"Curiosity" Driven Science

The engineers and technicians have done their job, and what a fantastic job they did! "Curiosity" is now on the surface of Mars and it's time for the science to begin.

Have you been wondering about the scientific mission? The search for life is getting all the publicity but, let's face it, the chances of success are slim.

What about the other missions? Rebecca Ghent of the Dept. of Earth Sciences at the University of Toronto explains why she's interested in the data that "Curiosity" will collect [Curiosity: planetary science and the latest Mars mission].

One of the things I'm interested in is the physical characteristics of planetary regoliths - the surface layer of broken rock, dust, etc., that covers planetary surfaces. It's important to understand how this layer formed and has evolved, because it holds a record of the geological processes that have occurred on each planet. Mars has a very complex surface geological record involving the actions of wind, volcanism, impact cratering, and possibly, water; so this new information about the composition and physical characteristics of the rocks at the Curiosity landing site will provide valuable new insights into the roles of these various processes in forming Mars' surface rocks.

For scientists, the best is yet to come. I hope the science journalists can keep the public focused on the real mission and the importance of the data.

Turn Right! Turn Left!

If you're driving on a two lane highway and a head-on collision seems imminent, you should turn right. This probably doesn't work in England.

Phil Plait of Bad Astronomy tells us that the Andromeda Galaxy is on a collision course with our Milky Way Galaxy [Hold on tight: in 4 billion years, we’re due for a galactic collision!]. What should we do? We don't know whether the Andromedons drive on the right side of the road or the left. Which way should we turn to avoid the collision?

Bacteria Fossils in Meteorites

When I first heard about the discovery of fossil bacteria in meteorites I immediately read the paper in the Journal of Cosmology [Fossils of Cyanobacteria in CI1 Carbonaceous Meteorites: Implications to Life on Comets, Europa, and Enceladus]. The first thing I noticed was that this "journal" seemed to be of very low quality. A little bit of digging revealed that it was some sort of online journal that publishes just about everything.

The second thing I noticed was that the evidence of fossils in these meteorites was not convincing. It seemed like the author, Richard B. Hoover, was not being very skeptical about what he was seeing. I dismissed the paper, it was almost certainly not true.

Lot's of other people reached the same conclusion.

Ian Musgrove at The Panda's Thumb [Life from Beyond Earth on a Meteorite, or Pareidolia?] [Commentaries posted at Journal of Cosmology]

Phil Plait at Bad Astronomy [Followup thoughts on the meteorite fossils claim]

PZ Myers at Pharyngula [Did scientists discover bacteria in meteorites?]

Rosie Redfield at RRResearch [Is this claim of bacteria in a meteorite any better than the 1996 one?]

The Journal of Cosmology has now published 21 commentaries on the paper and only two of them are the least bit critical or skeptical of the results. That inspired the journal to insert this statement in the introduction to the article.

Official Statement The Journal of Cosmology,
Have the Terrorists Won?
Only a few crackpots and charlatans have denounced the Hoover study. NASA's chief scientist was charged with unprofessional conduct for lying publicly about the Journal of Cosmology and the Hoover paper. The same crackpots, self-promoters, liars, and failures, are quoted repeatedly in the media. However, where is the evidence the Hoover study is not accurate?

Few legitimate scientists have come forward to contest Hoover's findings. Why is that? Because the evidence is solid.

But why have so few scientists come forward to attest to the validity? The answer is: They are afraid. They are terrified. And for good reason.

The status quo and their "hand puppets" will stop at nothing to crush debate about important scientific issues, and this includes slander, defamation, trade libel... they will ruin you. Three hundred years ago, they would burn you for questioning orthodoxy. Has anything changed?

The scientific community must march according to the tune whistled by those who control the funding. If you don't do as you are told, if you dare to ask the wrong questions, they will destroy you.

JOC offered the scientific community a unique opportunity to debate an important paper, but for the most part they have declined.

The message is: Be afraid. Be very afraid. Or you will be destroyed.

Why is America in decline?

Maybe the terrorists have won.

Did you need convincing that this is not real science?

Now here's the tough question. Why did so many people immediately see that this paper was flawed while many others, including some journalists, were taken in? I think it's because many of us recognized this as an extraordinary claim that required extraordinary evidence. We also realized that if this was even close to being true it would be published as a front page story in Science or Nature. In addition, we have lived through many examples of exaggerated claims, including previous claims of meteorite fossils that proved to be untrue; not to mention the 3.5 billion year old fossils that weren't fossils [Did Life Arise 3.5 Billion Years Ago?].

It's a combination of skepticism and experience. Can that be taught?

Astronomy and Biology

This is a remarkable picture. Depending on your personal preferences, you may be attracted to the sky in the background or the beautiful blue color along the shoreline of the lake. Are you an astronomer or a biologist, or both?

Phil took the picture and he explains it at: Gippsland Lakes.

Creation Astronomy

I'm sometimes accused of a bias against creationism and other forms of stupidity. So, in the interests of diversity and political correctness, I present one of the better examples of creationist logic.

This is from The 4th Day Alliance. Don't ever say that I haven't been fair to creationists. This is an accurate, unedited, copy of what's on their website (click on 'Start a Local Chapter"). I'm not making this up. I'm not quote mining.

We are in the midst of a major culture war and we need your help! As you know, one of the foundations upon which great negative change has taken place in our world is the false belief in evolution (naturalism).

While most people are familiar with Charles Darwin’s theory, few realize that an even greater fight is being waged in the area of astronomy. This is because evolution, as it pertains to astronomy, doesn’t just deal with the origin of life, but with the origin of EVERYTHING! If belief in evolution is defeated in the area of cosmology and astronomy, then other forms of evolutionary belief don’t have a leg to stand on. This is why evolutionary astronomers are some of the most dogmatic philosophers in existence today. Their ENTIRE WORLDVIEW rests on the foundation of evolutionary cosmology and astronomy. This is why evolutionists oftentimes feel most threatened by Creation Astronomy and wage the most virulent attacks against Creation Astronomers.

We are requesting your help to combat this problem on a grassroots level. Please consider this opportunity prayerfully.

There are literally hundreds of astronomy clubs around the country, but to our knowledge there is only ONE that is unapologetically Christian and that believes in the absolute truth of the Bible – the 4th Day Alliance. Astronomy clubs are responsible for teaching and introducing the public to astronomy. Unfortunately, 99.99% of the time they are teaching the myth of “billions of years” and false theories like the Big Bang.

Sometimes Violence Is Excusable

Here's Buzz Aldrin reacting to being called a coward and a liar. This is one of those times when I can't blame someone for throwing a punch.
