5 Mysteries of the Universe That Science Can’t Explain

Throughout human history, science has astounded global communities by providing astonishing answers about many of the most curious phenomena found on Earth – or beyond. Today, even with virtually unrestricted access to valuable knowledge, many questions remain unanswered, as researchers dedicate their projects to understanding how some of these mysteries are elucidated and ultimately resolved.

see below universe puzzles Which remains unfinished due to limited technology, human failure, and difficulties in accessing unexplored areas.

1. What is the universe made of?

Although studies of the most remote regions of the universe have advanced significantly in recent years, especially in the departments of black holes and gravitational phenomena, scientists have failed to get answers about what happens in about 95% of the accessible universe.

Since most of it is untouchable and invisible, even with advanced long-range technologies, dark matter – the so-called veil that covers most of the universe – remains unknown to experts, and its origin and formation is one of the greatest mysteries of astronomy.

2. What is in the twilight zone of the ocean?

Known as the twilight zone in the ocean, which lies between 200 and 1,000 meters below the surface, the Mediterranean is a place where exoticism reigns. Amid the darkness caused by the complete absence of sunlight, creatures with small eyes and large teeth.

In addition, the site is brimming with bioluminescent organisms that navigate the undiscovered waters and is of interest to researchers who believe there is a gradual increase in biomass in the area—where there are more fish than the rest of the entire ocean combined—and broadly supporting climate regulation.

3. What made Venus uninhabitable?

900°C At the surface, the atmosphere is made almost entirely of carbon dioxide, clouds of highly corrosive sulfuric acid, eruptions with powerful lava flows, and pressures 92 times that of Earth: How did Venus get to this point?

It is considered the “brother” of the Earth because it was formed at the same time – its age is estimated at 300-600 million years – and with the same materials, the second closest planet to the Sun became a real inferno, and the reasons for this phenomenon follow with few answers. Today, the strongest hypotheses suggest that volcanic events and proximity to the Sun are most responsible for the critical rise in body temperatures.

4. Or what causes Alzheimer’s disease?

Since 1910, when the term Alzheimer’s was originally defined, advances in drugs and clinical technology have contributed to studies of the disease, but no effective treatment has been found and the condition remains incurable. Currently, there is also no scientific consensus on the main causes of Alzheimer’s disease.

The most popular theory is that amyloid proteins, the proteins that make up plaque in the brain, trigger dementia after the substance builds up. But why don’t drugs that fight these proteins work? Nobody knows how to say.

5. Why does a person have an anus?

Before the anus existed, ancestors ate and excreted from the same opening, making it impossible for animals to develop an efficient life system to take on new forms.

Superficial analyzes indicate that the last part of the digestive system arose about 550 million years ago, but little is known about the first animal to evolve the structure and its evolutionary model in species over time.
