i know people can go to the moon, but will that ever be possible with the stars of the universe ?

Question

I always watch the stars outside at night through my windows in my room. And sometimes i feel that there is just something out there, that is just waiting to be found that will change the world in some way. thanks

Answer 1

Tough question...

Astronomical distances are sometimes measured in the length of time it would take a beam of light to travel between two points (see lightyear). Light in a vacuum travels 299,792,458 metres per second or 186,282 miles per second.

The distance from Earth to the Moon is 1.3 light-seconds. With current spacecraft propulsion technologies, a trip to the moon will typically take about three days. The distance from Earth to other planets in the solar system ranges from three light-minutes to about four light-hours. Depending on the planet and its alignment to Earth, for a typical unmanned spacecraft these trips will take from a few months to a little over a decade.

The nearest known star to the Sun is Proxima Centauri, which is 4.23 light-years away. The fastest outward-bound spacecraft yet sent, Voyager 1, has covered 1/600th of a light-year in 30 years and is currently moving at 1/18000 the speed of light. At that rate, a journey to Proxima Centauri would take 72,000 years. Of course, this mission was not specifically intended to travel fast to the stars, and current technology could do much better. The travel time could be reduced to a few millennia using lightsails, or to a century or less using nuclear pulse propulsion (Orion).

No current technology can propel a craft fast enough to reach other stars in a reasonable time. Current theories of physics indicate that it is impossible to travel faster than light, and suggest that if it were possible, it might also be possible to build a time machine using similar methods.

However, special relativity offers the possibility of shortening the apparent travel time: if a starship with sufficiently advanced engines could reach velocities approaching the speed of light, relativistic time dilation would make the voyage seem much shorter for the traveller. However, it would still take many years of elapsed time as viewed by the people remaining on Earth, and upon returning to Earth, the travellers would find that far more time had elapsed on Earth than had for them. (This effect is referred to as the twin paradox.)

General relativity offers the theoretical possibility that faster than light travel may be possible without violating fundamental laws of physics, for example, via wormholes, although it is still debated whether this is possible in the real world. Proposed mechanisms for faster than light travel within the theory of General Relativity require the existence of exotic matter.

There are a dozen different types of travel that could work here...

Generation ships, suspended animation, sub-light travel, faster than light travel...

It would just take up way too much room here...

Answer 2

It is not likely that we can ever visit even the nearest stars. Proxima Centauri, one of 3 in the Alpha Centauri system, is the nearest star to our sun at 25,000,000,000,000 miles or so away. At escape velocity, it'd take 106,448 years for a ship from Earth to reach Proxima Centauri. Matter cannot travel anywhere near the velocity of light, because it builds up inertia exponentially. One could burn the whole universe to power a ship and still never would reach light's speed.

Answer 3

The stars are very far away. The nearest is 4 light years which is about 24 trillion miles. The distances are taunting but I like to think that man's technology is in its infancy. Like in the days of Columbus when the Earth was thought to be flat, these distances are thought to be impassable, because of the sheer disdain for undertaking such a project. I would agree given our technology as it exists today, it would be impossible, if not laughable to even think of such things, but conditions change over time, and the impossible become possible.
I think as god created man, he meant for us to explore not just our own planet , but the universe as well.

Answer 4

Stars are incredibly far away, the closest being 93 million miles away. Supplies would lack before then most inevitably. Also, the burning ball of fusion would destroy you.

Answer 5

Every thing is possible my friend
Just give them the time to develop
