This worm hole I'm constructing needs a lot of power to keep it open. I gather it needs about as much power as there is in the visible universe.

How do I set about harnessing this energy source? Obviously I need to concentrate it in a fairly small area, maybe a few of square metres, or at least big enough for me to climb through it.

What technical hurdles do I need to overcome?

wiil not the piece attach to the maget only after eight years i.e. 4 light years for the energy to reach the iron and 4 light years to come back.

let us consider an object which consists of the 7 colors. now all the seven colors having different refractive indexes of their own will meet at different points. but to see the all the colors the intersection must be at the retina. so only one of the color must be seen, isn't it?

At the moment in Scotland, the moon is incredibly bright at night, much more so than it is usually, even during a usual full moon.  Why is this?

I assume that the brightness of the moon is based on the angle of the earth, moon and sun, but if so then what is the critical angles to get the brightest moon possible?  When will this next occur?

Considering we have mapped the relative speeds and positions of thousands of galaxies, and so know how fast they are moving and where to, has anyone tried and run the whole process in reverse to see where they all originated from?

This should be ground zero for the big bang (if all matter originated in a point) and would be some evidence for the theory that all matter originated from a single point.

if this point exists, what would be there? Would there be galaxies and stars closer to the point or would that area of the universe be empty of all matter (it having all been propelled out by the big bang)?

There are many predictions made by scientists about the fate of the universe. One of them is the "Big Rip". So the question is, what will happen after the "Big Rip"?

So here's what I think will happen, feel free to correct me if I'm wrong.

1. The universe is expanding and it has been known and proven. If it continues at this rate, every matter inside the universe will be ripped apart.

2. But when the universe reaches it's "elastic limit" and can go no further, it will collapse with great force back into the centre of the universe.

3. When this happens, everything in the universe will shrink back into the size of an electron(or maybe even smaller) with an "infinite" amount of density. This can soon turn into another "Big Bang".

4. And therefore the steps repeat itself when there is another Big Bang.

Example: Imagine a coil of spring. If you compress it very tightly, it will repel back at you with great force. If it is pulled very strongly, it will pull itself back to it's normal shape with great force.

I believe that the universe is like a spring, but the only thing is that it doesn't have any definite shape.

Consider a tiny cell. And in this cell there are millions of atoms(or more). Now consider a galaxy where it too, includes millions of solar systems(which looks like atoms).

So the question is, does anybody else think that our solar system is nothing more than a tiny atom inside a cell(known as the Milky Way) of something very, very huge?
