Scientists recently debated wormholes in a study and noticed that wormholes collisions could be detected by listening to the gravitational echoes they emit. But, in theory, many of the known black holes might, in fact, be wormholes.
The majority of known black holes present an event horizon, the point of no return beyond which nothing escapes. However, this is contradicting the quantum mechanics laws which theorized that everything is conserved, not lost, as reported by the NextBigFuture.
In theory, on the other hand, this contradiction can be tackled by the hypothesis that the vast majority of the black holes the astronomers observed are not black holes but a sort of Exotic Compact Objects, also dubbed as ECOs, which could be wormholes which don’t present an event horizon.
Wormholes collisions might be detected by the gravitational echoes they emit
Scientists from the KU Leuven University, headed by Professor Thomas Hertog, came up with a model to ease up the detection of wormholes collisions by using identifying the gravitational waves that such collisions would release.
In the cases of black holes, the gravitational waves signals vanish in a short period due to the existence of the event horizon. However, in the absence of an event horizon, as in the cases of wormholes, the signals will not extinguish after a while but would turn into a sort of gravitational echoes which are quite undetectable and could quickly go unnoticed without a suitable model for detecting them.
“Wormholes do not have an event horizon but act as a space-time shortcut that can be traversed, a kind of a very long throat that takes us to another universe. And the fact that they also have rotation changes the gravitational waves they produce,” explained the scientists.
The scientists came up with a model to reconstruct the gravitational echoes from the fundamental gravitational waves signal to make detect wormholes collisions.
