General relativity and quantam - what would happen?

dre
Here are my two questions:

1. At higher speeds objects appear smaller. Fine. Now if a person is in a tornado ride (the circular ride where it spins around and makes you stick to the wall) and the machine is going at sufficient speed, he will measure a longer circumference since his ruler will appear shorter.

My question is this: wouldn't the entire circular ride appear smaller to an outside observer? Thus cancelling out his shorter ruler? And if the thing kept spinning, would it keep getting smaller and smaller and achieve an immense mass?

2. Mass is both wave and particle. The double slit experiment. Great. But is it possible that mass is not both wave and particle, rather particles traveling along rippled time-space? Small ripples due to objects surrounding the particle, ripples due to the earth, and even ripples due to the particle itself.

1. In the scenario described, the person inside the tornado ride would indeed measure a longer circumference due to the effects of special relativity. However, an outside observer would not necessarily see the ride as smaller. This is because the effects of special relativity depend on the relative speeds and perspectives of the observer and the observed object. So while the person inside the ride may see a longer circumference, an outside observer may not see any significant change. As for the ride achieving immense mass, this would not happen as the mass of an object does not change with its speed. The mass of the ride would remain the same regardless of its speed.

2. The concept of mass as both a wave and a particle is based on the principles of quantum mechanics and has been supported by various experiments, including the double slit experiment. While it is possible that there could be ripples in space-time due to surrounding objects, it does not necessarily mean that mass is traveling along these ripples. The wave-particle duality of mass is a fundamental principle in quantum mechanics and has been well-tested and verified through experiments. While there may be other factors at play, the evidence for mass being both a wave and a particle is strong.
 
OK, so this has bugged me for a while about the equivalence principle and the black hole information paradox. If black holes "evaporate" via Hawking radiation, then they cannot exist forever. So, from my external perspective, watching the person fall in, they slow down, freeze, and redshift to "nothing," but never cross the event horizon. Does the equivalence principle say my perspective is valid? If it does, is it possible that that person really never crossed the event horizon? The...
ASSUMPTIONS 1. Two identical clocks A and B in the same inertial frame are stationary relative to each other a fixed distance L apart. Time passes at the same rate for both. 2. Both clocks are able to send/receive light signals and to write/read the send/receive times into signals. 3. The speed of light is anisotropic. METHOD 1. At time t[A1] and time t[B1], clock A sends a light signal to clock B. The clock B time is unknown to A. 2. Clock B receives the signal from A at time t[B2] and...
From $$0 = \delta(g^{\alpha\mu}g_{\mu\nu}) = g^{\alpha\mu} \delta g_{\mu\nu} + g_{\mu\nu} \delta g^{\alpha\mu}$$ we have $$g^{\alpha\mu} \delta g_{\mu\nu} = -g_{\mu\nu} \delta g^{\alpha\mu} \,\, . $$ Multiply both sides by ##g_{\alpha\beta}## to get $$\delta g_{\beta\nu} = -g_{\alpha\beta} g_{\mu\nu} \delta g^{\alpha\mu} \qquad(*)$$ (This is Dirac's eq. (26.9) in "GTR".) On the other hand, the variation ##\delta g^{\alpha\mu} = \bar{g}^{\alpha\mu} - g^{\alpha\mu}## should be a tensor...
