The rare double pulsar PSR J0737-3039

Is currently the only known double pulsar, it consists of two neutron stars emitting electromagnetic waves in the radio wavelength in a relativistic binary system. The two Pulsars are known as PSR J0737-3039A and PSR J0737-3039B. It was discovered in 2003 at Australia’s Parkes Observatory by an international team led by the radio astronomer Marta Burgay during a high-latitude pulsar survey

The double pulsar system PSR J0737-3039 is being studied in order to test out Einstein’s General Theory of Relativity put forward in 1915. The investigation of double pulsars is a great opportunity as the environment created by warped space-time due to the shift of intense masses is extremely rare, and thus perfect for the testing of Einstein’s theory and the observation of theoretical Gravitational Waves

    vruz: in my view of physics, that question doesn’t make sense. it’s like folding paper to make an origami dog and asking where did the dog come from.  where was the dog before?  was the dog barking before he manifested itself in our physical world?

Michael Shermer science skepticism

A QUOTE

In the meantime, in answer to the question Why is there something instead of nothing?, it is okay to say “I don’t know” and keep searching. There is no need to turn to supernatural answers just to fulfill an emotional need for certainty and comfort. Science’s uncertainty is its greatest strength. We should embrace it.

One can’t prove that God doesn’t exist, but science makes God unnecessary.

vruz: I take the opportunity to advise people that this guy just won a $10 bet, when he said that the Higgs boson didn’t exist. Apparently, according to recent studies, he also won the argument against emergent gravity proposed by Erik Verlinde.

it means nothing, of course, but at least I would personally place my bets more carefully.

Republicans: The Anti-Science Party

by Paul Krugman, guardian.co.uk / The Observer

[…] Jon Huntsman Jr, a former Utah governor and ambassador to China, isn’t a serious contender for the Republican presidential nomination. And that’s too bad, because Mr Hunstman has been willing to say the unsayable about the Republican party in the United States, namely, that it is becoming the “anti-science party”. This is an enormously important development. And it should terrify us.

To see what Mr Huntsman means, consider recent statements by the two men who actually are serious contenders for the Republican nomination: Rick Perry and Mitt Romney.

Mr Perry, the governor of Texas, recently made headlines by dismissing evolution as “just a theory”, one that has “got some gaps in it”, an observation that will come as news to the vast majority of biologists. But what really got people’s attention was what he said about climate change: “I think there are a substantial number of scientists who have manipulated data so that they will have dollars rolling into their projects. And I think we are seeing almost weekly, or even daily, scientists are coming forward and questioning the original idea that man-made global warming is what is causing the climate to change.”

That’s a remarkable statement – or maybe the right adjective is “vile”.

The second part of Mr Perry’s statement is, as it happens, just false: the scientific consensus about man-made global warming – which includes 97% to 98% of researchers in the field, according to the National Academy of Sciences – is getting stronger, not weaker, as the evidence for climate change just keeps mounting.”

vruz: I think this is a smart way of framing the discussion. I don’t think too many independents are anti-science, and the vast majority who vote republican aren’t anti-science. it’s also honest, now the democrats are the actual conservative party in many aspects, and the republican party is a theocratic authoritarian clan in all of them.

Well done, Obama administration! I guess James Hansen is a firebagger too?   d.i.s.g.r.a.c.e.f.u.l. ,  s.e.r.v.i.l.e.

James Hansen, head of NASA’s Goddard Institute for Space Studies, was arrested yesterday as part of the ongoing protests against the construction of the Keystone XL pipeline.

That’s what I call putting your money where your scientific mouth is.

God speed. Leave it to this country to either shut the scientists up or put them in jail in favor of company. I’m surprised not as much people are raging over this.
