Time Travel Paradoxes (Part-2)

An another type of casual loop paradox is "Predestination Paradox"

1.Predestination Paradox

A Predestination paradox occurs when the actions of a person traveling back in time becomes part of past events, and may ultimately causes the event he is trying to prevent to take place. This results in a ‘temporal causality loop’ in which Event 1 in the past influences Event 2 in the future (time travel to the past) which then causes Event 1 to occur.

Suppose one day your brother dies in a hit and run car accident , and to prevent this you travel back in time and reaches the place to stop your brother but accidently you hit your brother with the car and realizes that the person who hit your brother was not someone else but you. You wanted to save your brother but you were destined to complete the loop and kill your brother.

2.Killing Hitler Paradox

This paradox is quite similar to the Grandfather Paradox but this has a huge effect on everyone in the world rather than just only you.

Suppose you decided to kill Hitler but you knew about hitler because you studied about him in history , and he is in history because he did some of the worst things but if you kill him by going in the past he would be able to do nothing and nobody will know about him and you would know nothing of him and you never plan to kill hitler but if you never kill hitler he would do everything he is known for and nothing changes and you again plan to kill him but it happens again.

If you kill hitler it would have effect on whole world not just only you and after that its all chaos , nothing makes sense .

3.Fermi Paradox

The Fermi Paradox can be adapted for time travel, and phrased "if time travel were possible, where are all the visitors from the future?" Answers vary, from time travel not being possible, to the possibility that visitors from the future cannot reach any arbitrary point in the past, or that they disguise themselves to avoid detection.

One another reason why we haven't met the time travelers can be that time travel to past is not possible at all or whole concept of time travel is just not possible in reality.

Let's move the solar system - Stellar Engine

Ever thought of if we made contact with other intelligent life form , how are we gonna meet them physically with all the humans on earth? Don't worry there is a solution , and it is "Stellar Engine". Now what is a stellar engine? Simply put it is a hypothetical megastructure which uses a star's energy to propel or move the star and as the star moves the other planets will also move due the gravity of the star. The concept of Stellar engine was first introduced by Badescu and Cathcart. There are three classes of stellar engines : 1.Class A - Shkadov thruster One of the simplest examples of a stellar engine is the Shkadov thruster, or a Class A stellar engine. Such an engine is a stellar propulsion system, consisting of an enormous mirror/light sail—actually a massive type of solar statite large enough to classify as a megastructure—which would balance gravitational attraction towards and radiation pressure away from the star. Since the radiation pressure of the star wo

Accomplishments in 3-D Bioprinting

As the name suggests, in 3-D bio printing the organs or body parts or biological items are 3-D printed using special type of 3-D printers. But Now you can even print "Ebola Virus" or such other viruses as now its "Genome" is publically available. In past years what we thought as impossible is now all possible, we thought of flying cars we get it, we thought of humans in space, we did it. There are a lot of such things that we think today are impossible, but one day they will be possible. Who would have thought that we will be printing viruses but we did. But the much it sounds exciting, it is that much dangerous too as it can be a huge danger to the humans. So we should be careful while handling such a technology.

What are Antiparticles? Is there something that we should worry about?

Simply put , antiparticles are the opposite of the subatomic particles but with different charge and different magnetic properties . For example the antiparticle of electron is a particle with same mass but different charge , in this case positive charge and it is commonly referred to as Positron.. While the electron has a negative electric charge, the positron has a positive electric charge, and is produced naturally in certain types of radioactive decay . The opposite is also true , the antiparticle of the positron is the electron. Particle–antiparticle pairs can annihilate each other, producing photons ; since the charges of the particle and antiparticle are opposite, total charge is conserved. For example, the positrons produced in natural radioactive decay quickly annihilate themselves with electrons, producing pairs of gamma rays . It is not possible to create an antiparticle without either destroying another particle of the same charge (as is for instance the case when antipa
