A leading Harvard astrophysicist has spoken out on the realities of space travel in an assessment of how likely it is aliens have been on our doorstep.
Avi Loeb joined Patrick Christys on GB News to discuss the Milky Way and how extraterrestrial lifeforms would be able to travel through it.
It comes as the rising tide of UFO sightings becomes more mainstream, with NASA launching its Unidentified Anomalous Phenomena Independent Study in 2022.
Loeb outlined a theory on how extraterrestrial life would be able to make their way through the galaxy.
Avi Loeb says travelling the Milky Way from one side to the other would take a billion years

“It would take about a billion years to cross from one side of the Milky Way galaxy to the other”, he said.
“Given that, I don’t think any spacecraft that would arrive to us from another star would carry biological creatures.

“They wouldn’t survive the journey, being bombarded by very energetic particles in interstellar space for so long.
“It’s more likely, if they are autonomous, they have an artificial brain. Artificial intelligence.
“We have already developed that on earth, we haven’t launched it to space but that would be the next step.”
Loeb said the US Government needs to be more transparent with its findings in order to assist the UFO research.
He called on authorities to disclose any more information it has, with scientists around the world on hand to assist.
“The government monitors the sky for national security purposes”, he said.
“Whereas scientists, astronomers for example, look at small regions of the sky at very distant sources of light.
“If something flies overhead, astronomers ignore it. If there is something over there, it’s the government that would be the first to notice it.”
Loeb added that he is “waiting” for evidence, and the government must disclose what it knows for strides to be made in the field.
“As a scientist, I respond to evidence”, he said.
“That’s what we are waiting for. The government to disclose what it knows.
“It’s really important for me because I’m trying to find the evidence myself, but the government can save me a lot of time.
“Why should I spend decades of my life looking for something when the government already has it?”
