I remember Dr. Jill Tarter speculate that although pulsars are natural objects a few of them could have artificial origin.

It could be just a regular pulsar after a collision with another object that changed its spin, right?

👩🏻‍🦰: _”…this Axis of Evil_ _is aligned with our_ _solar system!”_ Sounds like the Justice League has really got its work cut out.

A wondering: neutron stars and magnetars are remnants of shortlived supergiants, burning out in just some million years. This means that these remnants, around 15-100 times heavier than the Sun, should be extremely abundant in the universe and keep quite a lot of the original mass. Since these stars send out both heat, light, and radio emissions, they should grow colder with time. The question is, how long before they go "black", similar to rough planets, hard for us to see? Notably, the Milky Way has had relatively few supernovas since the mid-1800s, but others, like the Firework Galaxy, have had a multitude of them at the same time. At the same time, novas are not linear, they increases when interstellar clouds get affected by gravity. Therefore, the second question is, how can man, theoretically, estimate how many "dead" neutron stars and magnetars linger in a galaxy, creating invisible gravity effects. Effects we account to dark matter? Likely not all of it, but can these burnt-out carcasses be ignored?

Maybe it is a neutron star which formed unusually like a bunch of white dwarves combining? 🤔

There's a fish flying over your house?

The universe is not old enough for a neutron star or white dwarf to have slowed down this much is it??? How baffling!

It's still trying to work out the most efficient posting frequency for its local social media.

Since pulsars spin slows over time, perhaps this is just a very, very, old pulsar.

With life because there is light active with humans like us.

Neutron stars are the most extreme objects in the universe followed by black holes are the only thing more extreme than a neutron star in the universe. Say what 😮

I'd say neutron stars are *more* extreme than black holes. At least black holes have enough modesty to hide their freaky sнιτ behind an event horizon, but neutron stars let it all hang out -- blasts of gamma rays, magnetic fields strong enough to rip molecules apart, showers of heavy elements, you name it. Whenever a neutron star does something, it affects you.

I sometimes get helicopters flapping around in the middle of the night here. It is about as annoying when I'm trying to sleep as when you're trying to record a video, I gather.

@DrBecky some flat Earthers/geocentrists take this as evidence for a flat, stationary earth. Forget the flat earth part, because we get this data from satellites, which of course rules out a flat earth right there. But the stationary part…am I correct in saying that this anisotropy couldn’t be proving that because in order to see this anisotropy in the quadrupole and octopole, we first had to calculate the dipole, where we corrected for Earth’s motion? ALL of its motion (rotation/revolution/precession/travel through the galaxy, galaxy travel through the universe, etc)? Do I have this right? Thanks!

I am 28 years old and have set out to attain a college degree. I am in my second semester. Currently, I am pursuing a degree in humanities. My question is this, Dr. Becky: is it ever too late to get into physics? I desperately want to change to astrophysics, but I worry that I didn’t take enough maths in high school.

Change your base 10 thinking for a minute.

Oh, sorry for that inconvenicene, I was moving around some pulsars to redecorate my local spacetime for a birthday party, didn't realize if I used one as a beacon on the back of my space bunny it would shine towards habitated planets... I'll make sure to turn it off next time I'm home, sadly I'm a few billion megaparsecs out, so you guys will have to put up with it for a while... You know, space bunnies are so skittish, they fly in perfect circles until they find a rogue planet to chase and simply run off... I thought that putting a pulsar as a beacon on mine might be a good idea to find it, if it did run off while I was travelling. I think I'm just going to get a cat, if you could spare one, though, if that's okay with you? Oh, and do you take intergalactic credits, if you decide to let me buy one?

Er, Dr B, what is a "square degree across"? "Across" has dimension length not area.

26:42 That's not Seth McFarlane that's "Pretty-boy cum face"

I love your content. I was also a Chinook flight engineer and still work on them as a mechanic. This is not the crossover I was expecting, but I love it.

0:21 lol dem pokemons

It's clearly space aliens.

Is it possible for stars to spin in multiple axes? 🤔 (Resulting in the ‘lighthouse’-angle to rotate as well so we only get a pulse every 54 minutes when it lines up with earth again?)

Did any one else come here to say “FOR SUPER EARTH! FOR DEMOCRACY!!!”

What if there was a small black hole orbiting the "pulsar" slowing its spin time? Do you think it's possible?

