He doesn't consistently have good knowledge. He says everything "has" gravity. Nothing "has" gravity, and it is not a force. Gravity is the curvature of spacetime by objects with mass, and that curvature effects other objects and light (well the entire electromagnetic spectrum).

THATS WHAT I SAID :) SOUNDGARDEN BLACK HOLE SUN

Well this video is titled "What If" at the beginning...

Sirius he says it's at the end of the video, he says our sun will supernova instead of turning into a black hole because it's too small ( I think that's what they're on about) obviously it will do neither it will end in a white dwarf as our sun is way too small to go off in a supernova or turn into a black hole or neutron star

In fact the sun doesn't have enough energy to even supernova it will let off planetary nebula and then white dwarf.

I agree with you the sun's mass is to small for it to go supernova, the sun would need at least 10x more mass in order for it to go supernova. The sun will eventually turn into a white dwarf, it has to go through the red giant phase first. Once the sun is a red giant it will possibly consume the inner planets including the earth. While the sun is a red giant it will start to shrink and loose mass at the same time, and once the sun turns into a white dwarf the sun won't be as bright as it is today.

Yes, black holes are fun. I'll do one about black holes in the future!

Carolina Mariño i think u told about gravity to KindScientist , who told you people that gravity depends on mass and sun as black hole has same gravity ? Newton or Stephen Hawking told you ? I have seen secret materials mass of 200 grams (not weight )and they have enormous gravity when activated ......

Well you see most people popped out of a females vagina. But in star wars Darth Vader Popped out of a black hole

@@ActionLabShorts black holes are not fun. Trust me, I've been in one

Thanks!

I love this video great job keep up the amazing work

I don't wanna die

What da whyyy Djhslwhdos sudbx You liar Wait for a Quintillion years And 1000000000000000000000000 Quintillion Century Your believe that boy or girl I don't care you I don't believe you

Lol I thought the same

I think what you’re thinking of is a coronal hole, not a black hole. Black holes don’t just appear on a star and then somehow engulf it, that’s not how it works.

That sounds like a nightmare

You should make that into a movie

Wait it's real I believe you now it's small star

Lee Sin Main lol

Lee Sin Main who knows with these nerds

SL. k who knows, theres different stages of any star and one day the sun will come it through its limit

watch the video until the end

Alltime 10's Not quite. The largest black hole is the size of 1000 suns

Sun + black hole = much more gravity than needed to pull the entire solar system inside. Black holes have been observed between 3.3 times and 40 _billion_ times the mass of our sun. Typical black holes are on the low side, up to 10x our sun's mass. The biggest ones are generally the core of galaxies. (Possibly all galaxies.) Considering just us vs. the sun: The sun is 99.8% of the solar system's mass. All the planets and smaller bodies make up only 0.2% of the system. With such a small amount now in delicate balance, an additional star or our sun with an added _much more massive_ black hole would very likely swallow it all. This might eventually lead to new planets forming, but the ones we know would crash into the new XL star (or slightly-larger-than-it-was black hole) that formed when the two joined together...or exploded. If you want a more detailed account of how it might feel, try searching Quora for "Everybody Dies™". I'm sure Dave Consiglio or a similar writer has killed us all in this fashion, at least once! You'll surely discover many more nonsensical ways humanity can end in fiction, as well.

it's impossible for the sun to turn into a black hole, because the sun is to small due to its mass.

No sun will not be home black hole forever

+dinah barker all mass has gravity

ActionLab Vlogs not the Moon u can not stand on it and walk properly,so therefore the Moon Doesn't have gravity

@@dinahbarker3577 don’t you have mass to stand on the moon?
