Will black holes reach Earth?

Despite their abundance, there is no reason to panic: black holes will not devour Earth nor the Universe. It is incredibly unlikely that Earth would ever fall into a black hole. This is because, at a distance, their gravitational pull is no more compelling than a star of the same mass.

Is the sun black?

As with all matter, the sun emits a “black body spectrum” that is defined by its surface temperature. A black body spectrum is the continuum of radiation at many different wavelengths that is emitted by any body with a temperature above absolute zero.
