important or condoms.

    It is impossible to prove the speed of light is the max speed, or even that all light moves at the same speed. Text books say that light from the sun moves that speed after vibrating in the sun's core until it reaches a speed high enough to break free. so wouldnt a bigger, denser star release faster light?

    I completely disagree. There is absolutely no validity behind the above arguments and the solution is entirely irrelevant. As you can see clearly it contradicts ideas put forward by both Bose and Einstein:

    Bose–Einstein condensate - Wikipedia, the free encyclopedia

    Not to mention that it even fails to obey the fundamental time dependent Schrodinger equation. (See Schrödinger equation - Wikipedia, the free encyclopedia for more details)

    You can't argue with physical reality. Time travel is very possible. In fact, we're all doing it right now.

    I don't see how it would be possible to travel either backwards or forwards in time unless you could hitch a ride on some particle that travels through time....maybe some unknown particle that was created when the universe was made and that travels back and forth in time.
    You can travel into the future at a faster rate than one normally does. You do this by moving at a velocity close to that of light. This slows down time in your frame whilst others continue to move through time at the same rate. When you stop moving to look around after 10 years of travelling, your body will only be 10 years older, but everyone around you will be much older - maybe even long dead from old age, depending on your exact speed.
    My young mind figured it's impossible for something with mass to travel at the speed of light. In order to do so, every piece of matter would have to be transformed to energy, including the travelling matter itself, rendering the whole thing pointless. Hence the requirement for things like cool warp jump stuff. One cannot accelerate to and past the speed of light, as we do with our current methods of transport. However, to travel at, say 1,000,000 times the speed of light costs only the same amount of energy to travel 1/1,000,000th of the speed of light. So, if we can make that jump rather than accelerate to it, we would be travelling faster than the speed of light.
    The reason why an object with mass cannot travel at the speed of light is purely down to the Lorentz factor. Lorentz factor - Wikipedia, the free encyclopedia

    As velocity tends to the speed of light, the mass tends to infinity and hence the energy required tends towards infinity. At the speed of light, the energy would be infinite and thus it's impossible.


    And actually your latter argument is patently false. If v were significantly greater than c, the Lorentz factor would enter the imaginary realm. Thus such a scenario would be physically meaningless.

    It is impossible to prove the speed of light is the max speed, or even that all light moves at the same speed. Text books say that light from the sun moves that speed after vibrating in the sun's core until it reaches a speed high enough to break free. so wouldnt a bigger, denser star release faster light?
    Travelling faster than the speed of light violates all relevant equations. Thus it is impossible insofar as we know. There is however a possibility that the equations, although very powerful and accurate, are not always correct in every situation.

    And no, bigger stars don't release faster light. They release light with a higher amount of energy, which means the photons have a higher frequency and thus a different emission spectrum. Photons always travel at the speed of light, because they are massless.

    Hey, I'm just impressed I managed to get one bit right without actually knowing anything. Whilst at the age of 11. Booyah!

    This is absolutely inexcusable. At the age of 11 I had already completed my PhD in particle physics and written a thesis on the validity of the Gross-Pitaevskii equation.

    Educational standards truly are slipping.

    That may be so, but my manipulation of vector calculus is still vastly superior.

    My manipulation of the clitoris is vastly superior.

    Sorry, I am not familiar with "the clitoris". What empirical or mathematical meaning does it invoke, and which great physicist or mathematician discovered it?
