Dit is ons nieuw hondje Kira, een kruising van een waterhond en een Podenko. Ze is sinds 7 februari 2024 bij ons en druk bezig ons hart te veroveren. Het is een lief, aanhankelijk hondje, dat zich op een week snel aan ons heeft aangepast. Ze is heel vinnig en nieuwsgierig, een heel ander hondje dan Noleke.
This is our new dog Kira, a cross between a water dog and a Podenko. She has been with us since February 7, 2024 and is busy winning our hearts. She is a sweet, affectionate dog who quickly adapted to us within a week. She is very quick and curious, a very different dog than Noleke.
DEAR VISITOR,
MY BLOG EXISTS ALREADY 12 YEARS AND 9 MONTHS.
ON 06/03/2024 MORE THAN 1.940.230
VISITORS FROM 134 DIFFERENT NATIONS ALREADY FOUND THEIR WAY TO MY BLOG.
THAT IS AN AVERAGE OF 400GUESTS PER DAY.
THANK YOU FOR VISITING MY BLOG AND HOPE YOU ENJOY EACH TIME.
The purpose of this blog is the creation of an open, international, independent and free forum, where every UFO-researcher can publish the results of his/her research. The languagues, used for this blog, are Dutch, English and French.You can find the articles of a collegue by selecting his category. Each author stays resposable for the continue of his articles. As blogmaster I have the right to refuse an addition or an article, when it attacks other collegues or UFO-groupes.

Deze blog is opgedragen aan mijn overleden echtgenote Lucienne.
In 2012 verloor ze haar moedige strijd tegen kanker!
In 2011 startte ik deze blog, omdat ik niet mocht stoppen met mijn UFO-onderzoek.
BEDANKT!!!

Verder heb je ook het Belgisch-Ufo-meldpunt en Caelestia, die prachtig, doch ZEER kritisch werk leveren, ja soms zelfs héél sceptisch...
Voor Nederland kan je de mooie site www.ufowijzer.nl bezoeken van Paul Harmans. Een mooie site met veel informatie en artikels.
MUFON of het Mutual UFO Network Inc is een Amerikaanse UFO-vereniging met afdelingen in alle USA-staten en diverse landen.
MUFON's mission is the analytical and scientific investigation of the UFO- Phenomenon for the benefit of humanity...
Je kan ook hun site bekijken onder www.mufon.com.
Ze geven een maandelijks tijdschrift uit, namelijk The MUFON UFO-Journal.
Since 02/01/2020 is Pieter ex-president (=voorzitter) of BUFON, but also ex-National Director MUFON / Flanders and the Netherlands. We work together with the French MUFON Reseau MUFON/EUROP.
ER IS EEN NIEUWE GROEPERING DIE ZICH BUFON NOEMT, MAAR DIE HEBBEN NIETS MET ONZE GROEP TE MAKEN. DEZE COLLEGA'S GEBRUIKEN DE NAAM BUFON VOOR HUN SITE... Ik wens hen veel succes met de verdere uitbouw van hun groep. Zij kunnen de naam BUFON wel geregistreerd hebben, maar het rijke verleden van BUFON kunnen ze niet wegnemen...

Do Black Holes Die?
Do Black Holes Die?
By Paul Sutter, The Ohio State University
There are some things in the universe that you simply can't escape. Death. Taxes. Black holes. If you time it right, you can even experience all three at once.
Black holes are made out to be uncompromising monsters, roaming the galaxies, voraciously consuming anything in their path. And their name is rightly deserved: Once you fall in, once you cross the terminator line of the event horizon, you don't come out. Not even light can escape their clutches.
But in movies, the scary monster has a weakness, and if black holes are the galactic monsters, then surely they have a vulnerability. Right?
Hawking to the rescue
In the 1970s, theoretical physicist Stephen Hawking made a remarkable discovery of a secret buried under the complex mathematical intersection of gravity and quantum mechanics: Black holes glow, ever so slightly, and given enough time, they eventually dissolve. [Hawking Wants to Power Earth With Mini Black Holes: Crazy or Legit?]
Wow! Fantastic news! The monster can be slain! But how? How does this so-called Hawking radiation work?
Well, general relativity, which describes how gravity behaves, is a supercomplicated mathematical theory. Quantum mechanics is just as complicated. It's a little unsatisfying to respond to "How?" with "A bunch of math," so here's the standard explanation: The vacuum of space is filled with virtual particles, little effervescent pairs of particles that pop into and out of existence, stealing some energy from the vacuum to exist for the briefest of moments, only to collide with each other and evaporate, returning to nothingness.
Every once in a while, a pair of these particles pops into existence near an event horizon, with one partner falling in and the other free to escape. Unable to collide and evaporate, the escapee goes on its merry way as a normal nonvirtual particle.
Voilà! The black hole appears to glow as particles and radiation escape. In doing the work to separate a virtual particle pair and promote one of them into normal status, the black hole gives up some of its own mass. Subtly, slowly, over the eons, black holes dissolve. Not so black anymore, huh?
Here's the thing: I don't find that answer especially satisfying, either. For one, that explanation does not appear in Hawking's original 1974 paper which unveiled the process, and for another, it's just a bunch of jargon that fills up a couple of paragraphs but doesn't really go a long way in explaining this behavior. It's not necessarily wrong, just … incomplete.
Let's dig in. It'll be fun.
The way of the field
First things first: "Virtual particles" are neither virtual nor particles. In quantum field theory — scientists' modern conception of the way particles and forces work — every kind of particle is associated with a fieldthat permeates all of space-time. These fields aren't just simple bookkeeping devices; they are active and alive. In fact, they're more important than particles themselves. You can think of particles as simply excitations — or "vibrations" or "pinched-off bits," depending on your mood — of the underlying field.
Sometimes, the fields start wiggling, and those wiggles travel from one place to another. That's what we call a "particle." When the electron field wiggles, we get an electron. When the electromagnetic field wiggles, we get a photon. You get the idea.
Sometimes, however, those wiggles don't really go anywhere. They fizzle out before they get to do something interesting. Space-time is full of the constantly fizzling fields.
What does this have to do with black holes? Well, when one forms, some of the fizzling quantum fields can get trapped — some permanently, appearing within the newfound event horizon. Fields that fizzled near the event horizon end up surviving and escaping. But due to the intense gravitational time dilation — which says that the faster you travel, the more time seems to slow down — near the black hole, they appear to come out much, much later in the future. [8 Ways You Can See Einstein's Theory of Relativity in Real Life]
In their complex interaction and partial entrapment with the newly forming black hole, the temporarily fizzling fields get "promoted" to become normal, everyday ripples — in other words, particles.
So Hawking radiation isn't so much about particles popping into existence near a present-day black hole, but rather the result of a complex interaction at the birth of a black hole that persists until today. You can think of that complex interaction as preventing the black hole from ever growing to its maximum possible extent — even at its birth it was doomed to disappear.
Patience, child
One way or the other, as far as we can tell, black holes do dissolve. I emphasize the "as far as we can tell" bit because, as I said at the beginning, generality is all sorts of hard, and quantum field theory is a beast. Put the two together, and there's bound to be some mathematical misunderstanding.
But with that caveat, we can still look at the numbers, and those numbers tell us we don't have to worry about black holes dying anytime soon. A black hole with the mass of the sun will last a wizened 10^67 years. Considering that the current age of our universe is a paltry 13.8 * 10^9 years, that's a good amount of time. But if you happened to turn the Eiffel Tower into a black hole, it would evaporate in only about a day. I don't know why you would, but there you go.
