space probes/gravity.

[fire_mat99]

Hi all I have some basic quations .

 

1 I read a report of news statation saying that space probes can

never leave are solar seytem there are strange phononma that slows

down anything tring to escape are solar seytem

 

2 What would happen if a comit came close to earth and affect the

orbit of the earth and cause the earth to spin out of the orbit and

spin out of are solar seytem in deep space and can NASA do anything

to stop this or some how cause the earth to go back to its orbit

 

3.For aviation we use pellpeller ,jet egine and rockets in the future

we may use Propulsion or antigravity how would this help aviation and

NASA and are NASA working on any Propulsion or antigravity.

 

 

Also can NASA make gravity or antigravity.

 

 

 

And gravity is a gravitational wave

There are some anomolous accelerations measured with Poineer 10 and 11, but nothing AFAIK that precludes material from leaving the solar system.

 

Any comet that has sufficient mass/angular momentum/kinetic energy to chuck us out of orbit is going to pretty much wipe out all life if it hits us, so that's not something to worry about. If there was some close approach that perturbed us, the answer is no, there's little to nothing we could do about it.

 

There is no antigravity.

 

According to General Relativity, there are gravity waves.

if it knocks us out by a close approach then its likely to be bigger than earth so we would have plenty of warning

[BigMoosie]

What good would plenty of warning be? Its bigger than the Earth so blowing it up is out of the question, and there is practically nothing that can be done about our own orbit. The only slight possiblility might be that we blow up our moon to modify our orbit enough to miss the comet but I doubt that is considerable.
