Why we should think ahead … way aheadIn order to see a difference with climate change, we need to look ahead and make a commitment to a future we will never see.
There are cathedrals that took generations to build — can you imagine starting to build something in the sure knowledge that neither you, nor even your friends or immediate family, would ever see it finished? These people lived in times of uncertainty — plagues, wars, shifting alliances, religious reform — and their average life expectancy was half ours, but their vision was vast. Today, we live longer, but have lost our connection with the future.

‘Invisibility Cloak’ Uses Transparent Carbon Nanotube Sheets | TPM Idea Lab

The incredible display is achieved by using transparent sheets of carbon nanotubes one-molecule thick, dunked in water. When the temperature of the sheets is increased rapidly by an electrical current, the sheet transfers the heat to the water in its immediate vicinity, causing light rays to bend away from the object behind it, rendering it invisible.

The device is being developed by  professor Ali Aliev and his research team at the Alan G. MacDiarmid NanoTech Institute at the University of Texas at Dallas.

my question is…

Can it be ready to use against Oklahoma Saturday?

end of the world questions answered

2012: Beginning of the End or Why the World Won’t End?

Remember the Y2K scare? It came and went without much of a whimper because of adequate planning and analysis of the situation. Impressive movie special effects aside, Dec. 21, 2012, won’t be the end of the world as we know. It will, however, be another winter solstice.

Much like Y2K, 2012 has been analyzed and the science of the end of the Earth thoroughly studied. Contrary to some of the common beliefs out there, the science behind the end of the world quickly unravels when pinned down to the 2012 timeline. Below, NASA Scientists answer several questions that we’re frequently asked regarding 2012.

Question (Q): Are there any threats to the Earth in 2012? Many Internet websites say the world will end in December 2012.

Answer (A): Nothing bad will happen to the Earth in 2012. Our planet has been getting along just fine for more than 4 billion years, and credible scientists worldwide know of no threat associated with 2012.

Q: What is the origin of the prediction that the world will end in 2012?

A: The story started with claims that Nibiru, a supposed planet discovered by the Sumerians, is headed toward Earth. This catastrophe was initially predicted for May 2003, but when nothing happened the doomsday date was moved forward to December 2012. Then these two fables were linked to the end of one of the cycles in the ancient Mayan calendar at the winter solstice in 2012 — hence the predicted doomsday date of December 21, 2012.

Q: Does the Mayan calendar end in December 2012?

A: Just as the calendar you have on your kitchen wall does not cease to exist after December 31, the Mayan calendar does not cease to exist on December 21, 2012. This date is the end of the Mayan long-count period but then — just as your calendar begins again on January 1 — another long-count period begins for the Mayan calendar.

Q: Could a phenomena occur where planets align in a way that impacts Earth?

A: There are no planetary alignments in the next few decades, Earth will not cross the galactic plane in 2012, and even if these alignments were to occur, their effects on the Earth would be negligible. Each December the Earth and sun align with the approximate center of the Milky Way Galaxy but that is an annual event of no consequence.

Q: Is there a planet or brown dwarf called Nibiru or Planet X or Eris that is approaching the Earth and threatening our planet with widespread destruction?

A: Nibiru and other stories about wayward planets are an Internet hoax. There is no factual basis for these claims. If Nibiru or Planet X were real and headed for an encounter with the Earth in 2012, astronomers would have been tracking it for at least the past decade, and it would be visible by now to the naked eye. Obviously, it does not exist. Eris is real, but it is a dwarf planet similar to Pluto that will remain in the outer solar system; the closest it can come to Earth is about 4 billion miles.

Q: What is the polar shift theory? Is it true that the earth’s crust does a 180-degree rotation around the core in a matter of days if not hours?

A: A reversal in the rotation of Earth is impossible. There are slow movements of the continents (for example Antarctica was near the equator hundreds of millions of years ago), but that is irrelevant to claims of reversal of the rotational poles. However, many of the disaster websites pull a bait-and-shift to fool people. They claim a relationship between the rotation and the magnetic polarity of Earth, which does change irregularly, with a magnetic reversal taking place every 400,000 years on average. As far as we know, such a magnetic reversal doesn’t cause any harm to life on Earth. A magnetic reversal is very unlikely to happen in the next few millennia, anyway.

Q: Is the Earth in danger of being hit by a meteor in 2012?

A: The Earth has always been subject to impacts by comets and asteroids, although big hits are very rare. The last big impact was 65 million years ago, and that led to the extinction of the dinosaurs. Today NASA astronomers are carrying out a survey called the Spaceguard Survey to find any large near-Earth asteroids long before they hit. We have already determined that there are no threatening asteroids as large as the one that killed the dinosaurs. All this work is done openly with the discoveries posted every day on the NASA NEO Program Office website, so you can see for yourself that nothing is predicted to hit in 2012.

Q: How do NASA scientists feel about claims of pending doomsday?

A: For any claims of disaster or dramatic changes in 2012, where is the science? Where is the evidence? There is none, and for all the fictional assertions, whether they are made in books, movies, documentaries or over the Internet, we cannot change that simple fact. There is no credible evidence for any of the assertions made in support of unusual events taking place in December 2012.

Q: Is there a danger from giant solar storms predicted for 2012?

A: Solar activity has a regular cycle, with peaks approximately every 11 years. Near these activity peaks, solar flares can cause some interruption of satellite communications, although engineers are learning how to build electronics that are protected against most solar storms. But there is no special risk associated with 2012. The next solar maximum will occur in the 2012-2014 time frame and is predicted to be an average solar cycle, no different than previous cycles throughout history.

14-billion-years-later:

Speed of light may have been brokenOkay guys, this one is hot off the press. I’ve only found two sources for this (here and here) that have been posted in the last hour. I have to say that I immediately doubt the validity of this, but I feel I should bring it to your attention anyway.Reports from our good friends at CERN say that they’ve observed particles traveling at faster than light speeds. For those of you who know a bit about relativity, this ain’t all that cool. The speed of light is basically meant to be the fastest speed there is, and if this wasn’t the case then we may have a major breakdown of Einstein’s theory of relativity.The scientists at CERN have concluded this based off results in which a beam of neutrinos fired from a particle accelerator in Geneva traveled 434 miles 60 nanoseconds faster than it should have. This may not sound like much, but the error was calculated at 10 nanoseconds and the scientists themselves seem fairly adamant in their results.

if the results can be proved…
this changes …
everything.
