It is heavily tested over and over and the majority of drugs and biotech companies fail because of the time and money it takes to even put a single drug on the market.

The only thing that's really "man made" in this case is the formulation to synthesize these drugs. Coming to pharmaceutical companies making literally billions from selling drugs, it's like any other market chain on earth. Fruit produce for example, is a billion dollar trade industry. Companies make trillions. But its all natural producst. Does your argument apply here too? I don't think so...
      2. Since the arrival of modern medicine, mortality rates from various dieseases and disorders has dramatically reduced. But for your sake of argument, lets consider that allopathic medicine or modern medicines don't work. Then we should be seeing even higher death rates from diseases like smallpox, polio etc, given the fact that the earth's population is higher than when it was during the times of the above mentioned diseases. But, the mortality rate is relatively low as observe. Is it allopathy? Is it ayurved? Or did nature decide to suddenly heal and make humans stronger (not evolution)? Think about this as well...

      @@djsandbird Well you could say that the analogy is just an optical illusion but in reality, it is not. You can visualize it easier if you use objects on a bigger scale like a planet near a blackhole against earth. The planet near a blackhole experiences time as normal, but when the people from earth observes the people near the blackhole, they would see everything going relatively slower, hence, different perspectives but on a bigger scale. This goes vice versa as well. The people near the blackhole would see the time on earth move faster. Itll be like watching a timelapse.

      I found the test using two airplanes flying opposite directions done in 1971 online. The result is that the clock on the eastward ticks the slowest and the one westward ticks the fastest but the one earth is in btw. But its the one on earth that travels the least in space-time. How to explain that? Also the greater the speed the slower the time. But is that the speed observed or the speed to an absolute media? Both airplanes have speed observed by the one on earth. Why the clock on earth is slower then one of them in airplanes?

      It might be that movement is a resource of an object such that
      when most of the resource is being used to move in one direction
      there is proportionately less available for movement in any other direction.
      Since a body aging is simply the living processes wending their way through a programmed path and these processes consist entirely of particles moving in
      many directions relative to each other then the amount of that movement will be less because most of the movement resource is being used up in the direction of travel.

      Time dilation has no significance for time travel in physical plane. It actually indicates the depth of space-time while observation made on speed of light is a projection at the surface. And time dilation said to be due to gravitation is also not true, it indicates the difference in levels of crests and troughs along the surface of space-time.

      @@bono95zg See the contradiction in these statements ?
      Statement 1: 7:24 "we understand that this is not really a dilation, the ticking of time has not changed, it is simply a matter of perspective"
      Statement 2: 7:37 (twin paradox) "since the paths don't have the same length through spacetime, at their reunion the twins are no longer the same age"
      (physically)
      Spacetime Minkowskians can not explain the twin "paradox", since it is an abstract geometrical/mathematical concept not fully in sync with fundamental physics.
      In this concept it might as well have been the earth twin which accelerated away from the travelling twin (then not travelling),
      and the earth twin would have been younger because he/she travelled a longer distance in spacetime.
      In fundamental real physics the rocket twin transforms chemical energy (the fuel) into kinetic energy (the whole rocket).
      And that kinetic energy is immediately balanced with lower internal atomic energy, a combination of lower kinetic energy of electrons, quarks (which is the physical time dilation, a changed rate of internal change in matter), and lower binding energies in sync with that. Relative to the earth, which did not accelerate. And no no no, it does not require General Relativity to explain it, it is not the acceleration (or the acceleration phase) itself which causes this physical time dilation. It is the velocity caused by the acceleration, caused by the transformation of energy, which causes it.
      That is why one twin becomes physically younger,
      not because of some "geometrical perspective". Time is physical change, not a dimension.
      When you understand this, you also know why an object being accelerated to close to the speed of light, does not have increased mass. Its internal energy is lower in the same amount as its kinetic energy as a whole, the combined amount of energy (and therefore the mass) stays the same. Energy can not be added to the universe by setting objects in motion in it.

    Btw an important distinction. Only causally unrelated events' order don't matter. If two events are causally related, then all observers must agree on the order. They might not agree on the spatial or temporal distance between then events but they have to agree to on the total spacetime distance.

      This is confusing, the Lorenzian geometry mentioned at the very end, with the cone analogy. It is just stated as space-time’s “peculiar” geometry that restricts order of events, as you mention. But what makes up the ‘peculiar’, ie - what restricts order of events from warping say into a curved loop and then out again. Like, if one sees 1-2-3-4-5, why couldn’t another see 1-2-3-4-3-2-3-4-5, right? Not that you would see it in real life, but theoretically why not...

      @RetzyWilliams Před 3 lety +1

      @Snap-off - in terms of space alone, gravity, but it is only a contextual bias, because a plane falling will contextually allow me to fall down and then suddenly fall up. But, in terms of sequence it is falling towards highest gravitational source, so I know what you mean. BUT - what from some other theoretical observer, why no warping permitted, you know. Why can’t they see you loop in between, what literally in space time prevents that

    Plot twist: Einstein traveled ahead in time and watched this CZcams video and stole the idea on time dilation.

      @@ScienceClicEN By the way, is the part at 8:40 an accurate embedding of 2D (t,r) Schwarzschild geometry in 3D space? I've been curious about trying to do this but I'm not sure where to look.

    • @ScienceClicEN
      @ScienceClicEN  Před 2 lety

      @@eigenchris If I'm not mistaken it's strictly impossible to faithfully embed a lorentzian geometry into a euclidean space, because of the signature (one can't imagine representing the lorentzian triangular inequality in an intuitive geometrical manner for example). So here I used a trick. In a way it's the same trick which is used throughout the whole video : I made a "euclidean equivalent" of the Schwarzschild metric, and embedded it. To make this "euclidean equivalent", I used the same method as in my video "We all move at the speed of light" : I start from the regular lorentzian metric (setting c=Rs=1 for simplicity) dτ² = dt²(1-1/r)-dr²/(1-1/r), and I swap the roles of proper time and coordinate time. This is as far as I know one of the only ways to "convert" a metric from lorentzian to euclidean geometry. We thus get the following "metric" : dt² = dτ²/(1-1/r)+dr²/(1-1/r)². This is a euclidean metric and it can be faithfully embedded, giving a surface that looks roughly like what I've shown in the video. Sadly enough I've been looking for years and it's the best "embedding" I've found so far for the Schwarzschild metric.

    4:04 If the surface is curved for one but not the other, the directions are also different. If both travel the same curve, however, the directions are the same. So the second point is not always relevant; it is only the difference in directions that matters.
