Welcome to the sixth in a series of short videos that we will be uploading that highlights the gaps in the Big Bang theory and the Standard Model of Cosmology. The Big Bang theory is presented by a lot of famous scientists like Professor Brian Cox and Neil deGrasse Tyson as an almost a factual account of the creation of our universe. The fact is though that the Big Bang theory has lots of gaps that scientists themselves have uncovered, and the theory really doesn't hold together particularly well. <br/><br/><br/>The idea behind these series of videos is to give viewers an insight into the gaps in the theory and allow viewers to make a more informed judgement on the creation of our universe and the purpose of our existence. <br/><br/><br/>This sixth video in the series discusses the Principle of Mediocrity, a notion that the Earth is not at all special and we human being are just a statistical fluke. But as scientists started to discover how precisely the universe is structured, they started to realise maybe things are not as they seemed.<br/><br/>If you haven’t done so already, please check out the first five videos in the series available on this channel.<br/><br/>For more information, please check out the book \

In 1998 graduate student Saul Perlmutter decided to do find out if our universe would slowly expand forever or whether at some stage it collapses and come to an end. What he discovered completely bamboozled scientists.And scientists had to come up with another name for something that completely mystified them: Dark Energy.<br/><br/><br/>In future videos we will delve into the mysteries of the fine tuning of the universe and many other aspects that are quite problematical for the Big Bang theory.

Kinematics, Two Dimension Motion, Projectile Motion #physics #yt #motion #projectilemotion #2dmotion <br/><br/><br/>In this lecture, I'll discuss Motion Under Gravity Two Dimension Motion (Projectile Motion) In Kinematics.<br/>Two-dimensional motion is motion that takes place in two different directions (or coordinates) at the same time. Two examples of two-dimensional motion are projectile and circular, where the relevant forces are gravitational and centripetal, respectively.<br/>Projectile motion is the motion of an object thrown (projected) into the air when, after the initial force that launches the object, air resistance is negligible and the only other force that object experiences is the force of gravity. The object is called a projectile, and its path is called its trajectory.<br/>Projectile motion is a form of motion experienced by an object or particle that is projected in a gravitational field, such as from Earth's surface, and moves along a curved path under the action of gravity only.<br/>In the universe, when an object is lifted or away from the ground, then a force is applied to the object in the downward direction. This force is known as the gravity force. When an object moves due to the application of the gravity force, its motion is known as a motion under gravity.<br/>The Time-of-Flight principle (ToF) is a method for measuring the distance between a sensor and an object, based on the time difference between the emission of a signal and its return to the sensor, after being reflected by an object.<br/>The range of a projectile is the horizontal distance the projectile travels from the time it is launched to the time it comes back down to the same height at which it is launched.<br/>This is the time of flight for a projectile both launched and impacting on a flat horizontal surface.<br/>The maximum height of a projectile is given by the formula H = u sin θ 2 2 g , where is the initial velocity, is the angle at which the object is thrown and is the acceleration due to gravity.<br/>The maximum height of a projectile above its launch position and it depends only on the vertical component of the initial velocity.<br/><br/>#projectile #projectile_motion #timeofflight #rangeinprojectile #equationoftrajectory #motionundergravity #groundtogroundprojectile #class11 #class11th #11th #11thclass #jeemain2024 #jeemain2025 #jeemains #jeemain #physics11 <br/><br/>kinematics, two dimension motion,two dimension motion class 11th,two dimension motion class 11, projectile motion, projectile motion class 11th, projectile motion class 11, projectile motion class11, motion under gravity class 11th, motion under gravity class 11, motion under gravity class, projectile motion class 11 ak sir, two dimension motion ak sir, two dimension motion jee mains, two dimension motion jee main, projectile motion jee mains, time of flight, projectile motion neet, jee mains, jee main, class 11th, class 11, physics, ak sir, aksir,
