Michio Kaku's CONCERNING New Discovery About Betelgeuse Supernova 2023

When we think of stars, we probably think of tiny shiny objects in the night sky—at least, that's how we see them from down here on Earth. But you see, stars are anything but small. In fact, one of the largest stars— Betlegeuse—happens to be much larger than our sun! For years, this star has baffled scientists. However, recently, something more unsettling has been happening with Betelgeuse that's making scientists and other well-informed folks very concerned.

Since it takes 600 light years for Betelgeuse's appearance to reach earth, how do we know it still exists?

*sigh*

Betelgeuse is not a threat to Earth. It is too far away to have any significant impact on us.

NOTHING can travel faster than the speed of light.

The supernova will create one of two things, a black hole (unlikely) or a neutron star (most likely). The neutron star *might* become a pulsar or a magnetar, but it depends on the resultant mass leftover to form the neutron star, and how fast it ends up spinning, and in what orientation. It is very unlikely to be pointed towards us, in any case.

No matter what, though, it won't become anything more than a pretty light show for a few weeks/months, and eventually a pretty close-by nebula.

If Betelgeuse did explode, we will realize 600 years after it did, we only see the ghosts of the stars after all...

[herbcraven]

Do Betelgeuse's pulsations somehow affect the narrator's accent? It seems to oscilate between British and American.

With headlines like these it’s a miracle we haven’t been destroyed by (insert anything space related here) hitting the earth at 2 lighter years per hour

[patrickodonnell]

We can't even get the daily weather right consistently and now we're to believe anything we are told about a star that is light-years away?

[margaretbowen]

"They" just have to keep the fear flowing don't they?

1 light year is about 6 trillion miles- 186, 000 Miles per second- The speed of light in a vacuum- Times 60 seconds equals 1 light minute- Times 60 minutes equals 1 light hour- Times 24 hours equals 1 light day- Times 365.25 days equals 1 light year

[martygould]

You said Betelgeuse so many times a crazy clown like guy appeared and tore up my apartment.

[sigep]

As long as no one says its name 3 times, I think we'll be okay.

[stephenjablonsky]

Live each day as if it is your last...that goes for stars too

The most significant effect Betelgeuse has on us is the multiple mispronunciations in this video alone.

BTW, 1 LY is approximately 6 TRILLION miles, not billion. 4 LYs is roughly 24 trillion miles. Alpha Centauri (or Proxima Centauri) is about 4.2 LYs from our star system. IF Betelgeuse has not already explode in a supernova, we won't know about it for AT LEAST another 600 yrs, and any debris that makes it this far won't arrive for MILLENNIA after that.

If it has already exploded, and IF it occurred more than 500 yrs ago, then sometime in the next century we'll be treated to an amazing cosmological event (pretty light in the sky).

As it shrinks it gets brighter, as it expands it cools and dims.

[unclefester]

If Uranus is still intact we're doing allright....😎

The last one wasn't in 1604. It was the last brightest one we saw. But there was another one in the 1880s that was visible with the naked eye and another one in the 1980s that was visible through telescope

[beornthebear.]

Red giants are typically unstable, and the brightness fluctuates. I have observed Betelgeuse with my naked eyes growing from white (low brightness so my eyes can't detect the color) to bright orange (very bright). If red giants are massive enough, they will supernova, or explode, throwing elements everywhere. As said below, this star may have exploded already, but we have yet to see it. If we do see it, it may be visible during the day, but I think it is too far away to do any relevant damage to Earth.If it turns into a pulsar and blasts gamma rays in our direction, there may be problems, but the gamma ray jets would need to point right at us. Also. a light year is not billions of miles, but about 6 trillion miles. Six hundred light-years x 6 trillion is many miles away. The Crab Nebula star was noticed in the sky when the brightness of the explosion hit Earth, and granted, it was further away, but the blast still would need to travel 600 light years to hit us, and unless it became a pulsar pointing right at us, I doubt it will be more than a good view of a supernova. Also remember, our sun puts a protective shield around the Solar System just as our Magnetosphere protects us from the sun. That is 2 layers of protection. Once it starts converting its last elements into iron, it's going to blow (or maybe has already and we haven't gotten the memo).

[prodigalpriest]

I'm not going to lose any sleep when Betelgeuse explodes. It's over 500+ lys away from us.

Got a bottle of 12 year old single malt waiting for the right moment

[gedofgont]

The best thing about this video is the incredible, morphing, English/American voiceover!

[chopperchuck]

what ever is happing with Betlegeuse happened over 600 years ago
