As soon as I saw the ripples (near end of video) moving away from the bottle instead of toward the camera, I thought it might be an effect similar to a strobe light on a fan, where the fan appears to move backwards because of the method of observing, NOT because it actually is moving backwards. What do you think, Dr. Glenn? Or is this video "proof" that time distorts as we near the speed of light?

Remember that the light that we see is simply reflected or diffracted from the object. We would not see the light beam at all if it were travelling through perfectly empty space without the object. All motions of microcosms are affected by the motions of other microcosms. Because time is motion, I suppose one could say that "time was distorted," but that would be the case at any velocity, not just velocities near the speed of light.

The Blogger / Google login status, and the ability to post comments, is sensitive to both cookie and script filters. Your readers may need to enable (stop filtering) "third party cookies", in their browser and on their computer. The effects of the newly unavoidable CAPTCHA, and the Google "One account" login, requires third party cookies, even more than before.

Third party cookies filtering, in a browser setting, is the most common solution, overall - but your readers may have to search for other filter(s) that affect their use of Blogger / Google.

Any filters are subject to update, by the creator. If the problem started a few days ago, your readers may have to look on their computers, and find out what product or accessory was updated, a few days ago.
