Math descriptions Math describes any systematic system. It may or may not have anything to do with the universe (ours). There's plenty of math describing Flatland, e.g., which is like a sheet of paper with zero thickness. Does something with zero thickness exist? If so, it exists only in...

FermiLab & Earth They'll keep getting: "One day older And deeper in debt!"

Superstring gravity According to string theory, the gravitron is one of the string modes in which the negative mass caused by its vibration exactly cancels the huge energy/mass caused by its tension, and the shape of the vibration causes the gravitational effects between other particles...

Trillyuns and Trillyuns... More bumph. There are 100s of billions of galaxies at most recent best guess, not trillions.:rolleyes:

Multiverses, & friends Here is a nice summary, up-to-the-minute, almost, of multiverse theories. http://www.economist.com/science/displayStory.cfm?story_id=922202&CFID=509370&CFTOKEN=54686411 They are all rather speculative, but some are somewhat testable, and something of the sort may...

Hooey. What a load of. Matter is matter. C is C. Survival is survival. RTFB.

Particles, etc. Nanok & Crisp.. It gets even worse than that. There are no ultimate "particles". In QM all particles are instances of field effects; at base, only fields exist. To be crude, only twitches of space-time+ which persist and interact. So there are no ultimate billiard...

Rigid particles No. :D

Luminiferous Ether? Ever hear of Michaelson & Morley?

Parallels Banshee; I am quite familiar with parallel universe speculations...I've read quite a bit by Penrose and Wheeler. Here are some interesting links, too: http://naturalscience.com/ns/books/book02.html and http://kuoi.asui.uidaho.edu/~kamikaze/documents/many-worlds-faq.html...

Questions Fair comment. 1) Locating and specifying orbit, etc., is much easier than you think. A radio emitting planet would be a very clear, distinct point source. Computing orbits is well within the capacity of even a simple computer. The missile would have a receiver/sensor which would...

2 issues Black holes and Big Bangs are unrelated. Mass falling into a black hole is not converted to energy. Both energy and mass entering a black hold add to its mass. The Big Bang does not require that the matter/energy it generates does not "come from" somewhere. It is spontaneously...

Moving Spots of Light James R.... Exactly. And no information can be transferred between two points on the moon or, say, between two stars by having an illuminated spot swing between them. I don't know how fast the scan point on a CRT screen can move, but regardless of such "apparent"...

Brainpans Yep. What happens when you try to pour 1 qt. of concepts into a 1 c. brainpan? Overflow and massive spillage. :eek:

Powers No, Banshee. That's 10^16, not 10-16. That means 10,000,000,000,000,000 days. It's called scientific notation. It can also be expressed as 10E16, where E refers to "exponent". :)

Hidden sources Adjust your meds.

Qualifications Qualifications are only part of it. There is a fixation and compulsive verbal syndrome at work here, I think.

I agree Sort of. But read the novel; it's a fun read, and the technology explained in it is real, and only slightly ahead of our time (like Pioneer;) ). It ain't so hard to do.

Timing So, what were you doing 10^16 days ago? Give or take a couple.

Read and understand Read the whole thread, Banshee. The technology to produce a missile that moves at 92% of lightspeed is not much beyond present capabilities. I am just acting as "advocate" here for Pellegrino, Powell, and Asimov's analysis of Alien Behaviour. To keep it simple, anyone can...
