It makes up three quarters of what is in the universe. It stretches space – time like a normal piece Le jour o— mon petit frŠre a ‚t‚ plus grand que moi je me suis dit Shirt of rubber. And it is of interest to power generation researchers. It is the dark energy, the greatest mystery of matter.
Dark energy is everywhere MERRY CATMAS Christmas Sweatshirt Christmas Jumper , Cat lover christmas, funny christmas Cat Shirt in the universe. It can make entire galaxies move, but can’t see it! In early 1998, researchers discovered that the universe was expanding too quickly. An unexpected result. Certainly about 15 billion years ago, at the time of the big bang, the universe had suddenly expanded: its size increased to 1050 times in a Merry Christmas Koala Raglan Baseball Tee Shirt split second! But this terrible expansion gradually diminishes with time, under the effect of cosmic gravity (pulling the planets, stars together).
“We also have evidence of this accelerating expansion thanks to some extremely bright stars – explained Jean-Philippe Uzan, cosmologist at the Paris Institute of Astrophysics. is at the Merry Sharkmas Funny Shark Christmas Tree Funny Shark Shirt end of his life emitting an extraordinary light, illuminating the universe like a headlight. The advantage is that the light intensity of these stars is always constant. So we can use it as an effective means of measuring the distance between us and the dying star. The closer it is to us, the brighter it is ”.
Astronomers catalog a large number of these extremely bright stars, then they calculate the distance between them and the earth. “In general, extremely bright stars are typically You don’t know the power of the dark side David Prowse signature new Shirt less bright than before. That means we are further away from them than we expected. In other words, the universe has expanded faster, making the distance between the earth and the extremely bright stars increasing.
The expansion of this universe became the first evidence for the existence of a dark energy. Researchers have no choice but to invent the concept of “dark energy”, a form of “repulsive” matter (because it pushes galaxies away from each other), to explain the acceleration they observed. But it is impossible to imagine how the particles carry this energy source. Even when it comes to the most complex equations, physicists cannot answer this question. Dark energy is completely new and mysterious!
Another evidence was discovered in October 2003. This time it’s from photonic foton, light-carrying particles. American researchers were interested in photonic fotons that travel long distances through clusters of galaxies hundreds of millions of light years in diameter before they reach Earth.
Normally, the energy of a photonic foton is not affected by the path it travels. That’s the theory on paper … Actually, photonic fotons get a little extra energy from the outside! An The Pandemic That Stole Christmas Corona Virus Wear Santa Hat limited Shirt unusual thing can only be explained by the action of dark energy. It contributes to help the photonic foton escape gravity.
Speculations help scientists move closer and closer to dark energy. But still has not really proven it. While this energy source accounts for the majority of the total energy of the universe. In order to explain the hysterical escape of galaxies, it must be accepted that dark energy accounts for 70% of the energy present in our world! Yet, no probe has been able to capture it, not even in a dream.
To solve this conundrum, cosmologists have tried to determine the origin of this energy. And one of the main What The Elf Happened To 2020 Xmas limited Shirt theories is … a vacuum! To understand this kind of … energetic vacuum, imagine space like the surface of the ocean. Observed from the sky, it is flat. But a closer look, one finds that this surface consists of sunken areas and bulges. The reality is that flat surfaces are just average and dull spots create bulges.
The same goes for vacuum energy: a vacuum mass generally does not contain a single molecule. But if you look closer, the vacuum is made up of a boiling ocean of particles Teacher Besties Because Going Crazy Alone Is Not Much Santa Reindeer Christmas 2020 Shirt that appear and then destroy each other when they meet. These special particles – which the essence is not well known – can bring dark energy
The hypothesis is very attractive. Especially when dark energy is present everywhere in the universe, what sinh it must also be present everywhere. That is the case with the vacuum. Only physicists have calculated the total energy of the vacuum in the universe, to see if it is enough to explain the expansion of the universe. And they have to admit that they got into trouble. The calculated result is 10,120 times higher than the calculated value of astronomers. The conclusion is hard to convince: physics seems to be at a dead end, at least for the moment
