UFO = (Unidentified Flying Objects).
They may fly, they may be unidentified and they may be objects. I have no problem with that.
However, they are NOT from outer space. Take a bit of time to study some physics and you’ll agree! If you don’t know the physics, you can’t possibly know the truth.
Lots of assumptions in your post.
I know enough about Physics to know they are not inter-galactic, but more inter-dimensional.
“They may fly, they may be unidentified and they may be objects. I have no problem with that.”
I think they could be natural Earth phenomen such as lighting that is finally being seen for various reasons..or a new form of natural animal species from deep in the ocean or let out by ice melting.
Maybe the reason they are attracted to military ships is the strange sounds or frequencies only those ships put out.
You're the one who doesn't know physics.
Objects cannot accelerate to the speed of light within normal spacetime; instead, the Alcubierre drive shifts space around an object so that the object would arrive at its destination more quickly than light would in normal space without breaking any physical laws.[3]
One of many proposed approaches to manipulate space-time.
