Scientists now know what you saw before you were born

A YouTuber has drawn on various scientific studies to figure out the experience people go through before they're born.

Some of the facts are so bizarre, they're almost unbelievable.

The YouTube video was uploaded by Vsauce - who has over 18.3 million subscribers - using source material from various scientific studies to illustrate his findings.

He captioned the video: "What did you see before you were born?"

The short clip has since received over 2.3 million views, 315k likes and over 4.8k comments.

He starts off the video saying: "Before you were born - what did you see? How dark was it inside your mother's body?"

"Pretty much no visible light gets deep within our body cavity."

"Inside a womb at night, this is what you'd see," as the video pans to a totally black screen.

"In the day, it might look more like this," he says as the screen changes to a lighter, dark brown colour.

Giving his viewers a fun fact for future dinner parties, Vsauce adds: "In fact, it can be bright enough inside a womb to read a book.

"Inside a womb, covered by light clothing and averagely-thick abdomen, in direct sunlight, it can be as bright as an overcast day or even a typical office building," he reveals.

"It's a womb with a view," he jokes.

Revealing even more shocking facts, the YouTuber goes on to show a triangle of red lights on the screen.

He states: "Also, if you shine a trio of lights at a human fetus in the womb, it won't really care. But, if you shine lights like this" - showing a second set of the red trio - "it will look at them and follow them."

Explaining the discovery, Vsauce explains: "The leading theory is that this arrangement [the first set of lights] more closely resembles a human face and that even before we're born, even before we've met anyone, we are already looking for other people."

The study Vsauce references goes on to state that 'available evidence indicates that, during the last two months of gestation, most human fetuses are potentially able to see and to orient their attention toward visual stimuli'.

It adds: "The discovery that the uterine environment is rich in auditory and olfactory stimulation revolutionized the way scientists and laypeople look at prenatal life, and revealed a previously unsuspected world of active exploration and learning by the developing fetus.

"The possibility of prenatal visual experience and learning further expands this scenario and suggests fascinating avenues for future empirical research."

Thousands of YouTube users were clearly shocked by the video and eager to share their reactions to the scientific studies.

"Giving 'humans are social animals' a whole new meaning," wrote on YouTube user.

Others found Vsauce's particular phrasing more entertaining: "'How dark was it inside your mothers body' had me laughing way harder then it should have."

One person even found the discovery 'touching', commenting: "That’s actually really touching. Introversion aside, we are all social creatures who seek human connection."
