Space Time Continuum and Wormholes

  SPACE TIME CONTINUUM : Vidushi Mishra | thesocialcomment  ESA - Spacetime curvature




            Imagine universe as a sheet of fabric. On which if we keep any object, it bends due to its gravity or mass. This fabric has four-dimensions - length, breadth, height/depth. The other dimension is time, which is not exactly a dimension but is taken so. In image 2, there is a red planet (assume it to be mars) which is causing the fabric to bend, this is due to mass and also the gravity of Mars. Now take a look at the yellow ball (assume it to be sun), what do you observe. The curve of the sun compared to that of mars is greater. This is because the sun has more mass, hence more gravity while mars.

                 Now, this picture explains us a lot. Firstly, the sun has a lot of mass and gravity than the earth. Secondly, if we were to perform a miniature of the same experiment on trampoline, with two balls having different masses (one is lesser than the other). When we drop the two balls, the ball with less mass tends to move towards the one with more mass, due to the slope.

              The same is the case with our earth, it tends to move not only because of sun's gravity, but when we apply space time continuum concept, it moves due to the slope. We do not fall into sun as sun pulls us by our gravity but we miss falling into it. How? Take a thread and tie it to anything spin it around. What do you observe? We pull the thread but it isn't falling into our hands, this is due to centripetal force. 

              The Space Time Continuum concept is really interesting and amazing. One such interesting thing related to it is a Wormhole. Wormholes are the holes (rather a theory) that explains teleportation (moving from one place to another). Look at the picture below:

              This is a theoretical wormhole, which explains teleportation. Consider the place with blue color is a dimension or a place and the yellow one is another, there is a gap that connects the two places. The U-shape is formed by gravity. The more the U, the more the gravity and vice versa. 

What effect does a black hole have on the fabric of space time? - Quora

              There may be a chance that black holes are a type of wormholes. But here nature comes to rescue. The deeper the U the narrower the path. This means that if we were to find a wormhole we would be spagettified. Spagettification is where you will become like a noodle, this is caused due to the narrowness of continuum. We experience this at the singularity of a black hole also.

Black Holes, Gravity and Time (Part - 3)

Image
                                         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 ...

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 col...
