"causing no harm to the fabric of our universe."

Physicists In Japan Plan To Create New Universe In Lab

A radical new project could permit human beings to create a "baby universe" in a laboratory in Japan. While it sounds like a dangerous undertaking, the physicists involved believe that if the project is successful, the space-time around a tiny point within our universe will be distorted in such a way that it will begin to form a new superfluid space, and eventually break off, separate in all respects from our experience of space and time, causing no harm to the fabric of our universe.

"[T]he baby universe has its own space-time and, as this inflates, the pressure from the true vacuum outside its walls continues to constrain it. As these forces compete, the growing baby universe is forced to bubble out from our space-time until its only connection to us is through a narrow space-time tunnel called a wormhole..."

Eventually, the "umbilical" connection between our space-time and the baby universe would be effectively cut, and the baby universe would enter into its own unique process of unending expansion. From our perspective, it would be lost inside a microscopic "black hole", which will not appear to expand into our space-time. Hawking radiation will be emitted and the tiny black hole will "evaporate", sealing the separation between the two universes.

    That sounds like an excuse to blow up the universe.

    I am somehow not reassured in the least by the hollow sounding promise to "cause no harm".
    On the other hand,it would make for a great "I Love Lucy" episode.

    (scene- destruction of space-time continuum)
    Desi: Lucy, you have some splainin to do...
    Lucy: Waaaah!

    Universes are recursive!

  4. Yeah, I did that back in 1995. There was this completely separate universe I created in my living room. The experiment was fully successful, so much so that this parallel universe is now completely undetectable from this one.

  5. Lisa: "I created Lutherans!"

  6. upandabove says:

    Holy shit o.O I hope this isn't true :S Shit like this always happens in sci fi movies and the universe ALWAYS ends.

  7. Oh, well. It's been nice...

  8. Assuming, just for a second, that this experiment is successful and, indeed, does not destroy our space-time; will the eventual inhabitants of this new universe, assuming that there are any, come to visualize its creation as some sort of "big bang"? Or will they think it was created by some big invisible man in the sky who is white and has a long beard?

    Surely, they will never guess that their universe was created by scientists in a previously existing universe.

      He'd probably be yellow and clean shaven, actually. His long coat would be white.

      • Ah, good point. One can only imagine what sort of porn will be developed in this new universe. It will probably make sh*tting d*ckn*pples look positively normal.

      • 205guy says:

        The creator of our universe was probably also yellow and clean shaven, actually, with a long white coat. Generations of medieval monks transcribing his description and depiction gradually morphed him into the image we know. That would explain the recursivity.

    • sir_bissel says:

      ...So what I'm getting from this is we should make sure the scientists have fire crackers and white beards when they do this?

  9. Anyone else reminded of Schild's Ladder by Greg Egan?

  10. abates says:

    The bits that fill me with confidence are "if the project is successful" and "The project takes as its starting point two basic theories".

    I know they're pretty sound theories, but then so was the idea that the Sun revolved around the Earth, at the time...

  11. mjgardner says:

    If this isn't "playing God" I don't know what is.

    What the hell are you talking about, Beavis.

  13. hobbitluvin says:

    Simpsons did it.

  14. xrayspx says:

    I assume everyone reads JWZ's blog, including Japanese people, so I will use the forum to register my No vote.

    Please Don't.

    Honestly, I think that any experiment with a >0 chance of erasing everything should be approved by everyone before we do it. Kind of like how they didn't really know what atomic weapons would do to the atmosphere before they actually set one off. "whoops" is not appropriate here.

  15. ak_47 says:

    So, summing it all up, they will create something that lasts for tiniest amount of time and then "it" will just "evaporate" without any detectable trace. Meanwhile, clever Japanese physicist will fully enjoy their fat grants subsidized by ignoramus taxpayer. That's what I call being smart!

  16. 1423 says:

    Can we choose what (or who) to put in the new universe before we seal it?

  17. ahruman says:

    So, all they need to do is manipulate the (hypothetical) Higgs field and apply a (hypothetical) monopole.

    Right. Carry on, then.

  18. dzm6 says:

    Having read the comments I'm thinking the general message is:

    Dear Japanese People;

    Please stop exploring your God-like powers to create and destroy. It seems to really freak everybody else out.

    funny - i often like to think that maybe we're microscopic organisms in some sort of unremarkable test-tube universe in the high-school science laboratory of a race of Very Large Beings, and that our entire universe exists in a matter of days for them.

    i like it that we're creating our own mini universes.

  20. exiledbear says:


    Although, the fluff is easier to read and understand. From what I gather from the article, they've found a new interesting solution from the GR equations, one that says, if I'm reading them right, that stable monopoles are possible under certain conditions.

    It looks like they did computer simulations only. This is only theory at the moment, I suspect it would take a very expensive particle accelerator to try to see if this theory is correct or not. Something like the Cern LHC, perhaps.

    I can't wait for Nano-godzilla.

    Talk about overcompensating for not being able to give birth...

    • belgand says:

      That's not a bug, that's a feature.

      The idea of my giving birth fills me with horror. I can't imagine wanting to do something like that to my body.
