Sonic the Hedgehog CD

Sonic the Hedgehog CD (ソニック・ザ・ヘッジホッグCD, Sonikku za Hejjihoggu Shī Dī), or Sonic CD (ソニックCD, Sonikku Shī Dī), is a platform video game developed by Sonic Team and published by Sega originally for the Sega/Mega-CD in 1993. It is the first game in the Sonic series to make use of the CD-ROM format, featuring high quality audio and full motion video. Development began in Japan around the same time as Sonic the Hedgehog 2 in the United States. Originally, the games had many similarities, but over time became vastly different projects.

The story of Sonic CD follows Sonic the Hedgehog as he utilizes time travel to save Amy Rose and Little Planet from Doctor Eggman and Metal Sonic. The game features the debut appearances of Amy Rose and Metal Sonic, both of whom have gone on to become recurring characters in the Sonic series. Time travel is a key aspect to both the story and gameplay, with nearly every stage containing four different variations (one for each time period) featuring alternate stage layouts, music, and graphics.

Future

The future is what will happen in the time after the present. Its arrival is considered inevitable due to the existence of time and the laws of physics. Due to the apparent nature of reality and the unavoidability of the future, everything that currently exists and will exist can be categorized as either permanent, meaning that it will exist forever, or temporary, meaning that it will end. The future and the concept of eternity have been major subjects of philosophy, religion, and science, and defining them non-controversially has consistently eluded the greatest of minds. 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. In special relativity, the future is considered absolute future, or the future light cone.

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 such as prophets and diviners have claimed to see into the future. Organized efforts to predict or forecast the future may have derived from observations by early man of heavenly objects.

Data

Data (/ˈdeɪtə/ DAY-tə, /ˈdætə/ DA-tə, or /ˈdɑːtə/ DAH-tə) is a set of values of qualitative or quantitative variables; restated, pieces of data are individual pieces of information. Data is measured, collected and reported, and analyzed, whereupon it can be visualized using graphs or images. Data as a general concept refers to the fact that some existing information or knowledge is represented or coded in some form suitable for better usage or processing.

Raw data, i.e. unprocessed data, is a collection of numbers, characters; data processing commonly occurs by stages, and the "processed data" from one stage may be considered the "raw data" of the next. Field data is raw data that is collected in an uncontrolled in situ environment. Experimental data is data that is generated within the context of a scientific investigation by observation and recording.

The Latin word "data" is the plural of "datum", and still may be used as a plural noun in this sense. Nowadays, though, "data" is most commonly used in the singular, as a mass noun (like "information", "sand" or "rain").
