The coin coming up heads 100 times in a row is literally impossible. You could flip the same coin nonstop for a billion years and it would never come up heads 100 times in a row.
The odds of flipping heads once is 1 in 2. Odds of flipping heads twice in a row is 1 in 4. Three in a row is 1 in 8, and four in a row is 1 in 16.
That means that, on average, you would have to flip a coin 16 times before you start a streak of 4 heads in a row. Of course it might start on the first flip, or it might start on the 100th flip. But again, on average, it'll take 16 flips before you start a streak of 4 heads.
So you just take 2 to the power of however many heads you want to get in a row, and there is the odds. If you want 5 in a row, it's 1 in 32. Ten in a row? That's 1024 flips on average to start a 10 head streak. Go ahead and try it, I'll wait.
At this point the odds quickly get out of hand, and we still have to get 90 more heads in a row. It's going to take a while, so I'll just say it takes 1 second to flip a coin, and I'll start giving the odds in years. I'll just round a year off to 32 million seconds, or coin flips.
If you want 30 heads in a row, it'll take you about 33 and a half years.
If you want 40 in a row, it'll take about 34,000 years.
50? 35 million years.
60? We're at 36 Billion years already.
To get 70 heads in a row, it'll take 37 Trillion years.
We are already beyond the realm of possibility, so I'll just skip to 100 heads.
40,000,000,000,000,000,000,000 years.
But, again, that is on average. If everyone in the world started flipping coins right now, once per second, nonstop 24/7, somebody might get lucky and start a 100 head streak in the next 5.6 Trillion years.

The idea that time actually slows down as your velocity increases. If you could fly fast enough, time would essentially stop. Basically, if you could travel fast enough, you could travel to anywhere in the universe wile no time elapses.
I got really pissed off when I initially learned of this phenomenon
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.

Space, distant galaxies/universes.
I get nervous and sweaty palms when I realize just how small we are in comparison to the other planets and galaxies.
My irrational belief is a stray meteor will come and hit Earth, knocking it out of orbit and killing us all.
Also I get this crazy gut sinking feeling when I imagine myself falling out of gravity and just floating into space. The entire deal trips me out.

How big the Universe truly is
Eternal life possibility
God..and if God is exist why create such a falty product like us?
Why anyone thinks Mumble rap is good music

So you're saying that there is a chance.
Light as both particle and wave is one that I can't begin to grasp.
The fact that observing an experiment changes the outcome - that's just incredibly weird.
Dark matter too - but physicists don't get that one either.

An even harder concept is that the universe is finite but has no end and that there is nothing, not even space, that is not contained within the universe.

I agree with you it seems paradoxical because for example, the odds of flipping a coin 5 times and getting 5 heads is 3%. So if you made the bet from the start that there wouldn't be 5 heads in a row you would think you've got pretty good odds.
But each time the coin is flipped and beats the streak odds, the odds improve for the completion of the steak, such that when you arrive to the last 5th toss it's become a 50/50 proposition to complete the steak.
