The recent UFO sightings by military pilots

It amuses me when some take OUR perceived laws of physics and try and apply them to a completely different degree of knowledge the travelers would possess. There are many ways to vector away from what we THINK we know about physics and any visitors.. What if they never traveled that far at all, and have been here much longer than us. The "Black knight" satellite has been in a north south AND east west orbit for an estimated 13 K yrs. Seen and mentioned by astronomers all over the world. We might be the new kids on the block.

Now Jesus exists.

not everyone has a consciousness

In my opinion that is what religion is all about.

Most will probably turn out to be "our" top-secret technology.

I would think if we possessed this great technology, we would use it.

That sounds good, If you ever stand before a creator, tell him he’s a phoney a fraud, and he’s a jackass. I hope that works for you.

Its probable that some aliens are more advanced then we are as their stars are much older. But the physics doesn't change. The speed limit is the speed of light, and the distances are vast.

” the physics doesn’t change” that’s the arrogance I’m talking about. I think it would be more accurate to say, the physics as we understand it. Many things are invisible to the naked eye, just because we can’t see them doesn’t mean they don’t exist. I’m wondering if people were thinking about radios, television, cell phones, jet propelled aircraft 2000 years ago. Today that is just technology. I wonder where technology will be 2000 years in the future.

I would say that faster than light speed travel, in a conventional way, is limited by physics. But that does not rule out other methods. Considering that we can’t figure out what 68% of the energy and 27% of the matter is in the universe (dark energy and matter) I am sure there are many things to discover in this area. As for whether there is alien life out there the answer is yes, given the the probabilities over the size of the universe. The real question is whether intelligent life can survive long enough and avoid exterminating themselves, to achieve interstellar travel.

I’ve read a bunch of pros and cons and quantum physics science briefings. I’m thinking most of it is above my pay grade. I would guess if they are like humans they probably will destroy them self long before. Your last comment got me laughing pretty hard, I know it’s not funny and it’s sad but it’s true.

Yes, the Fermi Paradox, The Great Filter and the We’re F#cked scenario make you believe it may very well be impossible for a civilization to progress far enough to venture out into the galaxy. If you guys are inclined here’s a good summation https://waitbutwhy.com/2014/05/fermi-paradox.html

your a joke

You believe anything

That's why your rump fan

[FMP]

It's really quite simple, we achieve the speed of light and turn on the high beams

Yaaaa.... Yahhhaaaa.....

Ya gotta shoot them from the rear deck.....with a shotgun.....jusy amim' and Fire ......

Don't forget the Socks in the Dryer Paradox.

We do eventually use the technology, we had a jet-powered "flying wing" prototype flying up and down the coast of California in 1947... that eventually became the B2 stealth bomber in what, 1990?

[David - WI]

If we are being visited it makes sense that what we are seeing are probes.
Why would you send a manned craft to gather data.

Not to mention the time it takes for a craft to get here at an astronomical cost.

"In short, achieving the speed of light is impossible, never mind exceeding it. So barring some tremendous revolution in our understanding of physics, a Faster-Than-Light (FTL) propulsion system can never exist.

Such is the consequence of living in a relativistic Universe, where traveling at even a fraction of the speed of light requires tremendous amounts of energy.

And while some very interesting and innovative ideas have been produced over the years by physicists and engineers who want to see interstellar travel become a reality, none of the crewed concepts are what you might call "cost-effective."

Specifically, the concept of Fusion Propulsion was investigated by the British Interplanetary Society between 1973 and 1978 as part of a feasibility study known as Project Daedalus.

The resulting design called for a two-stage spacecraft that would generate thrust by fusing pellets of a deuterium/helium-3 in a reaction chamber using electron lasers.

This would create a high-energy plasma that would then be converted to thrust by a magnetic nozzle.

The first stage of the spacecraft would operate for just over 2 years and accelerate the spacecraft to 7.1 percent the speed of light (0.071c). This stage would then be jettisoned and the second stage would take over and accelerate the spacecraft up to about 12 percent of light speed (0.12c) over the course of 1.8 years.

The second-stage engine would then be shut down, and the ship would enter into a 46-year cruise period.

According to the Project's estimates, the mission would take 50 years to reach Barnard's Star (less than 6 light-years away). Adjusted for Proxima Centauri, the same craft could make the trip in 36 years.

But in addition to technological barriers identified by the Project, there was also the sheer costs involved.

Even by the modest standard of an uncrewed concept, a fully-fueled Daedalus would weigh as much as 60,000 metric tons cost over [US$5.2 trillion] (based on 2012 estimates). Adjust to 2020, the price tag for a fully-assembled Daedalus would cost close to US$6 trillion. Icarus Interstellar, an international organization of volunteer citizen scientists (founded in 2009), has since attempted to revitalize the concept with Project Icarus.

Marconi made the first radio transmission in 1897... that thing that fell out of the sky in Roswell was 50 years later, in 1947.
