Theory of Everything (ToE) is a hypothetical theory that completely explains and links together all physical aspects of the universe. Such a theory would merge the four known fundamental forces of the universe together. The Grand Unified Theory (GUT) successfully unites three of the four fundamental forces, namely the strong nuclear force, the weak nuclear force […]Read More Four leading candidates for ‘A Theory of Everything’
Our Universe, as we can perceive, has three spatial dimensions and one temporal dimension. Humans are three dimensional beings. Objects in 3D space have different lengths, different heights and different widths. Certain theories in physics suggest that our universe may have additional higher dimensions. Humans, being three dimensional organisms, cannot sense or perceive these dimensions. […]Read More What would our Universe look like from the fourth dimension?
Geminids are considered to be one of the most spectacular meteor showers of the year. These meteors are caused when streams of cosmic debris from the asteroid 3200 Phaethon enter Earth’s atmosphere. Geminids peak every year around December 13-14. One can expect to see more than 100 meteors per hour under optimal conditions. When to […]Read More How to Watch Geminids: The king of meteor showers
Absolute zero or zero kelvin is the minimum possible temperature that can be attained in the universe. At absolute zero, the volume of an ideal gas approaches zero. Temperature is the measure of the average heat in a substance. A substance at any temperature (other than absolute zero) consists of molecules that are in motion. […]Read More How do objects behave at absolute zero temperature?
Out of the total mass-energy content of the universe, regular matter- the matter that makes up stars, planets and people, adds up to less than 5%. The remaining 95% is made up of stuff that we can’t see or detect. Popularly known as dark matter and dark energy, they make up 26% and 69% of […]Read More Is there a fifth fundamental force in the universe?
Technology is advancing rapidly. According to Moore’s Law, the speed and memory capacity of computers doubles every 18 months. If computers continue to obey Moore’s Law, they will surpass human intelligence at some point in the next hundred years. Today, we have quantum computers that are 100 million times faster than a regular computer in […]Read More Are we living in a computer simulation?
The concept of gravity was introduced by Issac Newton in the year 1687 AD. Newton described gravity as the force of attraction between objects having mass. Albert Einstein drastically changed this view of gravity when he published his famous general theory of relativity in the year 1916. According to general relativity, gravity is not just […]Read More Why does gravity travel across dimensions?
