Human wisdom always led us to explore secrets of our universe. In fact, it is the power of knowledge and science that living on the Earth that we can know how big and far our solar system is within the unimagined boundaries of the universe. Studying our solar system can take a human being into an awesome realization that science today completely dominates new horizons of development.
How science and new developments expanded their wings to explore other worlds as compared to the well-being of our very Earth is a big question mark. Let's first see how sciences go above Earth!
You might feel it as a journey of our solar system for a while and think about the power of science and development in today's world.
A commercial cruising aircraft flies at a height of 13 km, where the limit of troposphere ends. A typical weather balloon flies at a height of 27 km, whereas the highest skydive so far has been made from the height of 31km.
Stratosphere ends at 50km height and mesosphere at 90km.
Beginning of low orbit starts at 160km. The international space station works at the height of 406km and hubble telescope exists at 598km.
The limit of thermosphere ends at 600km and exosphere at 10,000km.
2,000km is the end limit of low orbit and a communication satellite works at the height of 35,786km.
Magnetosphere ends at the height of 50,000km.
Now let's go further up. The distance Asteroid 2005YU55 passed from the Earth in November 2011 and was 324,600km, while our moon is at the distance of 384,000km from the Earth. The farthest travel a human could do till now from Earth is 400,000km.
Wouldn't it be interesting to go millions and billions of kilometers further? Human wisdom not only discovered that our Sun lies at the distance of 149.6m km but also could be able to send a mission Voyager 1 probe at the distance of 17.94b km, which is the farthest man-made object beyond the Pluto and Neptune.
The heliosphere ends at the distance of 21.24b km, which is the outer edges of our own solar system!
Going through this wonderful journey of human success and development far in stars, the reality is that our solar system is still one of the tiny parts of the universe. Science continues to explore the secrets of universe expansions.
Today, we rejoice that our science and development has gone beyond the boundaries, which is unbelievable and amazing. However, achieving all those successes, did we ever think of a moment about those people who live just as close to us on Earth? How new science thinks of the extremely poor who are starving on Earth or those who have become more vulnerable to extreme weather events than the past?
Perhaps we have gone too far along with our so-called development but forgot the challenges and protection of our mother Earth. Today we see people living with hunger, poverty and diseases. Today our Earth faces the challenges of global warming and extreme weather events. Can the advanced science help the poor to protect from the impacts of climate change?
We do celebrate Earth Day every year, however we perhaps forget that our Earth also asks us to recall our responsibilities and take action to protect our Earth from the on-going global pollution. Did we ever think we, the entire world, emit 90 million tons of CO2 every day? It would be good for science to reach up to Neptune. Let's also think how good we are for our neighbors.
