Is it true that the moon can be seen from any part of the Great Wall of China?

Imagine if a black hole were to pop-up by or on Earth. Is there any possible defense? If you nuked it, the energy and matter from the bomb would simply be sucked into the black hole, right? Could it be contained? Extinguished?

Descriptions of gravity in texts are confusing to me because they describe the attaction between objects as though it was the the property of the objects.

We reject the concept of "action at a distance" (i.e. lifting your coffee cup with your mind) and yet we accept that the moon, 250k miles across a vacuum is able to drag the earth's oceans around. We calculate trajectories of space probes using the "gravity" of planets to accelerate rockets.

Models of gravity are equated with balls rolling round a vortex.

But space is a vacuum. Yes there are particles and "solar wind" but the theory of "aether" has been debunked. Planets and suns don't float in some soup that can be swirled by the passage of an object. Still, they seem to act as though they do.

Isn't gravity acceleration(s)? First, from the Big Bang and including all events since then, a genealogy of events (frictions).
Earth & moon each wiggling separately to a very old dance.

Would these be five different forms of energy?

1. Kinetic Energy
2. Mechnical Energy
3. Potential Energy
4. Thermal Energy
5. Work (Transfer of energy)

and how reliable are those predictions? How often do stars observable from our planet go supernova?

I believe in Evolution. However, in order to attempt to prove me wrong someone sent me an email that said the following:

"On the subject of evolution, scientific evidence proves that that is
not possible. The sun, for example,
40 million years ago would have been big enough to touch the earth.
Also, the earth is slowing in
rotation, so that means that it was going faster. What kind of life
do you think could have lived on a
planet that didn't have gravity to compensate for the rotation 40
million years ago? Everything on the
planet would have been flung off the earth. Those are just two facts
against evolution."

Are these facts true, or are they false and madeup. Please site your sources.

Einstein's equation, translated into English reads, to me:

Energy is created when matter is accelerated to the speed of light squared, or, energy is matter at the square of the spped of light.

A key point of relativity is that C is the absolute speed of a particle in our universe. (Experimentally, I assume that this means that no particle has ever been measured at higher than C. Of course, since the particles in the measuring device top out at C that would be difficult.) However, C squared. Can't happen. A science teacher once said that it was sufficient to us e=mv, or e=mc. So why an equation that contradicts the most fundamental point?

If our universe began as a singularity, that 'object' would be the densest matter imaginable. Assuming uniform expansion from a point (unlikely) for millions of years, wouldn't we "see" in that period a huge, dense, expanding, solid object? Wouldn't it take billions of years for the universe to thin out enough to create hydrogen?

Isn't it more likely, therefor that stars are not the result of 'congealing' hydrogen (or black holes) but rather of solids expanding to a stage where they "burst into flame"?

Could dark matter be matter that has not yet reached this level of "volatility?"

We study stars because we can see them. We are beginning to find evidence of planets. But most of the universe is made of "dark matter.' Does any testable evidence insist that it is a function of the Big Bang? Does it move in tandem with other celestial phenomena? Is background radiation any different in the presence of dark matter? Does it have any antimatter properties?

Now don't get started on "parallel dimensions." I mean simply that it is possible to imagine a "megauniverse" that includes but is not limited to the expanding matter available to our perception. (Since we are 'inside of" and "made of" our universe's matter we are, at present, limited by E.

[By 'universe' I mean simply an explosion of matter from a singularity into a vacuum. (Perhaps the vacuum surrounding the singularity has been 'vacuumed' of all matter by a gigantic black hole that resolves into the singularity.)]

However, there is no reason -not- to believe that our singularity might be one of many in various states of expansion or contraction. Hard to prove. We can't 'see' outside our universe. Still, could "dark matter' be evidence of interpenetrating universes? I'll ask that question elsewhere.

I know there was a site on the web at one time, with an auroral forecast. Not just a view of the earth, but a forecast showing when the northern lights would be most likely seen from certain cities.

Can anyone help? I can't find it. Just finding Alaska and Finland forecasts.

A few years ago, I saw something strange when I looked at the MIchigan night sky. It appeared that the stars were all moving in small circles. I saw a time lapse photograph of it the next day, but have since forgotten all of the information about what I observed. I am hoping that somebody on here either saw it as well or knows what I am talking about. The only thing information I remember about it is that it is an extremely rare occurrence.

I don't think so. Not that I claim to have seen any UFO's or been abducted. The line from the movie "Contact" says it all for me. "If we are alone in the universe - it seems an awful waste of space" I'm not sure if that is exact but you get my meaning. Any other thoughts?
