Shuttles used to (or still do; please clarify this for me, too) use foam to protect the shuttle from aerodynamic forces and heat; did orbiters also use foam for this purpose?

Do they use the mean radius of the earth or the equatorial?

Either way, the altitude will never be the actual distance between satellite and sea level, due to oblateness and deviations of the geoid.

Is it just a falacy perpertraited by movies?

Also, if one where able to hold their breath in space without a suit, could u survive exposure to space for say a minute, then go back inside the ship and be relatively "ok" ??

Well we all know this is a very theoretical subject, and for the most part questions are hypothetical, but with that in mind here goes:


One of the points made by Einstein in relativity is that the mass of an object would increase as its speed increased. And as the object's speed approaches the speed of light (c) its mass approaches infinity. If its mass approaches infinity then so does the gravity associated with it.

So as you approach the speed of light you cover very large distances, but also the distance required to travel becomes less because your infinite mass and gravity bring your destination closer to you.

i know aristotle elaborated on eudoxus's explanations of outer space motion by increasing the number of spheres to 55. how did the idea begin? and how does the heliocentric spheres idea work?

1. Few_____ actually srick the Earth, beacuse most are small and burn up in the atomosphere.

2. The_____ ______ is a huge, sperical region at the outer edge of the solar system populated by many dark cold cometary nuclei, Sedna is the largest member of it found to date.

3. The_______ is the fuzzy spherical outgassing around the nucleus of a sun bound comet.

4. Most comets spent the majority of thier time beyond the orbit of Pluto yet many of thier orbits have _______ that are very close to the sun.

5. A _____ ________ is caused by an object (i.e. meteriod) interacting with the Earth's atmosphere and is proportional to the size of the object.

Thank you for helping.

Any simulation program for the n-body problem?

2007-02-22 05:49:07 · 1 answers · asked by Jano 5

My friend is doing their thesis on public opinion of space/space program and how it changed before and after going to space, focus on 50's - 85 or so. Any ideas on good sources, websites, new thoughts on the topic would be welcomed.

Thanks

Has anyone heard of it ? . As I understand it believers of this theory say that lights work not by emitting light but by sucking dark in. Dark exists as a thing, not just because there is no light , it is heavier and travels faster than light. Interesting theory but a bit hard to get the old head round. Perhaps blackholes in space are just really dark Suns radiating dark through the universe?

ok... many many many many people think light-speed cannot be achieved... but, i think they could be proven wrong by a simple 100 sq. foot black sail. "Solar wind" is what can help us achieve Light-Speed.

Explination: if we attach a black sail to one of our shuttles we use, and find a way to deploy it while we're in space, light will move the black sail... if you can find a way to steer the ship so that it doesn't just "go with the flow", then you have the ability to go where you want to... at the speed of light.

the only thing that is a downside is: The General Law of relativity.
for the traveler, it would be a few days of travel once at the speed of light... but if he's going to a destination that is 3-4 light-years away, it will seem like 3-4 years or decades to the ppl on earth... or possibly longer... which, by then, all our relatives would be dead or old... very sad. please give me ur input on this and i'll reply as best i can.
