Acceleration Of Gravity

A photon's point of view

If you could include the dimension of time in this picture you might get a rough idea of why things appear to accelerate towards a massive object - even though they do not themselves experience any acceleration.

From a photon’s point of view, it is emitted and then instantaneously reabsorbed. This is true for a photon emitted in the core of the Sun, which might be reabsorbed after crossing a fraction of a millimetre’s distance. And it is equally true for a photon that, from our point of view, has travelled for over 13 billion years after being emitted from the surface of one of the universe’s first stars.

So it seems that not only does a photon not experience the passage of time, it does not experience the passage of distance either. But since you can’t move a massless consciousness at the speed of light in a vacuum, the real point of this thought experiment is to indicate that time and distance are just two apparently different aspects of the same thing.

If we attempt to achieve the speed of light, our clocks will slow relative to our point of origin and we will arrive at our destination quicker that we anticipate that we should – as though both the travel time and the distance have contracted.

Similarly, as we approach the surface of a massive object, our clocks will slow relative to a point of higher altitude – and we will arrive at the surface quicker than we might anticipate, as though time and distance contract progressively as we approach the surface.

Again, time and distance are just two aspects of the same thing, space-time, but we struggle to visualise this. We have evolved to see the world in snapshot moments, perhaps because a failure to scan the environment with every step we take might leave us open to attack by a predator.

Science advocates and skeptics say that we should accept the reality of evolution in the same way that we accept the reality of gravity – but actually this is a terrible analogy. Gravity is not real, it’s just our dumbed-down interpretation of space-time curvature.

Astronauts moving at a constant velocity through empty space feel weightless. Put a planet in their line of trajectory and they will continue to feel weightless right up until the moment they collide with its surface.

A person on the surface will watch them steadily accelerate from high altitude until that moment of collision. But such doomed astronauts will not themselves experience any such change to their velocity. After all, if they were accelerating, surely they would be pushed back into their seat as a consequence.

Gravity, Speed and Acceleration by Dr. Nicholas Romanov - CrossFit ...

Continuing our discussion series, Pose Method creator Dr. Nicholas Romanov discusses gravity, speed and acceleration and how these concepts relate to Pose, a method of teaching sport-specific techniques.

Through mathematics, Romanov has determined that the body is falling at its maximum acceleration when tilted at an angle of 22.5 degrees. This is the point at which the “vertical direction of (the) body-weight vector becomes dominating.” He defines the terms “acceleration” and “speed” and explains their interactions.

“Gravity gives us (an) incredible amount of acceleration,” he says; however, the doctor believes we still don’t fully comprehend it or utilize it.

“In classical biomechanics, running was understood like rotation is a consequence of horizontal movement. In Pose concept, it’s opposite: rotation is creating horizontal velocity,” Romanov says.

According to the doctor, gravity is the only force that can increase rotational movement, and the only way to increase rotational speed is by increasing the magnitude of the angle of your fall to a maximum of 22.5 degrees while moving.

I don't think I'll ever get it until I truly dare to lean forward.

In the meantime, and I'm not entirely joking here, this would seem to be one of the best videos to illustrate the principle - though they do stretch the 22.5 degree limit.

Safe for work, family; the best posing is all within the first 40 seconds.

Well, I have to humbly admit, the more I listen to this man, the less I understand his "scientific" arguments... and I am a physics engineer, so I *should* be able to make some sense of it all.

He uses all the buzzwords (gravity, speed, acceleration, etc), but the overall explanation makes no sense to me. Maybe it's the langage barrier (english being a second language for both of us)?

Anybody knows of any peer-reviewed articles on the POSE method?

(Note: I'm not denying that the method works, I'm just worried that somebody is trying to give it a false legitimacy through a scientific-sounding discourse.)

No disrespect intended to Dr. Romanov, but I would like to be able to watch his videos and get some concrete advice for improving one's POSE technique. By contrast, when I watch Coach Burgener I always come away with a few new tips or insights about lifting that I can take to the gym that day. In the past I've thought that perhaps I simply lacked the scientific background to comprehend what Dr. Romanov is saying, so it concerns me a little to read a post like #3 above.
