The way alien space ships travel is by diminishing the gravational pull of a host object and magnifying the gravitional pull of a far distant object. The acceleration would be immediate and the velocity would be virtually unlimited...once we can control the amount of gravitional pull exerted against and towards objects we will be able to travel anywhere in the universe and we will become accepted by the thousands- nay, tens of thousands- of distant lifeforms who have already conquered gravational forces.
Several alien cultures would be more than willing to help us with space travel, but we are considered to be primitive savages among the Celestial Union and as long as we refuse to disarm our nuclear arsinals and quit killing each other they won't share even a small crumb of their vast knowledge, such as a simple cure for genital warts. They look upon us with the same pity we might look upon a bananna slug being sprinkled with salt. It's facinating to see the foam, but My God, the inhumanity.
As world tensions rise we're visited less and less by space beings because the Galaxy is very succeptabe to a particular element of our nuclear arsinal, should, God forbid, we ever use them, and indeed there is a general feeling among the Celestial Union that it might even be in their best intrests to direct a couple of meteorites into Earth to take us out before we damage the entire Galaxy.
Thankfully beings so far advanced have abandoned Conservatism eons ago as being barbaric and cruel, and Liberalism...with its inherent values of goodness and compassion... is Universal, so the CU will leave it up to ourselves to determine our fate, but if launching nuclear weapons on Earth is imminent they will take us out first in self defense...but being good Liberals they will erect a monument somewhere (the Moon perhaps) attesting to the wasted potential of Earthlings, and their sorrow at our fate.
I personally have been abducted by alien spacecraft many times, and I've been in contact with two types of alien beings. My first abduction was at the hands of the Violators, as I called them, since they treated me like a lab rat and never spoke, prefering instead to probe my body cavities for hours on end, and these abductions occured almost nightly from the time I was 6 years old until I turned 14.
The Violators were very tall and wore "Caterpillar" ballcaps and smelled like beer. It was always dark when I was abducted and the examinations generally lasted all night. They ended when my Mom found out about these abductions and we moved to Wisconsin. The Violators were unable to ever locate me again, thank God.
Years later while harvesting peyote in the Sonora Desert of Mexico I had my first encounter with the Sillians. They were barely four feet tall, had slits for nostrils and large bald heads. They were dressed in silver jumpsuits, and appearantly were guided to my bonfire in the desert as I cleaned my peyote buttons.
My initial fear as they landed their large disc-shaped spaceship was put at ease by their telepathic assurances that they recognized me as a special being among Humans and thus worthy of Alien contact.
They gave me a tour of their ship, I gave them some peyote buttons and before long we were all holding hands, dancing around the campfire and singing, although I couldn't actually hear their voices as they only communicated telepathically.
The Sillians and I have had contact many times, and once I even piloted their spaceship after sharing several fifths of Crown Royal, and believe me, you thought cheat codes could make a plane do incredible things? That spaceship could dip and shimmy like a nine dollar artificial lure. One other thing I liked about the Sillians was that they thought my BB posts were funny and they never squelched me the way some backwards conservatives have.
Unfortunately I haven't been visited by the Sillians since my admittance into the Betty Ford Clinic, but I hope upon my release I can hook up with my old buddies from outer space and maybe we can fly down to Mexico in their spaceship, find some peyote buttons and drink lots of Crown Royal and dance around the campfire.
