Do you think we'll ever leave our solar system?

Do hard-core Christians belive in aliens, and if they do, do they believe Jesus died for their sins too?

I don't think so. They think the center of the universe is Earth (not literally). If God created the universe just for humans why would he make any other lifeforms? I think aliens contradict the bible so they don't believe in them.

I'm a Christian and i believe in aliens. Why wouldnt God creat other life-forms besides us, i think that's just stupid.

He said hardcore christians. I have heard many christians that believe in aliens so i know some of them believe in them. I just know that some very hardcore christians think that aliens don't exist because God only created us. Sorry if insulted you, it wasn't intended, sometimes I generalize too much.

The only way I can see to leave the solar system is to catch a "boost" from the sun. But that's not possible. So I doubt we'll leave it within 1500 years.

The only reason I can see us leaving in the next few thousand years is finding a nearby (using "nearby" loosely) planet that is similar to Earth, and even that would take us a while to get around to. I think it's more likely that we shape Mars and Jupter's moons to our needs and live there for a while, then leave.

We still need to figure out how to keep astronauts from getting nuked during long-term long-range spaceflight. The guys who went to the moon were only gone a few days, the guys on space stations are protected by the magnetic field. Dudes travelling between planets are completely exposed to all kinds of cosmic and gamma radiation. That'll be a stepping stone.

If humanity is united under a kind of new Roman-type empire and focuses no small amount of resources on space exploration, I'm sure we could raise hell for light years around.

We have suicide bombers why not suicide astronauts. It's true the radiation and not to mention you hope that in a years travel in sleep you don't hit an asteroid.

Even if we do i doubt we will hear of them once they leave the solar system we lose connection to everyprobe as soon as it leaves. I think the magnetic feild of the sun and planets is a major way we use ot communicate and thats why. Not sure exactly how it works but thats a guess.

Also to mention the "hippie theory" (mybrother) It remins me i was talking to him about stargate. They have ships why not travel from galaxy to galaxy. He thinks the collected mass of a whole galaxy being pulled by anouther wile your in the middle would be to much presure. Possibly same with solar systems.

I don't belive it or we would have died from our own against andromina but a thought.

Gravity dimishes a lot over great distances. As an example, the Moon has as much upwards pull on you as does a pea twenty inches (I think) above your head.

Star Wars and Star Trek make it look so easy to build and have light speed engines.

I thought they didn't go the speed of light but just warped space.

Star Trek, they wrapped their ships in a shell of other-dimensional space, Star Wars, they just speed up and enter some other dimension.

I wish i could see the day when we have colonies on different planets. Though the Japanese do have plans to have a base on the moon around 2025.

How come a pea twenty inches above the sea doesn't mess with tides then?

I know that they are affected by the relative positioning of the Sun and Moon to the Earth, but if the pea has as much pull as the moon, why doesn't it affect things too?

Is it something to do with the fact that the moon exerts a force over an area much wider than the pea does?

Gravity affects larger things more. The moon exerts very little force on you, because you are very small. It exerts much more force on the ocean, because the ocean is very large.

Right, I think I understand that now.

Cheers.

the nearest solar system is far enough away that even radio waves would take years upon years to reach earth, thereby making it impossible to steer a probe. It would have to be entirely robotic. So we would likely have to somehow use wormhole technology or send people on a VERY VERY VERY LONG journey aboard a spacecraft. We are currently looking at things such as solar sails and suchh for sending probes to other star systems. The truth is that you should be happy to see a landing on another planet in your lifetime.
Maybe if we're really lucky there will be some sort of colony started on another planet, but I doubt we'll reach another star system in person. Maybe if we're really lucky we will get a probe there. Get some nifty pictures. The distances are just too massive, we would have to have a huge technological revolution. I give us a few more hundred years before intertellar travel becomes viable. Right now we're still using chemical engines as our main source of propellant. Given we do have a few other kinds that don't deplete so easily such as solar sails or ion something or another engines that work by catching solar winds or using a combination of magnetism, electricity, and ions to get the same "equal and opposite reaction" effect as a chemical rocket gets but much more efficiently, the only problem here being that these type engines can't be used for alot of maneuvering, they don't accelerate like chem rockets.
