TIME is also a DIMENSION , JUST LIKE SPACE !

- Einstein’s theory of special relativity treats time as a dimension just like space. Is time really a dimension ? what time even is ?
In this video we will talk about how Einstein’s theory of special relativity almost demands for time to be a dimension . We will also try to understand how space and time are connected , and how time can be understood as a dimension just like space.
Why time only moves forward and its connection to entropy and the second law of thermodynamics ?
We will also discuss about the fact that everything in the universe travels at one fixed speed through space time that of light , and how moving through space slows down our velocity through time . how do we travel through time at the speed of light when we are at rest. Why time stops at the speed of light . what would happen to time after the heat death of the universe , will time reverse its direction . Can time stop flowing ?
Also in general relativity gravity is not only the curvature of space but is also the curvature of time.

well done for crediting minkowski for four velocity/vector spacetime, and minkowskis spacetime talk and papers are still the default explanation of length contraction. in fact there would be no time dilation or length contraction if four dimensional spacetime was not true. i.e. if there were just the three dimensional euclidean dimensions these relativistic effects would not be possible. and the spacetime curviture has to have an addtional dimension to curve into on top of the three familiar spatial dimensions. minkowskis work on special relativity was far more revolutionary than people realise today. spacetime interval, spacetime diagrams, worldlines, four dimensional non euclidean geometry, It was all minkowski . he understood that not only did everyone effectively have their own clock/time in their own reference frame, so there is not ONE time, but also there is not ONE space either, but in four dimension spacetime there are infinite spaces, and that is why each person measures time and lengths using their own ''clock' and ''ruler, which means there is not one now, but many nows as each person because of the relativity of simultaneity is measuring different three dimensional crosssections of the more fundamental four dimensional spacetime. minkowski discovered the fundamental ''spacetime interval'' which unlike the many times and spaces, is truly fundamental, agreed upon by all observers. That is with the lorentz transformations-as person is physical rotated more in the spatial coodinates or in the time coodinate, with the speed of light which were termed timelioke and spacelike. human beings along are moving almost exclusively in the timelike direction-through time, and hardly anything through space. using boosts an object would become more rotated in spacelike coordinates and move less through time, just like the twins paradox though experiment. and you get a huge amount of time dilation/rotation in spacelike direction with high velocities. the returning twin has been in a different reference frame than the twin who stayed on earth. the travelling twin has hardly aged, the twin on earth may be say fifty years older. there are examples where a human lifespan two way trip by an astronaut at high velicity can have them return to earth where on earth it is ten thousand or more years in the future, and obviously everyone they ever knew is long dead. which is an ultimate demonstration of the true conceptual power of the lorentz transformations, the minkowki spacetime framework, einstein's discovery of coodinate and local time, and lorentz discovery of length contraction. minkowski tragiicaly died very soon after his spacetime discovery.
Hi, it's me again. Loving the content. Time is a measure for the span of the duration of a phenomena.
Velocity creates time dilation. Gravity is velocity generated from geometry.
Very good video, I through it was better than Sabine Hossenfelder’s
I've been writting a physics blog with good success recently, I really love to explain the amazing insights of physics to Laymen or anyone not an expert. I only have an honours degree in quantum physics and applied mathematics but it gets me by lol. Would be really great to teamwork with someone with these skils and great knowlege like yourself!
The light photon forms the movement of charge with potential energy continuously transforming into the kinetic energy of matter in the form of electrons.
Within each reference frame, the absorption of light will always come before and emission forming an Arrow of time with an uncertain future that is relative to the energy and momentum of our actions. I believe we need to go back to mathematics that represents the geometry of three-dimensional space with one variable in the form of time. Spherical geometry can give us this, because an interior of a sphere is naturally three-dimensional and the geometrical process 'time' can unfold relative to the spherical surface. The two dimensional surface can form a boundary condition for the movement of positive and negative charge.
Very nice explanation, your accent was hard to understand at times, but I enjoyed your explanation 😀
Isnt me walking backwards still just accelerating forward from position? We never go backward or reverse.
Can you tell me how you learn all these information?
There's not one particular source. I learn through various ways , such as RUclips , internet , books etc. Hope this helps. Thanks.
