The human brain has more synapses than the Milky Way has stars

It doesn’t take much to realize that science is awesome! For example, you probably already know that everything is made up of atoms. Those atoms have a few protons and neutrons in the nucleus and then they are surrounded by electrons that orbit the nucleus like little moons (simplified explanation). At any rate, the most interesting thing about atoms is that they are about 99.99% empty space. That’s right. This screen consists of atoms. And those atoms consists of almost nothing. So why is it that you don’t see right through the screen. In fact, how is it that we can see/feel/stand on anything at all? It’s because of forces. Those atoms in the table (in spite of just being mostly empty space) actually repel the atoms (aka empty space) in your hand. So what you are touching isn’t actually a “thing”. When you touch something you are actually experiencing a repulsive force, kind of like gravity. And since those empty atoms reflect photons, you cannot see through them. You only see the photons being reflected off of what is essentially empty space. Crazy right?!

See we told you science was awesome! Just wait til you read about all the other scientific truths found in this list! So if you’re ready to give your brain a challenge, read on! These are 25 mind bending scientific truths to challenge your brain.

The coldest place anywhere in the known universe is (was) right here on Earth in a laboratory. Scientists managed to nearly freeze atoms using laser cooling. This has lead to temperatures within a billionth of a degree of absolute zero.

All of the cells in your body have been dividing ever since life on Earth began. And all of that division will end with your death except for any cells that you pass on to your offspring (1 per child) and a few special circumstances (organ donation, etc)

When you remember a past event, you’re not remembering the event itself, but rather the last time that you remembered it (except the first time of course). In other words you’re having a memory of a memory. This is partially why human memories are so inaccurate.
