Auroras
Auroras is a natural luminous phenomenon where natural light is displayed in the sky. They are mostly seen in the higher latitudes (near Arctic and Antarctic regions). They are called Aurora Borealis in Northern and Aurora Australis in Southern Hemisphere.

Features

  • Green is the most common colour in auroras and they produce faint sounds of claps, crackles and static sounds.
  • The name is derived from the name of the Roman goddess of the dawn, Aurora. As per the myth, she travelled from east to west to announce the arrival of the sun.
  • Boreas is the Greek term for the north wind
  • Auroras are visible from space. Planets like Jupiter, Saturn, Uranus and Neptune also have the same phenomenon.

Cause

  • They are caused by “powerful electromagnetic waves during geomagnetic storms,” according to a study by Iowa University. Geomagnetic storms on the Sun disturbs the magnetic field of Earth.
  • These disturbances produce electromagnetic waves, known as Alfven waves, which accelerate electrons and produce these lights.
  • This theory, called Landau damping, was proposed by Russian physicist Lev Landau in 1946.

In History

  • According to Scandinavian legends, these lights served as a gateway to Valhalla. In Norse mythology, Valhalla is believed to be the place where martyred soldiers spent their afterlife.
  • It is considered a bad omen in European Culture. Blazed red lights were visible over the British Isles a week before the French Revolution started.
  • In Japan, a child born during the northern lights is believed to be blessed with good looks, intellect and good luck.

How Are Global Nations Trying To Control Big Tech?

How Are Global Nations Trying To Control Big Tech?

The G7 nations recently met to address tax avoidance by big tech companies. Tech companies have been using ‘Tax Havens’ for many years to reduce their federal tax liability. Let’s have a look at how G7 decided to crackdown on tech companies and other MNCs doing tax avoidance.

Crux of the Matter

What is The G7?
Group of Seven is an informal group of world’s 7 largest developed democracies. The objective is to address issues regarding world economy. G7 includes United Kingdom, United States, France, Canada, Germany, Italy, and Japan.

G7 Summit 2021
G7 made a “historic” deal for taxing multinational companies. This deal was made to prevent tax avoidance by making MNCs pay tax in the country they operate. Countries will now charge 15% minimum corporate tax rate on the MNCs.

How Tech Giants Are Taxed?
They are taxed based on where they are headquartered. The international tax system, since pre-digital era, focused on labour, production and capital. In case of tech companies, no physical product is produced and thus identification of where economic activity is taking place is difficult.

Tax Havens
It is a place where tax rates are low. Tech companies set-up shell companies in such countries and channel their profits through them. Countries lose around $427 billion every year due to tax evasion (2019) whereas India lost around $10 billion due to similar evasion (2019).

Problems With The Proposal
Some countries rely on low taxation rates to attract foreign investments. Global minimum taxation rate will take away the tool which these developing countries have. This will slow down the economic growth of such countries.

Impact On India
It won’t affect the MNCs doing business in India as India’s effective corporate taxation rate is higher than the global minimum tax rate. India attracts foreign investment through cheap labour rates and large internal market instead of lower taxation rates.

War In India – Google Tax
Tech giants can avoid paying 6% ‘Google tax’ in India if they set-up an Indian unit. The new IT rules also compel tech companies to set up Indian units for grievance redressal. However, if they set up Indian unit to avoid Google tax or for grievance redressal, they will be taxed at a higher rate of 40%.
