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.

Parachute deployment tests for Gaganyaan
GS Paper - 3 (Space Technology)
ISRO has successfully conducted a series of tests on drogue parachutes, which would play a pivotal role in stabilising the crew module and reducing its velocity to a safe level during re-entry in the planned Gaganyaan human space flight mission.
More about the Mission
The Gaganyaan mission hopes to safely transport astronauts to Space and back. Drogue parachutes are deployed to decrease speed and stabilise rapidly moving objects.
ISRO's Thiruvananthapuram-based Vikram Sarabhai Space Centre (VSSC) successfully conducted a series of Drogue Parachute Deployment Tests at the Rail Track Rocket Sled (RTRS) facility of the Terminal Ballistics Research Laboratory in Chandigarh during 8-10 August.
The tests were conducted in collaboration with Aerial Delivery Research and Development Establishment (ADRDE)/DRDO.
The drogue parachutes, packed within pyro-based devices known as mortars, are cleverly designed to eject the parachutes into the air upon command.
These conical ribbon-type parachutes, boasting a diameter of 5.8 metres, employ a single-stage reefing mechanism, ingeniously minimising canopy area and mitigating opening shock, ensuring a smooth and controlled descent.
During the three comprehensive tests conducted at the RTRS facility, a range of real-world scenarios were simulated to rigorously evaluate the performance and reliability of the drogue parachutes.
The first test simulated the maximum reefed load, marking a groundbreaking introduction of reefing in a mortar-deployed parachute within India.
The second test emulated the maximum dis-reefed load, while the third test showcased the deployment of the drogue parachute under conditions mirroring the maximum angle of attack experienced by the crew module during its mission.
These successful RTRS tests serve as a critical qualification milestone for the drogue parachutes, confirming their readiness for integration into the upcoming Test Vehicle-D1 mission.
Notably, earlier this year, theRTRS tests of Pilot and Apex cover separation parachutes were also conducted, further accentuating the progress of the Gaganyaan mission's parachute system development.
Theintricate parachute sequence for the Gaganyaan crew module's deceleration system encompasses a total of 10 parachutes.
