Dark Matter and Dark Energy (All Articles)

What caused the formation of galaxies?

Dark matter, making up 85% of the universe's mass, acted as the "glue" pulling galaxies together and forming the cosmic web. Without it, only 10% of galaxies would exist. How did dark matter shape the universe's structure and influence galaxy formation? Read the full article to uncover the secrets.

What is the role of the unseen matter in the universe?

Dark matter acts as the invisible glue holding galaxies together and plays a crucial role in forming the universe's large-scale structures. It outweighs normal matter by a ratio of 5:1, significantly influencing the gravitational forces that shape galaxies and cosmic structures. Understanding dark matter is essential for uncovering the fundamental forces that govern the cosmos. How does dark matter impact the formation and stability of galaxies?

What is it called when gravity bends light?

Gravitational lensing, a phenomenon predicted by Einstein, occurs when massive objects bend light from distant galaxies, making them appear distorted or magnified. This effect reveals hidden dark matter and allows us to study far-off galaxies and cosmic redshift. Researchers use telescopes and simulations to analyze this bending of light, uncovering details about the universe's expansion and dark matter.

What is another name for normal matter?

Baryonic matter is the visible matter in the universe, composed of baryons like protons and neutrons, and makes up about 4.6% of the universe's total energy density. This matter exists primarily in stars, galaxies, and interstellar gas, playing a crucial role in cosmic structures and galaxy formation. Interestingly, only about 50% of baryonic matter is visible, with the rest existing as diffuse gas. How does baryonic matter influence star formation in galaxies? Click the button below!
