Correct. And if the Earth had no curvature, a shadow would "move" at infinite speed just before the sun's rays are parallel to the ground...it is
just a change of direction for the light's emission.
When the laser is turned, new photons are reflected.
Correct, and I can elaborate on something of value here. If you set up a hypothetical laser to shoot a beam into space, as the Earth rotates, that
beam would describe a spiral of light stretching far out into deep space.
Their intersection with the shore is not an object that has a velocity.
I never bothered to read that reference, I just don't spend time on bad science. But it is interesting how he used the waves on the ocean as an
example. I used them to show information could not be carried by them. A particle, object, or quanta of energy constitutes information.
Phase velocity is again not an actual object moving, but a probability function.
Correct again. Think combs with odd and even teeth rubbed together on their flat sides and held up to the light.
They are merely mathematical constructs to describe the location/energy/momentum/time of a particle. They do not travel.
Like vectors.
Wormholes/warp drive: Neither of these methods enables FTL travel. Instead, they "warp" space, causing the distance between 2 points to be
smaller, allowing conventional (slower than light) travel between the 2 points in much less time than it would take if they were at their original
spatial separation. An outside observer may think they are travelling FTL, but it is an illusion. The actual travellers would not be going
FTL.
This is worth quoting in its entirety. I have been harping on the same for a while now. That is transrelativistic warp. People think I am being funny
when I use those terms, but I am deadly serious.
Now for those who think we got our technology from aliens
Mid evil times, yes I know...and I am sure it goes without saying you know that Newton was the first to come up with the quantum theory of light...too
bad he threw out the one for gravity, doncha think?
Well, do you?
If we, as a species, are unique in that we are more individualistic than collective, mistakes like this one would be far more uncommon for most other
species. So it follows, most spacefaring races begin roaming the stars along a line of development equivalent to our ancient Greek times....
There is just over a million intelligent races in this galaxy alone, and even though it may seem like a lot, please bear in mind we may have over a
trillion worlds...and a million is six orders of magnitude less!
It is midnight and I need to go fer now, but it is good to see well informed people making their contributions!
