You mean a probe, right, not a man. Because given present technology, a man would be baked before he got out of the solar system.

186,000 miles x 60 seconds x 60 minutes x 365 days. This is the distance light travels in one year. The nearest star is 4 light years away. So figure 8 total light years to get there and back. You would be dead. Also, the speed of light is a maximum you would only be able to go slower than light by a millisecond. We launched Voyager over 12 years ago and it finally out of our solar system. At our technology it would take about three years to get to Mars and back. And that does not include the time you would want to stay there.

One year. And the only technology you need is a couch and a tv remote.
There is a derviation of Special Relativity that provides that time and distance are equivalent. You probably have heard of the space time continuum. That's what they are talking about. According to this derivation, if you stay in one spot, your distance between when you sat down and when you got up will be c*t. If t is one year, you will have traveled one lightyear.

But, if you could get a spaceship to accelerate you continuously at 1 g -- the force of gravity -- you would be get to one lightyear beyond earth in roughly a year and a half. The trouble is that with existing technology, we can't do that type of acceleration long term (for more than a few minutes) without running out of fuel.

The nasa tried the fastest rocket ever which goes to 7 times the speed of sound which is equal roughly to 2,800 km/s
Speed goes at 300 000 km/s
Making the ratio, you see that 1 light year would be pretty long (take in consideration that the rocket went to this speed for a fraction of second, we can sustain that much speed). we could go 0.00093% of the speed of light.... So onelight year would take : 1071 years :(
An other way would be, when we are in a frictionless environment (space) we can continually accelerate with minimum thrust then reach greater speed. But others problemes arise (colisions) ...

Drew - your question incorporates an errors - "... the area that gentle travels in one gentle 3 hundred and sixty 5 days" - a lightyear is a distance no longer a time, so the question ought to study " ... to holiday one gentle 3 hundred and sixty 5 days". a gentle 3 hundred and sixty 5 days is (in around figures) 6 x 10^12 miles (6 million million miles, or 6 trillion miles). The quickest any area craft has travelled is approximately 60,000 mph, completed with the aid of employing a gravitational "slingshot" around Saturn & jupiter, sio if shall we get a spacecraft as much as that velocity (and often develop its velocity to counteract the gravitational pull of the sunlight as we left the image voltaic equipment it would take (6 x 10^12)/(6 x 10^4) hours = 10^8 hours; one 3 hundred and sixty 5 days = 8760 hours, so if we divide 10^8 with the aid of (8.seventy six x 10^3) we get 11, 415 years, and that's only a million gentle 3 hundred and sixty 5 days. probable no longer a stable theory to hold your breath.

1 light year is 9.4605284 × 10^15 meters.
If we assume we can send people out at around the same speed as the New Horizons probe that's going to Pluto, which moves around 28,000 miles per hour:
1 mile is approximately 1610 meters, so to travel 1 light year at that speed would take approximately 5.876 x 10^12 hours, which is approximately 6.7078 x 10^8 years...
In other words, we need to go faster. ;)

A light-year is the distance light travels in one year, moving at 186,000 miles per second.
1 year has 31536000 secs
1 light year = 31536000* 186000 = 5865696000000 miles
Fastest space craft speed 107,373 MPH
Hrs it takes to travel 1 light year = 54629152.58 hrs
days it takes to travel 1 light year 2276214.69 days
years it takes to travel 1 light year 6236.20 Years
So it is about 6236 years!!!!

if man can travel 1 light year, then unfortunately he would die..
