You Can't Travel Back in Time, Scientists Say [yaS stsitneisC ,emiT ni kcaB levarT t'naC uoY]

"Wormholes are the future, wormholes are the past," said Michio Kaku, author of "Hyperspace" and "Parallel Worlds" and a physicist at the City University of New York... To punch a hole into the fabric of space-time, Kaku explained, would require the energy of a star or negative energy, an exotic entity with an energy of less than nothing... Another popular theory for potential time travelers involves something called cosmic strings.. Cosmic strings are either infinite or they're in loops, with no ends, said J. Richard Gott, author of "Time Travel in Einstein's Universe" and an astrophysicist at Princeton University. "So they are either like spaghetti or SpaghettiO's."

Godel used Einstein's own theories and equations to show that time does not exist. Exasperated, Einstein sdmitted he could find no fault with Godel's calculations.

"You can't travel back in time..."

Scientists are such idiots. Have they forgotten about the flux capaciter?

Here's a thought...

- Einstein tethered us to linear time because he linked relativity to the speed of light (velocity). You cannot have a negative velocity so, according to Einstein, time is ever moving forward in a linear way.

- "Time", as we know it, is a contrivance of Man (stuff happens and we devised a means of measuring durations, like 'quarters' in a football game). Time, as we measure it, is merely increments of eternity.  

Time travel is a realistic possibility, however, time travel does not include a 'device' (eg. time machine). It (time travel) is a function of the soul (or spirit) which exists both within and outside of time simultaneously.

- Our 'ego/physicalbody' is a time-based entity which, when transcended, liberates us to navigate to any imaginable space-time context. In brief, time travel is an inherent characteristic (ability) of our 'true self'.

- The 'reality of time' is that it is always "now" and the human condition seems to be that our minds and physical bodies are not (usually) in sync.  Our bodies are always 'present in the now' and our minds are always (usually) in either the past or future. When the mind and body merge into the instant then magic happens and eternity reveals herself.

I loved that show. I remember the time when they went back to the Alamo. I often dream about going back but taking some modern weapons with me. Maybe just some repeating rifles and some six-shooters.

If time travel into the past is possible... then it's reasonable to think that at some time before the next millennium, someone will have found a way to do it and perfected it... and if they're able to do it, people would have come back in time and would be noticed. This hasn't happened...

So, this leads to three possibilities:

1. Time travel is impossible.
2. Time travel is possible, but the people coming back in time have been very, very covert about it.
3. Something cataclysmic happens that stops scientific progress before time travel is invented.

Goedel said that, but Einstein was not exasperated. It might be interesting to note that to a photon neither time nor distance exists.

Here are three time travel methods, although they only go in the direction we're used to... ;')

I put instant coffee in a microwave oven and almost went back in time.

LOL... somehow, I expected to see this phrase in the article:

While his team still needs funding for the project, Mallett calculates that the possibility of time travel using this method could be verified within a decade.

"So really... all I need is some Government agency to give me $500,000 a year for the next 10 years".

J. Richard Gott is a good one. If there is an expert on time travel, he is it. Michio Kaku is a lost cause.

I view Time as more of a magazine...

Now ask me about Life...
