Unsolved Mysteries of Science: What You Didn't Learn in School

Explore five unsolved scientific mysteries, from the origins of life to brainless slime that outsmarts us. Discover the Mpemba Effect, the arrow of time, and the unified force theory!

"time clearly flowing at a constant rate in a specific direction" said no one with ADHD ever

Today, I learned that slime is smarter than some people.😂

Is anyone else simultaneously impressed and terrified by slime mold?

I think it's a mistake to think of time as 'flowing'. It simply 'is'. We live in 'right now' and that never changes. All notions of 'flow', such as seconds, minutes, hours are simply perceptual constructs based on our inability to transcend time. These constructs are crucial to modern life of course. But to speak of time 'flowing' betrays our inability to understand what time IS.

There is NO way science can be certain that the abiogenesis that led to our line of creatures was the first one on our planet. It could have happened multiple times before and fizzled out before the "successful" attempt, and we'd have VERY little chance of knowing.

The slime mold treatise is by far, the most fascinating in this set!

I'm going to think twice the next time I'm tempted to call someone a slime ball⚛

The problem with Panspermia is that it just kicks the can down the road. At some point in the past at some location life originated. It originating somewhere else and traveling across the galaxy to Earth just adds more steps. There’s no reason to think that is more likely. In fact it seems less likely.

This may have already been said in these comments but I’m not going to look because YouTube does not care enough to make that efficient, so I can’t be bothered.

I was always impressed by the power of analog computers since I started playing with them back in 1971 while attending a National Science Foundation seminar (I was in high school at the time). Hilarious that slime molds can solve Japan's transit system layout in rapid order. We need slime molds planning out the SEPTA routes here in Philadelphia & its suburbs, then we can fire the big wigs running PennDOT.

For the Mpemba effect, I imagine it's akin to the same reason warm air flowing through a swamp cooler is more efficient than cooler air. There's more energy in the warmer air to be transferred to the cooler water in the substrate, thus cooling the warmer air faster.

Most interesting in my opinion atm, is trying to understand dark matter and dark energy for several reasons:
Cosmology: They are integral to our models of the universe’s formation, structure, and future.
Physics: They could reveal new physics beyond the Standard Model, shedding light on fundamental questions about particles and forces.
Philosophy: Uncovering their nature touches on deep questions about the universe and our place in it.
These mysteries drive much of modern research in cosmology and particle physics, making them among the most fascinating and profound enigmas in science.

What's up my slime? (Bio-genetically ingenius cellularly-distributed intelligence organism)

For the evolution of my sanity, will you PLEASE close that F’ing door!

props to the 13 year old scientist that titled his official paper "Cool?"

#2 Mpemba effect - generally explained by a combination of evaporative cooling was my understanding and loss of heat capacity due to the mass of liquid lost during boiling

[LiveFreeOrDieA]

I would have been a lot more engaged in math class if my teacher looked like this one @0:19

#1 Will your dad ever come home again from the milk store?


Mines didnt :(

If you place 10 bottles of water 5 at room temperature and 5 at 90 degrees into a cooler, fill it with Ice, then room temperature water, then rock salt. The hot ones will freeze faster, but the cooler ones are more prone to flash freeze when opened or sometimes just moved..

1:26 no, we don’t know that it happened exactly once. We know when it last emerged. It’s possible that life emerged and was sterilized prior to that. We just don’t know (yet).
