Interstellar has lots of fun with that, as does Stargate SG 1’s “A Matter of Time” (I particularly appreciate the violations of the laws of physics in the latter, to the confusion of the military scientist character: “from everything I think I know about General Relativity, that can’t happen! So you end up taking advantage of a bunch of deals, and purchase much more than you intended to in the first place. In short, the escape velocity of any celestial body — the velocity at which an object needs to travel to escape the gravity of a planet, star, or other body, is dependent on the mass of the body and its diameter.

Astronomers use our sun's mass as a measurement for huge things in the universe, such as black holes. Intermediate mass black holes are believed to be in between the weight of a stellar and supermassive black hole. So a fun fact is that if you could instantaneously magic away the Sun and replace it with a black hole of exactly the same mass, the the Earth would not be pulled into it.One is that they could be formed from lots of smaller black holes combining over a long period of time (and we have actually detected gravitational waves that we think are from stellar mass black holes combining – thanks LIGO and VIRGO! A black hole that's the mass of the Sun will only be a few kilometers in diameter: smaller than any actual star, white dwarf, planet, or even neutron star in existence.

The supermassive black hole at the center of our galaxy, Sagittarius A*, flares brightly in X-rays .

Among the many things that Black is grateful for: that 2023 has seemed to be the first year since the pandemic where “things felt almost normal. And why he concluded his rant by telling viewers: “As bad as you think 2024’s going to be, it’s going to be worse than that. Christina completed her PhD in Astrophysics at the University of Manchester in the UK studying evolved stars.

Now, let's imagine the same exact puzzle, only this time, let's replace the real, physical planet Earth with a black hole that's exactly the same mass. We can often find evidence of this in many different wavelengths of light, even including visible signatures and jets in many instances. Yes, they have a lot of gravitational pull on the space in their vicinity, but that just causes the matter around them to accelerate rapidly.

FIRE’s 2022 College Free Speech Rankings are based on the voices of more than 44,000 currently enrolled students at 208 colleges and are designed to help parents and prospective students choose the right school. Believe it or not, that actually contributes to black holes devouring less matter than they would if only isolated, individual particles fell into it. On Tuesday, Black took a few minutes to address the inevitable recaps we’ll all be doing—if only in our own heads—of the past 12 months, and to assure viewers that things weren’t so bad. If you are traveling very quickly or if you are standing close to something very large (say for example, a black hole) then time – from the perspective of someone stationary or a long way away from the something very large – appears to move more slowly for you than the that other person.

I also figured this was a good topic to chat about – a tad outside the norm but I figured that was ok. Christina currently focuses on studies of planetary atmospheres and is a current member of the Mars Science Laboratory (Curiosity) Science Operations Team. Loss aversion, restraint bias, and the bandwagon effect are mental blindspots that impact decision making in all life areas, ranging from the future of work to mental fitness.If you've had a child (or been one) since the 1970s, you've probably seen it in action for yourself. There are a few different types of black holes: stellar mass black holes (black holes that weigh a few times the weight of the Sun up to quite a lot of times the weight of the Sun), supermassive black holes (literally millions of times heavier than the Sun), and intermediate mass black holes (somewhere in-between). Not all massive stars form black holes, some form pulsars, it just depends how much of the star gets blown off in the supernova, as there has to be enough of the star left that gravity forces it to collapse down and down and down until all that stellar matter is contained in an infinitely small area (a “singularity”).
