Press unleashed in these days for the work of the Federico II University of Naples. Scientists have managed to reproduce a wormhole, that is a space-time bridge. The result of the Neapolitan study has stimulated the imagination of many people, even going so far as to hypothesize time travel within a few years. But what are wormholes? And will it really be possible to travel through time?
What is a wormhole?
When we talk about wormholes we are talking about a way to bend spacetime. Hypothesized by Albert Einstein e Nathan Rossen in 1933 (in fact it is also known as Einstein-Rossen bridge), the wormhole is a shortcut that would allow us to cover huge distances in no time.
Imagine the universe as a sheet of paper or a tablecloth: to get from one end to the other we will be forced to cross its entire surface. However, if we managed to fold that sheet in two, it would be possible to make a hole to get to its destination immediately. That hole is our wormhole, and it would allow us to move in space by breaking down distances with the use of very few resources.
Obviously this is a rough definition, and even today very little is known about these wormholes. Scientists are asking themselves thousands of questions, and according to some, our own galaxy could be a gigantic wormhole.
The work of Federico II
The team of scholars, led by Salvatore Capozziello, recreated a laboratory model of the Einstein-Rossen bridge. However, the work of scientists rather than cosmology interests the world ofelectronics. Starting from the theoretical foundations on wormholes, the researchers were able to link gods together graphene sheets, the thinnest material in the world. The connection took place with a nanotube in which the currents travel in an extremely precise manner as soon as it is activated. All thanks to those astrophysical theories developed on space-time bridges.
This could (the conditional is a must) allow the realization of superconductors in graphene on an industrial scale. A historic milestone for the world of electronics, given that we have been trying to achieve it for decades.
But can this study block the path to space-time travel? As previously said, we are not talking about cosmology, but about astrophysical theories applied in other sectors.
One of the greatest mysteries of the universe is currently represented by gravity: a phenomenon studied for centuries and with an unknown number of questions still to be solved. It is also necessary to understand if it will be possible to travel, and in what way, inside a wormhole. In short, until all the answers are found, let's put our hearts in peace. For now, let's be satisfied with the space-time travels of the series Stargate.
