"Two Timer" Physics

[dgridley]

For a long time, Itzhak Bars has been studying time. More than a decade ago, the USC College physicist began pondering the role time plays in the basic laws of physics — the equations describing matter, gravity and the other forces of nature.

Those laws are exquisitely accurate. Einstein mastered gravity with his theory of general relativity, and the equations of quantum theory capture every nuance of matter and other forces, from the attractive power of magnets to the subatomic glue that holds an atom’s nucleus together.

But the laws can’t be complete. Einstein’s theory of gravity and quantum theory don’t fit together. Some piece is missing in the picture puzzle of physical reality.

Bars thinks one of the missing pieces is a hidden dimension of time.

Bizarre is not a powerful enough word to describe this idea, but it is a powerful idea nevertheless. With two times, Bars believes, many of the mysteries of today’s laws of physics may disappear.

Of course, it’s not as simple as that. An extra dimension of time is not enough. You also need an additional dimension of space.

It sounds like a new episode of “The Twilight Zone,” but it’s a familiar idea to most physicists. In fact, extra dimensions of space have become a popular way of making gravity and quantum theory more compatible.

Interesting stuff!

Unfortunately, theoretical physics is full of quacks.
The most famous quack being Stephen Hawking.
Real physics requires a proof that can be duplicated by anyone in a lab.

That article just annoys me.

The theory of that many dimensions is nothing new, and Mr. Itzhak should know this. The annual string theory conventions are held at USC. String theory calls for 11 dimensions, so I don't know what this guy is trying to do by announcing this around 100 years after they were thought of.

He's proposing 11 spatial dimensions, plus 2 for time.. for a total of 13.. made sense to me when I read it?

I didn't read to the very end because that article isn't that interesting, but now I did.

Adopting the more symmetric two-time approach may help. Describing the 11 dimensions of M theory in the language of two-time physics would require adding one time dimension plus one space dimension, giving nature 11 space and two time dimensions. “The two-time version of M theory would have a total of 13 dimensions,” Bars said.

If he even knows M theory, he would realize that the reason it works is because it uses 11 dimensions. That was the big change from string theory to M theory that made it work.

“My hope,” he says, “is that this path that I am following will actually bring me to the right place.”

Have fun with that..

Even if he is right, what's it gonig to change? In the end won't the world be the same anyhow?

Once we can understand the way things work, it can lead to more exciting developments. The world may be the "same" but our understanding of it will change. A car may look the same but it changes once you learn to drive it.
