By comparison the moon spins 27 times slower than Earth and has 1/4 its radius. Roughly ac=v2/r so the Earth’s centripetal acceleration is 27v2/4r gre...

If Earth’s rotation doubled in speed where we had two mini-nights a day, would that have any physical effect besides sunlight hours? If the Earth stop...

We don’t see the full extent of the orientation of the Earth’s plane we’re rotating in unison with. We can only see as far as the horizon. The Earth’s...

Randomness can be inferred when the process that caused it is unknowable, infinitely complicated and hence unpredictable or else if it was caused by s...

It’s like the entire sequence is unreal even from the very beginning rather than towards the later infinite part at the other side.

An interesting feature of the -1/12 result is that it’s legible which is surprising given the infinite number of possibilities. For instance it’s not ...

We can’t make perfectly random sequences with chaotic mathematical equations and therefore random number generators have a spectrum of unpredictabilit...

Perhaps the equations have their own sense of humour! Not technically random but capricious and whimsical!

I’m not a mathematician but I remember reading that all of the infinite number of natural numbers add up to -1/12. Maybe there will be a counterintuit...

Science often conveniently approximates the world as physical seeing as physical objects are by definition impersonal and objective. Historically scie...

Our voice in our head can sometimes be guided by subvocalising and so our motor system is in sync with our consciousness.

If we had the capacity to mentally time travel forward then we could skip the disordered states of dreams and only remember our organised conscious th...

Can there be two Boltzmann brains?! If I’m a Boltzmann brain then so are you! We’d be in a universe of interacting brains! https://m.youtube.com/watch...

If we were somehow conscious during a saccade then we’d be momentarily cross-eyed.

Saccades are involved in moving our small central vision to look at objects. If the image we see is 2D then the micro-parallax of saccades could help ...

Parallax can be inferred from horizontal eye positions and also slanted or vertical eye positions when you rotate your head. There’s a plethora of par...

Our eyes must be completely numb so as not to wake us up during REM sleep.

The brain moves relative to others but not relative to ourselves!

The body moves but the brain is always in the same location in the body. Moreover the skull protects it from accelerating.

If the mind is separate from the body under dualism then it wouldn’t have to move.

There’s little relative motion between our brain and our eyes, head or body. Your eyes are always a certain distance away from the visual cortex. So i...

Instead of asking where’s our consciousness perhaps we need to first check where is our brain!

https://www.psypost.org/wp-content/uploads/2015/07/Eye-and-brain-by-Fotolia.jpg We tend to think the brain is behind where we feel our eyes to be. Alt...

Electromagnetism is stronger than gravity over short distances. So forces like friction between our feet and the ground means we don’t fully experienc...

The sense of touch is inside the brain so when you feel the back of your head that’s actually a lot closer to your visual screen than it appears. The ...

If the mental sphere took up space then it would create a double occupancy problem with physical space unless it were always a millisecond ahead or be...

If the visual world were 2D then it’d be like our mind teleports forward whenever we walk around. In this example the mind would be stationary in the ...

In a dream we often have a semblance of a body even though we often don’t take any notice it. So if you were swimming in a dream then maybe you’re rig...

Remember our volitional muscles are always partially active through muscle tone. Maybe when we are choosing which arm to move, one of them will automa...

I watched a YouTube philosophy video that mentions a “frustrator”. It’s about trying to predict whether someone will press one of two buttons when the...

Perfect circles don’t exist in nature and pi has an infinite number of digits. So when you rotate around and move forward in a certain direction, we d...

The mind is more arbitrary and whimsical in nature than the physical structures we observe. What would a random universe look like? For starters we ca...

Besides even if we could artificially simulate our senses you’d still have to instantaneously rewire the brain with electrodes to prevent a deadly gap...

I believe an anti-realist can also be pragmatic. Our power is limited in this world whether it’s real or not. The subconscious mind has involuntary pa...

One more criterion for comparing anti-realism to materialism is the phenomena it might predict. We all know the amazing mathematical predictions from ...

One could say that the curved retina demagnifies the object to create perspective. This would be instead of the expanding sphere of decreasing light i...

We use perspective to infer distance. That distance is the extent of empty space between you and the object. Therefore we can use perspective to infer...

One metric that language fails to immaculately communicate is intensity. Let’s take a negative emotion like fear. We can say that an event was mildly ...

What I was getting at is that there might be a non-real or spiritual aspect to emotions. It’s like our language allows us to express 90% of those emot...

Is our sensation of anger or happiness the same as other people’s? There’s certainly some overlap because we can distinguish between positive and nega...
