While the speed of each beam relative to a stationary observer is 300,000
Km/s with both beams travelling in opposite directions, the combined
velocity relative to that stationary observer is 600,000 Km/s. Einstein
did state that from the point of view of someone or something travelling
with the beam the combined velocity of the two beams approaching
collision would appear to be 300,000 Km/s. Einstein was wrong on this
point because for a wavefront or beam propagating at the speed of light,
no time passes and therefore no velocity measurement is possible or has
any meaning in conventional terms.

Not true. The observer on light beam 1 is experiencing time in his own
frame of reference. As far as he is concerned, he is not moving. He
experiences normal time in his frame of reference. And, *he sees light
beam 2 coming to him at 3 X 10E8 meters/sec.

Clearly we are wasting a lot of time, effort and money in bothering to
build bigger particle accelerators (like at CERN) if the combined
collision velocities can never exceed 300,000 Km/s.

They are NOT attempting to exceed 3 X 10E8 meters/second!

Einstein (who is greatly over rated in my opinion) got a lot of stuff
right,

For the purpose of this discussion he got EVERYTHING right and his
theories have been proven time and time again.

but there are some pretty huge gaps in the theory, particularly where
values tend towards infinity. Hence the inability to deal with gravity, a
failure of the theory in dealing with black holes and an inability to
deal with super luminal velocities. Richard Feynman was a far better
theoretical physicist who actually invented ways of reconciling and
sidestepping some of the paradoxes inherent in Einstein's equations.

A black hole is not a paradox. It is simply enough mass such that its
escape velocity from its huge gravitational filed is greater than the
speed of light. What is so paradoxical about that? The only paradoxes that
arise in Einstein's equations occur when people make assumptions that
certain universal constants like the speed of light can become variables
and then the ridiculous paradoxes start to occur. If we try to change the
constant pi, wouldn't we get a lot of unrealistic calculations? Changing
the value of c is the same as trying to change pi.

Just as Einstein refined Newton's ideas, future physicists will regard
Einstein's theories the way we regard Newton's; a good approximation for
everyday use, but not a true description of the processes.

Maybe in 100 years or so. We are not even close to such a refinement right
now. Maybe we never will be.

How on earth did NASA get astronauts to the moon using just Newtonian
*mechanics? The mind boggles. *:-)

The moon is only 450,000 miles away. All velocities, distances and times
involved in a trip to the moon, or Mars, are as Newtonian as a trip on a
jet from London to New York. :-)

Last time I checked the moon was somewhat nearer to 250,000 miles away :-)


You're right. I was thinking of the round trip :-)
