It feels like one of the most unanswerable questions out there but one Harvard University professor believes that aliens could well exist - and if they do then their technology would have a seismic effect on humanity.

Professor Loeb suggested that extraterrestrials may be much further along than us Earthlings, claiming they could have been working on dimension-hopping technology for billions of years already. The professor also said that if alien technology was able to reach us then we’d be in complete awe because it would be beyond what we on Earth currently have.

Researchers at CERN, which is 100 metres underground, have looked for six ‘extra spatial’ dimensions and certain particles in particular that such dimensions exist.
