Exactly.

A white dwarf, red dwarf, brown dwarf or any star for that matter when we look up at the night sky (excluding non-blinking celestial objects) have the potential to create a black hole when they go nova. In time, a star will burn out, explode, get created again, burn out, blow up . . . it's a vicious cycle and it takes billions of years. However, during a super nova exlosion, and we're talking a damn big star, maybe 3 times as big as our own, it might have the off chance of producing a black hole where as when the star collapses, the gravitational force is so strong that it overwhelms the force of outward motion and collapses upon itself. Now there is nothing to hold back collapse and it collapses into a point of infinite density. When the mass inside the given region of space increases, its gravity becomes stronger is what I am trying to say. When the star explodes, it will be pulled back to its focal point/center of explosion and collapse on itself. It makes a hole in space. The center, being the singularity, contains the remnants of the previous stars mass, supposedly. Time is also in a jumble. That's the low down.

Anywho, I wish I could be around for when we start space traveling, that is if that stupid asteroid doesn't hit us or if we blow ourselves up. I kind of want to be there when we have more space stations and possibly ships to carry people from planet to planet.

Just two quick side notes though:

1) Black holes do have "orbits" so they are floating around.

2) If we were to space travel and go to say Jupiter, our bodies would age at a slower rate than that of Earth's time. If we were to take that trip to Jupiter and go back to Earth, time would have changed severly since you had left. I am not exact as to the time stat, but I believe a few years would pass from the short time it took you to go to Jupiter, and the time it took you to get back.

Time is different everywhere...

That would be very scary when a big chuck of space rock hits earth. Your statement kinda reminds me of a sci-fi anime. It's something like Mobile Suit Gundam: Char's Counter Attack.

Travelling to space would be possible in several decades when launching a space transport becomes cheaper & more convenient.

Jupiter isn't far enough. At the most, the time difference would be a matter of minutes, since when you finally get fast enough for there to be a significant time difference after returning from your journey, the total time spent getting there and back will be only a few hours.

The key to triggering the relativistic effect of time dilation is acceleration, not velocity. If you're up to trillions upon trillions of G-forces, you could outlive the entire solar system on a voyage to Jupiter.

Keep in mind that according to Einstein, time is relative to the perspective of the viewer. I think it's safe to say that unless some little green alien lands here, or somebody comes back in time with information about FTL travel, none of us will live to see the day a human travels faster than light.

We will see many, many, other advances though. Which I look forward to.

Except you'd still have passed Jupiter.

I can imagine Deep Space Travel, but we would really need to achieve Higher speeds, and the Crew wouold have to get along ( reproductive-wise ) or ele were in the dust

If you've got the power to do all that acceleration, then you could accelerate in the reverse direction for only double the cost. Not a problem when we're talking about forces so grand!

Well, it'd actually be four times the cost, plus a bit more for the engineering aspects.  You've got to make one burn to get going, one burn to reduce your velocity to zero at wherever you're going, one burn to go back the other way and one burn to park, and you've got to carry enough fuel for this.

Heh...nobody said anything about a return trip. Indeed, at the accelerations we're talking about, there wouldn't be an Earth to return to!

We would have bast possibly billions of years into the "Future" You might say, but if we could limit such a thing, we could use it to regulate in years, in the future you would want to go to, and be in the future, but with an problem, on the travel back...

Have you consider a Dark Matter Generator to power the warp drive?  Dark Matter has a near infinite energy source.

How do you define "near" infinite?

Almost inexhaustable power source. Since 90% of space is dark matter(In scientific terms, dark matter is a matter or energy that doesn't emit light.), you could say that you'll never run out of power source.

Even if dark matter can be used as a power source, you have to get some first.  Right now we have no idea how to do that, or even if it can be done.
