Martian life: stuck somewhere between inevitable biochemistry and quirky biology Charles H. Lineweaver School of Physics, University of New South Wales, Australian Centre for Astrobiology, Sydney, email: charley@bat.phys.unsw.edu.au If traces of life are found on Mars the question that needs to be asked is: How independent is this life from life on Earth? ... Are we related to trees? ... Will whatever traces we find of life on Mars be related to life on Earth. ... Mars and Earth are not independent. ...
Catastrophism : . ... During the late 18th and early 19th century, a German mineralogist, Abraham Gottlob Werner, proposed that all of the Earth's rocks were formed by rapid chemical precipitation from a "world ocean," which he then summarily disposed of in catastrophic fashion. Though not directed toward the genesis of landforms in any coherent fashion, his catastrophic philosophy of changes of the Earth had two major consequences of geomorphic significance. ... Thermal Plate Tectonics : . ...
... It appears that, billions of years after the big bang, following the formation of galaxies, some form of dark energy that is causing the expansion rate to accelerate overtook the Universe. ... The transition from big crunch to big bang automatically replenishes the Universe by creating new matter and radiation. ... By dispelling the myth that the big bang is a beginning of space and time, superstring theory opens up new possibilities for the cosmological history of the Universe. ...

... As these data span a large range in redshift, they are ideal for testing the validity of Type Ia supernova progenitor models with the distribution of expected \delay times," from progenitor star formation to SN Ia explosion, and the SN rates these models predict. Through a Bayesian maximum likelihood test, we determine which delay- time models best reproduce the redshift distribution of SNe Ia discovered in this survey. ... 1998) SD model. ... We tested two Gaussian delay time distribution models. ...
