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. […]

Light and Relativity: Is the Speed of Light Constant?

December 18, 2022

Modern measurement allows us to inarguably prove that light does travel at one speed for all observers. It can be done using a particle accelerator to shoot an electron at nearly the speed of light. It is completed by simply measuring how long it takes for electron to go that distance. […]

Killing Aether: The Michelson-Morley Experiment

December 18, 2022

Michelson-Morley experiment set out to observe a difference in the speed light corresponding to the changing orientation. Surprisingly, the result showed absence of any difference in the speed of light along with the absence of aether as a medium through which light was thought to have been conducted. […]

Transmission of Light and Electromagnetic Waves

December 18, 2022

It was thought in ancient Greek times that it was aether that existed in the universe and conducted light. And yet, it didn’t completely explain when it came to the question of whether it was aether that was moving or was it the earth which was moving in aether. […]

Measuring the Speed of Light

December 17, 2022

Danish astronomer Ole Roemer was the first one who attempted to measure the speed of light. He relied on the precise measurements of the eclipse of Jupiter’s moon, Io. He timed it exactly to calculate the time it took to travel from one side of the Earth’s orbit to the other, giving him the speed of light. […]
