Here is some science that may concern you

Here is the background:

https://en.wikipedia.org/wiki/Quasar

So what is the problem concern?

The concern is that Science knows that there is an AGN that is at this moment quiescent. If also faces us.

If it would be activated, the argument is that that electromagnetic beam will come to us and earth will be a burnt crisp.

Very few people know about this. 

Is it better to live in the bliss of ignorance or to have the knowledge of what might be our shared common fate.

Of course there is a chance that in that time to come, we may be able to build a mirror to deflect the beam.
