That's right

A laser's beam dispersion will be much less than the dispersion of microwaves.

Perhaps less power might be needed to communicate over long distances. Modulation techniques might be different.

Are we now looking for laser signals from our aliens. If so, what type of modulation do we expect.

All very good questions for those running a SETI project to answer.

A watt is a joule per second. Lasers are most commonly rated in Joules. They are building a Facility with joule in the title in Europe involving Lasers used in Fusion research.

The result that you cited was achieved in 2005. I have first hand knowledge from a retired scientist who worked at Lawrence Livermore Laboratory and can state that the number I put forth was correct. Laser output passed more than 1 billion Joules some time ago. The pulse was around one billionth of a second long.

These lasers are now intended for nuclear fusion research.

We could send a focused beam back to anyone who told us where they were. We would send it at the same frequency that we received their message. We can command billion joule lasers but I am betting on microwaves.

There is no "They" that think we are a flawed creation. So far as we now know there is no "They" within detection distance whatsoever. Time and technology may change this--at such time we may then like to speculate on their perceptions and sensitivities.

What we are hoping for and most likely to find, if "They" exist, is most probably:

A civilization who is sentient to at least the degree that we are and has learned to communicate across vast distances.

Whether or not they want to visit us will depend on if we find "Them" and how far away they are and any resulting dialog. Right now it doesn't look good for such an alien race within as far as we can monitor electronic emissions.

Since we have yet to find a single planet that is truly Earth-like in the sense of being able to spawn and support intelligent my estimate of 5 or less in the galaxy is most likely more accurate then the estimate of 3 million and just as uncertain.

Figure out the average volume represented by each of these putative 3 million planets and then see if we have found any such planet within this distance from Earth --perhaps in the future as we search farther and farther out.

Many of these alleged "Costs" are already sunk costs and may reflect the rate at which dish time is charged to and recovered from various projects. A lot of the Hoopla (possibly unwarranted and not well verified) may be to attract funding from various agencies and funding sources. Public research entities (such as universities , government labs and their allied agencies) are funded by a Government budget (Federal, State) for salaries and operating expenses. If they attract additional Grant funding then the excess cash is recorded in the financial VP's little black book to disperse elsewhere.

If these Dish locations do not have signal Processing Gurus who can probe for intelligent or sentient being emissions then they have no business of being in the SETI game whatsoever.

The basis that I like to think of requires narrow parameter ranges of a dozen or more variables.

For instance.

Rocky planet with water
magnetic field
Circular orbit
Moon to lock a stable wobble
Tides
And the list goes on.

A Federal Republic--if you will.

Posted 23 days ago by Profile William Rothamel
Professor Rothamel has advanced a theory that the WOW signal was caused by a power surge in the amplifier in Antenna number 1?

So what ?

it seems that science can not reasonably account for the existence of the universe we know, and ourselves


I decided that you are right about the accounting for the Universe--where the energy/matter came from and why. In time we may have a better philosophy As for life--we will produce life in the laboratory soon enough that will be above the level of a virus, and we will watch it mutate and reproduce.

If we ever found a rocky planet with water in the habitable zone that had an atmosphere---it just might be possible to look for signs of life( or probable life ) and industrialization by analyzing the atmosphere itself.

prevent us from detecting them.



They would have to hide their planet and it's atmosphere.

If you can't see his mirrors then you can't see his face nor can he see yours.

The only way that the original statement can be true is that THEY are more than 100 light years away and have the means to monitor TV signals that haven't been created yet and won't be for sometime in the future. I presume that :

We would have found THEM within this distance.
They would judge our demeanor by monitoring our TV and radio transmissions which have been travelling for less than 100 years.

Therefore I conclude that:

There is no alien civilization within 100 light years and THEY , if they actually exist< don't know that we are here and are a bunch of warring tribes.

Counter-arguments welcome.

chosen not to make contact with us


If we don't know where they are then they don't know where we are.

as for Godel :

It means within our axiomatic system we cannot prove all valid theorems within the system-we must appeal to outside the system. There are other systems of algebra/arithmetic where this is not true. It also suggests that we may have trouble when the math we use does not explain what we see--or the math predicts something that is not true. I have suspected that this gives rise to quantum weirdness when we examine the smaller physical side of our existence.

What would we have been without the imagination of some great minds in our era?


We would be nowhere without verification of well worked-out theories.

jan,

Yes you are right about infinite surface but finite volume; As I have said before --at the very small our mathematics may be inadequate as evidenced by perceived quantum weirdness

To wit:,

The function 1/x from x=1 to eternity (Galileo horn).


As you approach infinity you are in danger of dividing by zero which throws off our mathematics. If you allow division by zero to produce real world results then i can prove to you that 2 is equal to 1 Which I can assure you is not true in reality.

julie,

If such a field exists then it should be detectable--not just imagined.
