Approximately 4.6 billion years ago, the solar system was a cloud of dust and gas known as a solar nebula. Gravity collapsed the material in on itself as it began to spin, forming the sun in the center of the nebula. Small particles drew together, bound by the force of gravity, into larger particles.

• step one(4) -The solar nebula consisted of. -hydrogen,
• step two(2) -A disturbance.
• step three(2) -The solar nebula assumed a flat, disk shape.
• step four(2) -Inner planets began to form from metallic.
• step five(2) -Larger outer planets began forming from fragments.

4.6 billion years. Why did the solar nebula flatten into a disk? The force of gravity from the planets pulled the material downward into a flat disk. It flattened as a natural consequence of collisions between particles in the spinning nebula, changing random motions into more orderly ones.

By studying several things, mostly meteorites, and using radioactive dating techniques, specifically looking at daughter isotopes, scientists have determined that the Solar System is 4.6 billion years old. That age can be extended to most of the objects and material in the Solar System.

But how long to get to one trillion? A trillion is a thousand billion. So you’d need to be counting for 31.7 thousand years! To count one trillion dollars, one dollar per second, would take 31,688 years!

Googol. It is a large number, unimaginably large. It is easy to write in exponential format: 10100, an extremely compact method, to easily represent the largest numbers (and also the smallest numbers).

Prof Hugh Woodin, University of California, USA – “One of the largest numbers we have a name for is a googol, and it’s one followed by a hundred zeroes. A hundred zeroes is a lot because each zero represents another factor of 10.”

Despite having more numbers than atoms in the universe, trying to prove that your integer is bigger than anyone else’s integer has continued through the centuries. The biggest number referred to regularly is a googolplex (10googol), which works out as 1010^100.

ABSOLUTE INFINITY !!! This is the smallest ordinal number after “omega”. Informally we can think of this as infinity plus one.

No. They’re all the same. No because infinity doesn’t have a numerical value, it’s a concept of something that never ends and it doesn’t follow the rules for our numbers that we’ve created.

In the affinely extended real number system (which is a mouthful meaning “the real numbers, and negative infinity, and positive infinity”), absolutely: positive infinity is the highest number. In other number systems, we’re not so lucky.

There are whole sets of numbers that have been conceived of that are as mind-bendingly larger than Graham’s Number as Graham’s Number is itself large. Obviously, even Rayo’s Number is not in any sense “the largest number”. There is no such thing. We can always add one to any number and get one slightly larger.
