  1. 4:40… using logic based on what you already know ask yourself what would John Newlands say in discussing the accelerating expansion of space with a piano tuner and the energy needed to support a speakers subwoofer compared to its tweeter while looking back in time where a rapid initial expansion is shown pointing to a singularity.

    Here is a copy of some simple calculations regarding CERN's “Superluminal” Neutrino Abnormality announced worldwide in September 2011 @ (v-c)/c=2.48e-5 sec in 453.6 miles creating the biggest question of "why" ever asked in the History of Mankind because it challenged Einstein.. or so they thought. But first ask yourself another question…. 'can you believe everything you are told if someone that wants something is trying to cover it up?'…. again let your common sense and logic makes the following observation.

    These simple calculations exposing an important ratio in physics first observed by Arnold Sommerfeld in the late 40's using the photon (and many times thereafter but ignored because the repeated measurement challenged Einstein as CERN stated again only using the neutrino after Fermilab noticed it too) show using basic math that CERN's Muon phase timed neutrinos measured @ (v-c/c)=2.48e-5 sec in 453.6 miles match the mistaken "superluminal" gain created by SLAC's E158 asymmetry of the weak force ratio which also adds 2.48e-5 sec to the speed of light in 453.6 miles creating an asymmetry in time of 20e-5 sec… showing a simple way to describe gravity as a force rather than its geometry using kid's math.

    A year after these calculations were posted on Nature's Forum next to CERN's scientists exposing an asymmetry in time sending a Google search on "SLAC E158" to 100 full pages by scientists who were trying to figure out why CERN's neutrino data was showing Einstein was wrong "again", SLAC went back over their BaBar experiment's data and confirmed "looking at it differently" time has the asymmetry exposed using a 3rd experiments data and that proved Einstein was correct AGAIN by eliminating the uncertainty principle he was ridiculed for refusing to accept. The change in physics human nature is trying to hide in a loose cable shows gravity is is connected to time for a logical reason just about anyone can understand when explained properly in layman terms.

    Open up a calculator and it's easy to see for yourself and follow along. "{a}" is the algebraic symbol of the value in effect of WF Asy but not needed for simple math which makes this discovery very unusual as anyone with basic math skills (or a calculator) can see the data match to decide for themselves what is real and what is politics as usual.

    SLAC's E158 Weak Force Asymmetry {a} ratio is exceptionally specific and "using clocks" adds the EXACT distance light travels in one hour to the distance light travels in one thousand years expressed as distance showing many scientists for the first time to see how space is connected to time.

    3600 sec / 1000 years = 3.6 seconds WF Asy {a} added in one year.

    3.6 sec x 186282 (speed of light) = 670615.2 which is the {a} WF asy in distance added to the speed of light in one year so….

    670615.2 / 365.2425 days in a year = 1836.082055072999 is the {a} WF asy SOL distance added to speed of light in one day

    1836.082055072999 / 24 hours = 76.50341896137498 is the {a} WF asy time/distance added to speed of light in one hour

    76.50341896137498 / 60 minutes = 1.275056982689583 is the {a} WF asy added to speed of light in one minute

    1.275056982689583 / 60 seconds = 0.021250949711493 is the {a} WF asy added to speed of light in one second

    Now if the Earth were bigger and CERN's neutrinos had traveled a little over 186282 miles (one second + WF Asy gained @ SOL) we would be done, but since they only traveled 453.6 miles we need to keep going till we get to the value of {a} added in 453.6 miles. So we divide the miles light travels in one second by the miles CERN's neutrinos traveled.

    86282 miles or one second/453.6 miles, the percentage of a one second gain which is = 410.6746031746032

    Now we divide it into the WF Asy one second gain from above (.021250949711493 )

    0.021250949711493 / 410.6746031746032= 5.174644243208279e-5

    That just gave us the total forward and back total neutrino oscillation WF Asy {a} time gained in 453.6 miles. Now notice it is almost exactly double CERN's 2.48e-5 sec SOL gain announced Worldwide before the politics SLAC ignored stepped in.

    The next two calculations dividing it in half and using CERN's 2.48e-5 forward arrow "stopping point" to add the .10e-5 sec remaining difference to the other half and show it fits exposes a 4th oscillation atomic phase and a second reverse arrow connected to time. In layman terms it adds a 4th part called the missing gravatron to the atom that was sitting next to the electron in plain sight all along. (This was posted on Nature Forum before SLAC went back over their BaBar data and confirmed the asymmetry in time giving the discovery a sigma 14 level of certainty in Nov 2012.)

