I would be more worried about the Andromeda–Milky Way collision http://en.wikipedia.org/wiki/Andromeda% ... _collision

Hungry, The "aerobraking" proposals I've seen don't actually use atmospheric braking. They brake against the magnetosphere and stellar wind of the destination star. That would be correct. If I remember correctly the numbers of atoms per cubic meter in the interstellar medium are one to tw...

Are you seriously entertaining the idea of aerobraking from a velocity that would make interstellar travel feasible? I can't really see this being done with a (physical) solar sail... ...but I have seen it proposed as an option for slowing down a Bussard Ramjet. You are not using the the sail to br...

For interstellar space travel the best bet would be to use lasers powered by the sun to push solar sail. In this respect you don't need to carry fuel with you except to break and that could be done in another system by some areo and gravity assisted breaking. There may some more exotic materials, ma...

There might be a better definition of what a black hole is on the quantum level. Fuzzball (string theory) http://en.wikipedia.org/wiki/Fuzzball_%28string_theory%29 In a nut shell it propose to solve the both the information paradox and the singularly problem by calming that for all intents and purpo...

Well +/- some tens of a percent we are only seeing 0.45% of all planets with in the green zone or close so for each planet spotted there is likely 215 more that were not observed because the aliment of the orbital plain.

OK I have a potential solution based upon my sudo physics of space travel. Basically it involves taking a chunk out of a neutron star and moving it to next to the dwarf star. The Question is what would happen to the original neutron star? Considering that a slip of a few mm results in a starquake th...

Yeah, I guess I have to go back to the drawling board for my would be story. I was looking for a micro black hole to to consume the outer envelope of a star, but its was like how do I get something that has enough mass and more importantly the surface area to consume the outer envelope of a star is ...

The smallest sustainable black hole need to be around 10^22 kg/m^3, any smaller then that and the decay would faster then the black hole would be able absorb do to background radiation. This also makes the size of the black hole about the about the thickness of a piece of paper. If such a small obje...

Too bad it will not last. It just looks freaking awesome

that might be it. ok not as stellar as i remember (pun intended) such an effect might be added at the same time as the HDR lighting as it looks like a good deal of graphics will be overhauled.

na is was a circle that would bounce across the screen that would distort the desktop. It might have been win 95. I don't remember. My point was that its not that resource intensive.

Funny thing is that windows 3.1 had a screen saver that would warp the background IIRC

One thing i would like to see implemented is gravitational lensing for massive objects like neutron stars. Due to relativistic light deflection more than half of the surface is visible. http://upload.wikimedia.org/wikipedia/commons/7/7e/Neutronstar_2Rs.png http://en.wikipedia.org/wiki/Neutron_stars

Second star to the right.

Nice.

I think I figured it out. I am using semi arbitrary numbers for a hook making and orbit in approximately 117 minutes. This will allow the skyhook to be exactly over the area it started at and compensating for the spin of the planet. This means that the center of mass sky hook would be needs to be ro...

I am sure that most of you have head of the Skyhook mega structure to loft object into orbit. I am trying to figure out for my planet, what the best version of it would be. Ideally the hook would only come down in say 2-10 locations on the planet. The number drop will ultimately be decided by the le...

OK now I feel foolish. :oops: Thanks BTW I guess while I has anyone found an orbital resonance for a 4 or 5 body system similar to the Io, Europa, Ganymede 1:2:4 connection. This connection is unique because its self stabilizing one of the few cases where it works. I have been fiddling with some num...

For my system it should be sufficient, I am not looking for hyper accurate, just more accurate then what I have now. My original system was to perfect, and ended up throwing out objects with in a few thousands years time. I am trying to figure out some of the mechanics and interactions between objec...
