There are a lot of things that are lumped under the rubric of "Quantum Mechanics". It all started with the discovery that energy from a heated Black body radiated only at distinct frequencies instead of a continuous spectrum. This is easy enough to see why if you look at a standard model of the atom with the electrons orbiting in different radii around a nucleus. Jumping from one allowed orbit to another requires an input or outflow of energy that corresponds to the different energy levels of the allowed orbits of the electrons.

The electron of course carries with it it's own level of fiction which helps us understand and control it.

The uncertainty principle says that in trying to measure both position and momentum the act of measuring will will alter one or the other of these quantities. Then things get stupidly weird with the Schrodinger wave equation, his dead or alive cat and quantum entanglement.

A quantum computer mat simply be the fact that the smaller and therefore closer together transistors the faster the computer. If these were shrunken down to atomic size the expectation is that the computer would be faster, I have not seen an explanation of how a computer that uses any of the weird quantum dualities would offer an advantage over a modern day computer.

The problem is that there are thousands of artillery tubes pointed at Seoul from within the North Korean border. Seoul is within range.

it seems to me that a sphere would always appear as a disc and that crossing it at any angle would be discernible. They also use the wobble effect of a planet on it's star to imply a planet's existence.

Retracted: I see now that we and the planet must be on the same line of sight with the star.

If we can find a planet of this size at 180 light years ---does that mean that there are no Earth sized planets within, say, 50-100 light years??

It may be that this planet is somewhat large and close to it's sun and therefore may be discernible as it transits across it's star on a frequent basis. So if there are Earth-sized planets within this distance they may be further out from their star and/or not in our line of sight.

In my grade school days in Key West Florida about half of my classmates were Cuban. They are very fine people. I think that we should allow two new baseball teams into the Major Leagues--one in Havana and another in Santiago.

It is a false hope that the Exiles in Miami will ever get back their property that was seized when the Batista Regime was ousted by Castro even if it were gained by industrious work.

I think in the long run engaging Cuba is the right thing to do for their people.

My alter Ego has often thought about this island Nation of 11 million people.

Probably correct.

The false colors are truly false. They represent temperature and the wavelengths that are associated with them. A color that we can see is substituted for a "Color" (wavelength) that we cannot see; such as x-rays and so on.

In this way we can get some idea of the totality of radiation and it's type from a cosmic source.

A higher state of complexity or order can be reached; but what is required is an input of additional energy. This energy can come from a source that is outside of the system being considered.

we would all go to Alaska and live on Whale Blubber, caribou, elk, seals, salmon and Arctic Char.

Yum.

The Voyager space craft is only 13 billion miles from earth and will take another 300 years to reach the Oort cloud which is the outer limit of our Solar system.

The nearest star system is about 4 light-years away or about 20 Trillion miles.

We could probably detect TV and Radar at these distances --but for the past 50 years we haven't heard a thing as far as we know. It could also be that we did hear them but never had the smarts to decode their transmission--this is not likely in my opinion.

Assuming that there are OTHERS to find us out there in our Galaxy and beyond; we won't be found since we are not broadcasting any powerful, focused blasts out into the cosmos.

If They were close enough to pick up our radar or TV broadcasts, we would have heard them by now ourselves.

I don't think that any legitimate contact would, could or should be kept secret.

The best reason to establish a Moon base may simply be to learn and advance a variety of new technologies.

It would be refreshing to have something other than warfare to drive these developments.

how do we think we can detect some signal from outher space


Many of us believe, since we have been listening for 50 years now, that only a very high powered, intentionally focused beacon (laser or microwave) type of signal could be detected. Since THEY would not know that we are here, this would likely be a slewing type of transmission and would likely not be a constant signal burt rather a one-time event.

As far as I know, we are not transmitting such a message. Let's hope that: if another civilization exists, that they are not as ignorant as we are in this regard.

You are getting into the realms of perpetual motion machines which we know cannot be.


As I have noted in my posts. However, do you think that the Viking and Voyager spacecrafts will go on forever ??. Do you think that the moon has been orbiting for a long time. Does an Oscillating circuit cooled to absolute zero run forever?

It all may come down to context and what may be "pregnantly perpetual".

I suppose that you would say that a system cannot be more than 100% efficient---it all depends on where you draw the lines around the "SYSTEM" . For instance today's home Air conditioners run at well over 400% efficiency. Don't believe it? : divide the BTU output by the kilowatt input. How do you account for this---the extra energy comes from the Atmosphere which is cooler than the compressed refrigerant in the air conditioner.

A SEER of 16 means that you will get 16BTU's of cooling out per watt of input.

some sort of anti-gravity device


All you need to do is figure out how to cross magnetic lines of flux. Put a big South pole magnet on the tail of a rocket and then figure out how to achieve the equivalent of always having another South pole directly behind it.

Impossible of course but fun to think about--actually that is how an electric motor works. Switching the fields of the commutator of course incurs losses that keep it from being a perpetual motion machine.

For a brain exercise--try designing a motor using a Mobius strip. Can you keep it from running down by assuming a frictionless medium on which the magnetic "Cars" ride back and forth.

Just keep going around in a circle and then switch the track at the last instant to the launch angle.
