Any idea what this alien megastructure is? They keep making shit up but really what could it be?
 
They pointed telescopes there atm. They need more observation time to find out. Perhaps it's just a debris of comets/asteroids dimming that star. Alien megastructure explanation is ugh ... but I dunno anything is possible.
 
I really hope it is aliens but maybe we are better off alone lol but I know there's something out there may not be advance alien life but some kind of reptile looking things is my guess
 
Yeah, everyone is secretly hoping that it's aliens. Just like with those mysterious fast radio bursts. It's natural to think that we are not alone in the entire Universe.
I think that alien life forms look nothing like terrestrial life forms. I think it's something extremely exotic and unimaginable, maybe even not carbon based life.
 
Yea I'm sure we find something here soon hopefully
 
I'm convinced that there are other lifeforms in our galaxy alone and certainly there must be in the entire Universe but there is no proof as yet. Possibly they already know about us but have quarantined our solar system because of our nature. It would probably be a bad thing for us if aliens did make contact with us since peaceful beings would avoid us for now. Sorry for the pessimism but look around the world and at our history.
 
The truth might already be out there we just don't know it yet the things our governments can hide you just never know.
 
I wonder-ponder on the universe's expansion being within itself ,more or less the size before "Big Bang".
 
Great question. If Big Bang is not the "beginning", there was vacuum which fluctuated and spawned the Big Bang. Then metastable sector of spacetime within that "hot soup" fluctuated and initiated Inflation (expansion). And so on. Basically Universes get created over and over again as one vacuum state jumps from one state into another. That's cyclic (oscillating) model aka inflationary cosmology. No beginning, no end, just endless cycle.

There are other models too which don't accept inflation.

Atm It's not possible to say who's wrong and who's right so standard model just says "ok let's accept Big Bang as "beginning" (not creation)". Without proper quantum gravity theory it won't be possible to answer these questions.

Astronomers have used Hubble to make an incredible discovery — they have observed the most distant star ever seen.
