OBAMA'S SPEECH TO A CROWD THE DAY AFTER SANDY SWEPT THRU.
Americans have suffered a real tragedy, and it affects ALL AMERICANS, and we will not finish helping here until everyone has been helped, we will leave no American behind.....
unless you are in Benghazi.
ITS a win/win for republicans, Obama is going down on Nov 7th, and if by some miracle she doesnt, Benghazi will take him down and be his legacy. And for a triple triple, Hillary is going to be roasted on this also.
There is no Allah.
Mohammed, like Joseph Smith, invented a religion so they could legitimize their sexual appetites.
Yes, time travel is theoretically possible. But it would be very difficult because the energy associated with an object's rest mass has to be overcome.
A typical setup for time travel involves two fast moving supermassive black holes flying past eachother. If you pilot your spaceship towards the gap where they have already just converged in the immediate past, the gravity from the past could fling your spaceship into the past. The blackholes must be extremely massive, and the gap distance sufficient to create a uniform gravitational field, otherwise your spaceship would simply be torn to pieces.
In reality, simply two black holes would probably not be enough. One would have to align several stages of black hole pairs in a sequence for this to practically work.
Tremendous energies need to be involved for time travel, and these energies must be carefully controlled if you do not want to be merely blown apart into subatomic particles. Suffice to say humans do not currently have the capacity for sending any significant quantity of matter back in time. It may be possible to send signals a fraction of a second back in time using current technology. While scientists do not know with certaintly, likely there would not be any "paradox" phenomena observable. Coherence and quantum entanglement prevent this. On much more macroscopic scales, this type of paradox-preventing phenomena would have much more bizarre manifestations. For example, someone who tries to go back in time to kill themselves before they were born would find that it was impossible because strange (extremely unlikely) coincidences would thwart their efforts.
Also, going back further into time might be exponentially more difficult, because of interraction between "the butterfly effect" and statistical resistance to paradox-formation. Going back in time 1000 years and touching even a single blade of grass would hypothetically substancially alter the outcome of the future, so the time-loop of existence would need to compensate to prevent the future from being altered (which would create a paradox forbidden by the laws of nature). Statistically, the more the time-loop would need to "compensate", the more difficult it may be to go back in time. Notice that by "compensate", this is not an actual event in time, it is merely something which exists as part of time, a simple relationship between events. Trying to understand sequences of events in terms of "cause and effect" becomes meaningless in time travel.
Indeed, it might even be possible that the failure of any scientists to attempt to send a signal back in time could actually be a macroscopic manifestation of this bizzare law of nature, to prevent any paradox from forming, although this is just baseless thought-provoking conjecture on my part.

The energy needed to travel faster than the speed of light is not there... because the faster something moves the more force it takes to push it.
When you get near the speed of the light the mass of any object (that has mass) is so large you cannot muster enough force to push it faster. It "weighs" too much.
Place a baseball on your bare foot....then drop a baseball on your bare foot from shoulder height if you disagree.
The truth is neither right or left...it is the truth.
This could be why neutrinos have been able to exceed the speed of light, since they have such little interaction.
Since the vacuum energy has an extremely high energy density, the energy of a particle would have to be extremely high for it to exceed light speed, which has never been observed.
The other strategy would be to "rarify" the vacuum. Essentially two reflective parrellel plates (Casmir effect) on a huge scale (many lightyears wide), could allow a particle to travel slightly faster than the speed of light. But from another persective, since the space between the plates would be warped, the speed of light would still be conserved within the framework of relativity.

I'd like to mention particle accelerators.
We've observed time dilation in those.
But using atomic clocks we've also observed time dilation on planes.
As I said, we're always time travelling.

I still follow Al.
It may be possible to warp space but that would not be traveling FTL...the object we were travelling to would be closer.
If you could warp the space between here and Mars to make the journey in an hour. The hour journey would be in real time.
You would get there an hour after you left Earth. Mars time and Earth time.

My guess is that going back in time would be even more difficult than people imagine. The normal fabric of space would likely try to resist anything going back in time, just like it resists anything trying to exceed the speed of light. To send something back in time, likely space would have to be extremely warped also. If you want to think of it this way: a temporary man-made "worm hole" into the past.
We know space-time is affected by gravitational fields.
I believe the past and future exist in the same way that the present exists. Think of it this way: you only believe the present exists because it is the present you that is thinking. The past you, 1 hour ago, thinks the exact same thing.
Time only appears to flow from the human perspective. It has already been demonstated through quantum entaglement, and phenomena such as the double slit experiment, that the "cause and effect" relationship is an illusion. There is a connection, a correlation between the past and future, certainly, but there are instances we see where the future appears to affect the past. This phenomena is typically not obvious in ordinary human existence, though it is necessary to explain why we can even see our reflection in a mirror. If it was not for the fact that photons are forbiden to annhilate eachother in the future, there would be no coherence, and without coherence, all the photons reflecting from a mirrow would bounce off in random directions, because each individual photon is actually transiently absorbed by individual spherical atoms.

It seems to me that there really isn't much difference between the "energetic fabric of space-time" that we all plough through and the classical notion of an ethereal plane overlaid with the physical plane. But the notion of 2 black holes actually sending a sizeable something back in time, compared with the theory of "one timeline", where all time travel changes have already been factored in to what is, was, and will be, reminds me of an explanation for the Big Bang that I heard once: That "stuff" came back from a possible future, destabilizing the singularity. With a universe that seems to have preferences to prevent paradox, preferences to do everything with the least effort, perhaps it prefers to exist?
Behind this mask, there is more than flesh and blood. Behind this mask is an idea. And ideas are bulletproof.
Q: President Obama, how can you target innocent women and children with your drone strikes?
A: Easy, you just don't lead them as much.
