"After the discovery of the supernova, astronomers predicted that they would be able to see it again in about one year... HST observations of MACS J1149. 5+2223 taken on 11 December 2015 show an object interpreted as a new image of SN Refsdal. This was the fifth image of SN Refsdal and—importantly—the first time astronomers successfully predicted the appearance of a supernova image. "

"An international team of scientists working with the Dark Energy Spectroscopic Instrument known as Desi has published the results of their monumental research on the evolution of the cosmos using baryonic acoustic oscillations. When these extremely accurate maps of cosmic structures were combined with those known from cosmic microwave background radiation and traditional supernovae, scientists obtained a clear and unambiguous signal. Dark energy is not a constant value. "

"Multiply lensed images of a same source experience a relative time delay in the arrival of photons due to the path length difference and the different gravitational potentials the photons travel through. This effect can be used to measure absolute distances and the Hubble constant ( H 0 ) and is known as time-delay cosmography. The method is independent of the local distance ladder and early-universe physics and provides a precise and competitive measurement of H 0 . "

"In a typical crystal, all atoms are trapped in their positions in a three-dimensional lattice. In the superionic state, something unusual happens. One type of atom behaves rigidly, forming a stiff scaffolding with an intact spatial structure. But the second type of atom, trapped in the free spaces of this lattice, gains such enormous energy that it breaks all bonds and begins to rush between the elements of that scaffolding with complete, almost chaotic freedom. These lighter elements become a true liquid river inside the solid crystal. "

"When a star runs out of hydrogen in its core, the aforementioned hydrostatic equilibrium ends. Without energy from fusion preventing gravity, the core begins to collapse, and the collapse causes an extreme increase in pressure, which in turn raises the temperature. Eventually, the core becomes so hot that it initiates Helium fusion, introducing the star into a completely new stage of evolution. But this giant temperature also heats the outer layers of the object. They reach thermal levels that previously only existed in the center. Suddenly, hydrogen atoms in the outer shells gain the ability to fuse. This powerful new energy source forces the star to dramatically expand. The object becomes a red giant. "

"The key is a phenomenon called the Lidov-Kozai mechanism. The Lidov-Kozai mechanism is a gravitational three-body dance. Imagine the Sun, a small TNO-like object, and a massive perturbing body, in this case, our hypothetical Planet Nine. In this system, an unusual exchange of energy occurs. The orbit of the small object is not constant. Instead, it trades its parameters, so to speak. The object can give up some of its inclination relative to the system's plane. In return, it gains greater eccentricity, meaning its orbit becomes more egg-shaped, elongated. The opposite can also happen. This is a cyclic process. Planet Nine, orbiting on its distant path, slowly pumps, tilts, and stretches these orbits over millions of years. And it is this mechanism that explains why we see objects with such extreme orbits, perpendicular to the ecliptic, and even moving retrograde. Without a third massive player in this system, the math simply doesn't add up. "

They knew exactly how such an object should move against the background of stars over those 23 years.

"In 2003, Mike Brown's team discovered Sedna, a dwarf planet with an orbit so stretched and strange that it could not be explained by the presence of known planets. Then we found more objects and started to notice a pattern. Their orbits are combed in some way. Many of them are inclined at the same angle, and their perihelia, the points closest to the sun, cluster in one area. Some even orbit in the opposite direction to the rest of the solar system.

"If it's not a dumbbell, but a disk rotating axially, it won't be a source of gravitational waves, but an already distorted disk will be such a source. If it's a supernova and the supernova explodes very symmetrically, as they say, it won't be a source of gravitational waves, but supernovae most often explode in a way where there's a difference in the amount of matter going in different directions, due to magnetic fields, rotations, and so on. And at that moment, there's a pulsating star, because there's also acceleration, it pulsates and slows down. If it's a strictly symmetrical star, one that expands uniformly throughout its volume, it also won't be a source, but a star that has something called a quadrupole moment, where some parts go up and others contract, because that's usually how it looks, such a star will be a source.
