# Space And Time In Physics

## Galileo used space and time in his memoirs in terms of its speed and acceleration. As a result, space and time have entered mathematical equations as very important quantities in physics.

Space and time are very important concepts in science and physics. We need space and time to describe an event. If we do not know where and when the incident took place, we will not get a clear idea about the incident. The concept of space has been around since ancient times to understand where an object is located and how much space it occupies. It takes time to understand what happened before and what happened after and for how long.

**Euclid's idea:**

Euclid was the first to present the geometric concept of space. Everything around us is space.

**Galileo's idea:**

Galileo used space and time in his memoirs in terms of its speed and acceleration. As a result, space and time have entered mathematical equations as very important quantities in physics.

**Newton's idea:**

The concept of space and time has become more clear and quantitative through Newton's mechanics. In Newtonian or classical physics, space is a three-dimensional extension. There is no beginning or end to space. Infinite's expansion. Space can be divided into very small parts, that is, space is uninterrupted. Space homogeneity means that any area of space is identical to another area. Space neutral. All events occur in space and the position of all objects within the expansion of space but space is not affected by any object or event. As space and objects are neutral, so time is neutral, so the flow of time cannot change space.

According to Newton, time will flow in its own way. This temporal flow is not caused by any object or event. Time has no beginning or end. Time can be divided into very small parts. That is, its flow is uninterrupted. Any part of the time is similar to any other part. As a result, whenever a test is performed, it does not depend on time selection. Time-space neutral.

Newtonian Space In terms of time, our universe consists of three-dimensional space and one-dimensional time. Where all events are happening and all objects are contained.

The concept of Newtonian space-time has changed in modern physics. At its core are Einstein's theory of relativity and Planck's quantum theory.
