Do it yourself Universe kit

Genetical engineering is often labeled as an activity akin to "Playing God". It is nothing, however to what the physicists get up to. This is an exerpt from an interview with Alan Guth - the creator of the "Inflation" model which describes the behavior of the universe shortly after the Big Bang. Shortly means within 10^-35sec of the Big Bang:

Given the inflationary model, it becomes very tempting to ask whether, in principle, it's possible to create a universe in the laboratory — or a universe in your backyard — by man-made processes.
The first question to look at is what would happen if you had a small patch of inflationary universe in the midst of our universe, never mind how it might have gotten there. Let's pretend that it exists, and ask how it evolves. It turns out that if this patch is big enough, it will grow to become a new universe, but it does this in a very strange way. It doesn't — and this is very important for environmental purposes — displace our universe. Instead, the patch forms a wormhole and slips through it. From our universe, it always appears very small and looks more or less like an ordinary black hole. But on the inside, the new universe is expanding and can become arbitrarily large, creating new space as it grows. It can easily become large enough to encompass a universe like the one we see. In a very short length of time, a small fraction of a second, it completely pinches off from our universe and becomes a totally isolated new universe.

1. This kind of religion is not to my liking.
2. We somehow just recognized existence of the primary universe and cannot comprehend it. Why we should play with other universes especially by creating them without control?
3. There must be first a new "Ministry of New Universes" to control those who would like to make an attempt...
4. I would forbid distribution of recipes like this. It was very irresponsible of you. What if someone created a new universe, sneaked behind you, garbed your head and pushed - just your head - into the other universe? Your neck would stop existing and you could die of hunger. Think about it.

Thanks Zenon, I didn't know what I was doing.

With the power invested in me I forgive you +.
