Time travel has always been a fascinating topic to think about. Will we ever be able to see the future or travel back in time? Would there ever be a time machine or are there any other means to travel through time? What would be the consequences of time travel? What is the Grandfather Paradox? These are just some of the questions that arise when we talk about time travel. But let's start from the beginning.  Sir Issac Newton is considered the greatest scientist of all time. His understanding of Gravity is one of the major leaps in the field of physics. He came up with the Inverse Square Law based on the works of Kepler who told that the celestial bodies "somehow magnetically" moved in an elliptical path around the Sun. Newton wasn't satisfied with the explanation and studied the revolution of the Moon around the Earth. His theory states that the gravitational force of an object depends on its size and the distance between 2 objects. But he always believed that gr...

In the present day and age, waking up and not using a mobile phone is almost unheard of. Smartphones now have such an enormous impact on every aspect of our life by making everything so easily accessible at the palm of our hands. The smartphones now have more computing power than most laptops. But how did it all begin? The Motorola DynaTAC 8000X . In 1984, it became the first commercially available handheld cellular mobile phone. A full charge took roughly 10 hours, and it offered 30 minutes of talk time. It also offered an LED display for dialing or recall and could store 30 phone numbers. It weighed 794 g and stood 33cm high. It cost a whopping US$3995, which after adding inflation would cost $9912 in 2020. Though the creator, Martin Cooper, made the world's first phone call in 1973, which weighed around 2kg, it took the company over a decade to bring it to the market. Now we have a phone that is smaller than your thumb! Zanco tiny t1 claims to be the smallest phone in the mar...

As we all know, our computing power is increasing day by day. It was just 77 years ago when the first computer, ENIAC, was invented which occupied 1800 square feet in area and weighed at a whopping 50 tons. Now we have computer systems that are presently computing the combinations of various compounds that could control the spread of the Corona Virus. They run for tens of hours connected to multiple CPU's and run multiple combinations at the same time. And the technology to construct complex simulation games are up and booming. We are able to create games where we give a character a set of missions to accomplish. Now imagine a day when you can create a simulated world so perfectly, containing humans and other life forms as real as you and me, to a degree where you can put together every single neuro-synaptic thought that a person can have and also giving that character the perception of free will! Give that line another read .  This is called the Simulation Hypothesis , where we...

43 years ago, NASA launched 2 space probes, named Voyager 1 and Voyager 2 , in consecutive months which became the 3rd and 4th man-made objects to ever cross the Heliosphere (the region within which the Sun's magnetic field is prominent). This sphere is stretched around 18 billion kilometers from the Sun. This sphere contains the magnetic field and the solar wind that protect the Solar System from Interstellar Wind. This protective sheath is called the Heliosheath. We are not going to bother you with the details of the launch and the specifications of the space shuttle. We are here to talk only about the interesting facts and most importantly,  The Golden Record. 1. Voyager 1 is the most distant man-made object from the Earth currently at 22.3 billion kilometers . It is traveling at 17 km/s which is greater than the escape velocity of the Earth. 2. If it stays on the same course as now, it would take about 40000 years (yes, you read that right. 40000 YEARS)for Voyager 1 to ...
