Andromeda is moving away from us as it is red shifted. And yet we are going to collide with it. So how can we collide with an object that is red shifted?It's blue shifted.
It should be blue shifted if it is heading our way regardless of the universe expansion.It is.
If the local gravity is overcoming the expansion and that is the explanation for our collision then how can it be red shifted when we observe it?It is blue shifted.
(local dynamics, such as the gravitational interaction between the Milky Way and Andromeda, cannot explain why Andromeda's light appears redshifted if it is indeed moving towards us).It's blue shifted.
But how fast fo electrons travel (or positrons) during radioactive decay modes?Very fast, a large percent of the speed of light. Beta particles (electrons) from Uranium 235 fission can actually move faster than light through water.
Why do artificial satellites of the Earth rotate by inertia longer than artificial satellites of the Moon?Maybe it's just me, but I don't know what you mean. Could you rephrase the question?
Particles in rapid motion turn into waves, and in relative stillness they turn into particles. This is how the phenomenon of wave-particle duality can be explained.First of all there is no puzzle to be solved. Quantum objects can modeled quite well. The problem you seem to have is trying to describe a quantum objects using a classical description. That cannot be done. Quantum objects don't 'turn into' waves or 'turn into' particles. Quantum objects have a wave like property, this wave like property is not really like a classical wave. In quantum objects the 'wave' is localized and a classical wave is not and quantum 'waves' collapse to a point, classical waves do not.
This is what is called; Earth-centrism.Nope. This what is called a fact, the only planet proven to have life is earth. You were the one that said empirical evidence is needed.
Even this (Earth currently being the only viable habitat for life) doesn't alter the very high probability that the UMI principle describes reality in this universe.I of course never said "earth is the only viable habitat for life" because I have no way of knowing that. What is the UMI principle?
Surely cracking fusion energy is not easier than creating a portable machine that is as good as a police drug dog . . .Well we currently have neither. I would wager there is a lot more money being spent on fusion than on an artificial dog nose, especially since a dog works perfectly well.
