A good portion of the lightning I see is not associated with thunder. Very typical in and around the med While it does have flashes some of it consists of "pulsating" "clouds" with no noise associating. Eerie glows. Initially very strange if you have only previously experienced the classic flashes and blots of lightening with deafening thunderclaps.
Your first comments are based on current human technology (as far as we know...), as well as on our life-spans. If there is other life "out there", we do not know what technology they have (as you have suggested yourself, which I've highlighted), nor do we know how long they live, etc.. So, while we humans from earth certainly can't drop in on the nearest planet for a visit, we cannot assume that nobody else can.Grasshopper wrote: ↑Thu Apr 11, 2019 1:44 pmThere aren't any UFOs or ETs. If you look at it logically the nearest planet to Earth that can possibly support life is about 15 light years away. The fastest we can travel through space is reckoned to be about 1/10th the speed of light - so it would take 150 years for an alien to get here. So it would be dead. Unless of course they've found a way to travel faster than light....
Broadly yes. But bear in mind that human travel to Mars (which is about 12 light minutes away) is beyond our current technology - and probably beyond what the human body can stand. So 12 light years is completely impossible. Also bear in mind that the kinetic energy of a body is proportional to the square of its velocity. Even at 1/10th the speed of light the dangers of a collision with space debris are large. Even hitting a grain of sand at that speed can do severe damage. At the speed of light - well you'd need a new space craft at the very least.
I've never said there isn't. In fact, if the universe is indeed infinite then it's a certainty. My point is simply that the sheer size of the universe means that we'll never meet - even in the unlikely event that we both exist over the same time period.
Newtonian physics breaks down even in our own universe - it only works acceptably on medium scale bodies (i.e. on Earth). When you get to the planetary scale we use Relativity, which so far works as accurately as we can measure. But Relativity breaks down on the very small scale (elementary particles) where Quantum theory is used. Horses for courses. However, so far, it seems that the whole of OUR universe works to the same rules as our own and all bodies are made of the same elements - which we can tell by spectroscopy.kirolak wrote: ↑Thu Apr 11, 2019 6:20 pmPerhaps Newtonian physics doesn't apply in other universes. . . .perhaps by travelling close to the speed of light one enters a different time-stream. . . perhaps another dimension. . .perhaps other life forms are not carbon based . . perhaps "aliens" are not physical at all as we know it. . .

When I was young, I read a ton of science fiction, read books on Astronomy, read Sky and Telescope magazine, and decided to study Astronomy and Astrophysics formally. I looked up in the sky constantly. If anyone saw an extraterrestrial, * I * wanted to be the one to see it. I wanted to go to Mars.
Well, every time I looked up, saw a fireball, a glow, a light moving through the sky....I knew what it was I was looking at.
No UFOs for me. I’m still waiting to look up and see something I don’t recognize. I have fielded calls from people who call observatories when they see something...and still nothing that is unidentifiable.
PS, I did a lot of work during the design and building phase of the Large Millimeterwave Telescope (LMT) they used in Mexico for that black hole experiment, and my husband helped with the instrument used on the telescope for that experiment.
We were so happy to see the results come out!
Cast of thousands, as they say.
