Fine, but first let us examine the problems arising out of special relativity: For instance, why is the speed of light the sole factor that causes time to dilate and space to contract, what about radio-waves for instance? Do radio-waves also cause time to dilate and length to contract? Or take...

Thank you classical motion, this is exactly the argument that Nikolai Tesla used in his argument against Einstein: "I hold that space cannot be curved, for the simple reason that it can have no properties. It might as well be said that God has properties. He has not, but only attributes and...

Thank you Gibsense, what you say is true. The post has no real focus other than to illustrate what went into the foundations of modern Cosmology. What did people think of the Universe in the Sixteenth Century and how do those thoughts affect us today? The idea that 'matter' is an extension of...

Discovery of the Cosmic Microwave Background Radiation (CMBR) In 1964, Arno Penzias and Robert Wilson, working at Bell Labs in New Jersey, were testing a highly sensitive microwave antenna designed for satellite communications. They encountered an unexplained background noise that persisted no...

From the earliest times, humanity has turned its gaze to the heavens, searching for meaning in the vast celestial sphere. The ancients, through persistent observation, uncovered the regularity of planetary motions, leading to the profound idea of a cosmos governed by universal laws. This early...

Great! If you could explain what you mean by quantum, that would be a start.

Interesting theory, not least because it builds upon observed phenomena. Where does this leave neutrons? I also have (have had for many years) a new theory called "Augmented Newtonian Dynamics" or (AND) which at last seems to be enjoying a modicum of success. My story started a long time ago...

Surely, someone has a comment on this, imagine being able to derive gravity without using the Universal graviatational constant! Complete with worked examples.

Deriving gravity without the use of newton's Gravitational constant: Imagine being able to derive gravity without using Newton's gravitational constant or Einstein's 'kappa' which is a constant that relates space-time to energy and momentum? Sounds impossible? Augmented Newtonian Dynamics...

Helio, Thanks for your answer, even though I had wrongly attributed a quote as originating with you. As I look at the literature, it is apparent that there is a huge mass of data on this subject. But looking at a few articles on earth, which also has a partially liquid core, (although different...

I think it has something to do with the fact that radio waves or in fact ANY electromagnetic waves had the ability to carry energy. So the question was how can a wave, which is a diffuse object, carry energy? Mixed up with all this was Madame Curie's discover of radio-activity. :D Hope that...

There appears to be a basic dichotomy going on. The difference between the manner in which a solid and a liquid object spin, is part of human mythology, it has been used to tell apart boiled eggs from raw eggs for literally Millenia. Some particularly gifted persons can even tell apart well...

Here is a five year intensive study by Cornell University that shows that a partially liquid core plays a large role in (Mercury's) orbit. I agree that earth also has what could be considered to be a practically liquid core, but other factors are present that make it a more cohesive solid...

Many comments here are to the effect that it is only the mass that matters in calculating orbits and precession. But is this really true? In actual fact a solid sphere and a sphere filled or partially filled with liquid would rotate differently on their axis because the liquid inside the...

True, That is a lesson in itself. Never indulge in hyperbole when physics is involved and even though this is a discussion about physics and not physics itself, it seems that it still matters . Interesting to learn a more in depth history on this topic.
