Any reliable sites on "alternative" news and knowledge?

The internet is quite infinite, compared to our very small-sized conception of space-time.
I’m looking for good sites that offer knowledge, news or simply incentives to general awareness of certain topics..and by good I mean: NO Bullsh*t.
The topics are various. To list a few:
-Space-Time
-Time Travel
-Relativity
-Quantum physics
-News on researches
-Astrophysics
-Unpublished/Censored “News”

and to be a bit more inquisitive on these more “off the wall” topics:
-Reptilians and their history/pseudo history (call it as you like)
-Conjurations
-Hidden Knowledge
History of the Illuminati and more details
-all the claims of David Icke and David Wilcock

..etc.. I I think of more, I’ll just post them in along with the answers.

Just so you know.. My background as an (amatorial) Esoteric researcher gives me the input to be curious and exclude nothing. Just need some trustworthy material to analyse and elaborate. Most of what I found on the net was either partial or evidently false information.
I’m looking for objective investigation.
