The Sun and Blackbody Radiation

March 18, 2023

The Sun’s temperature is not a constant and differs at the center and the surface. The corona is hotter than the surface. These temperatures and the light coming through are at diverse wavelengths and emit blackbody radiation. […]

Diffraction Gratings: Revolutionising Astronomical Studies

March 18, 2023

Diffraction gratings have enabled astronomers to study light spectrum with greater precision. Previously, a prism was used in its place. Though effective, a prism worked slightly differently whenever used. Therefore, no consistent, reproducible results could be achieved. […]

Fusion: The Sun’s Power Source

March 15, 2023

The source of our Sun’s energy is fusion. It is a process where two protons fuse together into what is called a deuterium nucleus, which is a proton and a neutron. And yet, it isn’t only one but fusion of all of the elements, up to iron, can occur. […]

Can We Make a Subatomic Black Hole?

March 8, 2023

The fears regarding subatomic black holes are not founded. Physicists like Stephen Hawking believe that even if subatomic black holes are real, they evaporate away before becoming dangerous. […]

Are Particle Accelerators Really Dangerous?

March 8, 2023

Though they are certain worries vis-à-vis the particle accelerators, they are not backed by science. One of the concerns is that large accelerators might make subatomic particles, called ‘strangelets’. […]

The Big Bang Theory: Surviving Critics

January 24, 2023

The age of the Methuselah star is estimated to be 14.46 ± 0.8 billion years, making it older than the estimated age of the universe itself. This casts doubts regarding the validity of the origin of the universe, vis-à-vis the big bang theory. […]

CMB and the Geometry of the Universe

January 23, 2023

According to general relativity, matter and energy in space distort both space and time. When it comes to the geometry of the universe, its shape is determined by the critical amount of mass it contains. […]
