You're right Mentz114 however, these scientist are slowing the light down after it leaves there electronic liquid crystal. Normally if light travels through, let's say, a clear glass of water. It slows down as its passing through but once it leaves it speeds back up to the normal speed of light...
That's very interesting. I'll have to look up the paper they published. I would personally like to see the experiment duplicated again and see the math but you it looks at face value like they have some result. Now to see how valid it is and of course if they were accurate in their experiment...
I've hear physicist say that if a rocket ship was shot into a black hole it would appear to slow down because of gravitational time dilation. I miss spoke about the particle observing a slower reality. It would experience
You are correct. I accept this now and have a clearer understanding of SR...
You guys are great btw! Thank you for all of your awesome answers. I'm a huge science geek. I started with astronomy and meteorology in my 20s and moved to studying physics 3 years ago. I wish I could go to school and be full time. It would be just be irresponsible to go back to school with a...
No, but if the particle at CERN was timing how long it took me to blink an eye and used that to measure its universe it would experience a slowed down timing of my blink due to its high speed. ... I understand light speed is constant. I just want to know if we are observing the correct light...
Oh and I don't think that light slows down i
Thank you, Mentz114 and Peter Donis. Great answers. So I'm getting the answer that Light does not slow down or speed up when it encounters gravity. Per Time dilation. As observed by an observer not traveling with the light. Then why does time...
My apologies Zapper Z. You teach me more than you know. I appreciate your disrespect. It is well deserved and does not offend me. I understand I am nothing, I can only hope one day to have the understanding that you've been afforded. I'm just a dumb human being on this planet curious about the...
Copied from wiki on "Shapiro Delay". Thank you MFB. Wish I would have thought of it first.
Because, according to the general theory, the speed of a light wave depends on the strength of the gravitational potential along its path, these time delays should thereby be increased by almost 2x10−4...
The title was on purpose. I wanted to get a larger group of people to view it. And get what you finally gave me. I'm familiar with lensing but I'm not with Shapiro Delay. If off to study that till the wee hours of the morning. Thank you! E
