How accurate is this video about higher dimensions?

In summary, scientists use mathematical models, theories, and observations from particle physics and string theory to support the existence of higher dimensions. Humans have difficulty visualizing higher dimensions, but can use concepts like projection and rotation to help understand them. Visual representations of higher dimensions in videos are helpful but not completely accurate. Some scientists suggest that parallel universes or alternate realities could exist in higher dimensions, but there is no empirical evidence to support this. Understanding higher dimensions has practical applications in fields such as physics, engineering, and computer science, and can also challenge our perception of reality and expand our understanding of the universe.

I thought it was pretty straightforward until 4:26, until they started making some questionable claims. I'm no expert so I thought I'd ask here.

I am also very curious about this, as this video has been on my mind ever since I saw it a few years ago.
 

1. How do we know that higher dimensions exist?

Scientists use mathematical models and theories, as well as evidence from particle physics and string theory, to support the existence of higher dimensions. Additionally, observations of gravitational effects and the behavior of subatomic particles provide further evidence for the existence of higher dimensions.

2. Can we visualize higher dimensions?

It is difficult for humans to visualize higher dimensions, as we are limited to three dimensions in our perception. However, concepts such as projection and rotation can be used to help visualize higher dimensions in a simplified way.

3. How accurate are visual representations of higher dimensions in videos?

Visual representations of higher dimensions in videos can be helpful in understanding the concept, but they are not completely accurate. These representations are often simplified and do not fully capture the complexity of higher dimensions. Additionally, they may be based on theoretical models that are still being studied and debated by scientists.

4. Are there real-life examples of higher dimensions?

Some scientists suggest that the concept of parallel universes or alternate realities could exist in higher dimensions. However, there is currently no empirical evidence to support this idea.

5. How does understanding higher dimensions impact our daily lives?

While the concept of higher dimensions may seem abstract and distant from our daily lives, it has practical applications in fields such as physics, engineering, and computer science. Understanding higher dimensions can also challenge our perception of reality and expand our understanding of the universe.
