Black holes remain one of the most mysterious astronomical entities. For years scientists have believed that one hits a "firewall" upon being sucked in, and any kind of matter is immediately destroyed.

A new paper however challenges this theory, stating that upon entering a black hole, one becomes a hologram.

Stephen Hawking proved that black holes are first of all, not really black, and second, that they continue to emit quantum radiation throughout their existence. This is a paradox however, as even quantum matter cannot fully disappear without existing in another state. So if a black hole is disappearing, where does it really go?

There is the fuzzball theory, proposed by Samir Mathur, stating that black holes do not have a definitive event horizon, or barrier. Firewalls on the other hand destroy everything that enters into them.

Using holography, a technique applied to understanding string theory, there is distinct possibility that matter entering into a black hole becomes a hologram of its three dimensional existence.

By synthesizing Einstein's theory of gravity with existing theories of how black holes are formed and maintained, one possibility is that matter entering the black hole can be understood two dimensionally, as a hologram.
