I would love to help you, but this is out of my league. Howerver if you come accross the informaintion on how to calculate some of the other information give certian information, i would link it if you could help me with my excel project

I am working on updating an Excel spreadsheet that I have used to create systems. Part of the file is dedicated to calculating the anything from mean orbital velocity and period to surface area and density. I would like some feed back and help converting the template to the newer 1.6 format and if t...

I would like to think that if we are able terraform Mars, then we would also have a way to generate a sizable magnetic field. That being said, for a long term plan (millions of years), it might be best to move Venus out of its orbit and move it into mars orbit (we can adjust earths orbit at the same...

Short answer is yes. Not so short, It depends on atmosphere conditions which goes in resistance from the atmosphere, also there will be a maximum speed at which you can push off the ground (jump) which will also limit how high you can jump.

This so makes me want to start working on my Blue Venus Parasol & Reflector (Mega Structures) viewtopic.php?f=6&t=11660&st=0&sk=t&sd=a if i can only figure out a way to make a faceted hexagonal dish

I made a mistake in my original assessment, the numbers would be correct if the star was twice as hot, not for two stars in a system. For all intents and purposes the "solar winds" strength can be equated to the temperature of the star(s), So... Delta Trianguli A is a G0V Star and has a su...

I havent tried this, but it might work. create a dummy object. center it on the star, then add the ring and shadowsquares as sub - objects. I believe that you can have multiple sub objects cast shadows

I am undecided on what lenghts to go to re surface detail - but this screenshot should help visualize the size of the Ringworld... Which is almost impossible to really grasp. In fact, the more i go into this, the clearer it becomes that even though the concept of a ringworld is fascinating, it is a...

Thats a loaded question. You can figure this out on your own just using some rule of thumbs. Know volume to radius (4:1) and energy fall off (1:4) Two Suns means that you need about 25% more protection at the same distance. (falloff is the square root of the distance) This means you need about twice...

Wow, now that's a Houdini trick.

My main problem here lies in the fact that I would have thought that the heat element would have been transferred throughout the universe at the same speed as the light. Thus, my confusion. I will be investigating this question only because I am very much interested in the answer. This is where the...

We all know that 10,000,000,000,000,000,000,000,000,000,000,000,000,0...

Let me see if I can answer this one. Usually when they bring up the phrase "13.7 billion years was not enough time for the temperature to be uniformly distributed in the Universe we see." they are usually referring to the heat death of the universe. This imply that all matter is uniformly ...

Well thanks very much for the explanation for the Brain-Dead. Still " fascinating ." Even the mandatory ? attraction of mass is very interesting in its own right. What an amazing Universe we live in. :wink: To quote a well-known television character here, " Row, row, row your boat, G...

Fridger

So the Anti-gravitation would still be the gravitation because the antiparticle is the Graviton itself correct?

I wonder if this means that they will/can change the mars semi-direct mission to fully refill the ship IIRC originally the idea was to carry all the hydrogen on the ship to mars, land the ship and then use the hydrogen and the CO2 in the mars atmosphere to create Methane and use that at the propella...

it is possible that an object on earth to not be attracted by earth, to make the weight = to 0? :D :D :D Its possible IF the fundamental partial the Graviton exists http://en.wikipedia.org/wiki/Graviton. This has not been proven to date, and is one of the reasons for the new CREN experiment. IF the...

What is it expanding into? That is a good question, and one that may be answered in the future. The only thing we know is that it is expanding. I guess one question that could be asked is, is the volume of space increase relative to the number of strings. As hard as it is to believe ,at the quantum...

I forgot about that. Thanks. To me this leads credence to the idea that there might be a lower limit to the degrees of freedom between strings. If this turns of to be true then universe as we know it, at any given point is not so infinite. BTW I screwed up on the equations, The equation then boils d...

Its been along time since I have thought along these lines, so I might be making a fundamental mistake in this argument. Anyway, Anyone who is familiar with planks constant, should know that theoretically anything smaller then a planks length would be so small that is would wink out of the universe ...
