Do lines exist in the real world?

Lines don’t exist in reality, neither straight nor curved. They exist as drawn or written, in oral language (as the word “line”), in perception, or imagination. Think about it: what are examples of a line?

How many world lines are there?

In this story, there are four different worldlines known as the black line, blue line, red line, and green line. Gary Jackson exists in four different worldlines.

Is it possible to have a straight line?

A straight line is nowadays defined in a abstract way, using axioms: By two distinct points of the plane passes one and only one straight line. Any straight line contains at least two points. There are at least three non-aligned points.

What is the importance of world line?

In addition to plotting the position and velocity of the particle as a function of time, we can also indicate the particle’s trajectory on a space-time diagram, using something known as a world-line. The world-line of a particle is just the curve in space-time which indicates its trajectory.

Does the number I exist?

An “imaginary number” is a multiple of a quantity called “i” which is defined by the property that i squared equals -1. This is puzzling to most people, because it is hard to imagine any number having a negative square. Imaginary numbers do exist. Despite their name, they are not really imaginary at all.

How did Okabe wake up in 2036?

Apparently somehow Daru and Maho have managed to find a backup of Okabe’s memories from 2011 from when the Time Leap Machine failed to blast him to the past, and implanted them in his 2036 body so it wakes up.

Does Kurisu remember?

Kurisu remembering Okabe is at most vague. In the OVA, it was shown that she doesn’t remember much. But the possible explanation is perhaps her memories seemed “deja vu-ish”.

Is there a perfect line?

Straight lines and perfect circles don’t exist in reality; they are mathematical abstractions. Therefore, there is no perfect line or circle in the entire universe (and unless you count imperfect shapes that constantly change at the quantum and molecular level as “perfect”).

Is a circle made up of straight lines?

A circle is a plane figure contained by one line, which is called circumference, and is such, that all straight lines drawn from a certain point within the figure to the circumference, are equal to one another.

Is space time curved?

In general relativity, spacetime is not ‘flat’ but is curved by the presence of massive bodies. The curvature of spacetime influences the motion of massive bodies within it; in turn, as massive bodies move in spacetime, the curvature changes and the geometry of spacetime is in constant evolution.

How many dimensions are there in space time?

three dimensions
In physics, spacetime is any mathematical model which fuses the three dimensions of space and the one dimension of time into a single four-dimensional manifold. Spacetime diagrams can be used to visualize relativistic effects, such as why different observers perceive differently where and when events occur.
