The Time Cube: The Evaran Chronicles, Book 11 , Hörbuch, Digital, ungekürzt, 798min
Time can be a filter.Evaran and the gang travel to a galaxy in the Horologium-Reticulum Supercluster in AD 801,699 to deal with not one summons, as they usually do, but two that are related to each other. The retrieval of Dalton Kingston is one summons, and the second is a day ahead to a ship a few light-years away.The problem is that the summonses lead the gang into the Tenagrin Hegemony, a brutal empire run by the Tenagrins, a snakelike species who have advanced far beyond their natural technological evolution. Another issue is they also want to retrieve Dalton Kingston and have a vested interest in the second summons.Kess, from a previous adventure, joins up for this outing, and with some new allies, they will need to deal with not only the summonses but the Tenagrin Hegemony and a galactic region that fears humanoids. ungekürzt.

The Life and Death of the Universe: The History of the Big Bang and the Ultimate Fate of the Universe , Hörbuch, Digital, ungekürzt, 76min
Many of us on Earth live in a home with a street address, city, and zip code. But we have another address, which astronomers and astrophysicists refer to as our "cosmic address": Earth, Solar System, Milky Way, Local Group, Virgo Supercluster, the Universe. Consider the vast scales that our cosmic address spans. Understandably, it's hard for our brains to truly imagine it. Our galaxy, The Milky Way, is populated with somewhere between 100-400 billion stars, one of which is our Sun, an average, run-of-the-mill star. The nearest star to us is Proxima Centauri at a distance of four point two light years or almost 4 x 10^13 kilometers. A light year is a measure of distance that it takes a photon (particle of light) to travel in a year, assuming it is traveling in the vacuum of space. So, it takes light four point two years to travel from Earth to Proxima Centauri and it would take a space shuttle about 160,000 years to get there, assuming our shuttle was traveling at a little over 4,000 miles per hour. Considering that traveling to our nearest stellar neighbor is well outside of our technological capabilities and it would take more than 1600 times a human lifespan to get there, space travel either to or from other habitable planets is extremely improbable in the near future. The diameter of the Galaxy is about 100,000 light years across, so while it takes four point two years for light to travel to our nearest neighbor, it takes light 100 millennia to travel to the other side of the Galaxy. The universe is estimated to contain at least 200 billion galaxies, according to observations possible with today's technology. When you look at any object at a distance, you are looking into the past. You are seeing the photons as they were when they scattered, radiated, or reflected off of that object. Let's consider the star Proxima Centauri. The photons that leave the surface of Proxima Centauri have a four point two year travel time until they reach Earth. In other ungekürzt. Language: English.
