Cal Tech Jet Propulsion Laboratory says:
The need to understand the planet we call home has never been greater. As the population of our pale blue dot continues to grow, humans and all living things vie for an ever-shrinking pool of natural resources. Fresh water. Clean air. Food. Habitable land. As Earth's climate changes in response to human and natural causes, these resources are strained.
NASA's contingent of dedicated Earth scientists and engineers -- the world's largest -- together with its armada of Earth satellites and airborne instruments, study all aspects of the Earth system--its ocean, atmosphere, ice, land and biosphere. Together, this conflux of humans and machines is advancing our scientific understanding of our ever-changing Earth system, helping to meet the needs of society.

JPL studies help us identify how Earth's climate is changing, understand the causes of these changes, and support development of models used to predict future global change. Currently, JPL has six dedicated Earth science spacecraft in orbit, with another five instruments flying aboard NASA's Terra, Aqua and Aura spacecraft. Several more missions are planned for launch in the next few years. Decision makers around the world use JPL Earth science data to support policy-making and resource management decisions.

Asteroid 2011AG5 could strike Earth in 2040
Makes being 10 pounds overweight seem like small potatoes, doesn't it?
If you didn't want to view the above mentioned video you can check out the following from NASA and the Cal-Tech Jet Propulsion Laboratory
Here is their Asteroid 2011AG5 orbit calculations
Looks as if it might come a bit close to Earth . . . right?_____
I found a word I didn't know the
meaning of so I looked it up . . .
Higgs boson
The Higgs boson is a hypothetical elementary particle predicted by the Standard Model (SM) of particle physics. The Higgs field is a quantum field with a non-zero value that fills all of space, and explains why fundamental particles such as quarks and electrons have mass. The Higgs boson is an excitation of the Higgs field above its ground state.
I looked it up, but still
do not know what it is.

Here is an understandable science analogy:
The chess-board is the world; the pieces are the phenomena of the universe; the rules of the game are what we call the laws of Nature. The player on the other side is hidden from us. We know that his play is always fair, and patient. But also we know, to our cost, that he never overlooks a mistake, or makes the smallest allowance for ignorance.
The above is reportedly a quote by . .

Penetrating so many secrets, we cease to believe in the unknowable.
But there it sits nevertheless, calmly licking its chops.
