    It is unreal how far we can see now….or percept…however it is done.. We seen how much a light-second is. It revolves the earth like 7 times or something. A light year is pretty much imaginable how far it is. Then, we know how big a number a million is…. Then a billion is 1000 times the million. We can see hundreds of billions of light years away. This is really under-rated. Crazy.

    "…and the amount that they are measuring is nowhere near what we are observing.", what does that even mean? unless you mean to say "the amount that the Big Bang theory predicts is nowhere near what we are observing.

    Pro Tip: Those Ultra High Energy Cosmic Rays are the ones you want to fly through unshielded if you want super powers. So I've heard…from a friend…whose definitely never done it.

    but wouldn't that mean the gravity of earth is also caused by dark matter or affected from it, and if so surely we have miscalculated the gravitational effect from regular matter,

    it is not missing,,, it has disappeared into the myriads of black holes since, well, the beginning.
    and the universe is not expanding- we forgot to account for the incoming light hitting the heliosphere and being "red-shifted"

    Imagine the lights of the lasers still travel far altought the ships have long gone. A war so big that the space armadas spread over lightyears. The debri left over now eroded by billions of years. A war brought on by a merging of the first galaxys. A war that would devestate the first life.

    And that is the light that we still see today, lightyears away. What we call the himiko cloud

    The background music is very distracting… bordering on annoying. I would like to "like" the video, but I don't press the like button on videos with annoying features. But I really like the rest of it.
