Two optical illusions

Kimmo Huosionmaa

The illusion can be caused by the line of two objects. In this picture, the cloud, what is behind houses seems like smoke, what is rising from burning things. That picture is picture one (Picture I) on the homepage. This kind of illusions causes many kinds of problems in the fire- and other departments of the cities. Optical illusions are fascinating, and they are claimed to cause even death of the travelers. There is a link to the page, where those pictures have been uploaded.

The classical thing is the phenomenon, called fata morgana, what means the illusion, where the rising air causes the effect of the water in very dry places. And this phenomenon can make a traveler drink too much water, and then the filling of those bottles is not available, but this kind of stories might sometimes from the people illusion.

The fata morgana can see even over the dry and hot streets if the person looks it in the direct angle. If the angle is right, the person would see things like water, and that explains, why children see this phenomenon more often than an adult. But when we are seeing optical illusions, there is another picture in this page (Picture II), and that is about the bubble inside the cloud. This kind of weather phenomenon can cause the alarm of UFO:s. But the thing is actually a bubble of the empty area inside the cloud, and there is no steam inside this bubble. Or the other explanation would be, that there is the darker area in the cloud.

The hydrogen-burning supernovas are interesting models.

"Researchers discovered a significant magnesium anomaly in a meteorite’s dust particle, challenging current astrophysical models and suggesting new insights into hydrogen-burning supernovas. (Artist’s concept.)Credit: SciTechDaily.com" (ScitechDaily, Rare Dust Particle From Ancient Extraterrestrial Meteorite Challenges Astrophysical Models) If the star is too heavy when its fusion reaction starts, it can detonate just at that moment, when its fusion starts. If the collapsing nebula is heavy enough, it can form a black hole straight from the nebula. But if the nebula's gravity is too heavy to form the blue giant or too small it can collapse straight into a black hole . If the forming star is a little bit larger than the blue supergiants. It can explode immediately when the fusion starts. The theory of hydrogen-burning supernovas consists model of the giant stars that explode immediately after their fusion starts. When the...

The ancient galaxy mirrors the Milky Way.

"This image shows the galaxy REBELS-25 as seen by the Atacama Large Millimeter/submillimeter Array (ALMA), overlaid on an infrared image of other stars and galaxies. The infrared image was taken by ESO’s Visible and Infrared Survey Telescope for Astronomy (VISTA). In a recent study, researchers found evidence that REBELS-25 is a strongly rotating disc galaxy existing only 700 million years after the Big Bang. This makes it the most distant and earliest known Milky Way-like galaxy found to date. Credit: ALMA (ESO/NAOJ/NRAO)/L. Rowland et al./ESO/J. Dunlop et al. Ack.: CASU, CALET" (ScitechDaily, Astronomers Baffled by Ancient Galaxy That Mirrors Modern Milky Way) Researchers found the youngest Milky Way-type galaxy. The distance to the galaxy is enormous. And the light that comes from that galaxy named REBELS-25 comes from the Universe that is only 700 million years old. The distance to that galaxy is enormous about 236 billion light years. And that means it's a very dista...

Transcendence, or the ability to transcendent thinking may grow in teen's brains.

"New research has discovered that transcendent thinking, which involves analyzing the broader implications of situations, can foster brain growth in adolescents. This form of thinking enhances brain network coordination, impacting developmental milestones and future life satisfaction. The study emphasizes the need for education that encourages deep, reflective thought, underscoring the critical role of adolescents in their own brain development". (ScitechDaily, Scientists Discover That “Transcendent” Thinking May Grow Teens’ Brains) "Scientists at USC Rossier School of Education’s Center for Affective Neuroscience, Development, Learning and Education (CANDLE) have discovered that adolescents who grapple with the bigger meaning of social situations experience greater brain growth, which predicts stronger identity development and life satisfaction years later". (ScitechDaily, Scientists Discover That “Transcendent” Thinking May Grow Teens’ Brains) The transcendenc...
