They can be. Stars are very hot and can emit harmful amounts of radiation. At the same time, without stars there would be no life.
Life would be horrible. People would go their appointment on the right day but what time?
Life would be quite boring, now we can let our imagination fly.
Massive Stars.

They can be. Stars are very hot and can emit harmful amounts of radiation. At the same time, without stars there would be no life.
Without gravity there would be no stellar nebulae. Without stellar nebulae there would be no stars or sun, nor earth. Consequently there would be no life.
Without gravity, it is doubtful that the universe as we know it would exist at all. At the very least, galaxies, stars and planets would be unable to form. Worse still, without stars there would be no heavy elements and it is unlikely that life would exist.
Without stars, there would be nothing but a cloud of hydrogen and helium gas. There would be no planets, no carbon and thus no life - eg you and me. There wouldn't be a computer to ask this question. We are all made out of star stuff.Life of course would be very difficult. The stars have helped people in the past with navigation and telling time. also the stars have helped to create calendars both in the past and for the present.
life without ukulele would be dissapointing
Without energy, there would be no life.Without energy, there would be no life.Without energy, there would be no life.Without energy, there would be no life.
Without an early presence of black holes, it is impossible for galaxies to have formed. No galaxies, no heavy elements near Main Sequence Stars. No such elements near stable stars, no rocky planets that have the time to develop life. No life, no observers. So, black holes are "fundamental" in the sense that a Universe without them would be a Universe without anyone to recognize that there were no black holes!
No - without gravity, galaxies would not have formed, planets would not have formed, stars would not have formed.
Life would stink.
There would be no life.
we couldn't track the moon, stars ,the sun ,or little children
There would be no life because without the geometry of the water molecule, there would be no water. No water, no life.
