The U.S. Navy is drafting new guidelines for pilots and other employees to report encounters with “unidentified aircraft.”

For the past 30 years, there has been an orchestrated alarm over how much a trace of a trace gas, human-produced carbon dioxide (CO2), impacts earth’s climate.

The idea was presented as the ‘settled science’ and that there exists a ‘greenhouse effect’ in Earth’s atmosphere and that CO2 ‘traps heat’ or ‘delays cooling’.

New book on cosmology declares: “The universe is infinite; the motions of matter are predominantly cyclical.”

At Principia Scientific International we pride ourselves on providing a platform for our readers to debate and discuss some of the more contentious ideas in science.

In that regard we have pleasure in highlighting Glenn Borchardt’s book, ‘Infinite Universe Theory’ recently made available to purchase as an ebook.
