Alien Life

This blog enjoys exploring a strange world and unusual forms of life. A census of Australia's reefs has found hundreds of new species. This white topped coral crab crab has claws bigger than its body. The segmented forms of shellfish could resemble future spacesuits.

This dendronepthya or soft coral was found near Lizard Island.

Pohls sea urchins, also found off Lizard Island. This writer had the great pleasure of studying in Australia. Lizard Island also contains an excellent resort surrounded by the Reef. Creatures in this weightless environment may hint at the forms of alien life.

This tardigrade, or "water bear," is an eight-legged creature about 1.5 millimeters long. In extreme environments it can suspend all biological activity. In a dehydrated state it can survive great heat, cold and even the vacuum of Space. A colony of them spent 10 days in Space aboard an ESA spacecraft called FOTON-M3. Tardigrades survived solar UV radiation 1000 times more intense than that of Earth's surface. These tardigrade's survival lends support to panspermia, the idea that life could cross Space to seed other worlds.

In deep sea vents, scientists have found organisms surviving at temperatures up to 120 degrees Celsius. The vents are warmed by geothermal heat originating deep in Earth's interior. The source of interior heat is still unexplained, but could conceivably come from a tiny Black Hole in Earth's centre. Worlds as diverse as Ceres and Europa appear to contain oceans. All these worlds are potential abodes of alien life.

I love those water bears.

I'm also quite fond of your ideas about black holes in ordinary places: the earth, the sun, moons of Saturn and Jupiter.

Charles Sheffield wrote a whole series of short stories about the uses of mini black-holes... "The McAndrews Chronicles" 1 & 2 collected them. He imagined a zone of PBHs orbitting the solar system - perhaps he was right?

cc, am glad that you enjoy the posts.

Thanks, graal. Sheffield was a fine writer in addition to being a scientist, and maybe he was prescient about PBH's. Some ideas are so revolutionary they can only be published as Sci Fi.

I think you are right, IT'S A STRANGE WORLD! I couldn't believe those pictures... I still wondering, do they need water to live like us? they seems like Aliens, indeed. I would like to know more about it, where I can find more sources?

Is there really any other word that can describe this latest colorway for the Nike Kobe 11 better than NBA Shoes simply “clean”? Simplicity at its finest, the Engineered Mesh version of the Kobe 11 is featured in a crisp white upper with Cool Grey Flywire, black branding accents, and the KD Shoes For Sale colorway’s coup de grâce: the iciest of icy clear outsoles. The only downside, you’ll want to keep the sneaker cleaner handy whether you’re hooping in these or not to make Nike Hyperrev sure they stay looking pristine. If you agree that this is one of the best looks yet for the Kobe 11 EM, be sure to grab your pair tomorrow from Cheap KD Shoes select Nike Basketball suppliers like Sneaker Politics.
Being a sneakerhead means that you will inevitably miss out on some releases. The reasons can be varied: not living in the right Kyrie irving shoes area, limited edition runs, and pop up shops are all common moments of frustration in the hunt for your pair.Nike is warming up to the idea of the many different Jordan Basketball Shoes LeBron takedown models in his line being more widely available to people on this side of the world. If you have been keeping up with us here at WearTesters, then KD 8 you know that the overseas LeBron Ambassador VIII was reviewed here.That was an excellent shoe and there is a lot to like about the more minimal approach that the Swoosh LeBron 13 takes with LBJ’s takedown shoes. The LeBron Zoom Witness has also been featured here by Nightwing recently.If you were wanting to pick these up, they are now available at Finish Kobe 10 Line. This is a big deal if you don’t want to shell out for the signature models or cannot afford to. At $99, these are even cheaper than the Soldier Curry 2 line which is/has been the primary takedown model for much of James’ career.I have been steadily gathering Soldiers, from about the 3 onwards. They make for great all-around performers. (Still kevin durant shoes waiting on a good deal to try out the VII, I’m a bigger dude so I am hoping that fact will change how I experience the shoe.)This is pretty cool LeBron zoom soldier 9