"Looking for a slow-spinning pulsar. 6'5", blue eyes..." 🤣

MeerKAT is my new favourite telescope name. I can just picture it perched on a hillock, constantly scanning its surroundings for ... things.

Dear Advertisers, All ads get skipped.

There was an astronaught that showed what happens when an unbalanced weight object is spinning. It spins fine for a bit, but then then axis suddenly reverses. Could an unstable axis be a solution to the slowest spin as it flips?

It’s Digby messing with the key fob again, looking for his lost Nibblonian space ship. He and Nibbler really need to quit drinking. Somebody find a synthesizer and a good set of speakers 😉

Don't worry Dr. Becky, The Russians are coming! Strength is Power @_@, err... Truth Will Out! Or.. The introduction to Animal Farm, should explain that noise you're inside your head, coming from the turned-off television.

Great, now ill have to rewatch sg1 for a 3rd time

Isn't the sun a really slow spinning star? Hence it being absurdly spherical? If you crushed it down how fast would the neutron star spin?

God sake please speak slow and calm. I cannot understand I am not a native speaker

Dr. Becky if rotation is slow maybe there's something in the central density that's slowing rotation such as a massive diamond or other object. It could also be a burp of sorts that was within the manifold of rotation that might be causing rotation to slow. Is there any definitive info that goes back in time? Daniel J Blatecky USA

Playing a bit of occams razor. Couldn't it just have a wobbly spin? So it's not slow just only points at us every 54 minutes. Was that explored in the paper?

This channel is a bug reason I got interested in astronomy and it is completely crazy to me that I get to work on long-period magnetars at the same time that this channel releases a video about it. Thank you Dr. Becky!!

ohh another one full with bs

A sad story about the effect ist a German school book that gives a much more complex explanation - and it is completely wrong. I wonder which profession the author and the lectors have.😮😢

27 days for the sun? I didn't know that. I guess that's why ejections come and go. Duh.

If we’re in a black hole the spin is what gives us our forces and emergent time and space. The source would be an infinitely rotating black hole and to us it would appear non rotational, due to quantum state lock.

Could the variability in the pulses be due to an exaggerated wobble in the stars axis? I.e. it wobbles much like the Earth but through a greater degree of magnitude over a much shorter time period!

Not sure which is cooler. This astronomical object, or that nail polish. OMG that's pretty!

Maybe it was part of a binary system where the stars were close enough to be tidally locked. After becoming a neutron star, it may have been separated from its partner by another interaction and its remaining rotational velocity is the same as its previous orbital velocity.

