First I wish to offer my encouragement to all in the SETI league. In my opinion manned space travel is too inefficient a means to seek out and discover life in and beyond our solar system. Radio astronomy and SETI could accomplish this far sooner and far cheaper.

THE SETI LEAGUE

It is quite possible that some other civilization is broadcasting a radio beacon or message in our direction. Radio telescopes are used to search for these artificial signals, and also to detect any inadvertent leakage from communications or radar. The traditional strategy for 40 years, radio SETI i

THE NEED FOR INNOVATIONS
Article

Innovation in the SETI field is highly appropriate for four major reasons. First, the history of scientific discoveries teaches us the value of widening the array of approaches and research methods. It is quite common for a breakthrough to result from a new, fresh, unorthodox strategy or research me

OPTICAL SETI

Optical and radio SETI are similar in that each uses telescopes to search for artificial signals from many light-years Instead of searching within the radio spectrum, however, optical SETI tries to detect pulsed lasers, infrared messages, or other artificial optical signals from many light-years awa

THE INVITATION TO ETI

Before we can understand the third major SETI innovation, it is important to understand the likely nature of ETI.

ANOTHER POTENTIAL INNOVATION

Let's conclude by exploring another potential innovation one that could be very useful but has not happened yet. This potential innovation is the introduction of unassailable research designs into the UFO field. Many researchers in the UFO field see themselves as similar to SETI researchers: they, t

A FINAL THOUGHT

3. THE EFFECT OF SUPERNOVAE
Article

A supernova results from the explosion of a high-mass star after its hydrogen and helium fuels are used up, at the end of its lifetime. A supernova exploding within 50 ly of the Earth will have a catastrophic effect. The 1040 J of energy produced in the first few days bathes the earth in a total amo

4. THE EFFECT OF GAMMA-RAY-BURSTERS
Article

Gamma-ray bursters (GRB) are a recently discovered phenomenon, in which some 1045 J of energy are released in a few seconds. The ones that have been observed on earth appear to be distributed uniformly across the observable Universe. Their power is such that we are able to detect GRB right up to the

2. THE NATURAL LIFETIME OF A CIVILISATION
Article

I assume that stars like our Sun have been forming since the formation of the Galaxy some 10 Gyr ago. Observed changes in metallicity since then are not sufficient to alter this simple assumption significantly. Our Sun is now about 5 Gyr old, and has an expected total lifetime of 10 Gyr.

7. CONCLUSION
Article

Conventional models imply that supernovae and gammaray-bursters will extinguish life on planets at intervals of about 200 Myr. Since this has not happened on Earth, either these conventional models are wrong, or else life on Earth is probably unique in the Galaxy. The first case predicts a median ag

5. MASS EXTINCTIONS ON EARTH
Article

The geological and biological record shows a series of mass extinctions of life on Earth. The most famous is that at the Cretaceous-Tertiary (KT) boundary, which was almost certainly caused by an asteroid hitting the earth about 65 Myr ago. The KT mass extinction wiped out the dinosaurs, and paved t

6. WHY ARE WE HERE?
Article

I have identified two causes that should wipe out essentially all life on Earth roughly every 200 Myr, and yet we are here. Two possible explanations are: • The calculation of either the timescales or the severity of the effects is erroneous, or • We have been very lucky! In the first case, simply m

Confronted with clear evidence that the phenomenon being observed was not a conventional radio astronomy detection, Mr. Stephens hypothesized that he was observing communications from an extraterrestrial civilization beamed somehow directly into his computer, through a mechanism unknown to humankind

In the present case, I must give serious consideration to the hypothesis that Mr. Stephens is seeing glyphs and patterns in random noise, precisely because that is what he fervently wishes to see. In fact, in addition to alphanumeric and mathematical

WHY DO WE SEARCH?

Why do we seek distant intelligence, even in the face of repeated failure? Is SETI just an extension of normal science? I suggested in 1993 that we search for communicating civilizations in the hope that contact with intelligent others will introduce new and hopefully positive factors into human aff

ACTIVE SETI
