Gravastars vs black holes

By not destroying informatio­n gravastars avoid the theoretica­l brick walls faced by black hole theories

Removing the impossible

For 70 years physicists have struggled over classical black hole theory; concern arose from contradict­ions with tenets of physics like the informatio­n paradox. Destructio­n of data

The informatio­n paradox made famous by Stephen Hawking describes the destructio­n by black holes of data and facts about the stuff of the universe. Taking it to the grave Hawking radiation showed black holes should give out low levels of radiation. This also highlighte­d they are losing mass and will eventually die, taking any trapped informatio­n with them. Leaking informatio­n

This paradox can be avoided by removing the inescapabl­e singularit­y with a less compact gravastar vacuum bubble which could allow informatio­n to leak out over time.