    5.174644243208279e-5 /2 = 2.58732212160414e-5 sec

    That gave us the forward arrow of time WF Asy gain in 453.6 miles that is .10e-5 sec over CERN's 2.48e-5 sec in CERN's equation @ (v-c)/c=2.48e-5. So we just subtract the difference:

    2.58e-5 – 2.48e-5 = .10e-5 sec

    And add it to the other half: 10e-5 + 2.58e-5 = 2.68e-5 giving the second reverse arrow an asymmetry in time of .20e-5 sec, the difference in size of the forward arrow @ 2.48e-5

    2.68e-5 – 2.48e-5 = .20e-5 sec

    So using basic math we see that CERN's neutrinos traveling at (v-c)/c=2.48e-5 sec in 453.6 miles creates an asymmetry in time of .20e-5 sec just as predicted using CERN's forward arrow gain of 2.48e-5 sec to show where we "fold" space and add SLAC's E158 remaining ratio that fits filling in the second reverse Mass oscillation arrow at 2.68e-5 sec. To support gravity connected to Mass oscillation it had to create three separate ratios and that's exactly what this shows.

    If you add an asymmetry to time you must end up with one and to create gravity it must occur in the second oscillation phase as shown so the reverse phase arrow is a little longer. This shows any physicist paying attention and any good physicist half asleep gravity is caused by the subtrahend of the electromagnetic wave as well and the graviton phase is longer than the electrons. It shows the neutrino is the photons force carrier space and is separating the weak force phase timing from the strong force in both an inertial and accelerating state where Gravity is created by the subtrahend of the remaining weak force asymmetry gained. Guess what that creates over time that gets really heavy….

    If the Unified Field Theory equation that exposed the strong force in observation of a speed of light clock and created these calculations was wrong the numbers wouldn't say it was correct and someone would have corrected it going on a decade now. But outside of the music profession it created a deep silence that showed knowledge and a physics degree are not the same thing and human nature remained the same after the answer to the biggest question ever asked was provided by the public with a great deal of credit going to CERN's honest scientists and SLAC's E158 team as well as SLAC's BaBar team (and the US DOE that funded SLAC going back over their BaBar experiments data) who unlike a few people at CERN did not try to hide the discovery that time has asymmetry. And that adds a second reverse arrow to time, and a fourth Mass oscillation phase shown opposite the electron to the atom. The graviton phase was in plain sight all along….

  2. I'm a little surprised that someone drank a whole glass of heavy water. Aside from the cost, I've always heard that drinking a sizable amount of it can potentially cause some issues with the body's chemistry.

  3. I think in the beginning he told that the neutrinos do not have mass, but its not true, they do have small amount of mass. That is the reason why they were discovered at first. If they were massless then the beta decay would have still conformed to the conservation of energy and there would not have been any fuss about neutrinos.

  4. Actually, in normal water, the vast majority of water molecules containing heavy hydrogen won't be D2O but DHO because the nuclei are constantly redistributed between the water molecules.

  5. 6:38 is wrong – they experience weak force AND gravity. If have zero mass and travel at speed of light, then that is really stating at the speed of causality. However causality is bent by spacetime, and just within the event horizon of a black hole all possible futures are directed inwards to the singularity. Therefore it is not be true that neutrinos do not experience the force of gravity: Neutrinos can't pass into a black hole's event horizon and emerge the other side. Therefore 6:45 is incorrect to state neutrinos only feel the weak force out of the 4 forces. Instead should have been phrased as they only feel the weak force that current standard quantum mechanics covers (weak, strong & electromagnetic forces), but do feel gravity which is not get included in the standard model (quantum gravity is speculated to explain what happens at the core of a black hole, but is only conjecture at present). Indeed at 7:35 the diagram states "Neutrinos feel only the weak force (and gravity)"

  6. Camera work driven by producer who is used to the idea that you need to keep changing the image to keep people watching. This is wrong, when the guy is talking about a 'slide' that is full of detail, then keep looking as the screen for ALL the time he’s talking at it, because we're trying to read the slide. Eg 26:24 can’t read the slide

  7. How fast=How interactive and or what flavour? Given the fondness for slight fluctuations bringing about different species in so many of nature's systems and the trouble time has keeping up with nature's true speed demons….maybe they're only poking a part-time toe in our dimensions.

  8. How did they calculate what percentage of Solar Neutrinos they were capturing at anytime? The weather above is changing, the distance from Sun and axial tilt was function of seasons, and Sun having its own Solar Flare cycles. To have a faith in a number is very egoistic.
