Each red speck represents a universe within the multiverse, appearing and then disappearing again

Researchers at the University of Maryland, College Park and Towson University are reporting that they have created multiple universes inside a laboratory-created multiverse — a world first.

To be exact, the researchers created a metamaterial — like those used to fashion invisibility cloaks — that, when light passes through it, multiple universes are formed within it. These universes, called Minkowski spacetimes, are similar to our own, except they more neatly tie up Einstein’s theory of special relativity by including time as a fourth dimension.

While this is rather extraordinary, the experimental setup is actually quite simple — though definitely rather unconventional. The multiverse is created inside a solution of cobalt in kerosene. This fluid isn’t usually considered a metamaterial, but lead researcher Igor Smolyaninov and co found that by applying a magnetic field, the ferromagnetic nanoparticles of cobalt line up in neat columns. When light passes through these columns, it behaves as if it’s in a Minkowski universe.

Experimental setup, for creating a multiverse

To create multiple universes, the researchers fine-tuned the amount of cobalt in the fluid until there wasn’t quite enough to form the nanocolumns. Natural variations in the fluid mean that some regions still have enough cobalt to form the columns, and thus new universes. As the fluid moves the columns collapse, multiple universes constantly pop in and out of existence.

There are two key takeaways here: First, metamaterials are usually rather hard to manufacture — and yet here the researchers have seemingly discovered a self-organizing metamaterial. Second, this is the first ever time that new universes have been created in a laboratory setting. This is about as bleeding-edge as it gets, so we’re not exactly sure what avenues of research this opens up, but Smolyaninov suggests that they could be used to study how particles behave in universes with different properties than our own. Our universe has fairly firm rules on how particles behave, but it might be interesting to create a pet universe where, say, photons have mass and light travels really slowly.

  1. Vorrei creare una connessione wifi dal pc ( vorrei cioè usare il mio portatile con windows xp come router ) senza però che il computer sia connesso al wifi ma solo tramite la connessione ethenet. E’ possibile?

  2. ciao a tutti, volevo sapere quali fossero i college degli Stati Uniti che partecipano al campionato NCAA….
    cioè vorrei una lista( cn i nomi dei college e lo stato) che partecipano al campionato di basket NCAA

    grazie mille 10 punti al + veloce e completo grazie

  3. Io ho la versione a pagamento eppure non riesco ad’ entrare nei server che creo. Quale potrebbe essere il problema? Quali settaggi vanno messi nel “Server Properties”?
    Ce un altro mio amico con versione SP con qui vorrei giocare ma nemmeno lui riesce a creare il server a modo.

  4. Quando mi iscrivo x scaricare giochi x l’iPod touch devo creare un Apple ID ma andando avanti con le domande arrivo a un punto dove viene richiesto un “metodo di pagamento” quindi puoi scegliere tra varie carte di credito inserire numero e codice. Se io non voglio inserire questi dati come faccio a crearmi un Apple ID??

  5. Vorrei creare dei laboratori didattici per bambini e ragazzi delle scuole primarie e secondarie, ma non riesco a trovare da nessuna parte informazioni utili relative a una normativa che regoli le competenze di un singolo o un’associazione.
    Qualcuno sa dove posso cercare, oppure a chi mi devo rivolgere? Chi ha esperienze del genere????
    @Volevo aggiungere che vorrei creare questo laboratorio da esterna, non lavorando all’interno di una scuola.
