Cosmic recoil and cretaceous chickens

A couple of headlines from the world of science caught my attention this evening:

Huge black hole catapulted through space
Black hole exiting its home galaxy spotted for first time

A colossal black hole has been spotted exiting its home galaxy, kicked out after a huge cosmic merger took place. […] When two colliding galaxies finally merge, it is thought that the black holes at their cores may fuse together too. Astronomers have theorized that the resulting energy release could propel the new black hole from its parent galaxy out into space, but no one has found such an event.

Eventually, the black holes would fuse, and “in the final coalescence, or merger, of these two black holes, a giant burst of gravitational waves is emitted,” [Stefanie Komossa of the Max Planck Institute for Extraterrestrial Physics] said. “Since these waves are generally emitted in one preferred direction, the black hole is then kicked in the other direction.” […] The escaping black hole Komossa and her team observed was racing along at 5,900,000 mph.

Tyrannosaurus Rex Basically a Big Chicken
Tyrannosaurus rex just got a firm grip on the animal kingdom’s family tree, right next to chickens and ostriches.

New analyses of soft tissue from a T.rex leg bone re-confirm that birds are dinosaurs’ closest living relatives. “We determined that T. rex, in fact, grouped with birds – ostrich and chicken – better than any other organism that we studied,” said researcher John Asara of Beth Israel Deaconess Medical Center and Harvard Medical School. “We also show that it groups better with birds than [with] modern reptiles, such as alligators and green anole lizards.”

Scientists long suspected non-avian dinosaurs were most closely related to modern-day birds. This idea initially rested largely on similarities between the outward appearances of bird and dinosaur skeletons.

Evidently the recent evidence was gathered from a T.rex drumstick (seriously!). Read more…

    I think it is ironic (at least to me, as a YEC) that the second article tries to show the similarity to birds, based on T-Rex’s soft tissue, ultimately to try and show that birds and dinosaurs are connected via evolution. But wait! Soft tissue in a fossil over 65 million years old? And it hasn’t yet decayed?!? Please…

    And they say creationists believe in fairy tales 😉

  2. Steve says:

    Well Dave, just because you don’t know from this article how soft tissue could have been preserved, it does not mean or even imply that these scientists are believing in fairly tales. That’s not a valid argument – it’s an argument from ignorance and personal incredulity.

    What’s important is that this is actual chemical evidence that helps back up a claim made long ago by comparative anatomy. It demonstrates once again that evolutionary theory is good at making verifiable predictions.
