Of course this is all dependent on the mass of the object. There are meteor showers pretty often and so far, I am able to go out and mow the lawn without a pressure suit. People tend to forget that an explosion sends debris across a 360 field and certain dynamics would surely send most of it back into space.
Depending on how close it is. If it's too close to earth, much of it would be captured by earth's gravity.

Btw, Carl Sagan's Pale Blue Dot ftw. Cosmos always managed to humble me.

Pardon my ignorance but would the fragments burning up in the atmosphere really combust that much oxygen? I've been searching online for something explaining this but everything I find only makes the shotgun analogy but doesn't explain in depth how it would be worse.

Destruction concentrates on rendering the impactor harmless by fragmenting it and scattering the fragments so that they miss the Earth or burn up in the atmosphere. This does not always solve the problem, as sufficient amounts of material hitting the Earth at high speed can be devastating even if they are not collected together in a single body. The amount of energy released by a single large collision or many small collisions is essentially the same, given the physics of kinetic and potential energy. If a large amount of energy is transmitted, it could heat the surface of the planet to an uninhabitable temperature.

Indeed because the universe is infinite and vast thus numbers, time, space does not exist.

Makes one wonder.

I don't see how the conclusion follows from the premises.

Certainly by scale anyhow.

The only way to deactivate the ray beam and fight back the vampire alien threat is with a complicated series of foot patterns on the device's control board that looks remarkably like a DDR pad. We will all praise this man for saving our lives and buy him a mountain of stuffed animals.
