Another Day in Paradise

Woke up this morning to find some people decided to go shopping in my garage and shed for multiple tools. To add insult to injury these fine folks decided to break into my truck, which they also tried to steal. I suspect they wanted my truck to haul more tools from my garage. I’ve decided to patrol my area during the wee hours when I find myself unable to sleep. These wonderful people better pray to their god that I never find them. I assure you, if I find them, they will need their god!

Computing PI to 130 000 000 000 decimal digits with y-cruncher..

In this video I tried (respectively my PC :) ) to calculate PI to 130 000 000 000 decimal places with a little tool called y-cruncher. Maybe it is not the new world record (12.1 trillion digits!), but I think it is for the first try already not bad :). The calculation took about 20 days (with interruptions and the the result was an 121 Gigabyte (Hexadecimal only 100 GB) *.txt file.”

Black holes warmed up space slower than previously thought

Black holes are big influencers for the early universe; these singularities that were close to ancient stars heated up gas and affected star formation across the cosmos. A new study, however, says that heating happened later than previously thought.

“It was previously believed that the heating occurred very early, but we discovered that this standard picture delicately depends on the precise energy with which the X-rays come out,” stated Rennan Barkana, a co-author of the paper who is an astronomer at Tel Aviv University.

“Taking into account up-to-date observations of nearby black-hole binaries changes the expectations for the history of cosmic heating. It results in a new prediction of an early time (when the universe was only 400 million years old) at which the sky was uniformly filled with radio waves emitted by the hydrogen gas.”

These so-called “black-hole binaries” are star pairs where the larger star exploded into a supernova and left behind a black hole. The strong gravity then yanked gas away from the stellar companion, emitting X-rays in the process. The radiation, as it flows across the universe, is cited as the factor behind gas heating in other parts of space.

Persuade me or prove to me that I am mistaken in thought or deed, and I will gladly change - for it is the truth I seek, and the truth never harmed anyone. Harm comes from persisting in error and clinging to ignorance.
