What is Polchinsky Paradox?
Who doesn't love a good old-fashioned time paradox? Theoretical physicist Joseph Polchinski posed a puzzle to another physicists in a letter: If you throw a billiard ball into one end, at the right Speed and angle, such that it comes out of the other end. The time …
The Holographic Universe
Along with other Conservation laws in physics, "Conservation of Information" is a fundamental law originated from quantum mechanics which says information can never be lost. Me, you and all objects in the universe, carry a large amount of specific information…
The Copenhagen Interpretation: Wave Function "Collapse"
This state of existing in all possible states at once is called an object's coherent superposition. The total of all possible states in which an object can exist — for example, in a wave or particle form for photons that travel in both directions at once makes up t…
What is the Teserract
Shape Faces: 24 Cells: 8 Edges: 32 Vertex figure: Tetrahedron Vertices: 16 Properties: convex, isogonal isotoxal, isohedral Petrie polygon: octagon Tesseract is a cube in 4-dimensional space. You could also say that it's the 4D analogue of a cube. It is a 4D…
The Uncertainty Principle
Quantum mechanics states what the universe is made of while not giving an explanation of why it is that way while relativity give us an explanation of why it is what it is but does not tell us what is it made of. For example, a quantum world is defined in terms of th…
Can Faster Clocks be Observed by Relativistic Speed Rocketeers?
There is an obvious theoretical deficiency when a high speed traveller can only measure clocks in other inertial frames as running slower than their own, even if the interval as recorded by that traveller is much shorter than the non-traveller. To test this we can co…
Quantization of Gravity
Physicists are still trying to understand how spaceftime curvature emerges on macroscopic scales from a more fundamental, presumably Quantum picture of gravity; it is arguably the deepest question in physics. The Soviet theoretical physicist Bronstein , a pioneer of…
