      exactly, the world has no closure. It is forever changing, but just out of the realm of our perception. Our mass suffering from humanity is mostly extracted by this need for closure and to feel things make sense. It's not that things are not interconnected but we must take into the account we only can observe a sliver of what is truly occurring in this reality. We may never know when the times comes that we are exposed to something within the moment that could explain the depth of this reality to you, but if your always looking for models and closure we may never be exposed to this moment. “You must be shapeless, formless, like water.

    Consider every observer as a reality sampler and reality generator, with a theoretical maximum sampling frequency.
    In order to move, observers have to sacrifice time slots for which no reality updates occur.
    Thus time will progress in different speed for the observers depending on their movement.
    And the maximum theoretical sampling frequency would explain the constant speed of light - it's the clock frequency of the universe

    you are incorrect to think that time is relative (at least according to einstein) - more like time is relative as light is - light is essentially the constant of time (at least for any given frame of reference) but einstein is saying that light is not relative right? since it is consistent to any speed, position, frame of reference or relationship between anything that is not singular with anything else
    i think that light is itself the medium (the ether) and why it appears with some odd properties

    Never could understand how the speed of light could be the same for everyone.
    What if you are traveling in a space station away from earth at 51% C and launch a ship from it going the same direction at 51% C. Wouldnt that ship break the speed of light relative to earth?

      Relativity tells us that we can't aggregate speeds like that.

      Space is infinite because of inflation and the acceleration of dark energy rn. The universe is cyclic and there are photons that will travel into infinity without hitting anything, after the heat death of the universe at the very end those photons coalesce and travel into the next aeon via a Big Bang and we can observe the energy from it via gravitational waves and feedback, search roger penrose cyclic universe, man is 89 and spot on

    Didn't like what he said about agreeing on what time it is. Yes, it's always 5 o'clock somewhere. But you could get everyone to agree that now is now. Just like here is here. And if you point to a distant object and say there is there, everyone would agree there is there and not here. It's just less obvious that there is also then, not now, from here.

    So cool how at the sametime many teams of humans totally unconnected can invent same things or solve the same problems.
    Newton understood this very well knew when to move to the next problem ready to be solved. The super athiest like Hawkins will beat heads against the wall on unlovable problems but never creative enough to spot this "it factor " of merging readiness.

  • @leeberry3708
    @leeberry3708 3 года назад

    Could the temperature of space effect the speed of light? Light photons are warm in nature correct? If that is the case then would the temp of space slow the light down and actually stretch the light into different spectrums the farther it travels while the light was maintaining its speed. And not an expanding universe but the temp of the universe itself. So will a cold universe slow light down and stretch it over time space? I'm asking because the expanding universe theory isn't quite making sense although I understand what's being said.
