Math, physics and science geeks: Feedback Needed!!!!

http://wp.me/pCBeL-1e">Gravity Control by means of Electromagnetic Field through Plasma at Ultra-low Pressure

Seems somebody is pushing along a paradigm shift.

Will one of you math heads look this over and tell me if it is remotely feasible? Also there's a schematic for making your own anti-gravity device with a fluorescent light and fixture on page 21.

1. Is this about those aluminum foil triangle things?

If so that was debunked on Mythbusters. It didn't work in a vacuum.

[TalkingDog]

15. Read the pdf please. Otherwise thank you for the non-feedback. nt

[tridim]

20. I tried, it doesn't load.

[The_Casual_Observer]

2. I'd immediately suspect fraud when I see "control of gravity"

Gravity remains a complete mystery. No one has made any progress on this.

[Winterblues]

4. Actually there are trains running today that hover above the tracks

Magnetic action but it does defy gravity...

[Greyhound]

7. Magnetism does not defy gravity, rather it overcomes it.

OTOH, I think this is a well-known technology with great potential, particularly in the area of mass transit.

8. doesn't defy gravity

the force of gravity on the train is exactly the same as it is on any train of that size. but F_electromagnetism > -F_gravity. so it hovers.

10. Kevin Garnett defies gravity

every time he leaps for a rebound. He never defeats gravity, though. He always comes back down.

[TalkingDog]

18. thank you for yet another incorrect non-answer

21. It's just another mechanism to oppose gravity. Not the same as the allegations in the OP

...

[The_Casual_Observer]

32. I don't think you get it. Nobody understands how gravity is " transmitted" or why

bodies attract, much less trying to change it. It's fundamental & a complete mystery.

[Orsino]

3. Smells like bullshit.

I can't tell whether this is mere mathematical masturbation, or a serious study. There don't seem to be any experimental results, though the .pdf is hard to read.

[EnviroBat]

5. I read that entire paper and realized...

Why I never became a physics major...

[TalkingDog]

19. lol Amen! nt

[Teaser]

6. warning signs

1) no primary research cited, only introductory texts.
2) quantization of mass is wrong. Planck mass is 2.17644(11)×10−8 kg, not 3.9x10-73. way way off.
3)is v a function of U? He integrates dp in equation 5, but only swaps out deltaU for dU. He hasn't told me that v is constant, so that integral is not justified.

A few early problems. I'll read in detail later.

11. Don't bother. Old crank....

[TalkingDog]

23. Are you saying the pdf is on this page?

I couldn't find it.

[BlooInBloo]

24. No, I'm saying the paper's author is a known crackpot from way back....

[TalkingDog]

27. Ah, thank you. That is definitely helpful. nt

[positrac]

26. It's a link or 2 beyond...here it is

[positrac]

14. Also, after arriving at eq. 20, he proposes a completely unwarranted 'therefore'

...

[TalkingDog]

22. thank you. your feed back wins the gold star. Thanks. n/t

[BlooInBloo]

9. I should write a book: "Cranks and the people who believe them".

[NNN0LHI]

12. I can make popcorn with my cellphone

No, really ...

16. So what, I can turn wine into water

:D

[positrac]

13. It's not gravity 'control', it's gravity opposition. An airplane does -that-.

The problem with his exercise (even assuming the math is correct, I'm not inclined to redo all those calcs but a cursory glance seems to confirm it in general terms) is that (unless we have totally and completely misapprehended what gravity actually IS) it can't be 'blocked' or 'shielded' without uncurving space. Gravity can't be blocked by any material or apparatus since it distorts space and anything inside that space is equally distorted omnidimensionally equally.

17. The earth is attracted to Chuck Norris

[TalkingDog]

25. chuck norris has a fist hidden inside his beard. n/t

[BlooInBloo]

34. Chuck Norris doesn't get wet. Water gets Chuck Norris.

28. Electronic Cavorite

H.G. Wells started this quite a long time ago, albeit without the electronics.

Here at work I don't have a lot of time to find holes in the document right now, although I agree with the upthread poster about some of the problems. The one that jumped out at me is the author's dependence on inertia altering as a function of gravity.

[thereismore]

29. Bullshit. Take it from a physics PhD. nt

[JHB]

30. When the "Theory" section starts off with "it was shown" in an unpublished paper by the same guy...

...it's usually a bad sign. And when it continues throughout the paper, and all other references are either on technical matters or old textbooks and handbooks, it's an even worse sign.

A little Googling will turn up the author's website (Prof. Fran de Auino of Maranho State Univ., Brazil). He claims to have obtained a Quantum Theory of Gravity, which would be a capital letters Major Development in Science if it were true. Apparently he hasn't been convincing to other scientists in the relevant fields.

Since this paper is based on that, don't hold your breath waiting for a breakthrough.

31. Link is broken. Takes me to a blank page.

[pansypoo53219]

33. E=MC squared.

all else has been erased from my data base.

[Teaser]

35. and that's actually one of relativity's least central results

.

36. Bad link and NO./
