In a new peer-reviewed paper in BIO-Complexity, Michael Denton challenges the view that biological organisms are accidents of random mutation and natural selection, instead adopting a structuralist view that body plans are like Platonic “types,” woven into the fabric of nature.
According to Denton, a biochemist and Senior Fellow with Discovery Institute’s Center for Science & Culture, this perspective, popular before Darwin wrote Origin of Species in 1859, “was not based, as Darwinists often claim, on a priori philosophical belief in Platonic concepts, but rather upon the empirical finding that a vast amount of biological complexity, including the deep homologies which define the taxa of the natural system, appears to be of an abstract, non-adaptive nature that is sometimes of a strikingly numerical and geometric character.”

For every particle there is a corresponding symmetric particle. Physics has a translational symmetry, which means that the laws and values of physics are the same at every location in the universe. If an observer were to travel from one point to a much farther distant point the observer we see no change in the physics. A broken symmetry introduces change—a non-absolute uniformity. The breaking of symmetries creates complexity in the laws of nature in the outcome of laws. There’s a symmetry and uniformity between the strong and weak nuclear forces, which have been unified as electromagnetism by James Clerk Maxwell. A typical example of vital symmetry breaking is that which gives rise to the balance between matter and antimatter in the early universe. However, there is an asymmetry between the quantum and the large (a la gravity). String theory is the attempt to unify all of physics.

In 1865 James Clerk Maxwell had unified electricity and magnetism by developing his equations of electromagnetism. It was soon realized that these equations supported wave-like solutions in a region free of electrical charges or currents, otherwise known as vacuums. Later experiments identified light as having electromagnetic properties and Maxwell’s equations predicted that light waves should propagate at a finite speed c (about 300,000 km/s). With his Newtonian ideas of absolute space and time firmly entrenched, most physicists thought that this speed was correct only in one special frame, absolute rest, and it was thought that electromagnetic waves were supported by an unseen medium called the ether, which is at rest in this frame.

My name is Chad Gross and I am the director of Truthbomb Apologetics. Brian Auten of Apologetics315 recommended that I email you with a question that I have.
My question deals with gravity and whether or not it is immaterial. It seems to me that gravity is not composed of matter and/or energy; therefore, it is immaterial. However, when interacting with an unbeliever on the topic on this post and he said the following:
“Without mass there would be no gravity, right? It’s true that gravity itself isn’t made of atoms, but you must admit that the material world is more than just particles. Einstein showed that matter and energy are equivalent and can transform into each other. When I talk about something being material, therefore, I’m thinking of both matter and energy.
It’s true again that gravity might not be a form of energy, since it’s just a force. Maybe gravity arises due to the nature of space and time. But without matter, there would be no space and time. So I think it’s uncontroversial to consider the physical forces to be “material.”
When I think of things that are not material, I’m thinking of spirit, or soul. God isn’t made of matter or energy, and God would still exist even without any matter or energy, right?”
Now, I realize gravity is not immaterial in the same way that moral judgments, mathematics, logic, etc. Here is my reply to him:

The findings are detailed in a paper to appear online in [the Feb. 28] issue of Astrophysical Journal Letters…
Astronomers have captured what may be the first-ever direct photograph of an alien planet in the process of forming around a nearby star.
The picture, which captured a giant alien planet as it is coming together, was snapped by the European Southern Observatory’s Very Large Telescope in Chile. It shows a faint blob embedded in a thick disk of gas and dust around the young star HD 100546. The object appears to be a baby gas giant planet, similar to Jupiter, forming from the disk’s material, scientists say.
“So far, planet formation has mostly been a topic tackled by computer simulations,” astronomer Sascha Quanz of ETH Zurich in Switzerland, leader of the research team, said in a statement. “If our discovery is indeed a forming planet, then for the first time scientists will be able to study the planet formation process and the interaction of a forming planet and its natal environment empirically at a very early stage.”
The star HD 100546, which lies 335 light-years from Earth, was already thought to host another giant planet that orbits it about six times farther out than the Earth is from the sun. The new potential planet lies even farther, about 10 times the distance of its sibling, at roughly 70 times the stretch between the Earth and sun. [Giant Planet In the Making Spotted? (Video)]

Reblogged from Irene Klotz with Yahoo News.
Scientists are still sorting out the details of last year’s discovery of the Higgs boson particle, but add up the numbers and it’s not looking good for the future of the universe, scientists said Monday [Feb. 18].
“If you use all the physics that we know now and you do what you think is a straightforward calculation, it’s bad news,” Joseph Lykken, a theoretical physicist with the Fermi National Accelerator Laboratory in Batavia, Illinois, told reporters.
Lykeen spoke before presenting his research at the American Association for the Advancement of Science meeting in Boston.
“It may be that the universe we live in is inherently unstable and at some point billions of years from now it’s all going to get wiped out,” said Lykken, who is also on the science team at Europe’s Large Hadron Collider, or LHC, the world’s largest and highest-energy particle accelerator.
