Looking for some good websites for Physics and Cosmology

AI Thread Summary
Several users recommend websites for 8th-grade students interested in physics and cosmology, emphasizing non-technical resources. Ned Wright's cosmology FAQ is highlighted for its clarity and accessibility, while Physics Made Easy is noted for its comprehensive content, albeit with some math. Hyperphysics offers concise outlines and references, making it user-friendly for beginners. Charles Lineweaver's publications are recognized for their educational value, despite some complexity. Additionally, TalkOrigins.org provides a detailed overview of Big Bang cosmology, and YouTube is suggested as a valuable platform for diverse scientific explanations.

I've been looking for a few websites good for Cosmology and Physics, maybe you guys can help? I'm in 8thgrade, but I can comprehend a lot, just try to stay away from websites that have excessive technical math please. All posts are appreciated.
 
Space news on Phys.org
Here's a few you might find useful:

Ned Wright's Frequently asked questions about cosmology is non-technical and very well written:
http://www.astro.ucla.edu/~wright/cosmology_faq.html#CC
You might also want to navigate to his home page and explore from there.

Physics Made Easy is very good, but doesn't shy from math:

Hyperphysics provides a great mind-map with brief and to the point outlines of the subjects with references and further reading:
http://hyperphysics.phy-astr.gsu.edu/hbase/HFrame.html
(cosmology is covered in the astrophysics section)

Charles Lineweaver's publications are generally accepted as excellent pedagogical material.
This one here might be a bit daunting in places, but still very accessible:

I've found another detailed breakdown of the subject of Big Bang cosmology at TalkOrigins.org:
http://www.talkorigins.org/faqs/astronomy/bigbang.html#evidence
It's more from the "debunking the creationsts" angle, but looks scientifically accurate. Maybe somebody else can verify that.
 
Wow! Thank you, these were great.
 
Believe it or not youtube is a great place to search, just about every aspect of science is covered with multiple video's explaining the same thing using slightly different analogies.
 
Abstract The Event Horizon Telescope (EHT) has significantly advanced our ability to study black holes, achieving unprecedented spatial resolution and revealing horizon-scale structures. Notably, these observations feature a distinctive dark shadow—primarily arising from faint jet emissions—surrounded by a bright photon ring. Anticipated upgrades of the EHT promise substantial improvements in dynamic range, enabling deeper exploration of low-background regions, particularly the inner shadow...
https://en.wikipedia.org/wiki/Recombination_(cosmology) Was a matter density right after the decoupling low enough to consider the vacuum as the actual vacuum, and not the medium through which the light propagates with the speed lower than ##({\epsilon_0\mu_0})^{-1/2}##? I'm asking this in context of the calculation of the observable universe radius, where the time integral of the inverse of the scale factor is multiplied by the constant speed of light ##c##.
Title: Can something exist without a cause? If the universe has a cause, what caused that cause? Post Content: Many theories suggest that everything must have a cause, but if that's true, then what caused the first cause? Does something need a cause to exist, or is it possible for existence to be uncaused? I’m exploring this from both a scientific and philosophical perspective and would love to hear insights from physics, cosmology, and philosophy. Are there any theories that explain this?
