Mind Blowing Facts About Physics
The contribution of Physics in unraveling
mysteries of the universe and its constituents has been tremendous and
greatly remarkable. Discoveries made by the Physicists over the years
have helped us a great deal in understanding both micro and macro
cosmos. The discoveries, such as Planck’s constant and natural unit of
light, have opened the Pandora’s Box around us to reveal other facts as
well. Here is a list of top 10 mind blowing facts about Physics that
will literally surprise you.
10. Light waves don’t always move in straight lines:
It is generally believed that light waves only move in straight
lines. However, as per the recent research in 2010 using computer
controlled hologram, it has been proved that light, too, can get twisted
into knots. According to the study, when light passes through the
hologram, it twists into different shapes, producing multiple knots.
9. Unbelievable hydrogen energy:
It is estimated that Sun burns around 620 million metric tons of
hydrogen/second into 616 million metric tons of helium. Out of this
total volume, around 4 million tons of mass enters the solar system.
Furthermore, only about 3.6 pounds of the mass reaches our earth. Had
even 1 percent of the energy produced out of fusion reached us, what
would have been the scenario?
8. Human radiations:
As per the recent studies and discoveries in the field of Physics, a
nude human body constantly radiates around 1000 watts of heat and
absorbs about 900 watts. However, once the person covers his body with
clothes, the outflow of the heat flux reduces considerably due to the
exterior barrier. The amount of heat outflow from the human body is more
than enough in lightning up a 100 watt bulb for some time.
7. Anti-gravity movement:
Water can easily run against the gravitational pull when moving up
narrow pipes. The process is described as ‘Capillary Action’. Water
moves up in the narrow spaces without any assistance and against the
gravitational force. This ability of the liquid proves that
gravitational force can’t control the movement of every matter present
on earth. At times, other forces (Surface tension, in this case) can
defeat it.
6. Viscous fluids can flow at high speeds:
It is generally believed that viscous fluids can’t flow fast enough
like water – a liquid with reduced viscous level. However, some
scientists went on to prove that fluids like “Ketchup” can attain high
speeds, too, if constantly sheered over a period of time till they
attain momentum. Once thrust is achieved, the viscous forces dwindle
down considerably and free movement is observed.
5. Gravitational constant:
The standard value of the gravitational constant is 9.8 m/s^2. It
must be well known to all the science students that the value is
calculated from the free fall of an object at sea level. The point worth
noting is that the free fall should be at latitude of 45 degrees from
the base level in order to obtain this value than 90 degrees as believed
by the most.
4. Air current:
The speed of wind near the surface of ocean is much lower than what
is observed in the higher altitudes. The reason can be attributed to the
friction it receives from the water surface. It is due to this reason
that most birds fly at a higher altitude. They manipulate the wind power
in order to use least amount of energy on flying.
3. Universe is a Computer:
On the basis of a paper published by a professor in MIT, the Universe
is equivalent to a computer. The figure is roughly equal to 10^120
bits. The number was calculated by him on the basis of the amount of
information that can be stored in a volume just before it adopts the
properties of a black hole. The information can be equated to absolute
entropy of the universe.
2. Mystery of microwave and liquids:
As per the latest researches worldwide, water in the liquid state has
the characteristic to enable many new molecular interactions to
develop. This helps in enhancing absorption of heat by food items. Due
to this property, foods items like burgers become soft enough to be
eaten after coming out of microwave ovens.
1. Ultimate expansion:
It is proved by scientific theories that the universe is constantly
expanding. It is expanding at a decent pace and it is believed that
galaxies will evaporate in the coming 10^19 to 10^20 years. It has been
learnt from a number of theories by different Physicists worldwide that
only White Dwarfs (a type of star) would be able to survive as their
lifetime is more than 10^32 years.
