Science Notes

Time is a continuous flow. The moment right now becomes "past" just the next moment and the coming moment is the "future". But do the "past" and "future" really exist? You live in your present, you do everything right now. All you experience is the present, not the past or future. So think once again, does the "past" or "future" exist or is it just illusion? What exactly are they? Is it just some terminologies which humans invented to talk about time and refer to the events occurring in time? Is their no past, present or future?

It's just a sequence of events that happened. So now I want to come to the question, is time travel possible? What does it mean to time travel? If I ask you to move forward or backward or stand still in s...

The science behind human body is amazing. Some people are healthy while others are weak, some are tall while others short. Every human being has different characteristics specific to them for example like unique type of face, even though all humans have same parts which are two eyes, two ears, a nose and a mouth but they still differ too much with their faces. This is fascinating .  A human body is the best machine in the world by far. No artificial machine is as good as the biological one.  Yet it is too complex.  Many of the characteristics of human being are encoded in our Genes like height, IQ etc. Usually these Genes come from our parents and cannot be altered. But research and studies in the past have shown that genes can be altered. So what does it mean? How it will affect us? What does it mean to the future of humanity? And how can we achieve it? Let's try to figure out all the questions mentioned above. What is gene editing? It is clear from word itself, making c...
