Have We Already Been Visited by Aliens?

 

With official government investigation into reputed "unidentified anomalous phenomena" (UAPs), the idea of extraterrestrial connections has never been closer — but alas, there are major logistical obstacles present for any aliens seeking to swing by.

In interviews with us about the nitty gritty of alien probes, space specialists from schools in New York and California mentioned a core stress to seek for intelligent life. On one side, life on Earth has been discoverable from distant for a very long time. On the other, there are all types of pesky physics actualities that would make it remarkably hard to send a probe here in real.

"Earth has had biosignatures for 3 billion years," University of Rochester astrophysics professor Adam Frank told the outlet. "If such things as space-faring civilizations, it is not possible that somewhere in those 3 billion or 4 billion years that somebody visit through, or somebody sent probes."

But, he informed, unless ETs detect improbable new rules of physics that assist them travel more fast than the speed of light, master the kind of "wrap-drive" tech seen in sci-fi films, or successful in reaching till wormholes, the long distance would be an hurdle beyond belief.

"Anything moving faster than light is currently a science myth because the laws of physics say that it is not possible" Frank told the magazine. "Speed of light is as fast as you’re gonna go."

And Scott McCormack, an assistant professor of engineering and material science at the University of California, Davis said that even if alien civilizations could find how to go faster than light speed, they'd still have to face all that space debris that would hit their crafts in the way.

According to the reasoning of the UC Davis scientist, whose expert in materials that can tolerate ultimate circumstances like those in space, ETs would require spaceships as solid as — or harder than — diamonds, and far more long lasting.

"To compress these effects, you must have a material that’s going to have both solidness [to prevent being deformed] and high fracture perseverance," McCormack said. "What substance could that be? I don’t think we have any thing like that yet."

But along with the time, like Frank said, you'd assumed that if anyone was present there, there's a possibility they would have both detected our planet alone and sent something to go and inquire. So, the consensus looks to be, it's worth it to keep seeking.
