Einstein’s general theory of relativity predicts that black holes exist and emit gravitational waves. Indirect evidence exists for these gravitational waves, but have thus far proved undetectable. All this may change in the next couple of years with new detectors that are highly sensitive to changes in gravity. Detectors are built based on computer models of what gravitational waves would look like. They basically measure the time taken for reflected laser light to travel down a vacuum tube, as this will be affected by gravitational waves. Projects such as the those at CERN and Fermilab will create the earphones needed to measure the forces of our universe. An interesting mathematical presentation on this idea can be found here.
Obviously this is a “real science” post to counter-balance the recent white hole theories...
At a special meeting about Dallas County traffic tickets, Commissioner John Wiley Price scolds Commissioner Kenneth Mayfield for the racist use of the term black hole.
Mayfiled uses the term black hole to refer to how paperwork commonly is lost within the office. Price demands that the office should be refered to as a “white hole”. It is interesting how some people believe that racisim needs to be announced in random venues to change technical and scientific terminology. This is the type of extreme over the top reactions which probably hurts Price’s overall cause and makes a mockery of politcal interaction within Dallas. Interactions like these cause the nation to stay away from the intense gravitational languidness of Dallas from which no intelligence is destined to escape.
Ah yes, but African Americans naturally cant’ be racist….as clearly seen in this follow-up video….
What color are the scientists?
Hmmmm maybe we should listen to one of them here and learn a bit about science and physics of the universe instead of blaming “whitey” for all scientific naming conventions.
Why does organic milk last longer than regular milk?
If you have been pouring over this question, Craig Baumrucker, a professor at Penn State University, has the answer for you. In Scientific American, Craig explains that the process to preserve organic milk is different than regular milk.
The process that gives the milk a longer shelf life is called ultrahigh temperature (UHT) processing or treatment, in which milk is heated to 280 degrees Fahrenheit (138 degrees Celsius) for two to four seconds, killing any bacteria in it.
So instead of crying over your early spoiled milk, try buying organic and it will last a bit longer than the regular pasteurized milk.
The Phoenix Martian lander is busy scooping soil. There are some white specks mixed in which could either be frozen water or salt. It could be a salty discovery…
Directly under where the arm meets the body, the rubblely surface reveals a flat smooth shape which could be ice. NASA has tempered expectation a bit by stating this could just be a smooth rock. Also NASA scientists state they think the salt content within the water would be too high for life to have any potential. Potential or not, the possible rock is cooking a bit of excitement.
