What lies beyond all we can see? The question may seem unanswerable.

Nevertheless, some cosmologists have a response: Our universe is a swelling bubble. Outside it, more bubble universes exist, all immersed in an eternally expanding and energized sea — the multiverse.

Since they can’t prod actual universes as they inflate and bump into each other in the hypothetical multiverse, physicists are studying digital and physical analogs of the process.

The idea is polarizing. Some physicists embrace the multiverse to explain why our bubble looks so special (only certain bubbles can host life), while others reject the theory for making no testable predictions (since it predicts all conceivable universes).

But some researchers expect that they just haven’t been clever enough to work out the precise consequences of the theory yet.

While scientifically-designed human organs may sound like science fiction, many labs across the world are hoping to one day make them reality.

Before an organ can be made in a lab however, researchers say there are two major hurdles to overcome.

The first is creating a biologically compatible 3D scaffold in which cells can grow. The second is triggering cells to grow into the desired organ or tissue.

The researcher's new approach uses a near infrared laser to trigger proteins to stick to a scaffold made from collagen.

The researchers were able to create any shape they wanted from the laser-created proteins.
