  1. You are looking at photons right now in reading this. Now just take it for granted that I entangled one of them. How would you tell it apart from the other trillions of photons, and then to prove entanglement you need to measure it which first means isolating the entangled proton, then measuring it, which would invoke Heisenberg's indeterminacy principle making an accurate measurement if not impossible, at least always suspect. Note, I am not arguing that entanglement happens, just wondering how one would find a proton that is entangled say a million miles away?

  3. Given that current generation PAC-2/3 interception missiles can top Mach 4, their speed deficit against say Avangard and Starry Sky-2 hypersonic glide vehicles is perhaps less of a challenge than keeping track of these highly manoeuvrable devices as they actively evade defence systems. That they achieve their impressive success rates via direct kinetic impact (rather than nearby fragmentation) I find quite staggering. Perhaps the real test will come with the future deployment of the BrahMos II Russian/Indian scram jet powered hypersonic cruise missile which will be capable of Mach 8-ish.

  7. I just found this on the net for the longest entanglement yet, but this at least was contained to optical fiber. Physicists from the Austrian Academy of Sciences have succeeded for the first time in entangling photons over 248 kilometers of optical fiber. For quantum communication, this is a new long-distance record and a significant step on the way to the quantum internet. Previously, the maximum distance was 100 kilometers. The last time that I looked over this I predicted that entanglement would be used for communication but all the predictions said that entanglement could not be used for communication for several reasons. So did that change or was I watching all Dis info because this involves military codes and the Chinese appear to have the lead here. I also found another article where China demonstrated entanglement with a satellite at a 1000 kilometer range.

  8. I'm struggling to figure out your meaning relating to previous posts. This represents the timing of events along the length of say a train, in a particular inertial reference frame? But the rate is slower than c, which would mean those events cannot be simultaneous in any frame. Are you using the composition of velocity calculation to figure out the velocities or at least check that they make sense? It seems like you should be doing that here.

  9. It seems that this is meaningless. So after writing the equation you now agree it is meaningless? This also seems like meaningless word salad. Velocity is constant and instant acceleration?!?

  10. That is a pop-sci article explanation. In pop-sci articles the authors typically are trying to give the nonscience reader and idea of the overall concept in a very brief article which is usually at the expense of accuracy. Authors of these articles usually use analogies (like the big bang was an explosion) that can be misleading.

  11. This statement is extremely misleading to the point of being just simply wrong - yes the initial state was “dense”, but “tiny” is a difficult to define term here, and it most certainly wasn’t a “fireball”, and there was no “explosion”. This statement comes from a really bad source. It’s not a sphere. That’s a common misconception, the Lambda-CDM model only meaningfully describes how the universe evolved after a certain point in the very early universe. It has little to nothing to say about how the initial state came to be, since this requires physics that we do not yet have. Yes, but it does so from every point - all distances increase over time, so there wasn’t one central point where everything started.

  12. From a different perspective, it appeared you were badgering a newbie, @Benjamin Karl, who was not making a claim but rather requesting opinions on the claims made in a video. Whose points he courteously summarized when asked to. While he could be encouraged to dig deeper for other sources, I am not sure that your tone was that of a friendly guide in that quest.

  13. Darwin claimed that a lightning bolt hitting a pond created life, in his letter to Hooker. In 1871 Charles Darwin wrote a now famous letter to Joseph Hooker which included some of his speculations on the spontaneous generation of life in some - warm little pond. The letter was mailed to Hooker on February 1st, 1871. Down,Beckenham, Kent, S.E. My dear Hooker, ... It is often said that all the conditions for the first production of a living organism are now present, which could ever have been present. But if (and oh what a big if) we could conceive in some warm little pond with all sorts of ammonia and phosphoric salts, - light, heat, electricity &c. present, that a protein compound was chemically formed, ready to undergo still more complex changes, at the present day such matter wd be instantly devoured, or absorbed, which would not have been the case before living creatures were formed. You are correct however that this is NOT science as we know it now Actually mathematics works equally well in either direction, meaning that if the universe is inflating all one needs to do is retrace the trajectories of mass to find the zero point. I wonder if you are old enough to remember the big crunch, which was predicted to happen after the big bang ran out of energy and the universe began retracting as gravity began pulling things in reverse. Do you remember when that was settled science. This theory pretty much ended when the speed of expansion was determined to be increasing not slowing however, which was said to be caused by dark matter and energy which represents 95% of all mass and energy. So imagine that 95% of mount Everest is missing, where would it be? If you do not believe me that no one has observed either dark matter or energy, all you need to do is to provide the name of the first person to view these. See reality is not determined by what you or I believe, or do not believe. All that you can do here is to choose one theory over another. There are internet links on Bigfoot too. Really
