If you have to ask, you can't afford it.

what came first? The dream or the realization? I think without dreams, nothing is possible. If a person believes that something is not possible, then it will never BE possible for that person. Don't let this be a reason to think it's not. When did a sceptic or a cynic ever think up somthing big? I do also have this strange hunch or suspision that it might be possible to travel so FAST that you could literally travel through matter without disturbing it, kind of like when this person rips the table cloth from under the dishes and wineglasses etc, without displacing them. I have no scientific proof, -argument, or concrete evidence for toying with this thought. It's just a very interesting and fascinating thing to think about. I have wondered about this a long time ago. Besides, it would be really difficult to dodge objects at warp speeds. Don't you agree?

I guess I should say it's impossible ..... Think of the light travelling 93,000,000 miles - in just 8 minutes !!! And that's wicked fast !!! Not even the so-called "UFO & Spaceship" will be able to travel faster than light.....
Do I sound like an alien ???

The light speed is the ultimate speed. We are yet to find / confirm speeds higher than light. As per the law of physics E=mCC, at light speed any object loses its mass to near nil. Neither the space ship nor the traveler would be a reality.

FTL is not possible in this time and dimension. The reasons why not are in a strange way proven by what we do know about light. That is, we understand the properties of light to such a degree that we can build computers, color TV sets, and cell phones, to name a few things. With that understanding of light, thanks to Albert Einstein, also comes an understanding that in order for a particle with mass to attain the speed of light, its mass would have to be infinite. Once you get infinities in your mathematical equations, then it is a sign that something is wrong with the equation. Infinities are not acceptable when calculating thrust vs. mass for your theoretical FTL spaceship.

Of course Not (at present). We do not have the technology to travel that fast. (186,000 miles per second) By the way, the fastest spaceship at present travels only 11.3 miles per second.

cam,
I'm not an engineer, but I would say that we (humans) do not yet possess the technology to make this happen.
In the vacuum of space, it would seem to me that barring the gravitational effects of other planets/stars, a craft would keep accelerating as long as it's propulsion system has the fuel to keep it going faster. Since there is no gravity pulling on the hull of the craft, there should be no stress on it to pull it apart.
The problems, it would seem to me, is 1) There's a lot of junk floating around out there, and the craft would need to withstand direct strikes to the hull at higher speeds as it appraoches light speed...at that velocity, something as light as a gram would go right through anything we have...the results would be catastrophic. 2) How would one navigate such a craft?
I'm sure there's a lot more I'm not getting...

Building a space ship that travels few times faster than light is extremely difficult. Lot's of problems will Drag you down. However, if you build something that travels several hundred times faster than light, things are lot easier.

Yes
Slow the light down by finding a medium with a really high refractive index.
Use perforated silicon as a photonic crystal waveguide.

We already have. they only are not aimed outside the picture voltaic equipment. Voyager a million does no longer have the properly desirable %, besides the undeniable fact that it nonetheless has the properly desirable gravitational potential for its mass.

It has recently been realised that as light has mass, its speed can be altered. That being so, I guess FTL speeds can be theoretically achieved. However, as there's no current way of getting such a ship up to those speeds, you're going to have to run awfully fast to bump start it.
