This is a video of two deep space experiments using the Hubble space telescope. First, Hubble was pointed to a "dark" spot in space and left to collect data for 10 days to see if anything was there. The second is to use this data and the Red Shift to create a 3D image. The result is presented here. To me, pretty amazing stuff.

The theory claims “space-time” itself is being created by the expansion. There is no space or time outside the expansion.
We have a couple of billion years before the Sun becomes a red giant and swallows us. That leaves some time for technology to solve the problems you mention. Watch Through the Wormhole, etc for people looking into these issues now.
Its not likely. But it is possible.
No, it's not possible. I dropped the Commie rag paper almost ten years ago.
As to that other thing, do you think .300 winmag would be enough, and will peterodactyl taste like chicken too?
Wow, I am so impressed. I SOOOO glad somebody is looking into this! /sarc
I wouldn't say at this early point that it's impossible. But moving ahead in time is happening all around us all the time. Whenever an object is being accelerated (having a force applied to it), it is, with respect to objects outside its frame of reference, it is moving ahead in time. And since acceleration is a vector quantity (has both magnitude AND direction), a change in direction alone would/could also do the trick. As long as the object departs from its inertia state of motion, it is moving ahead in time with respect to objects in other reference frames. Inertial motion is straight line, constant speed motion. ie, what happens to drifting objects in space away from gravity fields. An object will continue its inertial state of motion unless acted upon by an outside force. A force is needed to either change its rate of speed AND/OR its direction.
Speaking of physical properties, I can't for the life of me understand how the big bang managed to make all the suns and planets into round, ball shaped objects like marbles, on a universal scale.
Yes, there are a few major problems with the big bang theory. Not to say that the expansion isn't really happening, but that there's some serious problems in terms of it being a complete theory. Inflation theory was specifically created/concocted to solve these various problems with the standard big bang model.
The following is from a website called hyperphysics...
1. The Horizon Problem
2. The Flatness Problem
3. The Galaxy Formation Problem
4. The Antimatter Problem
Here is an excellent source which explains in layman terms what these problems are:

And here are some things I(ETL) found some time ago on inflation theory...
Alan Guth [inventor of Inflation theory]: "Those 'little creatures'[cosmic microwave background photons], however, would have to communicate at roughly 100 times the speed of light if they are to achieve their goal of creating a uniform temperature across the visible Universe by 300,000 years after the Big Bang." http://nedwww.ipac.caltech.edu/level5/Guth/Guth2.html
As Albrecht, now at the University of California at Davis, puts it, inflation is not yet a theory: "It is more of a nice idea at this point."...
"The model in Guth's original paper, published in Physical Review D in 1980, admittedly did not work. Michael Turner of the University of Chicago, who took part in Bardeen's calculation of the density perturbations, says Guth had been brave. "One of the striking things about [Guth's] paper," Turner says, "was that he said: 'Look, guys, the model I am putting forward does not work. I can prove it doesn't work. But I think the basic idea is really important.' "
In fact, Guth's "old" inflation ended too soon, and too messily. A "graceful exit" was needed to make the universe look remotely similar to ours. In 1982 Paul Steinhardt, another co-author of Bardeen's calculation, solved the graceful exit problem together with Andreas Albrecht; Linde also found a solution independently. Their "new" inflation worked by adjusting the shape of the potential function, a sort of mathematical roller-coaster that defines the properties of the inflation.
Most of the mechanisms proposed ever since rely on carefully adjusting the shape of the hypothetical potential function. None, it seems, has been too convincing. "All these models seem so awkward, and so finely tuned," says Mark Wise, a cosmologist at the California Institute of Technology.
Physicists would like a theory that avoids such gimmicks, one that shows how things ought to be from first principlesor at least with the smallest possible number of assumptions. "Fine tuning" is the opposite.
It was two fine-tuning problems, two such implausible balancing acts, that inflation was supposed to have solved. "You're trying to explain away certain features of the universe that seem fine-tunedlike its homogeneity, or its flatness," says Steinhardt, now at Princeton University, "but you do it by a mechanism that itself requires fine tuning. And that concern, which was there from the beginning, remains now." As Albrecht, now at the University of California at Davis, puts it, inflation is not yet a theory: "It is more of a nice idea at this point." "

"The Hubble Ultra Deep Field, or HUDF, is an image of a small region of space in the constellation Fornax, composited from Hubble Space Telescope data accumulated over a period from September 24, 2003 through January 16, 2004. It is the deepest image of the universe ever taken in visible light, looking back approximately 13 billion years, and it will be used to search for galaxies that existed between 400 and 800 million years after the Big Bang.The HUDF image was taken in a section of the sky with a low density of bright stars in the near-field, allowing much better viewing of dimmer, more distant objects. The image contains an estimated 10,000 galaxies.
Located southwest of Orion in the Southern-Hemisphere constellation Fornax, the image covers 11.0 square arcminutes. This is just one-tenth the diameter of the full moon as viewed from Earth, smaller than a 1 mm by 1 mm square of paper held 1 meter away, and equal to roughly one thirteen-millionth of the total area of the sky. The image is oriented such that the upper left corner points toward north (-46.4°) on the celestial sphere."

Think of fluids, plasma as like water falling from the sky. The water drops are spherical until they hit your windshield. This is how shot was made during the civil war. Hot lead was dropped from a tower, it became round and cooled enough to stayed that way on impact.
The warp drive: hyper-fast travel within general relativity
There is a fee to download the extract.
Gravity did that millions of years after the big bang. The stars and planets were formed from loose material clumped together by gravity. Since gravity works the same in every direction, objects naturally become spherical.
Once you understand that time is going backwards rather than forward everything makes sense.
Just try answering- the question
Your whole premise it that nothing in physics (that we know) allows for interstellar travel.
So...for the last time...
Do you think we know everything there is to know about physics?
It’s OK- when you have lost the argument it is good to concede a point- try it.
Learning happens only when you listen - not when you speak. When you speak you only let people know what (little) you know.
If you think the question is irrelevant than you need to go back to school and learn HOW to think, instead of WHAT to think.
Just think of other dimensions as Bubbles as seen on the Lawrence Welk Show. Someday we will figure out how to move from one bubble to another.
Oh I see... so now you make fun of research? How do you think we discover things, Einstein?
How old are you?
If someone thinks Jeff Davis can’t be wrong, would you expect them to believe Einstein can be improved upon? ;)
If you believe that one day their will be some physics that allows time travel and we will be able to translate that into some form of useful technology, I would argue these are religious beliefs not scientific.
geez what college did you go to?
Your arguments are back-asswards
We could discover something new tomorrow.
We could say there is already ample ‘evidence’ that contradicts the fermi paradox (pyramids? ancient writings from numerous diverse peoples that talk of visitors from the stars...
You seem like you have gotten a little knowlege and thing it makes you brilliant. I read the Fermi Paradox before you were born, probably.
It never ceases to amaze me that someone like Central Va thinks that he is educated, just because he has learned to copy and paste.
Reminds me of the bar scene in Good Will Hunting.
THe human race cannot even make good on current physics, quantum theory. There is no unifying theory either. Maybe there never will be? You can keep wishing for the stars, I am done with it. Have fun. Plasma physics, stars it's all the same. Boring to me. There isn't anyplace worth visiting anyway.
This doesn't mean I don't think a mission to the planets in our solar system isn't viable.
