CYCLONE
Primary Hazards:
Primary hazards include strong winds, heavy rains, and storms. The sea level rises abnormally near the coasts as a result of which the low-lying areas near the coastal regions get submerged, drowning humans, their live stocks, and their inhabitations, destroying vegetation and soil fertility. Very strong winds damage the houses, trees, communication systems etc. resulting in huge loss of life and property.
Secondary Hazards:
Secondary hazards include floods, fire, and freshwater flooding. Heavy and prolonged rains cause floods in rivers which cause submergence of the nearby inhabited regions, erosion of valuable farming lands and destruction of buildings. Strong winds in forest regions result in forest fires which spread with the intensity of cyclonic winds.

HOW TO TIME TRAVEL
We have many ways to time travel but none of them is proved yet
- Traveling with the speed of light: According to the theory of relativity when an object travel with the speed of light, time passes slower for him than others.
- Huge gravity: when gravity become huge like of black hole, light also can't escape from its gravity and time become slower for an object approaching towards that huge gravity area.
- Multiverse: according to Quantum Mechanics multiverses exists. There is not a single universe where time changes but there are multiverses and in different universes different timelines exists.
- Tipler cylinder: according to american physicist Frank Tipler, if we move around a cylinder of infinite length having electric and magnetic fields then we can go in future or past.
- Wormholes: from centuries peoples thought that wormholes are roads built in higher dimensions that connects time and space.
- God particle: on 14 March 2013, scientists discover Higgs boson and they believed that this particle can do time travel.
- Cracks in universe: astronomers found that there are cracks in the universe wich can give birth to time loops.
- Black Holes: due to huge gravity of black holes physicists think that the trough it we can do time travel.

FALSE MEMORY
In the first test, 45 participants were randomly assigned to watch different videos of a car accident, in which separate videos had shown collisions at 20 mph (32 km/h), 30 mph (48 km/h) and 40 mph (64 km/h). Afterwards, participants filled out a survey. The survey asked the question, "About how fast were the cars going when they smashed into each other?" The question always asked the same thing, except the verb used to describe the collision varied. Rather than "smashed", other verbs used included "bumped", "collided", "hit", or "contacted". Participants estimated collisions of all speeds to average between 35 mph (56 km/h) to just below 40 mph (64 km/h). If actual speed was the main factor in estimate, it could be assumed that participants would have lower estimates for lower speed collisions. Instead, the word being used to describe the collision seemed to better predict the estimate in speed rather than the speed itself.
The second experiment also showed participants videos of a car accident, but the phrasing of the follow-up questionnaire was critical in participant responses. 150 participants were randomly assigned to three conditions. Those in the first condition were asked the same question as the first study using the verb "smashed". The second group was asked the same question as the first study, replacing "smashed" with "hit". The final group was not asked about the speed of the crashed cars. The researchers then asked the participants if they had seen any broken glass, knowing that there was no broken glass in the video. The responses to this question had shown that the difference between whether broken glass was recalled or not heavily depended on the verb used. A larger sum of participants in the "smashed" group declared that there was broken glass.
In this study, the first point brought up in discussion is that the words used to phrase a question can heavily influence the response given. Second, the study indicates that the phrasing of a question can give expectations to previously ignored details, and therefore, a misconstruction of our memory recall. This indication supports false memory as an existing phenomenon.
Replications in different contexts (such as hockey games instead of car crashes) have shown that different scenarios require different framing effects to produce differing memories.
Conclusion: False memory is a phenomenon where a person recalls something that did not happen or recalls it differently from the way it actually happened. Suggestibility, activation of associated information, the incorporation of misinformation and source misattribution have been suggested to be several mechanisms underlying a variety of types of false memory phenomena.
False memories are a component of false memory syndrome (FMS).

FUTURE OF HUMANITY
FUTURE OF HUMANITY
Talking about the future of humanity fantasies all of us because all of us want to know that what will be the next level of humanity. Many a time when we think about our ansisters who live into a cave then we have a curiosity to know that will be our future.
Actually it is very difficult to make predictions but after analysing a lot of things we can make a prediction which can be accurate a lot. So to predict the future we have to understand how our ansisters of 1900 think of us, they will think we are wizards or sorcerers who have magic mirrors called mobile phones, flying carpets called jet airplanes.
So, i think if we look our descendant of 2100 they will be look like hindu gods like Hanuman who is immortal because i think in future the genetic engineering will be so adwance that we can take out the age causing geans out of our DNA anf became immortal.
Like Sanjay of Mahabharata, we will have more advanced drones who don't need any type of maintenance or they be self healing as today we are at the point where Lamborghini has created the world's first self-healing sports car. The Terzo Millennio, which translates as third millennium in Italian, has the ability to detect and repair cracks in its body work.
I think that the industries which will be the biggest in 2100 are mainly ARTIFICIAL INTELLIGENCE, NENO TECHNOLOGY, BIO TECHNOLOGY.
Ofcourse, now most of you have a question that will one day A.I became dangerous for humanity? Yes, but only if they become self aware. I think until they become self aware they are like workers for us. Also you have a question that will it reduce employment? No, because A.I reduce employment in one sector but increase employment in another sector. For example, when automated teller machine (A.T.M) was introduced people thought it will reduce employment in banking sector. But some times predictions also fail for example when internet was first introduced at CERN (the European Organization for Nuclear Research) so that scientists from all over the world can share their reserch and public thought that one day internet become a place for high culture art and society but today we all know that around 4% of internet if only filled by pornography.
