future

The future is a time period commonly understood to contain all events that have yet to occur.[1] It is the opposite of the past, and is the time after the present.[2] Organized efforts to predict or forecast the future may have derived from observations by early man of heavenly objects. In the Occidental view, which uses a linear conception of time, the future is the portion of the projected time line that is anticipated to occur.[3] In special relativity the future is considered to be absolute future or the future light cone.[4] In physics, time is considered to be a fourth dimension.[5]

In the philosophy of time, presentism is the belief that only the present exists and the future and the past are unreal. Religions consider the future when they address issues such as karma, life after death, and eschatologies that study what the end of time and the end of the world will be. Religious figures have claimed to see into the future, such as prophets and diviners.

in it Future studies or futurology is the science, art and practice of postulating possible futures. Modern practitioners stress the importance of alternative and plural futures, rather than one monolithic future, and the limitations of prediction and probability, versus the creation of possible and preferable futures.

In art and culture, the future was explored in several art movements and genres. The futurism art movement at the beginning of the 20th century explored every medium of art, including painting, sculpture, poetry, theatre, music, architecture and even gastronomy. Futurists had passionate loathing of ideas from the past, especially political and artistic traditions. Instead, they espoused a love of speed, technology, and violence. Futuristic music involved homage to, inclusion of, or imitation of machines. Futurism expanded to encompass other artistic domains and ultimately included industrial design, textiles, and architecture. Science fiction writer Robert A. Heinlein defines sci-fi as "realistic speculation about possible future events, based solidly on adequate knowledge of the real world, past and present, and on a thorough understanding of the nature and significance of the scientific method."[6] More generally, science fiction is a broad genre of fiction that often involves speculations based on current or future science or technology.In classical physics the future is just a half of the timeline. In special relativity the future is considered as absolute future or the future light cone. In physics, time is considered to be a fourth dimension. Physicists argue that space-time can be understood as a sort of stretchy fabric that can bend due to forces such as gravity. While a person can move backwards or forwards in the three spatial dimensions, many physicists argue you are only able to move forward in time. [7]

The physicist who advised the makers of the fictional time-travel film Déjà Vu claims that a person could hypothetically travel into the future if they had a spaceship that could travel at the speed of light. After a voyage on this ship, if a person returned to Earth, millions of years would have passed in Earth time. [7] Some physicists claim that by using a wormhole to connect two regions of space-time a person could theoretically travel in time. Physicist Michio Kaku points out that to power this hypothetical time machine and "punch a hole into the fabric of space-time", it would require the energy of a star. Another theory is that a person could travel in time with cosmic strings, which are hypothetical "narrow tubes of energy stretched across the entire length of the ever-expanding universe. Many people say that time is like a fabric. Lets say there are two twins where 1 is in space going 5,000,000mph for 21 earth years but has only aged 3 years and only felt it was 3 years ,but the other twin aged 21 years. We may never understand time."
