Author | Topic: What is Gravity, how does it come about. | |||||||||||||||||||||||

You didn't answer my question. Take your time.
a rocket uses its propulsion against the resistance of the atmosphere and gravity to accelerate to E.V. Rockets push against the atmosphere? What kind of horseshit is that? [This message has been edited by crashfrog, 03-30-2004]

Are you familiar with the term Co-efficient of drag?
Your question... they would notice only subtle differences to do with environment, and 1G, strangely is not the same as the amount of gravitation they would feel on earth, similar but not the same.

Are you familiar with the term Co-efficient of drag? Are you familiar with Newton's laws of motion? Because you don't seem to be.
they would notice only subtle differences to do with environment What differences? The rocket is soundless and has no windows. There's nothing that can enter the rocket except for gravity.
1G, strangely is not the same as the amount of gravitation they would feel on earth, similar but not the same. It's exactly the same.

Yes.
No, it is not Gravity, it is inertia that holds them in place. No, 1G is less than the gravitation experienced on Earth.

What is deformed space?

No, it is not Gravity, it is inertia that holds them in place. You still haven't explained how you tell the difference. And your insistance on two separate forces that have exactly the same effect is becoming pretty comical.
No, 1G is less than the gravitation experienced on Earth. The gravity experienced on the Earth's surface (at some specific reference altitude, I'm sure) is exactly one G, because that's how a G is defined. You're trying to tell me that one isn't equal to one? By all means, keep talking. Maybe some sense will come out.

Let's see if your simple maths are as good as you make out.
1bar = 1atm... Yes or No.

Let's see if your simple maths are as good as you make out. Let's see if yours is, via multiple choice: 9.8 m per second per second is equal to: 1) 10 m per second per second 2) 8 m per second per second 3) 9.8 m per second per second There's no difference between the units used for gravity and the units used for acceleration - it's meters per second per second in each case. If you answered anything but 3, send back your diploma - you didn't earn it.

You never seem willing to answer questions, Why is that?
We'll make it 3 questions answered [even if not to your complete satisfaction] for 3 questions answered from you. What is deformed space? Is 1bar = to 1 atm.

You never seem willing to answer questions, Why is that? I'm happy to answer any relevant questions you care to ask, to the best of my limited knowledge. So far, few of your questions have been relevant.
What is deformed space? The presence of mass distorts space. Straight-line motion through warped space appears curved to observers in the universe. Duh.
Is 1bar = to 1 atm. Obviously not. But one atm = .987 bar. That's the same quantity expressed in different units. Ok, here's my three: Does 1 g = 1 g? How would you tell the difference between acelleration of one g and gravity of one g acting on a space capsule with otherwise no connection to the outside world? Why the fuck are you bringing up pressure in a discussion of gravity and acceleration?

The next thing is, are you aware of Einsteins micro-gravity effects on accelerating bodies [as in your example] and there absence with a resting body on the Earth...

You must have mis-read google... 1 bar is LESS than 1 Atmosphere... 14.5PSI against 14.7PSI Did you see my answer to why there is a difference between inertial G and gravitation? Einstein took us a good way... just not quite far enough. [This message has been edited by V-Bird, 03-30-2004]

Note that "your ass" is not a convincing citation. How would you detect these effects inside the space capsule? Assume that it's large enough to contain any equipment you like so long as none of the equipment penetrates the capsule.

Did you see my answer to why there is a difference between inertial G and gravitation? You mean your bullshit? I thought you were kidding. You're serious? Please, try again.

Space is 'nothing' yeah? ...how does it warp?
