One of the most interesting articles of the year proposes a new theory that pulsars are extraterrestrial beacons of some sort. According to the author, a number of odd characteristics of pulsars are best explained by intelligence, not physics. This article is an absolute must read. For more info about some of the anomalies found in pulsars, read on...
Here are some of the anomalies reported due to recent high-resolution measurements:
- Pulse Nulling Pulse transmissions may be interrupted for seconds or hours. When resumed, varying parameters continue from where they had left off!
- Time-Averaged Regularity Time-averaged pulse contours do not change over days, months, or years. Timing of averaged profiles is similarly precise.
- Single-pulse Variability Timing and shape of individual pulses vary considerably.
- Pulse Drifting (certain pulsars) Individual pulses occur successively earlier and earlier within the averaged profile ("drifting pulsars"). For certain drifting pulsars, drift rate abruptly shifts in value. Or drift may be random with occasional recurring patterns.
- Polarization Changes Polarization parameters vary within individual pulses, but time-averaged profile of polarization is constant.
- Micropulses About half of observed pulsars exhibit micropulses within individual pulses. Micropulses typically last a few hundred microseconds. Or they may have oscillatory periods.
- Pulse Modulation Signal strength may wax and wane over a series of pulses. Or this may be seen only when sampling every other pulse. Or maybe only at particular times in the profile.
- Mode Switching More than one stable pulsation mode, with sudden switching between them.
Pulse Grammar "Grammatical" switching rules. - Glitching Pulse periods grow at a uniform rate (as though spinning pulsar is slowing down), but occasionally the period abruptly changes to a smaller value (pulsar instantaneously assumes a higher rotation rate?) and the sequence continues from there.
Now the question is, suppose that the author is correct and pulsars are beacons that transmit intelligent signals. What are they saying? One proposal is that they are intergalactic warning beacons -- cosmic lighthouses to warn of recurring galactic superwave explosions. However, I doubt this -- why would these beacons exhibit short-term variability if all they were there for was to issue alerts for explosions that only occur on multi-million-year timescales? It seems to me that the resolution of information-change is quite high leading me to suspect that these "beacons" -- if that is what they are -- are being used to transmit data on an ongoing basis. One possibility is that they are used to measure gravitational distortions over long distances -- perhaps some advanced civilization uses this technology to graph fluctuations in the shape of space for some purpose. Or perhaps these beacons mark wormhole jump-point locations, and quality readings. Another possibility: Are they some sort of cosmic GPS network that enables a sort of universal coordinate grid for navigation? Or are these deep space data relays -- perhaps beaming news reports between galaxies? An interstellar Internet? Another possibility: Are they intergalactic Blogs? If so, why aren't they listed in Syndic8 yet?




There's one issue with pulsars being some kind of intelligent beacon (or a "device" constructed by an intelligent race).
The data provided by these beacons is immediately obsolete (unless they are in the future...) - so I don't think they are some kind of relevant data messaging system.
Why build a beacon that uses speed-of-light as a protocol, when that beacon is obviously designed to be "seen" from more than several light-years away? If it is a lighthouse of sorts, the "rocks" are already hundreds of years "old" when you see the light.
A more frightening thought is that they ARE markers- and they are marking something so dangerous that it MUST be indicated from a great distance, and for a VERY long time. Perhaps roving black holes, or some other kind of space-time disturbance.
