Well from my understanding, I believe earths scientist just don't have enough knowledge of particles to be able to create anti-gravity vehicles. Theoretically it would be possible to create a hover car without any rockets just by sending a positive charge to the earths core. This would create a magnetic effect where the positive charge from gravity against the positive charge of the vehicle would force the two to separate but of course, no scientist has been able to work out how to make such a charge identical to the charge of gravity. That is also where they loose when creating space shuttles for creating gravity systems because currently the space ship needs to rotate for artificial gravity.
So as for the original question I would say humans can master physics before humans become extinct and I would say the nearest life in the universe is in the Pegasus galaxy (Atlantis lol).

US knows of existence of aliens in solar system alone who are far superior than human species for sure , but I do now know why they want to keep this type of information secret.

The answer is distribution of the power and the balance. But the rather
than the power
there can be technologies that can make the life easy that can't the
directly applicable to the military applications. So I think it's fair to
release that these knowledge.

mean old u.s. always hiding the goods from the rest of the world.

you should meditate on over to the other side of the universe and bring back some super duper ubar technology.

that'll show 'em.

I know some technology the US government is hiding. A stargate that was found in egypt where the US government has been able to trade technologies with species from distant galaxies then they made a movie about it so nobody would suspect it.

Whoa! Someone's been listening to way too much Coast to Coast(not like I don't, since it's one of the few forms of entertainment for an insomniac like me).

I sometimes wonder where all the tinfoil hat folks are, then posts like this pop up. I hope that the OP is an ESL speaker cuz the grammar sure sux.

Do you understand the meaning of anti-gravity? Once you remove gravity from its effects on a body, you then have to worry about the Noether charge of translational invariance w/r/t momentum as a Lorentz vector (treating momentum as four-momentum in Einstein's Special Relativity).

Let me translate that for you - once you remove gravity, you do not float gently above the ground; your position relative to all gravity vectors is set to zero and you stop moving with the universe and the earth moves away from you at the speed of the rotation of the earth + the speed of the earth's revolution around the sun + the speed of solar systems speed around the galaxy + the rotational speed of the galaxy w/r/t the galactic super group. Heck, you might even hit the speed of light (in a relativistic way) but you sure won't live long enough to enjoy the trip.

no , not the way you explained now. thanks for explaining.
Interesting explanation GrimJack ,I think I got what you said.
you really awaken my dead interest on High eneargy physics.


I don't think that stargate is technically possible , because just the
computing power it needs far exceeds million times of world's most
powerfull supercomputer.and project blue book does not mention
anything about stargate.And Area 51 is incapable of doing these
experiments ( those are high eneargy physics experiments ) that
can be only done in places like CERN.

But it's fair enough to believe that anti gravity technology is there
and they are applying it on their fighters and war technologies.

about the anti gravity device ,the people who hacked it ,
have already published the white papers about how to
built and test a prototype of such device.so who can say no ?

I think the ppl like GrimJack can download that white papers
and make it at home. However it still needs to understand the
concepts of high energy physics to read that white paper
too.
