Date: 18/05/2022: exploring the universe by the nano technology (own thought )
I wonder many times why exploring the universe is so important and why large hands like NASA and ISRO spend a huge amount of money on sending rockets into space. Later, I came to know that to survive mankind for a large scale of time being only depending on earth is not very safe, so mankind is trying to make life multiplanetary. Due to continuous reactions in the sun, the size of the sun keeps increasing for many years and after some billion years, approximately 7.2 billion years, the sun will add earth into itself. So being on a single planet wasn't safe enough, but from the latest information from astronauts is that before that 7.2 billion years a nearby galaxy called aroma will collapse to our milky way galaxy. The distance of our galaxy to travel edge of galaxy is approximately 20000 light years (light years =distance travelled by a light in one year). If we look into present technology, there aren't pleasant energy sources like petrol, helium to travel such a large distance. Even if we have an energy source, it took a very long time to travel. It's almost impossible to travel larger distances with the present technology, and the only other way that the present astronaut claiming is to travel by the warmhole which is proved in eistein theories is not found yet in reality, but after some million years, man may come with new technology to achieve this destination. But while knowing all this information, something like this strikes into my mind, if you travel at a light speed, your mass will become into infity that means if you make a rocket to move in infinity velocity, its mass will become infinity, but by using advanced technology, something like nanotechnology, if a rocket is made into size smaller, which has almost no mass. (like mass reduced in the millions of transistors to fit in microchips) If it can make into the size of almost photon it will travel as fast as light. And I think this will reach out of the galaxy in a shorter time at the speed of light.
