Somebody referred to Reagan earlier. I seem to recall there was widespread disbelief and near panic at the thought that an actor was about to become president. And he changed parties too as I recall. Not everyone today thinks he was a great president but most concede that he was a good president.

I think that Erwin Schroedinger, a respected scientist, whose equation is the basis of all structural chemistry and molecular biology, was not expressing fairy tales, but only his faith. Faith is not a fairy tale.
Tullio

But faith can be misplaced. But everyone is entitled to their own beliefs and opinions in regard to this matter.

If life can start within the boundaries of science and biology then there is no more need for god.

I think they use gamma rays in the first place.

What would the advantage be? Radio waves aren't damaging to living tissue but Gamma rays are.


Much faster way of sending and receiving messages I think. Our atmosphere is protecting us from the most harmful rays.

Gamma rays travel no faster than other forms of radiation, they are just more powerful than ordinary radio waves.


They do travel at a higher frequency.


But frequency has nothing to do with speed of transmission. Frequency is cycles per second. The speed remains the same as that of light.

One thing may be for sure. My theory about whether the POTUS really has any power or whether the power really lies with the congress.

I think the theories claiming that we humans use less than 10% of our brains were from a time when much less was understood about how it functions. They were also a means of providing hope that someday when humans end up using more of the brain all our problems would be easy to solve.

The Post WWII Era, with the Brutal USA as the Policeman, is over.

That one could say is a good thing, because to be honest the US has not been a very good policeman.

In most cases the US does not understand the countries or the people that it meets. It assumes that anybody who doesn't bow to the US model or doesn't like US imports is wrong. Do US forces every once think of relaxing, taking off the hi-tech body protection, the sun glasses, and take there weapons out of the ready position and talk to the locals, and help the elderly with their heavy bags.

And when the job gets tough, usually caused by local reaction to US policies, you usually pull out post haste, before the job is half way finished.

Like the Brits have done any better. Remember, the USA is what Britain made us. If Britain hadn't botched the events leading up to WWII the United States would possibly still be the isolationist giant it was then.

Fission- we have it, it works but in the long run there is a big price to pay that is currently being postponed. What to do with the waste products so that nobody in the future will be put in harm's way long after the last fission reactor is history.

Fusion- we theoretically know how to make it work (meaning getting more useful energy out than is put in) but so far the problems are proving almost impossible to overcome. Once the energy production problems are solved do we have the expertise to manage that production over the long haul and to prevent potential accidents that might make past disasters pale in comparison. Or, will it be so safe that shutting down is as easy as throwing a switch.

Assuming that the planet's population continues to grow and need energy, when the oil, gas and coal run low, we are going to need more than solar panels and wind turbines and all of the other "green" power sources combined can generate to continue living in the manor we have become used to. So, by then, I hope the fusion puzzle will be solved.

Another problem is that bone density decreases in zero gravity and I would guess that probably any relief gained by you or I or anyone else with back trouble would only last while in space. Once gravity has you back in its grasp the previous condition would return.
13) Message boards : Science (non-SETI) : Why not build a space elevator at the moon? (Message 1787482)
Posted 15 days ago by Profile Bob DeWoody
Answering the question about oxygen. It is pretty well established that on or near the surface of the moon water exists in the form of ice. Oxygen can easily be extracted from water. The moon does spin, the rotational period just coincides with its orbital period around the earth. There are suggestion that an elevator could be located near one of the poles.https://en.wikipedia.org/wiki/Lunar_space_elevator


Which costs money. We wouldn't have to perform that procedure on earth.

But, on the moon, assuming a growing colony is the plan, there is no wind and weather to contend with as well as aircraft and the ever growing quantity of orbital debris. Also the strength necessary for the cable is much less than what is needed to build one here. Then there is always the possibility of a catastrophic failure which here on earth could kill thousands of people whereas on the moon a failure would be a financial disaster but the danger to people would be minimal.

This all assumes that a permanent base on the moon is being established without which it is a moot point.

The only problem is that the effects reverse themselves within weeks of returning to earth. I, om the other hand would be willing to spend the remainder of my days either in orbit or on the moon.

Sorry looks like a total waste of money to me , same as the last time , you're not getting my hard earned money!!!

Before dissing L/M too much you might also want to recall it was Lockheed that designed and built the SR-71 which still holds many speed and altitude records. Lockheed also makes the F-22 which is probably the best interceptor anywhere. I think the F-35 has gotten to the point where they have to make it work or a lot of people will be made to look very foolish. The F-35 is another attempt to create a single aircraft that can take on the role of several different types using just one basic airframe. In the past when Lockheed was given a task to do they usually ended up with a system that did it better than anyone had hoped. For that reason, even though I have doubts about their capability to invent a workable fusion reactor, I still hold forth some hope that they may succeed where others have fallen short of the goal.

I have read that just one major collision in earth orbit could close down manned space flight in low earth orbit as it would make it impossible to prevent more serious damage. That is until we figure out a way to clean up the mess we have made over the last 60 years.

Instead of trying to deal with all the problems associated with constructing a space elevator here on earth. The moon would be an excellent testing ground for building future space elevators on earth or at Mars. It would also make getting to and from the surface of the moon very cheap in the long run.
