What are northern lights or Aurora Borealis

Ever wondered, what is that bright dancing light on the North Pole?   Where does it come from or is a miracle of God. We don’t know whether it’s a God’s miracle or not, but it’s a miracle indeed for the spectators. In simple words, The Aurora Lights result of electrically charged particles from the sun entering into earth’s atmosphere. These lights are popularly known as the’ Aurora Borealis’.

Auroras that are visible in the northern hemisphere are known as ‘Aurora Borealis’ or simply ‘Northern Lights’, and the Aurora that transpire in the Southern hemisphere are called ‘Aurora Austarlis’ or simply ‘Southern Lights’.   

Aurora lights are visible in numerous colors such as red, yellow, blue, but the pale green and pink are most common color shades. The miraculous part of the Aurora lights is the patterns it creates in the sky in the forms of arcs or as the scattered colors on the expressionist painter’s canvas.

Its so fantastically amazing that simple science between colliding gases in the earth’s atmosphere can create the such a magnificent sight.  Colors of Aurora depend upon the colliding gases. Aurora lights extended from 80 kilometers top as high as 600 kilometers over the earth’s surface.

What is space-time?

What is space-time or what is space-time continuum are mathematical representations that merge time and space as a one thing.  We consider our world as a three-dimensional and if we count time as a dimension then it becomes fourth dimension

If we look at multiple theories regarding the space-time we can easily see that time represented as a stable gateway, which is free of motion or an observer. However, if we put this theory in realistic context then it’s proven that it’s impossible to separate time from the existing three dimensional world. There are multiple elements comes into play when we calculate the time.

If you are looking a plane, flying over your head it will not feel that fast to you from your point of view but to people sitting inside the plane they won’t even realize that they are even moving but a person on watchtower certainly sense the incredible speed. This example might prove the point of passing time depend on the object’s velocity and observer and gravitational force.     

One thing to consider space-time just exist it does not evolve. This is a line from the past to future, which shows three-dimensional position at every point in time. The line does not change the time it exists as an enduring entity.  Because combining time and space we can easily locate any incident in history with help of time and space.
