About this website
This website is operated by Cosmoknowledge LLC, Houston, Texas, United States. These terms cover our website, educational content and browser simulations. Contact us at [email protected] with questions about the website.
Explore responsibly
You are welcome to browse and use the interactive experiences for learning and personal enjoyment. Please do not interfere with the service, attempt unauthorized access, misuse forms or infringe other people's rights.
Our explanations and simulations are educational. Models use assumptions and approximations described in the relevant experience. Results are not a substitute for professional engineering, safety or other advice, and should not be used to make real-world emergency decisions.
Content and artwork
Cosmoknowledge's original artwork, branding and content belong to Cosmoknowledge or their respective rights holders. You may share links to our pages. Reusing artwork or content for commercial purposes requires permission unless a separate license or applicable law allows it. Third-party material remains subject to its owner's rights and any stated license.
Merch purchases
Fourthwall is the seller and merchant of record for products purchased through the connected Fourthwall checkout. Fourthwall handles payment, fulfillment and order-related enquiries through its services and production partners. Its purchase terms and applicable policies govern those transactions. Fourthwall is not a party to these website terms.
Before paying, review your selected product, size, quantity, delivery address and the total shown at checkout. Shipping is separate from the displayed product price. Taxes, currency conversion, duties and delivery availability depend on the order and destination. Product previews illustrate the design; screen colors and printed colors can differ.
For order, delivery, damage or print-quality enquiries, use Fourthwall's shop support form and include your order number. The shop's return policies and your applicable consumer rights govern any refund, replacement, cancellation or withdrawal. Nothing in these website terms limits rights that cannot lawfully be excluded.
Adding items to your bag creates no purchase. An order requires completing payment through Fourthwall checkout. YouTube channel memberships are a separate YouTube service, governed by the terms and benefits shown there.
Newsletter and external services
The Cosmic Dispatch is an optional newsletter. Confirm your subscription to receive it and use the unsubscribe link to stop future issues. Our privacy notice explains how information is processed. External sites and services, including video players, have their own terms and policies.
Updates and availability
We may update content, simulations and these terms as the website develops. The date above identifies the latest version. Features may occasionally be unavailable or contain errors. If you spot a problem, please contact us so we can review it.
