Humans have been fascinated towards time travel and have been developing technology to make it possible one day. The advancement in science has helped humans to make ideas turn reality. Space has always been a mystery to humans and we have always tried harder to solve them at the best of their possibilities. The idea of time travel and humans’ moment to past or future seems to be very fascinating, and humans believe that it is possible. But the fact that we cannot travel back to the era or to the future lies in the Einstein Theory Of Relatively. Which states that nothing can travel faster than the speed of light or in simple words it suggests that anything which is travelling with the speed less than light will never be able to move faster in it’s coming time or else to do so it requires enormous and endless power sources which we know that is not possible.
But different findings have led the belief of scientists to increase in this area and make those possibilities to be true. It is believed that we can move to other planets or parallel universes through a wormhole. Which is another hypothesis as their significance is still not found. Scientists believe that by creating a wormhole we can reach other planets and even past . There have been particles like tachyons (Hypothetical) which are supposed to move faster than light. It is believed that with the help of these we can send messages to our past and even travel one day.
Here’s is the paradox which do makes rise a potential question to do so. This is known as the Grandfather Paradox. According to this paradox it states the idea that if any person travels to time before their grandfather or sends a message before grandfather had children and if someone through that message kills their grandfather, it would raise a question to their existence. This paradox has been in discussion since ages and is considered a proper problem which really raises the question and theories related to time travel.
Scientists have been working in this field of developing technology and doing research so as to rediscover particles or any technology which could help us to cross the barrier of time and travel in different years. But this is purely hypothetical since scientists do know that it’s hardly possible to cross the barriers of light and travel faster than it. We need enormous sources of energy or endless sources of energy to run any machine at a speed faster than it. It is still a belief of fiction but people do believe that whatever is thinkable can be achieved so scientists are working in discovering various other phenomena happening in space so as to get the idea of how space works and utilize those knowledge in future projects. The wormhole theory is a relevant theory which does enable human travel to other planets outside our solar system without breaking the famous theory of relativity but still we hardly find any wormholes and if they exist, they are expected to be very small enough for any spacecraft to enter.
Scientist’s have been finding out different ways so as to make their dream turn reality. It does seem to be impossible but still some people have faith in their work and theories. Science has been bringing out hidden secrets about space with every trip of humans in it. Maybe in future we may be able to do time travel with better technologies, and thus new possibilities and opportunities for mankind
