The biggest Mystery of Dark Energy and Dark Matter

Dark matter :


Dark matter is a mystery material that accounts for approximately 25% of the cosmos. It is unseen, yet its gravitational impacts on visible matter tell us it exists. Galaxies, for example, rotate more faster than they should if they were simply formed of stars and gas. This implies that they are held together by a large amount of invisible substance.

There are numerous hypotheses as to what dark matter is formed of. It could be composed of weakly interacting massive particles (WIMPs). These particles would interact with one another and with gravity, but not with light or other types of electromagnetic radiation. Another hypothesis is that dark matter is composed of axions, which are hypothetical particles hypothesized to overcome a difficulty in particle physics.


Dark energy:


Dark energy is far stranger than dark matter. It is assumed to be responsible for the universe's accelerated expansion. However, we have no idea what it is or why it is hastening the expansion.

One idea is that dark energy is a type of energy that is dispersed uniformly throughout the universe. This energy is supposed to be accelerating the expansion of the universe. Another idea is that dark energy is an inherent property of space. This characteristic would accelerate the expansion of space.


A vast range of data, including galaxies' rotation curves, gravitational lensing of light, and the cosmic microwave background, suggest the presence of dark matter and dark energy. However, we still don't know what they're constructed of or how they function. These are some of physics' biggest mysteries, and they could have a huge impact on our knowledge of the cosmos.


In addition to the information provided above, consider the following facts concerning dark matter and dark energy:

Dark matter and dark energy are assumed to have existed since the very beginning of the universe, and dark matter is thought to be necessary for the development of galaxies and galaxy clusters.

Dark energy is assumed to be responsible for the universe's accelerated expansion. The reality of dark matter and dark energy is still debated, however there is mounting evidence to support their presence.

We may ultimately be able to answer these questions as we discover more about the universe. But, for the time being, dark matter and dark energy remain some of physics' greatest mysteries.

Kilobots: The Next Generation of Robots

Kilobots: The Swarm Robots That Could Chang e the World • Swarm robotics is a fast expanding topic of study that investigates the use of huge groups of robots to execute activities that would be difficult or impossible for a single robot to perform.  •The Kilobot, a tiny robot roughly the size of a quarter, is one of the most promising platforms for swarm robotics. • Kilobots are extremely simple machines. They have two vibrating motors to move about, an infrared sensor to interact with one another, and a light to signal to other robots. • Their simplicity, though, is also their strength. Kilobots can be utilized in vast numbers because they are inexpensive and simple to construct, giving them the ability to attack. • Self-assembly is one of the most astounding abilities of Kilobots. This implies they may be programmed to form various forms and patterns without the need for human involvement. • They can, for example, be programmed to create a square, a circle, or even a human face. • K

What's up with those alien bodies? Presented by Mexican Congress.

Image
•  The presentation of suspected alien bodies to the Mexican Congress has stirred considerable curiosity and debate. • Jaime Maussan, a Mexican writer and UFO enthusiast, originally revealed the remnants, which are little, humanoid-shaped animals with elongated skulls and three fingers on each hand, in 2017.  • Although Maussan maintains that the bodies were discovered in Peru, their origin and authenticity have been called into question by specialists. • Maussan and other researchers presented the bodies to the Mexican Congress again in November 2023, this time with fresh evidence that they think proved their legitimacy. • Photographs, X-rays, and DNA analysis are among the evidence. However, the scientific community is still skeptical. Some scientists have noted that the bodies resemble recognized animal remains, while others have questioned the DNA analysis's veracity. • The public's reaction to the exhibition of the claimed alien bodies has been varied. Some people believ

Chandrayaan 3 : one step closer to the Moon.

Image
• On July 14, 2023, Chandrayaan 3 was successfully launched from the Satish Dhawan Space Centre in Sriharikota, India. • On August 5, 2023, the spacecraft entered lunar orbit; on August 23, 2023, the lander soft-landed on the lunar surface at Singhasan, near the lunar south pole. The lander is carrying the Pragyan rover, which will spend up to 14 days exploring the lunar surface. The Chandrayaan 3 mission is scheduled to last for one year. • The successful launch and landing of Chandrayaan 3 is a significant achievement for India's space program. This mission will assist India in becoming a leader in lunar exploration. Here are some of Chandrayaan 3's scientific goals: • Look for water molecules on the lunar surface;  Research the geology and composition of the moon. • Conduct research on the lunar atmosphere and dust environment. • Gather lunar rock and soil samples. • The data obtained by Chandrayaan 3 will aid scientists in their understanding of the Moon's creation and
