OK.... I give up trying to explain why travelling 600 light years or even 16 light years to the next known solar system is impossible.......
Even travelling to Jupiter is impossible not only because it's a big ball of gas and you would fly straight through it. its 400 million miles away.
Some people here don't seem to realise how far these places are and why they are simply impossible to get to.



Nothing lasts for ever. That's a fact of life that no human can ever control. Everything we see and love will one day be nothing but dust and we have to accept it.

In 66 years we went from the first human ever to create a powered flight and travel 100 feet to landing on the moon with a piece of metal less advanced then my cell phone. That's absolutely insane. In 30 years we'll have a supercomputer more capable than any human in every way and who the hell knows what happens from there.

The point is that saying things that require extremely advanced technology are "impossible" is ridiculous. Who knows if we will be limited by the perceived distance of 600 light years? If modern physics teaches us anything it's that we are constantly wrong and keep improving on our understanding of the world around us.

Again, I don't know if the answer is anti-matter, wormholes, a foldable universe, etc, but I know for sure that nobody else does, too. We'll just see where this unbelievable existence takes us.
Also, on an unrelated note, there's a pretty good chance the gas giants have small solid cores.
 
Scientists across the globe actually have a fantastic method for finding out if a planet is habitable or not. The take numerous photos of the planet as it passes in front of its sun.

Now if you've ever looked into the color spectrum of a rainbow, you'd know that it has some colors missing because our atmosphere filters out some of them. Certain gases omit certain colors.

The scientists can barely make out the colors in the atmosphere of that planet and then find out which colors aren't there. Thus, knowing which gases are present on the planet.

As for an efficient way of getting there, the collision of particles of matter and particles of anti-matter creates an explosion that physicists believe could propell spacecraftlong distances faster. It's the only reaction, that we know of, that is 100% efficient. 1Kg of this stuff could release an explosive force 10,000,000 (ten billion) times stronger than TNT. A single gram would get you as much energy as the fuel tanks of two dozen space shuttles.

Unfortunately, the amount of anti-matter needed to perform this kind of explosion couldn't be collected and kept intact for so long (it would take hundreds of millions of years to produce). Anther fault: the launch would exert up to 40 Gs of force upon the astronauts. Ouch.

For your wormhole theory, what you are thinking of is not a wormhole, it is "timetravel". Supposedly if you travel around a super massive black hole, such as the one in the center of our galaxy. If a ship that could withstand the speed, pressure, radiation and all that stuff at 90% the speed of light a kind of time travel starts to take place where some gravitational property messes with time so what is time outside of the ship is actually less time in the ship. This is ineffective because at 99% 1 unit of time inside the ship is equal to 2 units of time outside of the ship. It is in effective and dangerous as anything.

I really don't see why we don't invest in space travel anymore. I don't see why America can't put 10% of the 700 billion dollars that is Americas big swinging dick calls the army(and stuff), I don't see why they can't put some money toward the space program's. We should have a base on the moon. We should have the space elevator exist. We should actually make some real progress.

You know what would be cool? Is if some moss or lichen was created that did not need air to survive. They could survive on only sunlight, the nutrients in rocks so they could break it down and creat a type of soil, and would also use some compound in the atmosphere or rocks that have an oxygen element so it could be realised and make an atmosphere. They problem with that is what would be the buffer gas and what you keep the atmosphere sticking to the planet/moon. It would be cool to see the moon green because it's covered in a mossy organism.

Instead America (Obama) wastes those money on military,soildiers and other useless stuff that is use for war. And to worse of matters, euro's having a debt crisis now.

If the whole world were to work together as one nation, war can be prevented and no need for useless war machines.

Probably in the next millenia , Space travels like those in star wars will be invented. And are able to travel as fast as the speed of light.
 
you know, if humans can learn to terraform and colonize anything able to live on in space, or have space colonies, humans will be THE race, most likely. after all, what if keplar 22b is just a planet with single celled organisms? if we could engineer creatures to live on that planet you could engineer humans that way too, surely. we won't see it in our lifetimes, but if the human race doesn't kill themselves before we master space colonization, we will be the "aliens" we speak of now.
