  1. Nothing can travel faster than light, so it's impossible for "information" to travel from one place to another instantaniously. But relativity and quantum mechanics are not consistent at small scales, from what I understand. At small scales, at about the Planck length, relativity breaks down and quantum physics takes its place completely. I am not really good with physics yet also, so you maybe ignore my comments completely.

  2. Is there an Absolute Highest Temperature opposite to Absolute Zero?

    This depends on what one thinks the 'Theory of Everything' looks like. If there is a steadily increasing ladder of more and more massive particles ad infinitum, then as Physicist Hagedorn showed in the late 1960's, the maximum achievable physical temperature in the universe may be as low as a few trillion degrees. What happens is that as the particle thermal energy increases, the energy goes into creating progressively more massive particles with low kinetic energy. Eventually, no matter how much energy you 'feed' into such a system, all that happens is that you generate more massive particles with a lower kinetic ( thermal) energy. In essence, this pair production of massive particles acts like a 'coolant' which regulates the physical temperature at a finite, and perhaps surprisingly low temperature.

     

    If the so-called Standard Model is correct, then quarks are fundamental and do not sub-divide into still more massive particles. The thermal energy is then free to increase practically without limit until you eventually end up creating 'quantum black holes'. This happens at a temperature of 10^32 Kelvin; that's 1 followed by 32 zeros! Once you produce quantum black holes, you have reached what many theoreticians believe is the end of the road for physics as we know it. Here, spacetime itself dissolves into a witches brew of quantum worm holes, black holes, multi-dimensional super strings and twistors. Most theories of the early universe give this temperature as a true limiting temperature for physics in the universe.

     

    This is what I find about the absolute highest temperature. I don't know if it's true or not though.......

    Now I know that the reader will have very serious reservations about taking this on board but before they reject this assertion they should check out the following calculations. For an object to escape the Earth’s gravitational embrace it must travel at a speed of at least 6.94 miles per second. Now the Sun’s mass has been calculated at 333,400 times that of the Earth’s. Ergo for an object to leave the Sun behind it must travel at a speed of 6.94 miles per second multiplied by 333,400. This gives us a velocity of 2,313,796 miles per second or, to put it another way, a speed that is very nearly twelve and half times the speed of light. Present theory dictates that physical entities cannot travel at such velocities. We are also aware that particles: e.g. the solar wind (calculated at a velocity of 400 miles a second) and coronal mass ejections (calculated at a speed of 600 miles a second) are streaming outward from the sun all the time. So just what, exactly, is going on here?

     

    The escape velocity is not entirely proportiional to it's mass.

    The equation for escape velocity is:

    v=sqrt(2GM/R), where v equals velocity, G equals gravitational constant, M equals mass, and R is the radius.

    So if we calculate the escape velocity of the sun, we will get

    sqrt(3.81*10^11 meter/second)

    Which is equal to about 600 km per second.

    So the escape velocity is not 12 times of the speed of light.

  4. I don't think we can determine the absolute high temperature because as the temperature goes higher, the faster the particles go, but the faster it goes, the heavier it gets, and it needs more energy to make it go faster. And once that temperature is reached, it became heavier again and slows down. So we can't determine the absolute high temperature because relative effects keeps it from ever going to the speed of light. Just a thought though, nothing more......
