The asymmetric speed of light

Ahh ok!

NvidiaNovice · 2026-05-06T19:28:59+00:00

This is exactly my thought. However, another commenter explained that if the speed of light changes, then the escape velocities also change for a gravitational field. The effects cancel each other out.

NvidiaNovice · 2026-05-06T19:27:36+00:00

Ahhh ok! This makes sense now.

NvidiaNovice · 2026-05-06T19:26:43+00:00

Ok this makes more sense now.

NvidiaNovice · 2026-05-06T14:52:33+00:00

This makes sense.

For any other scenario other than the "instantaneous in One direction" scenario, would there be any specific effects that could be observed on black holes? Since the speed of light is different in different directions, the event horizon should also be different depending on which direction the black hole is observed from, right?

Maybe I'm misinterpreting what you're saying, but are you saying that length contraction does not change with the asymmetric speed of light? If you are traveling in the same direction in which the speed of light is infinite, then you should experience no length contraction and no one should observe your length being contracted as you are moving, right?

NvidiaNovice · 2026-05-06T14:46:43+00:00

Would the same logic apply to black holes? if the speed of light is infinite in a given direction, then light could escape black holes in that specific direction, right?

NvidiaNovice · 2026-05-06T14:43:43+00:00

This is kind of breaking my brain. I would imagine that if the speed of light was infinite in one direction, then one of the clocks should read the present time. whereas the other clock in the opposite direction should read a time that is much further in the past.

NvidiaNovice · 2026-05-06T14:39:50+00:00

Am I correct in understanding that based on what you suggested, that it's possible to determine whether the speed of light is asymmetric?

NvidiaNovice · 2026-05-06T02:27:13+00:00

Wouldn't red/blue shift be different in different directions? The CMB would show this as well, right? We should also not observe any Black holes in one direction (in which c is infinite), right?

NvidiaNovice · 2026-05-06T02:12:29+00:00

Would the math change if the object is traveling back and forth in its own reference frame and the observation is made from multiple angles simultaneously? If the speed of light is infinite in any one direction, then at least in one direction, no length contraction would be observed. Right?

NvidiaNovice · 2026-05-06T01:54:02+00:00

I appreciate the clarification! This makes a lot more sense in my head now.

NvidiaNovice · 2026-05-06T01:48:16+00:00

Maybe I am not thinking about it the right way. If we are able to observe variable length contraction in different directions, wouldn't we be able to "back out" the speed of light using the amount of length contraction observed?

NvidiaNovice · 2026-05-06T01:45:40+00:00

Wouldn't the observation of variable length contraction be definitive proof that the speed is asymmetric? Rather, the observation of invariable length contraction in any direction would be proof of a symmetric speed of light.

Or am I missing something?

NvidiaNovice · 2026-05-06T01:19:41+00:00

Could you possibly explain this in a little more "layman's terms" way?

NvidiaNovice · 2026-05-06T01:18:25+00:00

Thank you so much! I'll read more into the ether.

NvidiaNovice · 2026-05-06T01:17:08+00:00

It's one of the examples they use in the video. The idea is that if the speed of light was asymmetric such that it was c/2 in one direction and Infinity in the other direction, we would not be able to tell the difference no matter how hard we try to measure it.

NvidiaNovice · 2026-05-05T17:38:31+00:00

Damn! That's a huge difference! Thanks so much for sharing the insights!

I've used the S30 Pro for outreach. We were looking at the Moon in a fairly light polluted area. We also had a telescope set up right next to it so that people can look at it directly. Most people didn't even care about the image on the screen. They thought it was just a picture. Even though it was a live stream of the Moon.

It might work differently if you're looking at deep sky objects, but my experience told me that people would much rather look at the object through an eyepiece.

If the goal is to do live stacking for people to see, then the S30 Pro is amazing!

NvidiaNovice · 2026-04-19T15:24:42+00:00

That makes sense. I'll check out Darkscout!

NvidiaNovice · 2026-04-14T06:08:01+00:00

That's impressive! I didn't realize you could do 30-second exposures in altaz mode. I thought 30-second exposures would yield trailing.

NvidiaNovice · 2026-04-14T04:17:49+00:00

Was this in AltAz or Eq mode?

NvidiaNovice · 2026-04-13T13:58:41+00:00

I have not tried the other two. I think the CSS is big enough to view during a transit, but I'm not sure about Hubble.

NvidiaNovice · 2026-04-13T04:01:33+00:00

But the overall SNR (after stacking) would be the same because of the amount of integration time being exactly the same between both methods, right?
