How to cancel out earth gravity.

If you pull hard enough (the force must exceed your weight plus the tension on your laces) you will rise and "hover" for a few seconds before falling over. Good balance is the key. Once you leave the ground it is like balancing a pencil on it's point so a couple of seconds is extremely good.

 

what does this mean? are you trying to say you can lift yourself up???

J.C.MacSwell is just joking on the topic "How to cancel out earth gravity".

 

There is no such thing or machine which is able to do that.

 

It is still possible to fly or have stuff levitating, with airplanes or like with this machine.

But it doesn't work by stopping gravity.

well yes, for the first few seconds, while you can use the ground to push off against.

Acrobats can get extra height by using the momentum of their legs in a flip.

 

the real problem is what do you push off against after that? (when you are airborne.)

 

most aircraft use the air itself.

 

rockets on the other hand, bring along their own material to push off against.

 

balloons use a slightly different trick with air.

Sure we can. A passive gravity shield would allow you to construct a perpetual motion device. So we can speculate (and really do motre than speculate) that it's not possible.

 

Which obviously means I was talking about an active one...

was replying to Bobeo' date=' your post was fine. :)

 

 

When did I say they worked in a Vacuum?

When did I even say they worked at all? ;)

What makes you think they need to work in a vacuum to be of use? :)[/quote']

 

The title of your thread is: "How to cancel out Earth gravity".

I can see how it could be confusing.

 

You really need to read the entire post and look at the two links and have some idea about electrostatics to get my intention.

 

I was hoping for feedback on the two links.
