How would we move ourselves across the Galaxy in a spaceship?

Question

If Humans ever do discover another planet that we can live on how would we get thier in time without dying or running food and other supplies? anyone have any Ideas for Space ships like how they should be built? Should they farms and Animals on them?

Answer 1

The science for warp or hyper space is out there. It just has to be discovered or invented scientifically. Whatever the mind can conceive will eventually become reality. One day man will be able to travel the vast distances of space. That is of course if we don't blow ourselves to kingdom come first with these petty little wars.

Answer 2

That's the problem with space flight. It takes so darn long. Even in the show Star Trek, some voyages were just too long. Traveling at 100 times the speed of light (assuming you could) it would take 1000 years to cross the galaxy. At 1000 times the speed of light it would still take 100 years to cross the galaxy.

Suspended animation really wouldn't work because it's a one-way trip. It's not that people wouldn't volunteer for the trip, it's because friends or relatives left on earth would simply never hear from them again. They would have no idea of the success or failure of their trip.

A colony ship, where the people have families and the 3rd or 4th or 5th generation is who arrives at the destination is also questionable. How would we know that our children or grandchildren or great-grandchildren would agree with or want to have been included on such a trip? If things didn't go well, the ship could wind up over-populated with some people starving to death. Or it could also fall prey to some virus or other problem and not have enough people left to maintain a population.

As unlikelly as it might be, the answer would seem to be a worm hole. Even there the worm hole would have to be found, a method of travelling through it would have to be devised, and then we would be stuck with where ever it lead us to. We would probably have no control over the destination.

Answer 3

Before we can engage in interstellar travel we must come up with the requisite technology to create a spaceship capable of traversing great distances. Such a spacecraft would need a power plant that efficiently converts matter to energy. A matter/anti-matter engine which combines negative and positive protons would be the most likely candidate. In order to create "gravity" equal to that on earth, the craft would need to be able to maintain an acceleration of 9.81 meters per second squared for half the duration of the trip, followed by an equal deceleration for the remaining half. This rate of acceleration/deceleration will get the astronauts to another solar system within a very reasonable time due to the time dilation that they will experience. Unless they were traveling deep into the galaxy they wouldn't need to take a huge amount of food with them.

Answer 4

My guess is that Homo Sapiens will never leave our solar system. It would be quite a achievement to leave the planet. There is no better "spaceship" than planet earth.

If Einstein is correct about the speed of light, any spaceship approaching that speed would require immense amounts of energy. Also, there is no known propulsion system that does not require momentum transfer. That is for something to move forward, something has to move backwards. This means that you need to carry huge amounts of mass to "throw or expel" the other direction for you to go forward. It is true you could use gravity to sling shot you out of the solar system. But that isn't very fast (at least not that approaching the speed of light). In 1998, Voyager 1 became the most distant human-made object in space. It was going pretty fast. At that speed, it would take tens of thousands of years to reach the next closest star.

More likely is that humans would go extinct by destroying our spaceship earth with pollution. Or if we somehow pull it together and become outstanding stewards of this planet, eventually the earth itself will kill us with global change through increased vulcanism. That has happened 7 times before. When the earth spews out toxic gases for hundreds of thousands of years, you get major extinctions.

We survive at the mercy of spaceship earth.

Answer 5

By getting to another different galaxy without dying in the way, we'll either need stolen, borrowed, or gifted alien technology, or wait until the future for scientists to come up with faster-than-light space ships. Another solution is hibernation, but some people might die, but it's the best way to get there so far. And we should take animals and put them to hibernate too. We could also wait for the future to come up with a tele-transportation system. Then we'll be sent toward that place in another galaxy in almost no time. (You can try witchcraft if you want to.)

Answer 6

ahhh, the planet always looks greener on the other side of the galaxy! but a lot of the answers are right, that it would be monstrously difficult to get there by human made spacecraft; certainly not in the forseeable future.

but for the meantime, be happy: we're already on a spaceship--it's called Earth--and we are moving across the galaxy at an amazing speed, as the galaxy spins around its centre. (that is, we are moving around to a spot opposite the spot we're in now, more or less, but keeping the same relation to the other stars in the galaxy, again more or less.)

enjoy the ride! keep this planet green!

Answer 7

I often pondered on that. I figured I would get my bike and attach two acetylene tanks and three Oxygen tanks. Prepare the line thrust to the ballast er equipped with high velocity shanks coupled with booster arms and power booster thrust.
My cok pit will made of fiber glass and resin. I can use a seat belt from my old Pinto and my old CB radio for communication..
I will need someone to light my next launch. My First test launch this year put a big hole in Moms back yard and shattered the neighbors windows and that had to be paid from my College fund.. So I think I had to much thrust on the reversal struts.

Answer 8

Put the astronauts asleep and then suspend them in a very dense liquid, that doubles as protection and food. the ship should recycle energy that propels it so that it is continuously going faster. The human body should be able to withstand the speed since it is within the liquid cocoon. The ship should have ten hulls of overlapping liquid to solid material. It should sweep material from outer space to use as energy as well.

Answer 9

My guess is embryos...

Make a small spaceship with nano technology that will ship frozen embryos to a planet (After a probe found it be OK).

The nano technology will build the artificial womb and all that is needed to raise and educate the humans and start society.

This will enable the ship to be 99.99% engines to get maximal speed at relative low cost.

Answer 10

Ion propulsion drive is the latest technology being used.It has a slow rate of acceleration but it can remain for great periods of time enabling a craft to keep accelerating for years.But as far as travelling to other galaxies,I'm afraid we'll have to find a way to bend space or discover wormholes to travel through.

Answer 11

Our "Galaxy" is about 100,000 "lightyears" in diameter. Since light travels just above 186,000 miles per SECOND, there is no possible way of reaching another star-system outside our galaxy before you, and everyone else upon the Earth has died many year before. Let me give you an example. Our "nearest" star to our Galaxy is called "Alpha Centauri" or also known as "Proxima Centauri" It lays in the constellation of Centaurus in the Southern Hemishpere. The "distance" lf this NEAREST star is 4.34 lightyears. At lightspeed (186,300 mph) travelling for ONE year, we would find ourselves about 1/4 of the distance to this nearest star!! Alpha Centauri, being 4.34 lightyears from our Solar System, is about 25 TRILLION MILES away. This means that travelling AT THE SPEED OF LIGHT, it would require you nearly 41/2 YEARS to reach this NEAREST OF STARS. If you think about this for a moment, it may "stun" your mind into the great VASTNESS of stars within our OWN GALAXY!! Between galaxys, of which the Andromeda is our nearest, lies 2.2 MILLION lightyears distance. At light-speed, it would require you 2.2 MILLION years to reach our nearest known galaxy. So as you can see, it is absolutely IMPOSSIBLE my friend!!! So the answer to your question is this: You CANNOT "move" across our galaxy...not even at light-speed, without requiring thousands of life-times...if not "millions" of life-times. Get my drift??
