Eventually, the observer gets close to the horizon. What does he see then? Do the piled up ships start suddenly slipping through the horizon?

We could also use the radar, but that&#39;s not the same as looking. So here is the definition that supports my point of view:<br/><br/>The ship in front of me keeps transmitting its coordinates (faster and faster and using shorter and shorter wavelengths to adjust for the redshift I&#39;m perceiving). With this definition, I will &#34;see it&#34; stalling in front of the horizon. If there are multiple ships, I will &#34;see&#34; them squeezed in front of the horizon.

This is consistent with the perception that the horizon has been moving towards me with the speed of light ever since the first ship hit it. But has it? I only started my free fall recently. Before then I was hovering at a constant distance using my engines. <br/><br/>Even worse, imagine that the line of starships is 100 light years long and it takes me 200 years to reach the black hole.

I think, for a very large black hole, the dust lines would be practically vertical. Is that right? 2024-11-24T13:43:03Z https://yabu.me/nevent1qqs2mgeplgzn4t87t2q6yedtcxxsv8xc7ewerwapux50cauv6s2m82czypraq6deyfcc9j28lf5hfsed0n0cwe84j9h0pekcsqghyzev78d4xm8se3w In reply to <a href='/nevent1qqszuvpl29pp4fkjhvmq4vdj8thsvhxl6zpk02sl0p4ferec0jsacrqwyrpu5'>nevent1q…rpu5</a><br/>_________________________<br/><br/>So you see my confusion: If the approaching horizon looks like a black wall, you shouldn&#39;t be able to see your hand that has just crossed it. 2024-11-22T09:54:37Z https://yabu.me/nevent1qqsx486wddlzuxlafaqxhzmcl9hq6mrz7v69jfh5h77767nldl2n6xqzypraq6deyfcc9j28lf5hfsed0n0cwe84j9h0pekcsqghyzev78d4xhpdaq2 In reply to <a href='/nevent1qqspejjsrhs4ts454hdj7jy4dg86z3m59napezjlwpt0y09akecjq5c6pxe4l'>nevent1q…xe4l</a><br/>_________________________<br/><br/>If my hand doesn&#39;t disappear, it means I can see things in front of me, including the singularity?

Surely you&#39;d see the horizon as a black surface coming at you, since no light can escape the black hole. And once your legs get past the horizon, you&#39;d lose the feeling in them forever. Although the math inside a black hole gets really crazy, so I don&#39;t know how much I can trust my intuitions. 2024-11-21T18:23:20Z
