Quantum Setback For Warp Drives [back to the drawing board]
Slashdot ^ | 4/3/9 | kdawson

Posted on 04/03/2009 8:50:10 AM PDT by Clint Williams

KentuckyFC writes

"Warp drives were generally considered impossible by mainstream scientists until 1994 when the physicist Michael Alcubierre worked out how to build a faster-than-light drive using the principles of general relativity. His thinking was that while relativity prevents faster-than-light travel relative to the fabric of spacetime, it places no restriction on the speed at which regions of spacetime may move relative to each other. So a small bubble of spacetime containing a spacecraft could travel faster than the speed of light, at least in principle. But one unanswered question was what happens to the bubble when quantum mechanics is taken into account. Now, a team of physicists have worked it out, and it's bad news: the bubble becomes unstable at superluminal speeds, making warp drives impossible (probably)."

Except this is exactly what we would be hearing if Tobacco Companies had been big time Democrap donors, instead of Republican

“God is and always will be unknowable to humans.”

I believe that when we die, our consciousness if filled with God’s knowledge (all answers in the universe to all of our questions) and that there may be people alive on earth that might have been allowed somehow, to “know.” I believe those people are seen as insane by the rest of us in some cases. That belief gives me comfort and serenity in knowing that there are some things I cannot know. It soothes a curious mind and helps me look forward to crossing over.

That’s a side effect of faster than light travel...

I arrived back here before I left

You asked — “So you know that God didn’t create wormholes...”

All I have to know about that is He could create one in an instant, if He so desired to do so.

In terms of what to trust in certain scientists statements and also in conjunction with what God can and *does* do, in this world — give me a scientist who does know that God created the universe and all that exists and was created by Him — in those seven days exactly as God has stated in the Genesis creation record of history (chapter one and following), and also knows that God did bring about the world-wide flood as given to us in Genesis (chapter six and following) — and that’s the scientist that I’ll know has a more accurate grasp on the *reality* of God’s creation to be able to find out if wormholes exist or not.

Give me a scientist who questions whether God exists, much less about the creation record and the history of the world-wide flood — and that’s a scientist that I trust as much as I trust what the staggering drunk says on the street while trying to keep himself upright and yelling at people who chance by... :-)

“Lord Kelvin tried very hard to discredit Marconi”

How many years did the court case by Tesla against Marconi take? It was a long time. But, in the end, Tesla won.

Everyone “crosses over” — it’s just that some “cross over” to eternal damnation in the lake of fire (being forever separated from all that is good and of God), while others cross over into being with God, forevermore, in all His goodness and righteousness and blessed grace for the rest of time...

I would say it’s quite important to know which part one is “crossing over into”... LOL...

I find my conception of and my beliefs about God a lot more dependable than they are...

There, fixed it for you.

Unless you claim omniscience.

With all due respect, it isn’t possible to do physics or science while assuming the existence of a God who can change the laws without notice. A believing scientist must believe in a God who doesn’t change the rules without notice, as science is precisely an attempt to find out what the rules are. Rules that change frequently aren’t rules at all.

While many scientists believe in God and the Bible, I’d be very surprised if you can find more than a few who meet your stringent standards.

I see a lot of crazy people in my line of work.

Taken as a whole and looked at individually, I wouldn’t hang my hat on some higher level of meaning coming from them.

It’s well known that smoking or nicotine patches have genuinely beneficial health effects, especially for Parkinson’s and Alzheimer’s. It’s just that the damage far outweighs the benefit.

How many years did the court case by Tesla against Marconi take? It was a long time. But, in the end, Tesla won.

Marconi didn't invent the radio any more than the Henry Ford invented the automobile automobile, or Bill Gates invented the personal computer. What they all did was build a gigantic industry, that transformed Western Civilization, out of bits and pieces of other people's work, when those other people had failed to do so.

I don't have the scientific background to judge the merits of the 28 year Tesla-Marconi patent lawsuit. But when Tesla won before the US Supreme Court in 1943, Marconi's company was suing the US Government for violating its patent. And Marconi, although dead, had returned to Italy and become a very vocal supporter of Mussolini. By ruling in favor of Tesla, the Supremes destroyed the Marconi lawsuit against the US Government.

“quite important to know which part one is “crossing over into”

Quite right, I know which part I am crossing to, so I have much peace and serenity concerning that!

You said — “With all due respect, it isn’t possible to do physics or science while assuming the existence of a God who can change the laws without notice.”

Well, He can and He does, very simply. It happens all the time. They are called “miracles” because God, Himself violates the very laws and nature of the universe in accomplishing these things. He violates the laws of physics and all that we know in doing many thing.

He has set up a universe that operates upon observed and measured parameters. It’s just that scientists don’t necessarily know all those parameters. And in addition to that, some parameters which were considered constants are found, recently, not to be constants. The speed of light, for example, seems to be “running down” and is not really a constant after all. I believe a few scientists are changing their opinions on that one.

So, yes, we can study the “normal” laws of the universe — but — that in no way means that God cannot and does not violate them all the time, as He wishes and at any instant.

Notice, I didn’t necessarily say that God changes the “rules of the game” for the universe itself — but that God violates those very rules, *Himself* in what *He* does... That’s a different story. And there’s nothing in the laws of physics that would prevent Him (if He so desired) to change those on-going laws of physics, at a moment’s notice.

I believe that those laws of physics did change, at the fall of mankind, in the Garden of Eden and that nature of the entire universe (i.e., “creation”) was changed at that instant, introducing the new laws of physics, of which we have decay and disorder and the eventual “running down” of the universe. That *changing* of the laws of physics was done as a “judgement of God” upon mankind and resulted in the “cursing” of the entirety of “creation” (hence, changing the laws of physics from before that time, compared to after that time...).

And it’s likely that another “change” in the order of the universe occurred at the time of the world-wide flood, because conditions changed dramatically at that time. Although that one could conceivably have been accomplished (i.e. that “judgement of God”) without altering the laws of physics, it’s also possible that they were changed.

However, I believe that many scientists, who do study the world-wide flood dynamics, in terms of science, are looking at it from the standpoint that the laws of physics did not change from before to after the flood.

I also believe that part of the curse put upon creation will be lifted (partially) at the coming of Jesus Christ, setting up His worldwide kingdom on this earth — thereby changing (again, partially) the operation of the physical laws of the universe that God has put into play up to our present day. This seems to be indicated by the wording of what I read of the Millennial Kingdom of God on this earth.

And then, *after that* — the laws of physics of the entire universe will be changed — once again (by God’s hands) as he “makes all things new” again, restoring all things back to the way they were at the time of creation, in perfection and without death and decay in the universe.

So, it’s very apparent to me, that God is *constantly changing* the laws of physics, as He has gone along in mankind’s history...

No, I don’t claim it, but God’s Word, itself does claim it for Him and for what His Word says to us. And thus, we do have that knowledge given to us from what He has said in His omniscience... :-)

That’s enough “omniscience” for me...

OK - just what is that silver thing standing upright to the right of Scotty?!?

It looks like something the Chief Engineer picked up during his last visit to Starfleet HQ in San Francisco....
