    *The case of mistaken identity* The LIGO (Laser Interferometer Gravitational-Wave Observatory) project when analyzed is actually a seismic device which measures vibration in the Sub atomic scale. The reported chirp signal detection that is declared to be gravitational wave could be a signal related to quantum noise. What is quantum noise? Quantum noise may be observed in any system where conventional sources of noise (industrial noise, vibrations, fluctuations of voltage in the electric power supply, thermal noise due to Brownian motion, etc.) are suppressed and yet random vibration can still be detected. This phenomenon is considered to be part of the ‘quantum foam’ that is ever present, which cannot be filtered out. This being a reality of the physical world, it becomes plausible that the chirp (gravitational waves) is actually related the quantum noise phenomenon and not with a cosmic event, such as black holes a neutron stars.

    if you look at the totality of everything that had to go right for us even to BE here, we're NOT. That's why it's so quiet out there - we're an incredibly unlikey accident, and probably not repeated. Given all the things that could conceivably destroy us, earthly or not, we're going to have to work a helluva lot harder to stay in existence than we currently are....or else.

    I published my book about the universe, "The Great Knowledge about the Everythingness". I was able to crack most secrets of the universe. It explains exactly why there is something rather than nothing. This solution makes possible to understand the universe even better. It also proves that the perpetual motion machine is impossible. Because scientifically speaking that device is a creator. That device will be classified as a creator in the near future. You cannot build a god.

    (5:15) This balls-in-a-box thought experiment is not a good analogy to people's birth ranks. Time is of the essence... A better analogy would be two boxes starting out empty, then being filled simultaneously at consecutive rounds. One box will stop being filled at 10 balls, the other at 1000. After the first round both boxes each contain a single ball; after 5 rounds both contain 5 balls each. Now, at that point, knowing your number (= 5) does nothing to change the probability of being in the large or the small box. Both boxes will pass a 5-ball stage. After round 5 both boxes are still identical. If there was an a priori chance of being in the large or small box of 50-50, then that will still be the case after round 5. Knowing your number is Bayesian non-information. You cannot simply ignore time, or better said, the ordinal numbering of he balls.

    What if, when the Big Bang happened, from a finite small point of pure energy, the Universe was created instantly? I mean it went from 0 to infinity in no time at all and the energy contained in that point was finite. That would mean that we no longer need dark energy, because space-time and mater/energy are expanding in something that is infinite at an every larger acceleration rate, like a continued explosion that never ends. So the universe itself is Dark Energy, something that we cannot detect, that's because its literally nothing,its just a sort of space in which everything else is allowed to expand into that has no energy or it has anti-energy, and all the rest is moving from a high energy state to a low energy state, all the way to nothingness.

    I think that once a species is aware of all this, the odds shift. All this may apply automatically with a group of beings unaware and moving about making choices unknowingly. But once they become aware of their chances, they now get to cheat and make new decisions based off those odds. In a nutshell, it may very well be automatic and unavoidable to meet doomsday...unless you are aware said doomsday is approaching. Sending the theories out the window.

    That all ok, but if we take baby steps like going to gas station to stop an pee ! We would have to stop places like Mars and moons of the gas Giants to pick up more fuel . While there are on there way, there develop better and better propositions system . Catch a asteroid big enough to mine for mineral , fuel , protection , water and more living space . Spin it to give us gravitational to work better and stay in shape . If you just send egg heads, they'll just seat on there ass for 9 years . They just can not seat there doing nothing , you need building more ships , solar sails to use to slow down smaller ship to use on new sun, solar wind for braking us . Mother ship can orbiting around solar system to slow it down . We need a planet with families and friends to call home and goals to keep us going to better our self's and human race. We'll go crazy on a ton can , with out support . Were sociable species that need our world around us to make us sane so we can make to where we're going .

    This makes so much sense on a macro level. GR tells us the background or stage (space) is dynamic, therefor QM must take that into account. Einstein tries this in the 1950’s but it was a mess. In 1965 the Wheeler-DeWitt equation attempts this, but is unsolvable... until you utilize the information in the connections of space. Those ideas and that path seems seem like a very logical way to reconcile GR and QM. This is currently my level of understanding and I get lost in the math beyond that, but it seems like the idea for the structure and form of loops comes from the connections utilized in the math. Going from mathematics and abstract understanding to a solid picture is always the hard part. Moving from analogy towards reality. Love this stuff. Graphics guy or team is amazing. Best in the biz.

    String Theory is a baby boomer sociological phenomenon. The work done within the field is valuable, the insistence on pursuing it as a description of reality however is irrational and simple cognitive bias. Scientists who worked their whole lives on this problem, whose grants depend on this problem being alive, and whose reputation is just as anchored to this theory, refuse to acknowledge the failure of the theory, since that would mean admitting the convictions and promises made for years are wrong, and have been wrong for a good while, without them noticing it.

    Okay, so the Big Bang could not have happened because before time there could be no cause and effect to create the universe. And they solve this by postulation a eternal universe without a beginning? That sounds like the easy way out, sounds very scientific, sounds like bullshit. I have been told a lie my whole life and since I was 8 everyone avoided my questions about cause and effect telling me that this was too complicated for me to understand and that I should just trust the scientists. Yeah sure, just invent 11 dimensions, branes and unicorns to compute your way out of this. It is just as logical to postulate a creator at this point.

      Yup, if our universe is eternal, then what caused our eternal universe into existence? Because the cause and effect is how our universe works. Every effect in our universe must have a cause. That’s why the only logical way about the origin of our universe I could think of is that a creator must be outside our universe and created our universe. Because after all, how can a creator, who is inside our universe, created our universe when our universe has not been created in the first place, right?

    What's funny about this whole video is there is already interstellar travel now. There are people and other species of extraterrestrials living on planets in our own solar system. Why does everyone involved with this continue to lie to the public? Think about it, the government nor NASA is ever going to come out and tell us...one reason is there would be alot of people having to answer for lying to the public and to make a long story short...there would be charges brought against people for this reason. So simply do the research yourself and if you dig in the right places and deep enough, then you find out some things that will have you shaking your head because everything we you were taught is a lie. Now you can think I'm crazy if you want, I really don't care and if you do then it's because you don't know the truth and you are thinking exactly how the government wants you to think. Enough said, do your homework and you will find out things that should have been told to the public a long time ago.

    "Real companies are gearing up to mine asteroids... there's no obvious deal breaker here" That is exactly the obvious deal breaker though. Real companies have shareholders who only rarely will pursue profit beyond the current fiscal quarter, let alone will they wait 70 years for their first profit (longer than they'll be alive). Then even if you find a group of shareholders who will wait that long or taxpayers who will subsidize it that long (pure science fiction), then it's... still going to be for profit. You can forget a Dyson swarm, they'll bust up Mars to build baby Yoda dolls and hematite hamburger wrappers to extend how long burgers stay warm. Sorry dude but while the technology exists, no civilization that bases its decisions on the profit motive will ever be capable of deciding to do this.

I learned about virtual particles from this channel and am confident it is a real phenomenom of actual particles and not just a mathmatical cheat. Is there an estimate of the volume of virtual particles.... can virtial particles account for the evasive dark matter/energy that everyone agrees is out there. Or is dark matter's mass (or gravitational pull) simply bleeding over into our dimension from an adjacent parallel dimension. I would love to hear this adressed. Thank you. Jay

    When it comes to the inverse square rule and solving Schrodinger equation we use spherical coordinates. What would a mirror image be in terms of spherical coordinates would it be replacing theta i with - theta i and r with minus r.. obviously for r it would not matter...
