Fifth Force of Nature discovered
GS Paper - 3 (Science and Technology)
Scientists at the Fermilab situated near Chicago have claimed to have discovered a new force or the fifth force of nature. If proven, this may be the beginning of a new revolution in physics and could prove to be the most significant discovery after Albert Einstein’s Theory of Relativity.
What is the Fifth Force of Nature?
The entire universe is governed by four forces- gravity, electromagnetism, the weak force, and the strong force. Now, scientists claim to have found a new force or the fifth force.
How was the Fifth Force of Nature discovered?
In an experiment called ‘g-2’ or ‘g minus 2’ at Fermilab, the researchers accelerated sub-atomic particles called muons through a 50-meter diameter ring and circulated these particles 1,000 times at near light speed and found that these particles did not behave the way they should.
Their behaviour cannot be explained by the current theory called the Standard Model because these particles were under the influence of a new force.
Muons are electron-like sub-atomic particles that orbit atoms, but they are 200 times bigger.
In the experiment, they were made to wobble using superconducting magnets. But they wobbled faster than predicted by the Standard Model. This might be caused by a new force or the fifth force.
The scientists at Europe’s Large Hadron Collider are also trying to find flaws in the Standard Model.
Dr. Mitesh Patel from Imperial College London is one of those thousands of scientists who are working at the LHC, trying to find experimental results showing the flaws in the Standard Model.
The measuring behaviour that does not comply with the Standard Model is the holy grail of particle physics and it may trigger a revolution that may begin a new understanding of physics.

JWST discovered Earendel
GS Paper - 3 (Space Technology)
Astronomers have embarked on an extraordinary journey, utilizing the powerful gaze of the James Webb Space Telescope (JWST), to measure the most distant star ever observed - Earendel. This celestial entity came into the scientific spotlight after its discovery by the Hubble Space Telescope in the previous year.
Earendel and history of the universe
The awe-inspiring expansion of the universe since the Big Bang has propelled Earendel's residence to a colossal 28 billion light-years from Earth.
This revelation underscores the dynamic and evolving nature of the cosmos, where space itself unfurls over immense timescales.
Earendel's presence in the distant reaches of the universe was initially pinpointed through the phenomenon of gravitational lensing, a phenomenon where the gravitational pull of a massive foreground object acts like a lens, bending and amplifying the light of a more distant celestial body. This allowed Hubble to identify Earendel's distant glow.
What is Earendel?
Earendel is a distant star that holds the distinction of being the most distant star ever detected.
It was first discovered by the Hubble Space Telescope and has recently been studied further using the James Webb Space Telescope.
Earendel's light has taken approximately 12.9 billion years to reach Earth, meaning that it was shining not long after the universe's creation following the Big Bang.
This star is of significant interest due to its extreme distance and the insights it can provide about the early universe.
JWST's exploration of Earendel
The James Webb Space Telescope, with its unique vantage point and ability to observe in infrared light, built on Hubble's observations.
Employing a similar strategy of gravitational lensing, JWST used the gravitational influence of a cluster named WHL0137-08 to further explore Earendel's mysteries.
The telescope's Near-Infrared Camera (NIRCam) provided captivating insights, revealing Earendel to be a massive B-type star, boasting a temperature more than twice that of our sun and shining with a luminosity a million times greater.
What is JWST?
The James Webb Space Telescope (JWST) is a powerful astronomical observatory developed by NASA in collaboration with the European Space Agency (ESA) and the Canadian Space Agency (CSA).
It is designed to be the successor to the Hubble Space Telescope and is set to provide unprecedented views of the universe in infrared light.
