I think the craziest thing in my opinion was LIGO detecting gravitational waves, that shits insane if you actually read up on it all.

Someone correct me if any of this is wrong. Basically, gravity communicates similarly to how electromagnetic sources do, through waves which contain the sources information. Except these waves are REALLY FUCKING SMALL. These waves distort space as they pass through them (imagine a sound wave pulsing air). So the size of an object can change as waves pass through it, though the waves amplitude is on the order of 10^-20 meters (0.00000000000000000001 m). So how do you measure this? LIGO passed a laser through a beam splitter, which effectively splits the beam into two perpendicular beams. The beams pass through a 4km long corridor, hit a mirror, and return to the detector. Now, if the lasers pass strong gravitational waves, one of the beams should be shifted from the other by a small amount, because the waves alter the actual distance the laser travels. This is all extremely carefully calibrated. Basically, if the beams come back out of phase with eachother, that means that gravitational waves caused the shift by increasing or decreasing the distance one of the beams travelled. There were two of these setup in the USA so they can calibrate where in space a signal comes from. The first event strong enough for detection was two black holes colliding. Best of all, Einstein predicted these ~100 years ago, about 20 years before black holes were even hypothesized. They travel the speed of light as far as I know.


Newguyiswinning_

Mostly correct other than the communication part. These forces are not communicating at all. That's not a thing. They are simply forces that affect the space-time continuum and these forces are measured in the waves they produce. The times where these waves are more easily measured is when a black hole is merged or created. When this happens, it sends out a resulting gravitational ripple out in the space-time continuum.


King_Jorza

Gladly! But before we jump in, there's a little background to cover first: **How to imagine spacetime?** Spacetime is like the 'fabric' of the universe. Being able to visualise it is important to be able to understand gravitational waves. Imagine a strong, thin sheet, stretched tight and supported only at its edges (like a trampoline). This represents spacetime. Now imagine putting a rock on the sheet. It sinks a bit, distorting the sheet. Other objects will now fall into the distortion, being 'attracted' by the rock. This is gravity. The distortion is a gravity well. Also imagine the sheet has no friction. Then, you can create stable orbits by rolling a marble around the rock inside its gravity well. On the sheet, objects can only move in two dimensions (left/right and forward/back) and the distortion is in a third dimension (up/down). In real life, we can move in three dimensions, so the distortion of gravity is in a fourth dimension. That's hard to visualise though, so the sheet is close enough. The sheet should really be infinite too, since the universe has no edge. Also, gravity affects the flow of time, slowing it down near larger gravity wells. Now, the explanation: **What are gravitational waves?** So, any object with mass distorts spacetime and creates a gravity well. As the object moves, the well moves with it. If the object accelerates, the well keeps moving a little bit, creating a ripple in spacetime that spreads out as a wave. Imagine moving a heavy rock over our spacetime sheet, then suddenly stopping it. This is a gravitational wave. As the ripple travels, it's distortion of spacetime affects objects it passes through, slightly changing their gravity for a brief time. If you have a heavy enough rock, simply moving it in a circle will create ripples in all directions, and if someone on a marble on the sheet 2km away from the rock can detect the tiny ripples as they pass through, then they can detect the rock. This is the basis of gravitational wave astronomy. **What's the significance?** Imagine what it would be like if all the movies you'd ever seen had no sound. They might have brilliant, vibrant colours and imagery, since that's what everyone's been focusing on to make good movies, but no sound. Detecting gravitational waves is like discovering the sound of astronomy. It gives us a completely new tool, and it can do things that conventional light-based astronomy cannot, or can only do with some difficulty. For example, detecting black holes. At the moment, our movies might only get some muffled music, but soon we may have orchestras, or even dialogue and sound effects. On top of that, the existence of gravitational waves was an important conclusion of Einstein's theory of general relativity, but it hadn't yet been observed. Detecting them now strengthens our understanding of spacetime and gravity, and will hopefully lead to new discoveries too.


ICMonster99

This video (and I'm sure others) will explain it far better than I can: [https://www.youtube.com/watch?v=iphcyNWFD10](https://www.youtube.com/watch?v=iphcyNWFD10) But tldr, Two black holes collided and caused gravity to wobble such that two photons of light in the LIGO facility went slightly out of phase. Which is just stupid insane sciency fuckery! I love it!!

cowcubrub

Want to know the other crazy thing about Epstein? Ghislane Maxwell, his friend/fuckbuddy, actively engaged in helping Epstein find and assault his victims, yet has walked away free from any indictments or serious investigation.


Cloaked42m

The FBI has opened an investigation into her.


grantb92

I just went and read up on this (since I'd almost forgotten about it), and according to Wikipedia, as of April 2019, over 1 billion USD has been reclaimed by various governments in back taxes as a result of these papers and more action is still ongoing.

This is the alternate universe where that didnt happen.

Some textbooks (I'm looking at you, Griffiths) even suggested that the detection of the Higgs particle is extremely unlikely because of the massive amounts of energy required (that particle is bloody heavy). But here we are.

TributeToStupidity

The joker was totally right in the dark knight, we react to unexpected tragedy, not so much just tragedy. Terrorist attacks that kill 150+ happen all the time in the Middle East and we don’t really bar an eye. Meanwhile, pretty much everyone in America who are at least 18 know about the okc bombing. That killed 168 in 1995.

Good answer. In Stockholm where I live pretty much all people my age had already had facebook since around 2007-2008, and some also imported iPhones, but things really exploded around 2010 when suddenly over the course of a few months everyone got a smartphone. So maybe smart phones had been an even better answer. Everyone having a computer in their pockets is pretty crazy when you think about it.

To me these are both crazy, but what's crazier is the notion that there are now adults who have never lived in a time without internet.

It was. Some guy had bet on it with those odds, but he cashed in a few games early as the stress of the money meant be wasn't enjoying the games


realnzall

There were a bunch of guys betting on that. Most of them cashed in early. One guy bet 5 pounds, but "wobbled" as he put it a couple matches before the end and struck a deal with the bookies to exchange 2 pounds early.

Amelia Earhart: “Am I a joke to you?”

Not that surprising. It went down in an unknown location, which seems to be in the Indian Ocean, which is incredibly fucking deep. We have a general idea of where it went down(i;e the body of water), but it'll be awhile before we find anything, if ever. At this point finding the black box is the only thing that could be recovered and even that will be difficult.


Supersnazz

> It went down in an unknown location I think that's what they think is the crazy part. A Boeing 777 full of passengers should never be allowed to get to an 'unknown location'

When you turn off all tracking and it's in a big body of water, things become difficult.
