hey, i thought i disliked you but now i like you...it's weird you know, and like... complex, you know kinda like vanilla ice cream and chocolate ice cream at the same time and you can't tell which one you like the most, so you just eat it up at the same time

Curiosity Update

NASA's Mars rover Curiosity has photographed a shiny, metallic-looking object that bears a passing resemblance to a door handle or a hood ornament.

The Curiosity rover has not stumbled onto evidence of an ancient civilization that took the family van to Olympus Mons for vacation, however. The object is simply a rock that the wind has sculpted into an interesting shape, scientists said.

"The shiny surface suggests that this rock has a fine grain and is relatively hard," Curiosity scientists wrote Monday (Feb. 11) in an explainer blurb accompanying the image, which was taken on Jan. 30. "Hard, fine-grained rocks can be polished by the wind to form very smooth surfaces."

Similar "ventifacted" (wind-eroded) rocks can be found here on Earth, notably on the dry, gusty plains of Antarctica, they added.

The newfound rock is not the first shiny object Curiosity has photographed on the Red Planet.

PASADENA, Calif. -- NASA's Curiosity rover has, for the first time, used a drill carried at the end of its robotic arm to bore into a flat, veiny rock on Mars and collect a sample from its interior. This is the first time any robot has drilled into a rock to collect a sample on Mars.

The fresh hole, about 0.63 inch (1.6 centimeters) wide and 2.5 inches (6.4 centimeters) deep in a patch of fine-grained sedimentary bedrock, can be seen in images and other data Curiosity beamed to Earth Saturday. The rock is believed to hold evidence about long-gone wet environments. In pursuit of that evidence, the rover will use its laboratory instruments to analyze rock powder collected by the drill.

"The most advanced planetary robot ever designed is now a fully operating analytical laboratory on Mars," said John Grunsfeld, NASA associate administrator for the agency's Science Mission Directorate. "This is the biggest milestone accomplishment for the Curiosity team since the sky-crane landing last August, another proud day for America."

For the next several days, ground controllers will command the rover's arm to carry out a series of steps to process the sample, ultimately delivering portions to the instruments inside.

"We commanded the first full-depth drilling, and we believe we have collected sufficient material from the rock to meet our objectives of hardware cleaning and sample drop-off," said Avi Okon, drill cognizant engineer at NASA's Jet Propulsion Laboratory, Pasadena, Calif.

I honestly think it's a part the Curiosity put there in order to find it.

Is the Higgs boson a herald of the apocalypse? That's the suggestion behind a theory, developed more than 30 years ago, that is back in the headlines this week. According to physicists, the mass of the Higgs-like particle announced last summer supports the notion that our universe is teetering on the edge of stability, like a pencil balanced on its point.

"It may be that the universe we live in is inherently unstable," Joseph Lykken, of the Fermi National Accelerator Laboratory in Batavia, Illinois, said on Monday at a meeting of the American Association for the Advancement of Science. "At some point, billions of years from now, it's all going to be wiped out."

Physicists have been wringing their hands about this scenario since 1982, when theorists Michael Turner and Frank Wilczek published a paper about it in Nature, NBC News points out. The pair showed that the vacuum of space can be in different energy states, and it will be most stable at its lowest energy. Trouble arises if we're not there yet, and we're inhabiting a temporarily stable state that should ultimately collapse.

We think of a �vacuum� as being empty, but the trippy thing about space is that even vacuums have matter in them. The vacuum of space is filled with the Higgs field, which interacts with elementary particles, and gives rise to the Higgs particle. The vacuum of space can be in different energy states, but like all of nature, it is inclined towards the lowest energy state, where it will be the most stable. What we don�t know is which energy state our universe is in: is it high or low? What will it look like if it goes to a lower energy state?

I love their slogan/catch phrase.

i took a dinosaur elective course and made this phylogenetic tree (cladogram) which relates all the dinosaurs discussed together.

This is from a few years back so there is a possibility that the relationships may have changed.

How the fuck did I not see this thread sooner??

Some great links in here. Definitely gonna be nerding out for the next hour or 2.

I know. We're still probably decades away from realizing this, but it's great to see that there's some serious thought put into the possibility of a real warp drive.

Here's another link about a black hole spinning at nearly 90% of the speed of light:

Good work! I was about to post the black hole one myself. It's currently boggling my mind as to how it's rotating at that speed! And the 'warp drive' link is awesome. The idea of expanding and reducing space either side of an object is an old one, but never considered physically practical...... I hope the proof of concept research produces some positive results!

In the meantime, I'll start work on creating the United Federation of Planets.

Unfortunately most science stuff I've been looking into lately has been in video form.

I just finished watching


And it's amazed me. I really enjoy the style that obviously knows what it's talking about and is quick to point out the strength of the data and where the current limits of science are. Most of all it's good to understand things that affect everyone in great detail.

I found most interesting of all Sapolsky's explanation of why human beings have developed cognitive traits that lead to deliberately (for the rational humans) irrational behavior.


Here's a standalone one for anyone who's wondering whether that series is worth getting into.

And here's a nice 3d animated thing showing every single animal.

Matt just made Hal make me write this.

I was watching a BBC film called Before Big Bang. The mainstream theory now is: Big Bang created our universe but didn't create the beginning.

In other words, there are multiple universes or we are consequence of a previous major event that created the Big Bang. It's getting more and more complex, and i'm starting to think we will never answer to that question.

The more they think, the far they get from the answers. Fuck.
