Greetings,

I was wondering... If you guys had like lets say 1 billion dollars to create a Hyper drive do you think you could do it? Or about exactly how many billions would you need?

I'm talking about getting a group of people together from the public, Universities, free lancers from anywhere in the world to develop a hyper drive.

In addition to that, as well as a cheaper more efficient way to get larger spacecraft into space.

If you guys had a few billions dollars to do it, could you do it in lets say 10 years.

You would also need to find several earth like planets with breathable atmospheres, water, and land to grow food. etc...

No govt would be involved, it would be completely for the public by people who want to further the advancement of mankind.

Let me know your ideas and what you think.

I think we'd need about \$180 billion dollars in about 2 centuries time. The technologies required to go to another system don't exist yet, and thus aren't being mass-produced. However, these technologies certainly are in the process of being developed.

A simple way of doing the calculation is to figure out how much gasoline you'd need: gasoline being a proxy for the energy required to accelerate and decelerate. Then just figure out that the cost of technologically produced goods drops at about 2% per year (in aggregate). Calculate the cost of gasoline, assume it's actually (say) antimatter, and then fudge on the cost of a ship at about 100x the cost of the gasoline.

Viola!

Xeneko - How can you even TRY put a Dollar value on technology that does not yet exist?

That's like a caveman saying to his mate "How many mammoth tusks do you thing it would take to land a cave-girl on the moon?"

El_Machine => i think you underselling yourself => 180Billion?? you are probably 6 zeroes out!

;) Quite a sensational thought I must say...if u keep out the "zeroes' involved

Although the idea is not at all bad I say...u shud rather discuss more on the technology that is involved...to begin with how do u intend to carry out the journey and reach out to habitable planets in one lifetime...we can do the maths what say ??

This is probably slightly off-topic, but it HAS reference to the thread, so bear with me - OK? :

It is impossible to put a value on technology that currently does not exist and has been "Proven" to be impossible. (Imagine one caveman saying to another : "What do you think it will cost to develop a means to drag a mate by her hair to my cave without dragging the skin off of her butt?")

Until someone proves that the Speed Of Light (SOL) CAN be exceeded, the ONLY way we are going to get anywhere is at SOL, or slower.

With regards to the above, I PRESUME then that "hyper-drive" is limited to the speed of light. => we are STILL going to be severely time-limited with regards to interstellar transport. Proxima Centauri, our closest neighbor =4.2 light years.

The ONLY viable interstellar transport I see occurring using current technology is as follows :

1. "Snail Mail" a Teleporter to the next star (at SOL).
2. Build a "Teleporter" at that point.
3. Teleport the materials needed to build another "Snail Mail" + Teleporter..
4. "Snail Mail" another Teleporter to the next star.
5. Continue process until we get to where we REALLY want to go.

This process will not have any direct benefit to US, the current generation, but it WILL enable our descendants to "Leap-Frog" to the "beyond" at a fraction of the time that it is going to take US to get there in the first place.

Teleportation technology already exists (at atomic level) => http://www.time.com/time/health/article/0,...1874760,00.html

Xeneko, rather ask "What is it going to cost to develop EXISTING technology to get beyond moving atomic particles and onto complex materials (or a human body WITH sentience still intact??!!), as opposed to putting a dollar value on technology that is currently "impossible".

OK, NOW the million dollar question :

Is Teleportation instantaneous or is it ALSO governed by SOL??

It's theoretically possible to travel great distance measured in the coordinate frame [laboratory frame] in a very short time recorded in the proper frame [rocket frame]. For instance at 1 g constant acceleration for first half of the journey and 1 g constant deceleration for the 2nd half of the journey the rocket could reach Andromeda in 28 years proper rocket time. Time recorded in the coordinate frame would be 2 billion years. A trip to the center of our galaxy would take 20 years proper rocket time and 30,000 years in the coordinate frame. You can just call the coordinate frame our planet. The star you mentioned is the first on the example list.

If you could resolve all the problems associated with such a journey I would want to go to a place we could settle and populate. Imagine returning from Andromeda 4 billion years in our planets future.

One huge problem would be propulsion and everything associated with it. Look at this paper you can access from waitedavid137 website Modern Relativity. David is a member of this forum.

The teleportation thing is beyond me. It would be interesting to brainstorm what might be required to achieve this goal.

@Boogieman : I guess the bigger problem in teleportation is the rearrangement of the subject being teleported at atomic level. Things wud not be very pretty if we had our nose in place of our mouth once we do possibly reach our destination on being teleported.

On the other hand even if we do counter the problem above, teleportation is only possible by means of what physicists like to term as "worm-holes" i.e. space-time tunnels. If we do get to discover such tunnels in the spce-time continuum then I guess, the journey will definitely be much much faster than SOL theoritically. Practically it might still be lesser than SOL.

I hope this makes sense
