How insignificant most of our lives are.

No other life form out there ? wake up people.

**The galaxy, titled NGC 4911, lies more than 320 million light-years away in the “Coma Cluster” of about 1,000 galaxies and islands of stars similar to the Milky Way. Nasa said the stunning long-exposure picture, titled “Island Universe”, shows the “majestic face-on spiral galaxy” in the northern constellation Coma Berenices amid a sea of stars.**

Using Hubble’s brand new Wide Field Planetary Camera 2 and the Advanced Camera for Surveys, it required 28 hours of exposure time. The long wispy formations, seen along the “arms” of the main galaxy, are a result of the nearby galaxy passing “perilously close to each other”.

“The high resolution of Hubble’s cameras, paired with considerably long exposures, made it possible to observe these faint details”, a Nasa spokesman said.

And of course, no risk to the stability of our world.”

That’s reassuring… until Mothman comes through the dimensional doorway with a legion of Mothmen to take over Earth in the name of King Hybreed Manthuzlar IIV. Only time will tell, I suppose.

what do you guys reckon could come through?]]>

Most of us are stuck inside the three dimensions of space -- height, width, and length -- and one of time. Our everyday brains do not bother with more than four dimensions. Yet mathematicians work in thousands, even millions, of dimensions with ease. How can this be?

A dimension is a measurement of something that changes. The something can be an object such as a rubber band, which expands and contracts through the dimension of length. It can be an extension ladder that grows or shrinks through the dimension of height. It can be an ice cream sandwich that loses the dimension of width as it is eaten.

How do we describe a multidimensional object? With coordinates.

For example: When a person walks down the sidewalk, he moves through three dimensions of space in a period of time (the fourth dimension). A mathematician would say that at any given moment the person has three coordinates of space: numbers corresponding to distance in terms of length, height, and width. And, of course, a time dimension coordinate is described as -- what time it is!

Nor are dimensions limited to space and time. Heating an object pushes it through a dimension of temperature. Weight is a dimension of mass.

When a mathematician wishes to move an object through more than the ordinary four dimensions, she simply adds coordinates for the extra dimensions. The four-dimension, space-time coordinates for the person on the sidewalk might be: a length of 20 feet (x = 20) from the beginning of the sidewalk; a width of 2 feet (y = 2) from the edge of the sidewalk; 6 feet (z = 6) above the walk's surface; at precisely 10:30 in the morning (t = 10:30). Add a coordinate for body temperature -- 98.6 degrees Fahrenheit, if the person's healthy (f = 98.6) -- and, voila, that person is described in five dimensions with coordinates x, y, z, t, and f. You can add on as many variable coordinates as you can dream up.

What about extra dimensions of space?

According to currently accepted theory, when the universe was born in a massive explosion -- the Big Bang -- all of space and time were created. Three dimensions of space and the dimension of time were very large -- that is, as large as the entire universe. But the seven extra dimensions described by M-theory did not explosively unfold. According to the theory, they remained tiny and curled up. And of course, only extremely tiny objects can be measured by the tiny dimensions. So a little object -- such as a string -- has three coordinates of large space; one coordinate of large time; and seven coordinates of tiny space. Each string can be described with a total of 11 coordinates.

Think of the seven infinitesimal spatial dimensions not so much as places as measurements useful for determining where a small object exists.

Do not try to visualize the space occupied by an 11-dimensional object in your brain, because if you try, you may well go crazy; except through higher mathematics, the human brain cannot generally conceptualize more than the four familiar dimensions our senses convey to us.

You insist on trying anyway? OK: Imagine that you are a Line-person from the land of Line. Naturally, you live on a line -- you are a one-dimensional person living comfortably in a one-dimensional space. What happens if a two-dimensional circle comes to visit? How do you see it? You see it from the side, as a line, of course. Being a one-dimensional person, you cannot visualize something in two dimensions -- such as a circle. If you want to "see" the circle, you have to evolve into a two-dimensional person.

Say you are happily living in two dimensions and a sphere comes to visit. What do you see? A circle, of course, because you cannot see depth. Since a sphere is three-dimensional, you cannot perceive all of it in two dimensions. You have to move up to the third dimension in order to see all of the sphere.

Physicists have discovered that by stepping into higher dimensions, they increase their perspective in relation to objects. A one-dimensional person stepping into two dimensions sees the whole circle, which, in three dimensions may turn out to be a sphere.

The same type of thinking has been followed to yield the 11-dimensional perspectives of string theory.

When physicists view the tiny loops of string in only four dimensions, they see only certain modes of the vibrating string, reflected as electrons, protons, photons, and other small, but measurable, entities of our physical world. When described mathematically in 11 dimensions, more of the string's existence, and more of the richness of the universe, is revealed.

I wonder if he went back and saved his dad, would he have then changed his life, so he did'nt build the time machine to then go back What would REALLY happen.

Is this even remotely possible? I say NO!]]>

(Season 1, Episode 4) Stephen Hawking's theory of black holes and Richard Gott's theory of cosmic strings give hope to those seeking a route to time travel.

A 3700 year old wall measuring 26 feet high has been uncovered in the city of David in Jerusalem. It also measures about 79 feet deep but israel antiquities authorities believe there will be more uncovered. Each boulder lining the wall is estimated to be 4 to 5 tons. This is one of those miraculous feats our ancestors accomplished with brute strength and determination. They believe it is part of a protected area or what they call fortified in an effort to keep out thiefs. I just found this very interesting and wanted to share the info.
