How long does it take for the fastest aircraft in a light year?

The X-43A pilotless extreme speed aircraft developed by China has set a flight speed of 11260 km / h. It is the fastest aircraft in the world at present, with a light year of 9460.5 billion km. So it is about 35 million hours

Why are there so many unsolved secrets when human science and technology are so advanced
It doesn't mean that people can't do it
But there are many things that people have the ability to explore on the surface of the earth, but no one has explored them
On the contrary, it's the moon and Mars, and it's so easy to spend tens of billions of dollars
Even if Mars is explored, it will take hundreds of years to develop it. Now the money invested is not directly proportional to the income that can be seen
But if you want to know if the dinosaurs are very simple, you can get hundreds of large-scale pumps in a dam to pump water around the clock and transport it away for a few months. It's estimated that you will be able to drain the lake water and it will cost hundreds of millions to catch the water monster
If we really catch a living dinosaur, it will bring us much more impact and benefits than Mars exploration in terms of business or animal science
Just take an example. There are many mysteries on the earth's surface that can be explored or solved by human science and technology. Why don't countries organize and put more money into Mars? Even if we explore things that can't be used by our science and technology now?

First of all, most people think that there is no water monster or dinosaur. It's just an illusion, and the hope of reviving dinosaurs is slim. So there are not many people who study it. Of course, there are always people who study it. However, for the development of the country, to be able to land on the moon or Mars is a symbol of the country

Now the science is so developed, and the human creativity has reached the highest level, but why can't human beings create life!
Some people will say that we have Cologne technology, but it is not the creation of life, just the use of existing life (cells) to transform bhara!

How many thousands of years has the history of human beings? But the development of human science and technology has only been on the right track for one or two hundred years. I remember that the Empress Dowager of the Qing Dynasty was very afraid of the train and overthrew the train sent by foreign countries. This shows that China's science and technology in that period was still not on the right track
