About Science Frontiers

Science Frontiers is the bimonthly newsletter providing digests of reports that describe scientific anomalies; that is, those observations and facts that challenge prevailing scientific paradigms. Over 2000 Science Frontiers digests have been published since 1976.

These 2,000+ digests represent only the tip of the proverbial iceberg. The Sourcebook Project, which publishes Science Frontiers, also publishes the Catalog of Anomalies, which delves far more deeply into anomalistics and now extends to sixteen volumes, and covers dozens of disciplines.

Over 14,000 volumes of science journals, including all issues of Nature and Science have been examined for reports on anomalies. In this context, the newsletter Science Frontiers is the appetizer and the Catalog of Anomalies is the main course.

The test compared accurately measured gravity values along the 600 m WTVD tower near Raleigh, North Carolina, with upward, continued gravity estimates calculated from ground measurements. We found a significant departure from the inverse-square law, asymptotically approaching -547 36 microGal at the top of the tower. If this departure ...

... ago this spinning universe was transformed into the expanding universe we see today via that clever cosmologists' ploy called a "vacuum phase transition." Carneiro shows how the rotation of the universe-as-a-whole was converted into overall expansion in a paper submitted to the journal Classical and Quantum Gravity. But even if all of Carneiro's equations check out, angular momentum still had to be conserved somehow during the phase transition. Simple! The angular momentum of the universe-as-a-whole was transferred to the spins of all the individual planets, stars, and galaxies. In ...

... cross the earth's orbit normally have eccentric orbits. There is only one asteroid-like object, called 1991 VG, that has an similar orbit to that of earth. When it was discovered eight years ago, astronomers thought it might be a spacecraft that had escaped the earth's gravity." However, newly discovered 1999 CG9 is much too large to be a wayward piece of space hardware. The best guess is that it is a piece of the moon that was knocked off by an impacting asteroid. (Hecht, Jeff; "Chip ...

A similar patter of magnetic rings has shown up in the Yucatan peninsula. The inner ring is 60 kilometers across; the second, 180 kilometers. The rocks causing the magnetic anomalies are about 1100 feet down. Since these rocks are probably Late Cretaceous in age, this ...

... Dutch team in China detected bright Leonids at 200 kilometers! In addition, some Russian reentering space-craft began glowing well above 100 kilometers. ANAL is a solid phenomenon. Of course, the density of the upper atmosphere does increase somewhat when solar activity is high. Atmospheric gravity waves can also cause the atmosphere to bulge out. But these effects are inadequate to explain all observations. R. Spalding, at Sandia National Laboratories, ventures that ions in the upper atmosphere are electrostatically attracted to meteors and create light when they collide with them ...
