Dark Matter The Matter We CanT See

The article discusses the ancient Greek’s theory of the universe, which believed that the universe was made up of four elements: earth, air, fire, and water. However, this theory was proven incorrect and was replaced by Leucippus’s atom theory, which proposed that everything is made up of tiny, indivisible bits of stuff called atoms. The article also explores the concept of the dark universe, consisting of dark matter and dark energy, which make up 95% of the universe. The composition of the universe is estimated to be 68% dark energy, 27% dark matter, and only 5% visible matter. The article concludes by discussing theories about the universe’s diversity and the potential for further exploration and understanding.

How Tsunamis Work

This article explains the phenomenon of tsunamis and their destructive impact. It discusses how tsunamis are formed by underwater energy, often resulting from earthquakes, and how they can reach heights of up to 100 feet. The article also highlights the challenges of protecting against tsunamis and emphasizes the importance of early detection and alert systems.

Where Did Earth’s Water Come From

The article explains that Earth’s unique water composition, with its 70% liquid water surface, is peculiar given what we know about the formation of our solar system. The early inner solar system was too hot for water to exist, so scientists believe that Earth’s water must have come from meteoroids or comets that originated in the outer solar system where frozen water could survive. The most likely source for Earth’s water is carbonaceous chondrites, a type of meteorite that contains water and has similar levels of heavy hydrogen to Earth’s water.

The myth of the boiling frog

The article presents the metaphor of the frog parable to illustrate human behavior towards climate change. It emphasizes the need for immediate action to reduce greenhouse gas emissions and prevent further global warming, highlighting the role of fossil fuels in climate change and the potential consequences of rising temperatures. The article suggests that while transitioning to clean energy sources will take time, efforts to remove carbon from the atmosphere can help mitigate the damage caused by climate change.

Natures fortress How cacti keep water in and predators out

Cacti have evolved various adaptations to survive in harsh desert climates. Their spines serve multiple functions, including reducing water loss, shading the plant, and acting as an insulating layer. Cacti also have thick skin and specialized root systems that allow them to store water and quickly take up available water after rainfall. These adaptations enable cacti to thrive in a range of environments, from the driest desert to the tropical rainforest.

What If You Stopped Drinking Water

Water is essential for the survival of all living organisms, with the human body being made up of 65% water. The body loses around 2.5 liters of water every day and it is crucial to replenish these fluids. More than 783 million people on earth do not have access to clean water, and scientists are working on solutions such as removing salt from ocean water and creating innovative water filtration systems, while water charities have fantastic initiatives that individuals can contribute to.

Can You Freeze Yourself and Come Back to Life?

James Bedford was the first person to be cryogenically frozen in 1967 in order to cheat death. The process of cryopreservation, as studied by cryobiology, is difficult, as damage can occur when trying to lower the temperature. Despite research into cold-tolerant animals and vitrification techniques, cryonics cannot currently preserve a human body indefinitely and the dream of cryonics is still on ice.
