Thanks to the introduction of our Space Force, I expect we will soon see more and more craziness hit the public sector, but for now the US Government finally confirmed the existence of their long-running open secret program called AATIP (Advanced Aerospace Threat Identification Program).
Err... no.
NASA is already on top of that stuff and the Air Force easily handles the rest. We won't need an actual Space Force for another fifty years.
That having been said...
The future of humanity is in the stars. We will either stay on Earth and eventually perish or we will spread beyond our current habitat.
A workable Warp Drive would be the end goal of space exploration. Everything after that is just the natural instinct of humankind to go anywhere they can.
And hump anything they find, but that is less majestic.

I must not have made my point clear. Apologies. What I meant to say is that thanks to the introduction of our Space Force we will now see technology that has been developed by the US Naval Space Command leak into the public sector. Because the whole thing has been consolidated and pushed forward to the public's psyche. Before these projects were black. As in, the projects that are outlined in the recently publicized project AATIP's responsibilities. Traversable wormholes, star gates, negative energy, so on and so forth.
I do agree that we will eventually colonize other worlds though.
Hell, we already have.

workable Warp Drive
I wonder how relativity would play out in the case of traveling to the stars with a warp drive. If we traveled at close the speed of light or faster we would arrive back on earth in a future that may not even have humans any longer but I suppose it may not happen if we are warping the spacetime around the ship rather than achieving ftl speed. Just a thought.

Not with the laws of physics in this Universe, maybe in another. In our Universe, the Second Law of Thermodynamics reigns supreme. The arrow of time is in only one direction. This means that order degrades to disorder universally. Low entropy seeks to become high entropy.
Low entropy conditions can arise from the rush towards high entropy, such as the galaxy we live in, but the ultimate fate of our Universe is one of a uniform equilibrium of the highest entropy.

No, they don't. You're probably thinking of the double slit experiment wherein a photon will instantly collapse to a particle when observed, even after having passed through the double slits as a wave. The perception that it traveled back in time is an illusion. It has merely responded to detection by collasping to a particle at the point of its emission.

wrong bc if anything traveled backwards in time it would be floating 100's of thousands of miles away in outer space.
When I watch re-runs of The Andy Griffith Show they come in clear and crisp.

But cant that law be broken by Maxwell's Demon? Entropy is reduced in that case
Of course the device has never been built, its just been proposed

It's a fun thought experiment but there can't be a practical application of it. Another example of impracticality is the prediction by mathematics that travel to the past is possible. Forward travel in time has been observed but there's no experiment in which travel to the past can be observed.
The First Law of Thermodynamics states that heat is a form of energy and thermodynamic processes are therefore subject to the principle of conservation of energy. This means that heat energy cannot be created or destroyed.
The laws of thermodynamics are based on a closed system. This means that no new energy can be introduced. The Universe is such a closed system. Therefore, all low entropy will move to high entropy, or a universal equilibrium.
We are evidence that, in this process, there are pockets of very low entropy that are sustained by the introduction of energy, from our sun in our case. Energy sources such as stars are caused by gravity, the archenemy of entropy.
Of course, gravity has its own archenemy, dark energy. Right now, dark energy is winning and the Universe is rushing towards its ultimate entropy faster than it was 6 billion years ago when gravity was a stronger opponent for dark energy.

Lots of ideas can be simulated. However, many can't be observed.
The idea of wormholes is fading in the physics community. While there are good theories for them, they're one of the things that can't be supported by anything but theories. Kind of like traveling at the speed of light. Theoretically it's possible but the amount of energy to do that is far greater than can be generated by any known means.

I think it could be done. The issue becomes finding the speed of the molecules in the chambers, and being able to base the door's opening and closing off of the data from the speed readings. It would be difficult but I wouldn't be inclined to say it will always be impossible to do. But then you have to take into account the amount of energy required to run such a device and that could counter any reduced entropy in the box

Entropy is a weird concept to think about. The thought that many of the stars we see in the night sky are already long gone is scary enough, much worse to consider the idea that all stars including our own sun will eventually go out.

Well, the point of the thread is that the Government has been spending a lot of money on this work. Now, admittedly I added the time travel bit in here myself, but if they have developed the means to create wormholes then it isn't a far stretch from there into the time travel realm.
What sort of energy source can collapse space-time in on itself? No idea. But they're clearly tinkering with some heavy duty stuff and I know JPL has been working on warp propulsion. They've said as much.
Exciting times.

Glad you thought that through.

To completely go out, however, will take trillions of years. No star is completely gone yet. Rather they evolve (devolve?) into such things as blackholes, neutron stars, white dwarfs and the like.

JFK jr. is deader than rfk. JFK senior is still alive though, heard he's a dj in northern Michigan

I'll give it some thought. 
Did you know that the California state legislature passed a law to prevent people from suing PG&E over all these wildfires?

Thought I heard something about that but didn’t give it much thought because in general DGAF about the fires or California. Is that to protect a public utility from going under or something? Are you saying there’s an ulterior motive?
Posted on 1/24/19 at 7:59 pm to KSGamecock
Well, PG&E is responsible for the fires. Whether that's due to poor practices or something else would be for someone else to decide. And unfortunately, the courts won't ever get a chance to decide.
Anyways, I'll probably be staying away from those subjects to be honest. They're too contentious.

The government spends lots of money on things that will never produce results. It's called waste. There was once a "department division" that had the sole purpose of regulating the consistency of cranberry sauce. It had one employee who, for a salary of $72,000 per year would take a knife and slice gelled cranberry sauce and then file a report on its quality.

It isn't spacetime that collapses. It's mass through the effect of gravity. Mass is compressed. Gravity bends or warps spacetime, causing any mass that approaches this "gravity well" to join the existing mass and to be compressed as well. Of course, the gravitational effect of the new mass is added to that already existing for a net stronger gravity of the object.

This kind of fancy smancy high faultin science mumbo jumbo is way more convuloted and handwringingly hypothetical than anything you’ll find in any religion. Physics is for fast talking shmucks.
