Amazing science facts that will blow your mind

20% of Earth's oxygen is created by the Amazon rainforest 

The Amazon rainforest covers 5.5 million square kilometers (2.1 million square miles) of Earth 

Our environment is comprised of around 78 percent nitrogen and 21 percent oxygen, with different gases present in little sums. Most by far of living creatures on Earth need oxygen to endure, changing over it into carbon dioxide as they breathe. Thankfully, plants persistently recharge our planet's oxygen levels through photosynthesis. Amid this procedure, carbon dioxide and water are changed over into vitality, discharging oxygen as a result. Covering 5.5 million square kilometers (2.1 million square miles), the Amazon rainforest cycles a noteworthy extent of the Earth's oxygen, engrossing huge amounts of carbon dioxide at a similar time. 

Some metals are reactive to the point that they detonate on contact with water 

This is the thing that happens when sodium responds with water 

There are sure metals – including potassium, sodium, lithium, rubidium and caesium – that are reactive to the point that they oxidize (or discolor) in a flash when presented to air. They can even create blasts when dropped in water! All components endeavor to be artificially steady – at the end of the day, to have a full external electron shell. To accomplish this, metals will in general shed electrons. The soluble base metals have just a single electron on their external shell, making them ultra-quick to pass on this undesirable traveler to another component by means of holding. Accordingly they structure mixes with different components so promptly that they don't exist freely in nature 

A teaspoonful of neutron star would weigh 6 billion tons 

Neutron stars contain probably the densest issue in the known universe 

A neutron star is the leftovers of a huge star that has come up short on fuel. The withering star detonates in a supernova while its center crumples in on itself because of gravity, shaping a super-thick neutron star. Cosmologists measure the astoundingly huge masses of stars or systems in sun based masses, with one sun powered mass equivalent to the Sun's mass (that is, 2 x 1030 kilograms/4.4 x 1030 pounds). Commonplace neutron stars have a mass of up to three sun based masses, which is packed into a circle with a sweep of around ten kilometers (6.2 miles) – bringing about the absolute densest issue in the known universe.
