Orbital resonance − the striking gravitational dance done by planets with aligning orbits 
It has been more than 10 billion years ago when the phenomenon known as the Big Bang occurred. However, it seems that the universe is approaching a colder direction, and the scientists are already giving a warning.
Express reports that ever since the Big Bang, the universe has since been expanding, the rate of expansion increasing over time. This is where the study of thermodynamics comes into play. There are two laws that further explain an oncoming phenomenon that would involve everyone and everything, the second law being what scientists are warning everyone about regarding the universe.
The first law of thermodynamics is that energy cannot be created nor destroyed. It can only be moved or transformed. However, the second law is that heat naturally transfers into a colder place when the two come into contact. But this second law can never be done with 100 percent accuracy. This second law is what worries scientists the most regarding the future of the universe.
When applied to the universe, it would result in dying stars and black holes, and life forms will no longer be able to exist nor survive. At the very end of it all, 100 trillion years from now, the last star will go out and resulting in a dark universe. The black holes that are left will then consume everything until there is nothing left.
Stephen Hawking theorized that when there is nothing left for the black holes to consume, then the black holes themselves will emit some radiation. This type of radiation is known as Hawking Radiation.
This raises many questions, one of which is what will happen to humans when this happens, when the black hole swallows up the universe. Express also reports that humans could be torn apart due to the gravitational pull. It bears noting that the gravitational pull of a black hole is incredibly strong to the extent that not even light can go past it.
So a person traveling close to a black hole will be stretched apart until they are swallowed in. This process is called “spaghettification.” But, the unusual thing is that the person would not be able to notice what is happening to them. Fortunately, this would be the least of everyone’s worries as the Earth is trillions of miles away from the nearest black hole.
