re: What's a concept that's hard to wrap your head around?

Yeah but aren’t there trillions upon trillions of opportunities for things to line up perfectly? Feels like that is in our favor.

1 trillion dollars.
Think of a stack of bills. Each one of those bills is a $100 bill.
The stack would be 63 miles high to be 1 trillion dollars.

Quantum Physics-something appear out of nowhere? That's wild.
The vastness of the universe.
The idea that there are other dimensions around us, right beside us, etc.

If you flipped heads 100 times in a row you have a faulty coin. It will be heads again.
Right. That's probably well into the realm of impossible with a fair coin. You can expect a run of 7 with enough flips but anything more than that becomes extremely unlikely.

Comparing the estimated 13.8 billion year age of the Universe to a 24 hour clock, our life span occurs within the last second to midnight.
The last star in the Universe will run out of fuel about 100 trillion years from now.
Time is an interesting property.

How two people can be so in love one day then the next divorcing and doing horrible things to each other.

I saw this on Cosmos. It takes light from SOME stars so long to reach earth (billions of years) that by the time that we see them in our sky, they are already burned out.

Your intuition tells you that a run of 101 heads is very unlikely. This is correct. However you have already had the highly improbable run of 100 heads. This is where your intuition fails. You’re thinking of the entire run. What’s the chance of flipping heads again if you’ve already flipped heads 100 times?
Put another way. Chance of flipping heads 100 times in a row with a fair coin is 0.5^100 = 7.88E-31. Chance of flipping heads 101 times is 0.5^101=3.94E-31. The change in probability between these two outcomes 3.94E-31/7.88E-31 =0.5, which is the odds of flipping heads in the next toss.

See if this helps you understand:
Everything is always moving at the speed of light. You, me, the earth, sun, galaxy, and light itself. Everything, speed of light.
The difference is, light moves at the speed of light through space, while we are moving at the speed of light through time. The faster you move through space, the slower you move through time.
Here's how it works:
Think of a basic X-Y axis, 2 dimensional space. The speed of light is 1 unit long, and let's point it along the X axis in the positive direction. If it's easier to understand, we will call this due East. The object is traveling at the speed of light directly East. This means it is traveling 0mph North or South, right? Now let's point our 1 unit speed of light line along the Y axis. Now our object is traveling at the speed of light directly North, and 0mph East or West.
Now let's point our 1 unit speed of light line directly Northeast. How fast are we traveling North, and how fast are we traveling East? We figure this out by taking the sine of 45 degrees, and we determine that by traveling at the speed of light directly NE, we are traveling North at 70.7% of light speed, and we are traveling East at 70.7% of light speed.
Following along?
Now let's throw the Z-axis on there and make it 3 dimensional space. Since we are moving directly NE, or 45 degrees in the X-Y plane, we are still traveling 0mph in the Z direction, right? So now let's rotate that 1 unit light speed line 45 degrees toward the Z axis, while it's still 45 degrees on the X-Y plane. Now how fast are we moving in each direction? We can just take 70.7% of 70.7% to get 50% light speed in the X and Y directions, and 70.7% light speed in the Z direction.
Still with me? Good.
Now let's throw the 4th dimension in there, time. Oh shite, we can't draw that! We can't even really imagine it. But math can handle it. We just have to realize that time is, in fact, the 4th dimension. And since X is orthogonal (at a right angle) to Y, and Y is orthogonal to Z, and Z is orthogonal to X, then we have to somehow grasp the fact that time is orthogonal to the X, Y, and Z dimensions, and they are all orthogonal to time.
So, back to everything is always moving at the speed of light, hopefully it makes more sense now that since we are moving at basically 0c, then we must be moving at 1c through time. And as we change our "trajectory" by moving at high speed through the spatial dimensions, then the speed that we are moving through time must slow down.
Wow.. amazing...

1. That there are 3.72 x 10^13 cells in the human body.
2. The sun has enough energy to shine 5 billion more years.

Each one of them is made of billions and billions of atoms. It is thought there are 10^80 protons in the whole universe. Powers of ten blow my mind.
Along those lines, a 1080p TV with 24 bit color can display on the order of 10^14,000,000 distinct images.
The last 7 or so generations of fission in an atomic bomb like Fat Man are responsible for the big boom. The first 73 are just a fireworks show. You need the full 80 to get anywhere. That's 2^80 fissions.

The line of thinking Christians use with salvation.
Will never understand the belief that people that commit unforgivable sins (any sexual or violent crime towards children/murder etc) are magically forgiven and given the same salvation as someone who has believed their entire life and not committed unforgivable sins, just by accepting Jesus as their lord and savior. I mean shouldnt there be levels or some sins that are unforgivable?
I know the concept is that all are treated equally and loved the same but thats not true considering their stance on homosexuals. Cant pick and choose equals to fit a narrative and expect people to believe it.
Full discretion, i believe in none of it but have had the discussion many ,many times and yet will never understand the logic or amount of acceptance delivered in the explanations.
