Black Holes, Gravity and Time (Part - 3)

 

 

                   Down The Rabbit Hole: What's Inside A Black Hole? | by Amelia Settembre | Medium

 

 

              If a black hole has mass to almost that of infinity, then what about its curvature in space-time? The gravity of Black Hole is so intense that it either destroys the space time or it bends the space time without any end (as shown in the picture above). 

              Gravity, as we all are taught, is a type of force. Is it actually true? Well, a theory proposed by Ahmed Farag Ali and Saurya Das (which is said to unify Albert Einstein's General Relativity and The Quantum Theory), said that gravitational force has its own force carriers, which have no mass and charge but carry gravitational force just like photons (the basic particle of light) called Gravitons. To the day, no one's really found a graviton.

              Gravity, according to Newtonian physics is a force of attraction between two bodies with same or variable mass. Gravity is directly proportional to the product of the masses of the two objects or is inversely proportional to the square of the distance between them. Gravity is the force that gives us weight. It is the weakest of the 4 forces in nature. It can bend light and time as well.

              Time, we always hear time is running out. Is it really running out? According to me(not really), time was created by watch making companies to sell their watches. Jokes apart, time is an interval between two events or whatsoever. Time according to Einstein, is the 4th dimension of the universe. It is so because, it tells when will we be found on the given X,Y,Z coordinates (which are the other 3 dimensions of the universe). Dimensions are said so because, it tells us when and where we can find something. 

              Einstein in his special relativity also included that time runs according to one's perspective and not on whole. Gravity as we all know bends warps, slows time, that is because gravity can change dimensions of anything. When the gravity of an object increases, time slows and vice versa. For example, your friend is on earth and your 2nd friend is on Jupiter, if a you observe their watches ticking side by side, you'll observe that the watch of your friend on Jupiter ticks slowly compared to the other one. The slowing down of time in case of your second friend for you is called Time Dilation. This means, you'll tell your 2nd friend that he experienced Time Dilation but for him time was the same and his watch was ticking in normal speed.

              So, here your perspective says that he experienced Time Dilation but for him time was the same. Hence, Time needs one's perspective. And also, time dilation occurs when you travel at various speeds. If you travel at the speed of light, Time naturally stops for you i.e, you don't age any further.

Antimatter

Image
                              Matter and Antimatter were both formed in equal amounts when there was The Big Bang. Matter consists of molecules which have atoms and atoms have subatomic particles (electron, proton and neutron). Antimatter as the name suggests it is something which is against the matter. Antimatter also has molecules in which there are atoms. But, here comes the reason why they really are called antimatter . Unlike matter, antimatter has positrons (positively charged particles) instead of electrons, anti-protons instead of protons, anti-neutrons instead of neutrons. All the particles of antimatter have equal and opposite charge and mass but the difference comes in its quantum numbers.               Antimatter was found in 1964 by James Cronin and Val Fitch. This was the basic info on antimatter. Let's come to the interesting part - What if antimatter were to collided with matter? When antimatter collides with matter it forms pure energy, neutrons and Gamma radiatio

The Process of Respiration (Part - 2)

Image
              The lungs are the site for exchange of gases. Lungs are present in the chest cavity or thorax cavity.The lungs are protected by brist bone/chest bone/sternum from the front, rib cage from sides and back bone or vertebral column from back. When we breathe in our lungs expand, moving ribs outward. When we breathe out our lungs contract, moving ribs inward.               At the bottom of the lungs a structure called diaphragm is present, which helps the lungs to expand and contract properly. Not only that, they also stop lungs from damaging the stomach. When we breathe in the diaphragm moves downward and when we breathe out they move inward. The diaphragm is also called the floor of chest cavity as it is the bottom most structure of the chest cavity.               The oxygenated blood from the heart is supplied to almost all the cells by blood vessels. The end of the blood vessel is a blood cappillary, which connects to the cell. When the blood reache

The Dark Matter

Image
                   Matter, we have known this word for long. "Matter is anything that occupies space and has mass". Everything we see, we touch, we feel is in fact matter. "Energy is the ability to do work". We knew this until 1933 when Dark Matter was discovered and 1998 when Dark Energy was discovered.                                Dark matter looks like this:                                Yes, this is indeed the Dark Matter. The Dark Matter is a kind of matter that cannot radiate, absorb or reflect light. Then a question arises, then how come do we know that Dark Matter really existed? This was because as it has its own effects on things that are visible. Dark Matter is a substance which enhances the gravitational force of visible matter. It is the only reason and explanation of rotation and revolution of planets, stars, galaxies. Dark Matter is non-baryonic (meaning they do not contain visible matter) instead they have subatomic particles which are yet to be d
