Cosmological Ice Ages Scarry book!

I plotted our sun’s course through space to discover that our sun was born in the constellation Orion. After the planets were formed Earth was covered with a five-mile-thick coating of ice one billion years. We eventually drifted near the Sirius multiple star system and little Sirius B (1.5 solar masses) grabbed hold of our sun putting it in orbit around Sirius A.

Earth was in the Huronian Glaciation which lasted more than one billion years untill we drifted near the Sirius system. The additional light and heat from the two-solar-mass Sirius A and little Sirius B putting out more than 100 times the UV of our sun is the only thing that could have penetrated Earth's thick atmosphere.

During the rein of the dinosaurs the atmospheric wa.s around 30 pounds per square inch. Now it is 14.5 pounds per square inch. Before our sun was captured by the Sirius system earth had an atmospheric pressure of 750 pounds per square inch. Such an atmosphere extended 2,500 miles above the planet. There was no way sunlight could get through an atmosphere extending 2,500 miles aboue the planet to thaw out mile-deep ice over the oceans.

It took the power of a white dwarf Sirius b putting out more than 100 times the output of our sun to get life started. Our sun does not have enough power to keep us out of the ice ages otherwise we wouldn’t have them! Earth has lost 98% of its atmosphere. Over time the Earth expanded one third in size and the remaining atmosphere was laid down as coal, oil and limestone using photosynthesis and light from these giant stars. We have a limited time to get our act together and get off the planet to seed life in other biospheres.
