Re: NASA:- Important NASA News Briefing
Remember all the wild speculation about this one: http://asterisk.apod.com/viewtopic.php?f=31&t=22146 Yes bystander, I remember it all too clearly. I will admit you are right, I will be more circumspect when reporting similar news in the future. However, a little part of me, cannot help but be ...

Re: Light and Gravitational Fields
If we consider a pair of photons racing together, then no, because the gravitational field of each photon itself only propagates at c, so the photons are causally disconnected from each other. It's kind of like a couple of speedboats racing along, leaving wakes. The wakes interact behind the boats,...

Light and Gravitational Fields
Hello everyone, A question on Light and gravitational fields, I was engaging in friendly banter with an engineer friend of mine, and he proceeded to ask me, quite out of the blue, if light has its own gravitational field. Initially, the question appeared to be rather strange, and I had not quite con...

Re: Fireball48 Alert: Fireball Over the United Kingdom
What I was doing was entering the search term "meteor' and/or "fireball" and then selecting only videos that had been uploaded "This week". This technique still fails to find the video you linked to. So please tell us how you found it! - RJN RJN, I almost do the same exact ...

Re: Fireball48 Alert: Fireball Over the United Kingdom
I found a video, of a person who claims to have caught the event on the camera in his car. I am sent the Youtuber an email, requesting him in very kind words, if he could divulge his location when he caught this :-

Re: Fireball48 Alert: Fireball Over the United Kingdom
On a UFO hunters website, I found a couple of people discussing a streak of light and a fireball explosion that they apparently thought was a firecracker. However, one of them uploaded a google maps image showing the direction of the apparent streak, Here is the Image :- http://files.abovetopsecret....

Re: Fireball48 Alert: Fireball Over the United Kingdom
I wonder if any of the pseudo-scientific UFO watchers caught any images, I am guessing they might have cameras pointed permanently to the skies. I have been looking through a large number of mainstream news reports, for a couple of hours now but no one seems to have a photo or video of the event yet.
