In your views, will human be able to travel to around the distance of 5 light years in the outer space?

Only with a Generation Craft... or Crafts

Or really fast ones.

Earth takes 225 million years to orbit her 169 000 light year path around the centre of the Milky Way, so it takes about six and a half millennia to go five light years, so we have already travelled much further than that.

Yes, eventually people will go to the stars. You can't go faster than light, but due to time dilation of relativity, the astronaut might age only days or weeks. People on Earth would age about 5 years.

No.  The furthest Humans will ever go in space is the planet Mars.

Beyond that the distance is too great and the time involved would be too long.

There is a speed limit in space that can not be exceeded.

Our fastest space craft would take over 17,000 years to go just One Light Year.

A light-year is 9.5 trillion kilometers. By division, that means it's going to take Voyager 17,720 years to travel ONE light year. That's 80,000 years to reach Alpha Centauri, 4.5 light years away.

Let us assume that one can travel at the speed of light, or that one can travel through wormholes, and that the technology exists. For our astronaut to travel 5 light years  it would be a 5 year trip for him/her but here on earth thousands of years will have passed.  No one would know the astronaut's fate unless those who sent him/her on this journey trained the next generation in mission control. At some point in time even this would end and no one would know the astronaut's fate. Think of the Voyagers.  After their batteries die no one knows what will happen to them.

All you have to do to know whether this would be possible, just think what a distance of 5 light years is. It has a length of 50 trillion kilometers! You would be inside a space ship for 5 years and going at the speed of light to get to the planet which you think would be habitable (and if it weren't?). First of all, speeding at the velocity of light is not possible, according to scientific findings. But even if future technology could make this possible, the voyage itself would be unthinkable to achieve. Think of the food required, and other commodities you'd need for the several astronauts (or passengers, if you will) in the spaceship. And when the very first astronauts get there, what will they do? Just set a tent in a sort of a camping site? No, I can not imagine humans leaving our planet to go that far, but at the same time would be the closest location, to start a new civilization on another planet next to another star we hardly know of.

Do not forget our need of two important protections: the two shields, magnetic belts, and ozone layers. Oxygen at a 21% should also be present in the atmosphere for humans to breathe.

I suspect most scientists --and me -- despite an antipathy towards the use of the word ,never , would say that we will never travel to the stars.

That is , never travel  at ,or  beyond, the speed of light -- which would make your voyage , pointless .

Nope.

Why would we ever want to do that? That's a lot of cold, irradiated, hard vacuum to traverse and for what? To possibly see some dust, rocks, ice and craters? Plenty of that right here in our solar system, just in case we haven't seen enough of it already.

Rocket propulsion technology has been at a standstill for decades. It peaked long ago. People get confused. They think that just because microelectronics has advanced several orders of magnitude in the last half century then every other form of technology must have advanced too, and will keep doing it. Not so.

If we are very very lucky, after the collapse of global civilization, survivors will be able to travel around a distance of five miles or so on horseback, bicycle or steam train. But I wouldn't count on it.

no we cannot do that unelss we have the gravity bomb. when we have a sully funcional gravity bomb implanted to the earths core we cannot travel like we want to. help. LEE LUU DALLAS MULTI PASSS

• Nuclear fusion engines could get a ship up to a large fraction of the speed of light.
