Black holes are gravitational behemoths that dramatically twist space and time. Recently, they’ve also pointed researchers to a remarkable proposal—that everything we see may be akin to a hologram.

In this World Science U Live Session, Nobel laureate, former Director of the National Institutes of Health and former President of Memorial Sloan Kettering, Harold Varmus, M.D., and Brian Greene …

Extra dimensions of space — the idea that we are immersed in hyperspace — may be key to explaining the fundamental nature of the universe. Relativity introduced time as the fourth dimension, and Einstein’s subsequent work envisioned more dimensions still — but ultimately hit a dead end.

Powerful new genetic tools allow scientists to alter the DNA of any organism—with tests on human embryos already underway. Even more ambitious, synthetic biologists on the verge of creating the genetic material for a living organism from scratch are setting their long-term sites on fashioning a fully synthetic human genome.

As computers become progressively faster and more powerful, they’ve gained the impressive capacity to simulate increasingly realistic environments. Which raises a question familiar to aficionados of The Matrix—might life and the world as we know it be a simulation on a super advanced computer?
