@TheLucidor no, i'll believe you on the distance. what would be REALLY COOOL, would be if you had a video showing the star getting bigger and bigger as you approach it over that same period of time, like in the video, whether it's the fast forwarded time you drove or in the real time you drove. if i could watch a video of that, that'd really be cool.
@TheLucidor it's not the car that's the concern, the concern is was it the mileage driven or how far you actually drove. you didn't drive in a straight line, you went through streets and turns, so you didn't travel as far as you would have had it been a straight line, so was it the mileage or the actual distance away?
erm... I don't know how to break this to you...but you left your baseball (sun) on the pavement 50 km back..... d'ya think its worth going back to get it?
The bugs on the windshield are comets, Kupier belt objects, and Oort cloud objects.
Cosmologists suspect that millions if not more Kupier belt objects are so loosely bound to the sun that at least 100's of thousands, possibly millions, have been ejected and are wandering around between stars. That is just from our star.
Maybe this is just wishful thinking, but I believe that one day, perhaps thousands if not, millions of years from now, our technology will be so advanced that we can manipulate wormholes and space-time itself to travel vast distances. Of course, if we don't blow ourselves up first due to conflicting religions and ideologies...
Maybe not even that long. Look at how long it took mankind to get to the moon from the invention of the rocket in the 1920's. 50 years later we went to the moon.
All the nanoscale, picoscale, and femtoscale engineering in the world isn't going to change that. Hell, not even total conversion or reactionless drives would make that possible.
Even when an object reaches 100% the speed of light, it's own mass becomes infinite.
Unless you can create some kind of godlike contracted space-time metric around a craft using exotic matter (which doesn't exist) all of these scifi dream drives are bs
@jasonrroberts099 Maybe a better understanding of the field the creates gravity is needed before we can overcome it. If we could manipulate that field then why would FTL be impossible.
With our current understanding, we cannot theories a way to overcome it, but there is ALOT we do not know.
Um, except tachyons, and possibly other things we have not yet discovered.

The other posts are supposing that we figure out a way to travel outside of our spacetime, or pass through the speed of light outside our spacetime. The barrier is traveling AT the speed of light. It becomes increasingly difficult to accelerate as one approaches Light Speed. Logic suggests that for faster objects it's equally difficult to slow to the speed of light.
@jasonrroberts099 oddly enough rodenberry knew that when he wrote star trek... which is why in his sci-fi story the 'warp factor' was actaully a representation of how much the fabric of space and time was 'bent' around the traveling spececraft... basically the ship stood relatively still...and spacetime was bent around it...
Which is bollox I know... I'm aware of that... but its a lot better than 'faster than light' crap.
@MumblingMickey This bending of space/time is so much fantasy dreamed up by science fiction writers to get a space ship from point A to point B. However there are things going faster than light.. Yes, the galaxies furthest away from us are receding at faster than light speed. So it seems faster than light speeds are possible given enough energy.
@125RTY Erm.. nope thats incorrect...there are no galaxies speeding away at anywhere near light speed. I have no idea where you got that idea.
Next the bending of space time is a key principle of special relativity. As a physicist I could explain it to you but I doubt since you think matter can exceed the speed of light without transforming into electromagnetic energy that you'd get it.
I think you should read a science book (preferably one on basic physics) and lay off the Sci Fi!
All matter in the universe takes up space. An object in space (say a planet) not only takes up the volume of space it contains...but it also bends that space in three dimensions, a little like a steel ball on a rubber mat.
The heavier (more massive) an object is. the bigger the dent it makes in space. An object close to that 'dent' is attracted to it. We call that property 'gravity' and the dent is called a 'well'
Now what was explained and demonstrated using relativity was that since the dent actually stretches space.... then it now takes longer for things to traverse the well. All matter, all energy now takes longer to go around or past the gravity well.
If something is truly massive. like a quasar... then light traverses it, and is bent as it passes the well. This is referred to as a gravity lens.
It explains how we can see objects directly behind some stars.
However if light is taking longer to traverse the same distance then obviously time and space are in fact related.. They are spacetime...
Spacetime is a measurement of the space and thus how time is affected within it from the point of view of an observer outside it, compared to that on and observer inside it!
Applications of this include GPS satellites which compensate for the dent made by the earth in spacetime when the satellite (being less massive) does not create such a dent.
This is just insane, how can we ever hope to make direct contact with other civilizations when it takes multiple lifetimes over for light to even get there...?
@FountainDew85 For the most part we can't. Which might explain why so many of us think its a total waste of time and money.
Scientists who engage in these SETI projects are either desperate or can't hack it in the real world looking for real grants to do real work if you ask me.
Even if we found an alien message so what? the civilization is probably long dead... it doesn't give any real answers to anyone except perhaps biologists!
Plus it'd only serve to piss off the religious nuts even more.
@hellomate639 What you are talking about there is the technological singularity... and yep... its on its way... you and I might get to live in that world... the first time in the earths history there will be an intelligence greater than our own... creepy.
I think this is a very good way of actually getting the sense of scale right. It is so difficult to comprehend what a number like that actually means. If the Sun were scaled to a 1 foot radius, then Alpha Centauri would be about 10,300 miles away.
Considering the distance may be the equivalent, the car takes many turns, and makes many stops, that it only seems very far away by watching the video.
You aren't driving in a straight line at all. Good try though.
@Jasexxxxx Agreed... if he had started by using a grain of sand as the sun...then he might have been able to stand where he was and pissed on alpha centauri!
Assuming he was absolutely bursting for a jimmy riddle!
But it is possible, because if youre travelling at near the speed of light, time in the universe around you slows down, so you could travel 20 light years in 6 months. However, when you came back to earth your kids would be older than you... but thats a different story altogether
I never understood the massive distance in our solar system, until 10th grade when in astronomy class we made a scale model out of a reem of paper you fould find in a cash register for recepits. I think it was 1mm=1million miles. the inner planets were all bunhced up and the outer planets were many feet apart.
@JeffAdkins Yet you were going TONS faster than the speed of light, yet it took you A VERY LONG TIME to get there. Damn that's far. I can only imagine how much closer and brighter the nearest star would look after one full light year. so, then, counting all driving as strictly linear motion, not counting curves on getting there, is that odemeter distance 100% accurate?
This makes me way too happy. I love the idea of doing something like this.

CONT. However lets give that explanation a go.
All matter in the universe takes up space. An object in space (say a planet) not only takes up the volume of space it contains...but it also bends that space in three dimensions, a little like a steel ball on a rubber mat.
The heavier (more massive) an object is. the bigger the dent it makes in space. An object close to that 'dent' is attracted to it. We call that property 'gravity' and the dent is called a 'well'
