Below is the abstract from Ben Nasmith’s paper “Classical Electrodynamics and Absolute Simultaneity”. I’m quite pleased to say that I was able to be an official endorser for Nasmith’s paper to arXiv. Please feel free to investigate and enjoy this research.
Maxwell’s equations and the Lorentz force density are expressed using an alternative simultaneity gauge. As a result, they describe electrodynamics for an observer travelling with a constant velocity through an isotropic medium.

The fundamental question raised by these postulates of special relativity is how different coordinate systems (reference frames) are related, i.e., how one transforms between them. (x, y, z, t) denotes the coordinates of some event in frame S, what are the coordinates (x’, y’, z’, t’) in the frame S’ moving at the velocity v relative to S? But first, a clarification on proper time and coordinate time:
Proper time is time measured between events by use of a single clock, where these events occur at the same place as the clock. It depends not only on the events but also on the motion of the clock between the events. An accelerated clock will measure a shorter proper time between two events than a non-accelerated (inertial) clock between the same events.

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:

Reblogged from Clara Moskowitz.
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)]
