There have been some conspiracy theories circulating about it being fake, but there's no evidence to support that claim.
Here's why it's likely real:
* Architectural design: The window is a prominent feature of the studio's design, visible in numerous photos and videos. It wouldn't make sense for a network to invest in a complex and visually prominent fake window.
* Weather reflections: The window reflects the weather outside, showing changes in cloud cover and sunlight, which is consistent with a real window.
* Shadow patterns: The window casts shadows on the studio floor, again indicating it's a real opening.
It's possible that the window might have a few technical tricks for visual effects, such as adjusted lighting to create a particular mood. However, this doesn't mean the window itself is fake.
Ultimately, there's no concrete evidence to suggest that the window is anything other than a real window.
