Everything in the universe is made up of particles; some have mass and some don't. But what causes some particles to have mass while others do not? The Higgs Boson, or God particle, is responsible for the mass of matter.
πΏπππΎπππππ:
The Higgs boson was theorized in 1960 by Peter Higgs and five other scientists as a particle responsible for the mass of matter. While it was not discovered until 2012, the Higgs boson was first experienced practically at the Large Hadron Collider (LHC).
It is the largest particle accelerator in the world, consisting of a 27km-long ring. The LHC is basically used to collide hadrons (particles made up of quarks). It accelerates particles at very high speeds using powerful magnets.
On 4th July 2012 scientists fired protons into the collider traveling in opposite directions. Magnets accelerated the protons to 99.9999991% of the speed of light. Protons are made up of three quarks. Quarks inside protons collide with enough energy to create the suspected Higgs.

Particles gain mass by interacting with the Higgs field; they do not have mass of their own. The stronger a particle interacts with the Higgs field, the more mass it gains. For example, photons do not interact with this field and therefore have no mass.
The Higgs field is like a sea through which particles move. When particles interact with this field they experience resistance, slowing them down and giving them energy, which behaves as mass, according to Einstein's equation E = mcΒ².
The Higgs Boson was discovered by Peter Higgs. It is a boson, means it obeys Bose-Einstein Statistics, where two particles can occupy the same quantum state, unlike fermions, which obey Fermi-Dirac Statistics and the Pauli exclusion principle.
The nickname βGod particleβ originated from the title of the book βThe God Particle: If the Universe is the Answer, What is the Question?β by physicist Leon Lederman. The Higgs gained this nickname because it was believed to be the last piece of the standard model of particles.
ππππππππππ:
The Higgs particle gives mass to other particles, but surprisingly, it also has its own mass because it interacts with its own field. With a mass 130 times that of the proton, the Higgs boson is the second-heaviest particle known today after the top quark.
The Higgs Boson is a highly unstable particle with a lifetime of 10-Β²Β² seconds, meaning that the particle cannot be found in nature. It can decay into various combinations of particles. The Higgs boson is a chargeless particle and is its own antiparticle.

Seismic waves are energy waves generated by earthquakes or other geological processes that travel through the Earth's layers. They can be categorized into two types: Body waves and Surface waves based on their mode of propagation.
1) π½ππΏπ ππΌπππ:
Type of seismic waves that travel through the Earth's interior layers. They are faster than surface waves and are the first to be detected by seismographs after an earthquake occurs. Body waves can be further divided into two types: P waves and S waves.
P waves, or Primary Waves, are the fastest of all seismic waves and the first wave to arrive. P waves are compressional waves, meaning they propagate like sound waves through compression and dilation in the medium.
A Neutron Star is the smallest and densest star ever known, composed mainly of neutrons. Its size ranges from 10 km to 20 km. It was theorized in 1934, just two years after the discovery of the neutron particle, and discovered in 1967.
πππππΌππππ:
A neutron star forms when a massive star with a mass of 8 to 20 solar masses runs out of fuel. When a star exhaust its fuel and can no longer generate energy through nuclear fusion, its core fails to produce enough pressure to counteract gravitational forces.
The star begins to contract under its own gravity. For massive stars, it is intense enough to fuse electrons and protons together, resulting in the formation of neutrons. This process leaves behind a dense star composed almost entirely of neutrons, which we call a "Neutron Star."
General Relativity is Einstein's theory of gravitation published in 1915, ten years after Special Relativity. It is essentially a theory about space, time and gravity, it also deals with phenomena in intense gravitational fields.
πππΌπΎπππππ:
Albert Einstein concluded that space and time are not two different things but one. Space includes three dimensions: length, breadth, and height. The universe is not three-dimensional; there's a fourth dimension too, which is time.
A dimension is like a direction you can move in. Just as we can move in space (i.e., back and forth, left and right, up and down), we can move in time too. Surprisingly, we can move into the future but can't go back to the past.
ICUBE-Q is a Pakistani CubeSat launched on May 3, 2024 by China. A CubeSat is a type of satellite with a cubic shape and a size of 10 cm or more. The Q here stands for Qamar, which is an Arabic word for Moon.
The Chang'e 6 mission is a Chinese lunar mission that will carry ICUBE-Q with it. It's the sixth lunar mission of China aimed at exploring the moon. Chang'e is the name of the Chinese goddess of the moon. The Chang'e program consist of four phases:
πππππ πππππ:
The first phase is to reach lunar orbit to explore the visible area of the moon and create a 3D map of the lunar surface. This was achieved by Chang'e 1 in 2007 and Chang'e 2 in 2010.
Everything has a beginning and an end. The Big Bang was the beginning of the universe, but how will it end? Based on long-term research and evidence collected by various sources, scientists have proposed several theories.
The universe came into existence from a point called singularity, as it started to expand and this expansion is still continue. In the beginning of the 20th century, Edwin Hubble found the first evidence of an expanding universe, leading to the acceptance of the Big Bang theory.
But why does it expand? It should contract due to gravitational force. The reason is unknown; scientists call it dark energy, which expands the universe. Dark energy plays an important role in understanding the fate of the universe.
The Big Bang theory is the widely accepted theory, explains the beginning of the universe. It was proposed in 1931, and the term 'Big Bang' was coined in 1949. It seems like there was an explosion from name, but actually, the Big Bang is a misnomer.
πππππππΌππππ:
The Big Bang theory suggest that the universe began from Singularity, point of infinite density and temp. Then a rapid expansion started and the temperature started to fall. This expansion is still continuing and everything in the universe is moving apart
According to Big Bang theory time began with the Big Bang. And before the Big Bang there was no time mean there was no before. While the string theory suggest the possibility of the existence of time even before Big Bang so it's still a mystery