Heat doesn't collapse in on itself. Is there any new energy outside of heat? Cold space is repulsive to heat propulsion from cold repulsion momentum as space itself as a weak external magnetic field filled with dark heat energy outside of entanglement of mass as potential renewable energy when entanglement with mass occurs again and again. Conservation of heat energy throughout space as dark heat energy outside of entanglement of mass. Mass neutralizes repulsion within it as occupational space itself as outward force of pressure known as weightless outside of a greater internal magnetic field grounding currents through all masses in its path until resistance is overcome by open space itself and returns to dark heat energy outside of entanglement. Distance traveling increases, and the force of pressure decreases as open space at normal space heat propulsion maximum distance traveling momentum and least amount of force to and from cold repulsion. Internal magnetic fields are maximum force and least distance traveling cycling circulation patterns as hydrogen. The least amount of occupational space as outward force of pressure and least distance traveling cycling circulation patterns as mass. Mass neutralizes repulsion within it as an outward force of pressure. Mass occupies space, and as mass expands, it occupies more cold space as repulsion within and without entanglement and force of pressure expands into more repulsion. Mass falls in equalization to repulsion within and without entanglement of mass. More force of pressure has a greater impact of grounding currents of heat energy pressure in equalization to renewable heat energy absorbed and existing heat energy released from internal magnetic fields grounding currents into surrounding areas of mass as synchronization of flow equalization. Heat has to ground or burn as external heat energy released from internal magnetic fields disolving into external heat energy as fire. External heat energy within mass is constant external heat energy. Heat is the lifeblood of everything as external heat energy degrees of temperature equalization throughout space and mass as quantum internal magnetic fields expand into occupational space and shared internal magnetic fields grounding currents. Cold internal magnetic fields grounding currents sharing internal magnetism grounding currents as oxygen and hydrogen as water. Temperature equalization of shared internal magnetic fields grounding currents through all masses in its path. Heat equalization to force of pressure known as weight within a greater internal magnetic field grounding currents through the nucleus or core. External magnetic fields surrounding the monopole of repulsion to heat propulsion from cold repulsion momentum. Normal space is filled with dark heat energy outside of entanglement of mass. Hydrogen under extreme pressure expands into helium. Heat expands as heat energy propulsion. Physics 101. Heat can't collapse in on itself. Physics works. Mass is heat energy throughout space as space and mass in equalization. Stars replenish heat energy throughout space as dark heat energy potentially renewable heat energy when entanglement with mass occurs. Heat currents grounding through mass as renewable dark heat energy as mass. Density can't exceed resistance within occupational space itself. Cold repulsion is neutralized by heat energy cycling circulation patterns of internal magnetic fields within mass and without mass equalization. Hurricanes in space are external magnetic fields disolving proximity internal magnetic fields grounding currents by disrupting normal space repulsion to heat propulsion from cold repulsion momentum. Mass has to be hit with cold repulsion to heat propulsion from cold repulsion momentum, or it becomes heat propulsion from cold repulsion momentum and disolves internal magnetic fields outwardly force of pressure from within mass. It decays as external heat energy waves outside of entanglement of mass. Normal space repulsion is necessary for internal magnetic fields to redirect trajectories of currents flowing back into itself as mass occupies space as neutralized repulsion within the weakest point of repulsion. External magnetic fields disrupt normal space repulsion by hurricanes of heat energy neutralizes repulsion of normal space by redirected trajectories of external heat energy towards the greater magnetic field flow as the weakest point of repulsion as neutralized repulsion within its circulation patterns. Theoretically factual probability that works with quantum physics without gravity. Mass is always outward force of pressure. Physics works.

Absolutely fascinating find. I still think it is a White Dwarf that got somehow "ejected" from whatever made it spin but there is still residual material falling on it, making it pulse.

For those want to understand the universe here it is. In black (Dark) and white (Light). And God said. Let there be light. What is light? Light is energy and energy is defined as E=mc or Energy equals Acceleration. So let there be light can be interpreted as Let the be acceleration with a speed limit. Energy can be neither created nor destroyed. Only transformed. The universe went from an unaccelerated state to an accelerated state. The laws of physics dealing with Acceleration. Newton's law of motion F=ma, motion in space. And E=mc, motion in time. When god said 'let there be light' he didn't create an event in space. He created an event in time. He started the perpetual motion machine that transforms energy into acceleration and acceleration into energy. F=ma? Dark Universe physics where acceleration is unlimited, unbounded, infinite, undescribed, not existant. Absolute Zero. There is nothing in the Dark Universe until you define it. Upon which it becomes bounded. E=mc. Light Universe physics. Acceleration is now limited to the speed of light. The Light Universe is a now finite universe bounded by the speed of light. What Becky is doing is using physics from the Dark Universe, where anything is possible because there is nothing really there. And applying them to the Light Universe where there are limits. F=ma? Mass can increase as Acceleration increases but you can have infinites. E=mc? You now have limits on how much acceleration you can have which limits how much mass you can have because mass comes from Acceleration. Or rather, mass is consumed/converted in the acceleration process. E=mc. Acceleration goes up, mass goes down and vice versa. And this fact is demonstrated in every observation within the Light universe. F=ma? An infinite unbounded, limitless universe. So no, neutron stars do not have high mass and high acceleration. And neither do black holes. They are the extreme opposites. Low mass/high acceleration. High mass/low acceleration. Sports cars accelerate faster than loaded semis. If mass was the acceleration factor, don't you think the opposite would be true. Hot water has less mass than cold water. If mass created acceleration, wouldn't it be reversed? Now you know the truth. These people are either woefully ignorant or outright scammers. Nicholas Tesla called them out for being frauds. He lacked the vision/experience to explain why Relativity is mathematical nonsense. Galileo proved that there is no mass attraction but was blown off and locked up in prison when he persisted. E=mc. You can't have high mass and high acceleration. You exist in a bounded universe limited by the speed of light.

Not only was this very interesting (as expected!), but that was one of the funniest blooper segments in a while. Dr. Becky gets miffed!

How do neutron stars magnetic fields?

I love capital WEIRD things in science!
