I am curious how those who believe aliens are visiting us think they have overcome the speed of light limitations of travel throughout the universe . Given that it would take dozens to hundreds of years to travel even one way from our nearest neighbors unless this limitation is overcome , and the same to return home with whatever info they have gleaned from their visit , how are they getting around this quickly ? And given that the energy needed to approach the speed of light becomes enormous as you reach any meaningful percentage of the SoL , how are they powering themselves for decades long trips? And feeding themselves on these long long journeys ?
I’m just curious how those who believe this is happening have worked out the necessary logistics for hundreds of millions of MPH trips 24/7/365 nonstop for dozens of years .

Einstein's theory of relativity is one of the few theories that has never met with any serious arguments/observations/experiments against it. As you know, the speed of light can never be acieved by matter, but nothing says it can't be approached closely....Let's say these super aliens can solve the energy problems involved with getting their saucers to go that fast, includng the problem of time to accellerate to & decellerate fom flying near "c".....
...Don't make the mistake of assuming "they" experience time & aging & gravity (physiological problems associated with acelleration/decelleration) the way we do. A flight of 100 yrs may not be a problem to them.
BTW- if they're smart enoygh to solve all these problems and to get here, maybe we should be hiding from them, not actively trying let them know we're here.

Also consider the possibility that the visitors may have transcended biology. Machine intelligence may not care if they had to remain in a high speed vessel for hundreds or thousands of years.

Anything remotely close to c is basically unattainable from a pure energy perspective. The amount of energy needed to keep accelerating to c approaches infinity at anything around 90% of c . Take even travelling at 50% of c . By the time you accelerate to 50% of c and then decelerate near Earth, you're talking a 10 yr one way trip from the nearest star to us. So 20 yrs to return home with any results from your trip. The energy required for this would be enormous. Rounding off a little, the energy required to move the ISS to 50% c would be the equivalent of 29,600,000 Hiroshima bombs . For the trip here. Then that much again to go home. Provided no pit stops are made on the way coming or going that require reaccelerating. So you invest the energy of 60,000,000 Hiroshima bombs* to spend 20 years in space to come take a peek at some humans on Earth. And we haven't touched on nourishment supplies. Or zipping through space at 335,000,000 MPH and how you deal with getting hit by space dust at 335,000,000 MPH. Or how you avoid asteroids or even planets at that speed. How do you steer a spaceship moving at 335,000,000 MPH? What are the g forces on a living being inside a spaceship at 50% c when it has to veer course around objects?
As to the last paragraph, to steal from Star Trek, humans would compare to a species capable of regularly and routinely pulling this off as single celled amoeba would compare to humans.
And we havent dealt with travel from the more likely locations of 100s light yrs or more away. We would likely have picked up some sort of signal from any advanced civilization within close range of Earth. So travel to and from here even at the improbable to achieve 50% c would be closer to 1000 year round trips.
All just to kidnap and experiment on us
* Probably more . A lot more . This just calculates acceleration for each side of the trip, and not the energy required to decelerate twice . Maybe closer to 100,000,000 Hiroshima bombs per trip .

On the other hand, maybe they are already here, settled and living in the deep oceans, very cold places and beneath the Earth.
If these sightings of craft can be believed, then they have the ability to enter water without any splash which suggests a transmedium ability. That means they can go through any material - water, earth, space without any change in speed. So...why not have a base under the ocean or under the Earth/ice/etc ? Our history - in the language of the time, has documented sightings for thousands of years.
After all, many sightings and reports from submarines (US and Russian) have also been seen under the oceans and in remote places.

Have you ever seen the movie 'Midnight Special'?
Its a movie about this weird kid who has supernatural abilities and his parents are trying to hide him from the CIA...
At the end of the movie, it depicts 'where' he is from...its on this planet, but its kind of like another dimension, but they are aware of us. I think this depiction is spot on, on where these UFOs come from, the movie is good too.

There’s always the possibility they have discovered “different and interesting” new physics that allow for FTL travel. We can’t imagine it at our current level of development, but neither could the director of the patent office at the turn of the 19th century imagine space flight, larger commercial aircraft etc when he famously said (paraphrasing here…) that everything that could be invented, has been invented. Wow was he ever wrong.

Speed of light limitations ARE physics . There is a difference between not having the imagination to grasp the implications of physics and inventing new physics . Laws of Physics are not invented , they are discovered, and can’t be altered .

Nice, you’ve got everything firmly grasped and figured out. I guess we’re done here?

To be clear: I don't believe aliens are visiting us. I don't necessarily disbelieve it either. I have yet to see any evidence that convinces me they are. But I'm willing to admit it's possible. So ... how might it be possible?
I think the most likely explanation is that more advanced civilizations have found a better way to travel rather than simply going from Point A to Point B really fast. Because you're right. Even going at the speed of light (which may not be possible), it would still take hundreds of years to traverse the stars.
So maybe more advanced civilizations have found other ways of traveling? Our own scientists are already beginning to postulate ways that might be possible.
Another possibility ...
It is possible that it is actually possible for matter to travel faster than light. We just haven't figured out how yet. Don't get me wrong. I think the current science that says this isn't possible seems sound. But it is based on what we know now. Are we really so arrogant as to think we have all the universe figured out? If the laws of the cosmos were all written out in a hundred trillion libraries, each containing a hundred trillion books of a million pages each, I'd guess we have probably made our way through the first few chapters of one book.
