I did some math to prove the flawed methodology of the drop test. The distance given for that test was 8.915m. A normal object would fall from that height in 1349ms.

So, let's take two objects for example. Because of human error, they are dropped 25ms apart. This is about 1/8 of the normal reaction time of humans. If the video camera is shooting 30 frames per second, the person dropping the balls would even seem to drop them at exactly the same time, because each frame is 33ms apart, with the exposure time depending on the shutterspeed of the camera.

In 1349ms...

The object dropped at t=0ms will fall the entire 8.915m.

The object dropped at t=25ms will fall only 8.589m.

This difference is 1.07 FEET. That is a large enough discrepancy to account for the difference in the video and be "proof" for the people that made the video to believe in this "effect."

Do you see why a drop test done by humans is not scientific evidence at all? They need to eliminate variables and retry the test. Plus, we don't know how many times they retried the test to get the desired result.

Remember guys, I'm a skeptic just like you guys - I'm just skeptical of the effect you're talking about. I'm perfectly open-minded to scientific, repeatable testing.

Lazerbeak, those aren't actual portals. They're just contours in the magnetic field. All it means is that if you travel from the earth to the sun on a specific path, the measured magnetic field doesn't change.

Gotcha Wolfman, thank you for clarifying that :beer: I just thought it was interesting that the Infra-red telescopes were able to reveal some previously unseen activity on the sun's surface and that NASA chose to use the term "portals" :)

Just food for thought, but in the very fact that we are able to, with our limited understanding of the universe, measure the speed of light and yet witness light unable to escape a black hole, suggests that there IS SOMETHING FASTER THAN LIGHT. And that is whatever force is responsible for the black hole in the first place. Gravity. There isn't even a need to argue that gravity is faster because it's already common knowledge that light cannot escape a black hole.
Good try, but that sounds like an infinite extrapolation of the facts :D
I'd love to hear what a physicist from CERN would make of that;)

Just to be clear, gravity moves at the speed of light, as I mention above.
And to build on what Wolfman29 is saying, the gravity exerted by a black hole (and all gravity, in fact) is due to the way the mass curves spacetime... not because gravity is "escaping."

Simple 2D illustration from Wikipedia:

The idea of Tachyons is certainly neat, but...

Despite theoretical arguments against the existence of faster-than-light particles, experiments have been conducted to search for them. No compelling evidence for their existence has been found.
That's not to say they don't exist, they just don't fit in the framework of known physics and we haven't found evidence of them yet.

They are probably one of those theoretical constructs that, according to a certain theory, are possible, but don't actually exist in this universe. White holes are another example.

Interested to see what new data comes out of CERN :thinking:

Also - I forgot to address Dave's remark on the god particle... it's not actually a god particle.... It's a misnomer. It was originally going to be called the "God Damn" particle, but they couldn't print that on the cover of the book.

Experiment B: When you bolt two magnets together when they repel each other, they fall at the same rate as anything else.

Explanation B: There is no outside force acting on the magnets, so they will fall at the exact same rate as a rock. The magnets are exerting great force on each other, but in Bushman's experiment there is no outside force that will cause the magnets to fall more slowly. The force present in the two-magnet system being dropped is akin to the force present in a system where two metal plates are bolted together and a bottle jack is placed between them and tensioned; it would fall at the same rate as a rock.


No matter the opposition of the magnets, Earth will still exert a force equal to the mass times the acceleration due to gravity. In the case of a magnet dropped down a pipe, an opposite force cancels some of the force due to Earth's gravity, causing the magnet to accelerate more slowly. In the case of two opposing magnets dropped from a height, there is no outside force and the magnets will accelerate and fall at the expected rate.

Magnetism and gravity are entirely independent.

Now all you need is the physical experiment to back these statements up.

Do you see why a drop test done by humans is not scientific evidence at all? They need to eliminate variables and retry the test. Plus, we don't know how many times they retried the test to get the desired result.

Remember guys, I'm a skeptic just like you guys - I'm just skeptical of the effect you're talking about. I'm perfectly open-minded to scientific, repeatable testing.

Well, I think in the end it comes down to having the money. I will agree no real conclusions can be made from that experiment, but it was interesting none the less. The height was not the same, as well as the strength of the magnets were no where near what Bushman used in his test. Actually I can't even imagine working with neodymiums costing 5k a piece, as magnets costing a fraction as much could easily crush through your body.

Magnetism and gravity are entirely independent.

If this is true why can they levitate plastic and any other material with large magnetic fields?

Here is an example -

Absolutely fascinating video! Thanks for sharing EC :beer:

~ LB
Thanks. I know this isn't anti-gravity, but it is interesting stuff. I would love to see a human being levitated inside the field. From what I read it is basically using diamagnetism producing a g field to over come earths gravity. From what I gather a lot of physicists say that gravity and magnetism are probably related but we just haven't come up with a unified theory linking them together.

Another approach to levitation could be based on what Townsend Brown did, using high voltage. A lot of people say it was just ion wind, but he did do the experiments inside a vacuum and it was said to perform even better. Paul Laviolette discusses it a bit in this interview here -
