I want to do an honors project on anything that can have mathematics about the speed of light and how it is impossible for a spaceship to attain that speed, what would it do to a space ships.
Can you include some formula's proving its immposbile or anything?
Thank you I will give best answer to you

I heard that an asteroid,or whatever,is due to collide with Mars at the end of January.
Will we be able to see it with a small telescope?
Any information, please?

This is almost impossible I guess. But what if this did happen?

Describe what you would see if you stepped on a scale while traveling in your spaceship at a speed of 0.86c. Would your mass change with speed? How about your frame of reference? Contrast both these questions with what would be noticed by motionless observers? Explain your response.

I get that one side is true course, one is airspeed, and one is direction/strength of wind, but how do I figure out what angle to fly at?

Lets say NASA just saw an asteroid with a diameter of 1 mile. and it would hit earth in 3 days what would we do? how would NASA stop it from hitting earth?

Some, if not all of us have heard of the big bang.. the event that started the whole universe. Well it is said that the 4 fundamental forces (gravity, electromagnetic force, weak and strong nuclear force) were once combined and joined w/ extreme heat, exploded, and thats how the universe was born. Well if this is true, shouldn't we be able to reenact this event? We have all these forces present on earth so isn't it possible that this could be done?

help!!mathematicians...?

halley's comet has an elliptical orbit with the sun at 1 focus.its closest distance to the sun is about 9 x 10 to the seventh power, while farthest is about 5.34 x 10 to the ninth power..

A. FIND THE LENGTH of the major axis of halley's comet's orbit.

B. WHAT IS THE LENGTH of its minor axis

If the known laws of physics are correct, then the universe must be someplace, but where? My contention is that physics is extremely flawed and thus, can't be trusted to predict or calculate anything. How can one base all of science on fundamentally flawed priniciples?

From a"string theory" student - “The beauty and complexity of the mathematical calculations necessary to explore the extra dimensions of string theory lured a lot of our most brilliant and gifted students to work for many years only to find that they had invested their time unwisely. Rather than admit their mistake, some like Motl will do anything to keep this dogma a science. Something it has not been for a long time”.."Like a 50-year-old woman wearing way too much lipstick," jokes Robert B. Laughlin, a Nobel Prize-winning physicist at Stanford. "People have been changing string theory in wild ways because it has never worked.".."Superstringers have now created a culture in physics departments that is openly disdainful of experiments"says physicist Zlatko Tesanovic of Johns Hopkins University.."it's my impression that more and more physicists are starting to join Krauss as 'skeptical agnostics' about string theory," said mathematician Peter Woit of Columbia University.

if cosmic strings exist would they be composed of matter or are they a defect in space time?
also has anybody calculated their mass per given length?
and is it possible for then to have an event horizon?
and one last question... wouldn't all cosmic strings be loops? seems is they weren't they would evaporate from the tips?

did any body know i can see saturn jupitor mars with my meade etx 125 telescope with my series 5000 4.7 ultra wide angle before i have meade etx 90 with my series 5000 4.7 ultra wide angle but i never try to look on the sky i just used for land right now i got etx 125 but my series 5000 4.7 ultra wide angle is on the way i just order so if any body know if i can see alot alot of stuff up on the sky let me know thanks all and happy new years

Let say NASA built a space ship, assemble it in space, can water be use as propusion in a form of steam? It can be easily heated in space to form a steam, pls don't vent your steam on me tnx. ;-)

Ok, im doing a science project and this project is about making a brochure about a planet, im supposed to pretend im a travel agent. anyway, you have to have a theme for your planet such as a ski resort, beach resort, or racing. anything like that. well i was going to do a beach resort but i dont know if there is water on saturn. so the question is, is there any type of water on saturn such as lakes, oceans, or rivers? can anyone tell me please.

...and reverse it.
However, if there are objects/bodies beyond our viewing range, how can we be sure about precisely dating the Big Bang? (Hopefully this makes sense). In other words, if we're unsure of the size of the universe, how can we use the rate of expansion to determine age?

Also, is it assumed the rate of expansion is (and has always been) constant?

Thx.
