Undergrad Why can't LIGO detect collisions of super massive black holes?
Thanks for solving IBEX! -
Undergrad Why can't LIGO detect collisions of super massive black holes?
I've also read about the "final parsec problem" about how the final mergers of binary smbh can be very drawn out. -
Undergrad Why can't LIGO detect collisions of super massive black holes?
I guess if you had to pick one range to measure it is logical to select the one to record the much more frequently occurring events. It still blows my mind that LIGO could be made to be sensitive enough to measure such small changes. -
Undergrad Why can't LIGO detect collisions of super massive black holes?
I thought it was on a segment of Science Friday on NPR. -
Undergrad Why can't LIGO detect collisions of super massive black holes?
Exactly right, they have been recording stellar black hole collisions. I was hoping it was just the frequency/ timing issue but I thought I heard a LIGO scientist in an interview say they couldn't measure a super massive black hole collision, so I wanted to check with this wonderful community! I... -
Undergrad Why can't LIGO detect collisions of super massive black holes?
Does anyone know, and is there an instrument that could? -
Undergrad Is the inflationary universe a scientific theory?
This is the provocative question posed by Sabine Hossenfelder in her article in Forbes, covering the ongoing debate of inflation critics like Paul Steinhardt (once one of the theory founders) and scientists who develop models of inflation. Link to her article... -
Graduate Dark matter and energy explained by negative mass
Here's Sean Carroll's take on the study: https://twitter.com/seanmcarroll/status/1071066682234261504 -
Graduate Dark matter and energy explained by negative mass
Great respect for Sabine Hossenfelder. I found her response to a poster named DreamChaser to be of particular interest, DreamChaser said that they liked the study because it was elegant in offering an explanation for both dark energy and dark matter (I will admit that I also found this... -
Undergrad What happens to a star's heat when it gets torn apart by a black hole?
So, were it not for Harking radiation, the event horizon would seem to an outside observer to have a temperature of absolute zero? -
Undergrad What happens to a star's heat when it gets torn apart by a black hole?
Thank you Ibix, helpful explanations. -
Undergrad What happens to a star's heat when it gets torn apart by a black hole?
Yes, I meant the thermal energy of the star. I have read that black holes are extremely cold, much colder than the 2-3 Kelvin of space, and the larger the black hole the colder it is. So does the thermal heat get transformed into mass as it enters the black hole? -
Undergrad What happens to a star's heat when it gets torn apart by a black hole?
I'm sure this is a really basic question for the black hole experts here. Consider a situation where a star approaches and then crosses the event horizon of a super massive black hole, the star gets torn apart eventually undergoing spaghettification as it approaches the singularity. My question...
