    Never ever have I watched such a beautiful engaging Ted talk. Honestly it was the best talk ever. The way he presented everything was even more beautiful. Even I believe in the multiverse theory but then it makes us question everything we already know . It puts to test all our beliefs The universe is truly a mystery and so are we.

    This is really freaky. That would mean we cant exist outside the bounds of our own universe, since we are made like a programm that works only on that particular machine. It would mean that everything is bound to its own universe and simply cant exist anywhere else. This is kinda depressing, there goes the idea of traveling to one lol.

      nanotech2080 Yeah for sure, it's mind boggling to think about. Not to mention life as we know it is just that as we know it. We have barley even traveled off of our tiny little rock in our tiny speck of a solar system. It might turn out that the "Goldilocks zone" really only applies to our type of life that specifically evolved to adapt to our specific environment. There could be gas based life, non carbon based life, life in the center of frozen planets kept warm by the planets molten core. Life could be a inevitability caused by energy, meaning sun's could even be "alive" just not in a way we currently comprehend. Now this sounds like crazy science fiction and it may be, but the universe just gets stranger the more we discover, and we keep adding pages to the book of science.

      I think they will believe that these things existed, as yes it's "ancient" data, but this data will always be conceived as true and as today's scientists grow old and die, they will prolly tell their next generation that these proofs are infact true and correct, and the reason behind and the way we found it out, and maybe who knows, if we were at today's tech and knowledge a few million or even billion years ago, who knows what we could see, maybe even the edge of the universe? We could maybe even graph the entire universe and properly study it, and maybe then we can get a theory of everything, but sadly it's never gonna happen

    It’s easy to see how the universe is expanding at an increasing rate. We are surrounded by dark matter even here on earth quantum physics proves it. In fact; what we perceive as solid is far from it.
    Between every atom there is space. Inside of every atom the subatomic protons, neutrons, and elections have space between them. Even smaller particles called quarks and leptons have space between them. So considering the density of subatomic particles being suspended then the infinite amount of dark mater is what is pushing the universe apart.

    it's sad to know that future astronomers will forget our discovery and knowledge about other galaxies and how big and old our universe is , or dark matter, string theory etc, just like we ignore cave men's drawings of gods and aliens visiting.

      @@joker3053 I don't know man, cave Mens drawings were drawings whereas there is recorded evidence of this eras findings and even if they cant understand our languages there are saved mathematics and codes we have created that are binary that they should understand. Plus some people belive the Carmen's drawing and are extremely interested in them and research them so what's to say future people wouldn't do the same and unlike cavemen there is much more evidence of our eras inteligence, not to say cavemen weren't also intelligent as they did set the ball rolling so to speak

    "Which means that we are living through a remarkably privileged era. When certain deep truths about the cosmos are still within reach of the human spirit of exploration. It appears that it may not always be that way." This made me so sad, one day these records will most likely be lost, and that hurts my heart. We are probably meaningless in terms of a multiverse, which I think is ok, we just have to accept our role.

    I’ve played with the idea of a multiverse and the idea that if there are infinite universes then there must exist universes identical to each other, and while this is possible, there is also the possibility of infinite universes that aren’t like each other one bit. Let’s look at something as simple as our natural numbers. They go on infinitely in a positive and negative direction however while there are an infinite set of numbers not one value repeats. The odds of finding a number identical to the value of 1 are 0 and that goes for any value.
    And as far as dark energy goes; with our current laws of physics we can’t create nor destroy energy however it can be manipulated. Could there be a way to someday manipulate dark energy and would doing so damage or better the universe we live in?
