Read through a Wiki entry on this class of weapon and yeah it's just a nuke. The article headline made it sound like it was some kind of gravity weapon. Which sounds like something from a sci if story.


Sorry for the false alarm.

It tricked me too.

So, not only does this bomb control gravity, but it uses subterfuge as well... frikken science.

I believe the answer is in the data.

I felt a great disturbance in the Torsion Field, as if millions of voices suddenly cried out in terror and were suddenly silenced. I fear something terrible has happened.

Scientists have learned that Pluto, once considered the ninth and outermost planet of the solar system, is bigger than thought, with a diameter of about 1,473 miles (2,370 km), some 50 miles (80 km) wider than previous predictions. Pluto is now officially bigger than Eris, one of hundreds of thousands of mini-planets and comet-like objects circling beyond Neptune in a region called the Kuiper Belt.

Hope this means the other planets wll stop pickin' on Pluto.

Science Friday had an interesting interview today with Kim Stanley Robinson about the challenges if interstellar travel... No linky for y'all, but you can track it down easily enough if curious...

...the challenges if interstellar travel...

According to a show I just saw on the Science channel, maybe we'll need both humans & robots.  They proposed that you could send frozen fertilized human eggs into space (much easier to do successfully than full adults), with robot "nannies" that would incubate and later raise them to adulthood as they reached their destination star system.  The question was, would these newborns really learn what it is to be human from nanny-bots?

Here's the show if anyone's interested.  Pretty good imho.

Today's test of the rocket engines for the Space Launch System, the rocket platform that is designed to someday put people on Mars.

I don't think there is any question but that they would not.  Look at the diversity of culture here on Earth, and that's all humans interacting.

New image of Earth:



Unlike most, this is not a composite, but a single image taken from a million miles away.  A satellite has been placed at the Lagrange point to take these images regularly and record changes in the Earth's climate.

Very cool, thanks for the link, PJ.  Sounds promising:  "The programme will be 50 times more sensitive than previous searches, and cover 10 times more of the sky ... It will scan at least five times more of the radio spectrum, and 100 times faster, while in tandem undertake the deepest and broadest-ever search for optical laser transmissions."

And it will be a waste of 100 million dollars.  Everyone knows type I+ civilizations communicate via subspace  ;D

I feel like this project will prove to be very important. If it will be 250000 times better than before, it kinda gets the spidey senses tingling.

Who knows, maybe they do it by Gilligan's Island reruns like us.   ;)

The satellite that gave us the image above now gave us one of the far side of the Moon.  You can even see the Sun reflecting off the ocean.  This thing is going to capture great unprecedented images of Earth that will be updated online daily.

I'm not sure if something like this has been posted before, but here is a little .gif of all the multi-planet systems discovered by Kepler as of the end of 2013.  Sorry it's so small!
