The cosmological constant is one of the more mind blowing values in science.
If we took a ruler the length of the observable universe and mapped some of the main constants along it; gravity, speed of light, weak nuclear force etc. We could move the value of those constants along the ruler by millions of miles to a new value - and the forces still more or less act the same way and nothing is changed in reality.
But if we moved the cosmological constants pointer even one inch along that ruler to a new value; the universe as we know it would cease to exist. It has 120 zeros after the decimal point, and then a two.
