I didn’t read every post. The grandkids are the difference in your normal routine, right? Is it possible that your glasses got broken in the pillow party, or perhaps they were taken and played with, and as a result got damaged? As a kiddo, if I damaged something that was hard to explain...

Seems very logical, but if the direction of relativistic travel can cause events on the sun in front of the ship to appear to unfold sooner and more rapidly, to the astronauts, then what would the affect be viewing events to the sides and rear of the ship?

Although I purchased a copy of Relativity on 6/1/24, I didn’t start reading it in earnest until last evening. In the first handful of chapters, notating in the margin as I read, my biggest question or open thought so far would be on the deference that is forming to the absolute speed of light...

Actually, I can feel the infrared glow of incoming fire love missives even before the “post reply” button gets hit. AE was a really likable, humble man. I’m that far in.

We will be talking.

I’ll come back. Client stuff.

To your last paragraph, the only logical answer is that the particular “speed” is what is invariant, not what speed light goes, in my opinion. Particularly, again my opinion, it’s that speed which represents 100% of that which is attainable, and it happens to be that electromagnetic radiation...

The missile is introduced only to illustrate a certain contrast. Neither your ship nor the missile can attain light speed but are not prevented from traveling just under it. The purpose of the missile is simply to relate that an object ever-so-close to the speed C, can be in your view...

If there are only three things in the universe, your ship, the missile and the laser, from slowest to fastest, whether you are going 1 mph and the missile 2 and the laser C, or you are two iotas under C, the missile is one, and the laser passes both at C, looking at the laser, you are going to...

Somehow the original, ship, missile, laser hypothetical image blended. The ships were recasting the same scenario in different terms. Some of my references to the “speed of light” or maybe light speed are not to light, but to that specific speed. I agree, completely that the final step up in...

Right, a ship cannot. The three objects in question were my ship, a missile and the laser. Laser = C; missile = just under C; ship = just under laser.

Apart from the illustrations, - and perhaps this is too sensitive to the core of SR to even acknowledge - but only C (a very specific speed) is claimed to be observed as constant in all reference frames. Take away one iota from light speed, the smallest conceivable change, and now that new...

The “it” going by me was light. And probably 4 people said that, before me. So… If you’re referring to the cruise ships, man, is that not obviously an analogy?

If it’s not striking, then it’s possible that the point blended with everything else. Envision, we’ve left port with sister cruise line ships that are so close to our speed we never lose sight of them, right? If I’m being overtaken in the lead at such a slow rate from the Yucatán, that only by...
