Proxima Centauri is 4.2 light years away. That is 24,673,274,438,400 miles. Going at the speed of the Sun through the Milky Way, 492,150 miles per hour, it would take 5,723 years to get there. In 100 years the Sun has only gone 431,123,400,000 miles, or 7 percent of 1 light year...
I know the blue whale is the largest known animal to have existed on Earth, but can animals conceivably grow larger, or is that pretty much the largest animal you can expect to find in the universe?
How do I factor monomials, binomials, trinomials and quadratic equations?
Here are some more examples from the book.
24x^3y^2-20x^2y^2+16xy^2
x^2+5x+6
3y^2+8y+4
I'm in desperate need of help with factoring. Basically, how do you do it?
Below is an example of what I'm up against.
54c^2d^5e^3; 81d^3e^2
It wants me to find the greatest common factor.

That is the book I'm working out of.
According to Wikipedia, there could be as many as 11 billion planets in the habitable zone of sun-like stars, with the closest potentially 12 light years away. That number goes up to 40 billion if you include red dwarfs. How would we even go about getting to the nearest Exoearth?
The best theories have the universe arising from a singularity 13.8 billion years ago, and have it expanding, becoming increasingly dilute and frigid for eternity. Do you think the Copernican principle holds for the universe and that we inhabit a small part of a vaster cosmos permanently beyond...
I finished Rees' Before the Beginning and am now reading The Shadows of Creation. At what point should I get out of the popular books and into text books?
