Starship Asterisk*

Why do stars in our neighborhood like our Sun go at velocities like 220 km/s and in similar orbital directions around the center of the galaxy? If a typical star is formed by the random gravitational collapse of an IMC what gives the new star the impetus to go in a certain predicted direction at su...

How can Gas and dust, be affected by gravity, from 28 thousand light years away? The real question is, in the context of everything we know about gravity, how could gas and dust not be affected by gravity? Gas and dust have mass, and everything with mass is affected by gravity. Nobody has ever foun...

Thanks for sharing that information that stars can form in various ways. I have not heard that explanation before but suspected that was the case. Then, I presume the stars in galaxial globular star clusters are consistently very old stars with very little higher metals. I believe astronomers call t...

An average of 0.13 cubic light year per star? Eight stars per cubic light year? Did I make a mistake? What's the density as we approach the center? Presumably they would rotate a common center of mass ... but that wouldn't yield a globe. Are they being attracted to (repelled from!) a center? Centra...

The criteria for a circular low inclination satellite orbit is that: (R/r) > (P/p) 2 [/b]where: R = the planet's orbit size r = the satellite's orbit size P = the planet's orbital period p = the satellite's orbital period ------------------------------------------ Neptune / Neso example: _R = 4,503...

Issac Asimov computed these forces for all the known major satellites in one of his astronomy books. It is certainly true for all major satellites. If the Earth is removed from the Earth-Moon system the Moon should remain in its same orbit around the Sun. Not EXACTLY the same orbit...but close If a...

The moon is the furthest known natural satellite of the earth The furthest known natural satellites of all of the gas giants share this same property that their orbital paths around the Sun are everywhere concave toward the Sun (although, just barely in the case of Saturn). I wish to have more deta...

I may be asking questions that cannot be answered in theory or by other means. After the very first stars were created and after the first massive stars exploded how long is it estimated that the resulting debris of gases and dust gathered to form the next set of stars that would be large enough to...

Why is the Moon's orbit held in its place by the Sun's gravity force and not the Earth's gravity force? In fact, the Moon is the only satellite whose parent planet's gravity does not hold it in orbit around itself. Because. Really, that's the answer. It's just a question of orbital mechanics. I'm n...

The Moon and Earth are in sychronise orbits with the Moon forming a wave motion because it has less mass. Compute the force of gravity between the Moon and Earth and the Moon and Sun. The force of gravity between the Sun and Moon is significantly greater. The orbital path of the Moon around the Sun...

The most materials for the Earth came from a period prior to 4.5 billion years. Subsequent impactors and comets of course came since that time. But these objects are made of materials that also come from Supernovae.

i didn't know that. is it mentioned any where or you are just asking about it? it looks so odd! if it's held in it's orbit by sun, why it move in that path around earth? and why it's period of orbiting it equal to earth's while they have different masses? The Moon and Earth are in sychronise orbits...

There are two schools of thought in galaxy formation (no, you can't escape it!). The first one I'll discuss is "stars came first" that a cluster of stars used their gravity to draw in more material and so set off galaxy formation. The central black hole simply sank there and absorbed more...

Very good, Wayne. You are just beginning to form a new hypothesis.

That's by no means out of the question. The early universe was a pretty dense and very energetic place but we think that part of the initial formation of galaxies was around black holes (the "black hole came first" hypothesis). While a supernova does cause giant molecular clouds to collap...

For talking purposes assume the non-exploding star is like the Sun and 60 Sun radii apart from the supernova star. That's difficult since a star like the Sun can never explode. For talking purposes I meant that the Sun is the non-exploding Star and is 60 solar radii away from the exploding star. Wh...

No idea on the average spacing, but population III stars were quite odd to anyone who has a vague understanding of the various fusion processes. A "normal" O or B class hydrogen fusing star uses the CNO cycle, a process involving catalysis by carbon, nitrogen and oxygen. However, these el...

"Obliteration" is a lot more difficult than you might think. You basically need to take every atom with in it and give them enough energy to defeat gravity and reach infinity: Gravitational binding energy. This can be estimated without scary mathematics by assuming an object is a uniforml...

"It is likely that there were other planets formed early in the development of the Solar System. This was a chaotic environment, with planets perturbing each other, transferring angular momentum, shifting orbital radii, changing position, and being flung out of the Solar System entirely. I thi...

Why did not other secondary planets occur at other Lagrangian points - especially Jupiter and Saturn? Why have not the asteriods at Jupiter's Lagrangian points been perturbed and collided with Jupiter? "The 60 degree fore and aft Lagrange points are stable only when the object in it is of insi...

Any impact hypothesis needs an origin for the impactor. This impact hypothesis proposes a secondary planet formed at one of the Earth's Lagrangian points and then collided with Earth. So questions do arise. Why did not other secondary planets occur at other Lagrangian points - especially Jupiter and...

Wayne, are you saying that there is no hypothesis for the nucleosyntheisis of Population III stars? Where eventually do the the heavier metals of carbon, nitrogen and oxygen come from? Do the rapid-fire explosions create these materials? The Big Bang theory does predict the timeline for the creation...
