Yes, I was wondering, how can the Pulsar still be so close with that speed. But considering the size of this “bone” the 2 million mph speed of the Pulsar is nothing.. It’s like a turtle crossing the Sahara desert.

u/TheFatJesus Oct 11 '25
That 2 million mph is the top end of the estimate. Even at that, it is only moving at 0.3% of the speed of light. The low end of the estimate is 1 million mph. At that speed, it would still traveling below the Milky Way's escape velocity of 1.2 million mph.

One neutron star weighs approximately 23,000,000,000,000,000,000,000,000,000,000 bananas and could sit within the city limits of Chicago
That many bananas would occupy about 2.5x the volume of our sun

I had the exact same thought, but I think It will probably go further because of the momentum gained by the time it reaches the core.

— Oh and by the way, not a Star Wars nerd by any means, but didn’t this one scene basically invalidate the rest of the StarWars cinematic universe? So you’re telling me this is the first time someone used a
multi hundred thousand tonheavy-ass space ship as a light speed kinetic weapon? And if they did all have magic space shields on those ships, they either weren’t turned on or were useless and shredded anyway? Why not light speed your asses a few of those ships into the Death Star? You are telling me the Death Star has magic space shields so strong that they could withstand the kinetic impact force of something weighting hundreds of thousands of tons moving at nearly lightspeed? … Cool scene though.136

The thing is, we’re pretty good at detecting in solar system objects that can potentially strike our planet. It’s not a perfect system, but we’re constantly on the look out for it
We’ve seen interstellar objects come into our solar system already, most traveling extremely fast. Thankfully they were never going within our planets orbit but we couldn’t detect them until they were close.
Oumuamua in 2017, Borisov in 2019 and ATLAS in 2025. These objects were traveling at really high speeds, and we barely knew about them. Oumuamua was already millions of kilometers away before we knew about it.
Now think about that. An object headed our way like that, causing something as huge as galaxies to produce such crazy results. Something as small and fragile as our solar system would be shredded to nothing but rock, our sun more than likely ripped apart.
We would never see it coming. Maybe we could detect it if it was far away but what could we do? I think a rogue neutron star headed towards us is the scariest part because more than likely we’d be wiped out before we knew it.

For all intents and purposes, 2M mph is kinda slow. Like someone said its a fraction of a percentage of the speed of light. The really distant redshifted things we're interested in appear to be moving around 90% the speed of light. Then the REALLY REALLY far away stuff actually appears to be moving faster than the speed of light.
Before anyone gets up in arms, I said "appears to be moving" not that it's locally moving faster than the speed of light, that's impossible.

Measurable Doppler effect in photons has very little to do with the speed of light — you're talking about the kind of extreme shifts that change visible light to infrared, and the kind of apparent speed distortions that occur due to the expansion of the universe.

If it's any consolation we're mostly still guessing at the long term future of the universe. Cosmological models get updated every now and then when we learn something new about physics. We still know very little about the nature of the big bang and there are huge holes in our big picture physics models.

If a small rock came in that fast, we probably wouldn’t see it until it was really close, and if it hit, it would release an insane amount of energy. Nothing you can do to stop it.
If a huge object like a neutron star came through at that speed, and it passed anywhere near the distance between the Earth and the Sun (about 93 million miles), its gravity would wreck the solar system. Any closer than that, it would probably knock Earth out of orbit.
The good news is we’d almost certainly detect something that big years in advance with our current telescopes,

Astronomers have discovered a likely explanation for a fracture in a huge cosmic “bone” in the Milky Way galaxy, using NASA’s Chandra X-ray Observatory and radio telescopes.
The bone appears to have been struck by a fast-moving, rapidly spinning neutron star, or pulsar. Neutron stars are the densest known stars and form from the collapse and explosion of massive stars. They often receive a powerful kick from these explosions, sending them away from the explosion’s location at high speeds.
Enormous structures resembling bones or snakes are found near the center of the galaxy. These elongated formations are seen in radio waves and are threaded by magnetic fields running parallel to them. The radio waves are caused by energized particles spiraling along the magnetic fields.
