Despite our knowledge of the laws of physics, and the successes of the Standard Model and General Relativity, there are a number of observations out there in the Universe that still lack a complete explanation. From star formation to high-energy cosmic rays, the Universe still has its mysteries. Although we've discovered a great deal about space, we still don't know it all. For example, we know that dark matter exists, but we don't know what it's properties are.
Once you fall into the event horizon of a black hole, you can never escape. There’s no speed you could travel at, not even the speed of light, that would enable you to get out. But in General Relativity, space gets curved by the presence of mass and energy, and merging black holes are one of the most extreme scenarios of all. Is there any way that you could fall into a black hole, cross the event horizon, and then escape as your black hole’s event horizon gets distorted from a massive merger?
In the years prior to World War II, physics was in an odd, post-revolutionary state. Quantum mechanics and Einstein's General Relativity had turned our picture of a classical, deterministic Universe upside down. It was replaced with indeterminate states, wavefunctions instead of particles, and a fabric of spacetime that could be bent, distorted, and could even have holes poked in it. Yet there were many open questions that didn't have sensible answers.
Muck Rack makes it simple to find people, tweets, or articles that mention any name, keyword, company, hashtag etc. We've compiled this guide to help you make the most of your search.
Selecting a term
Start searching tweets, articles from media outlets, articles mentioned in tweets, journalists'
names, titles and bios with some suggested searches:
Companies or Topics (e.g. iPhone, Microsoft)
Phrases (e.g. "cloud computing") — use quotes to keep the terms together
Twitter handles (e.g. @username) — returns those who have mentioned or replied to
Names (e.g. "David Pogue")
Hashtags (e.g. #sxsw, #london2012)
Bio details (e.g. vegan, Olympics, father)
Muck Rack's Advanced Search allows for many boolean operators.
Find results that mention multiple specified terms, use AND or
+. For example, ensure each result contains both Elon Musk and Mark Zuckerberg by
searching Musk AND Zuckerberg or Musk + Zuckerberg.
Use the operators OR or , to broaden your search when you'd like either of
multiple terms to appear in results. (This is the default behavior of our search when no operators
are used). For example, results will contain either cake or cookie by searching cake OR cookie or cake,cookie
Use NOT or - to subtract results from your search. For
example, searching Disney will yield results about the Walt Disney Company as well as Walt Disney
World Resort. To exclude mentions of Disney World, search for Disney -World or Disney
When using one of these operators with a phrase, enclose it in quotation marks. For example, you can
find results about smartphones excluding Apple's iPhone 4S by searching smartphone -"iPhone
Exact case matching or punctuation
If you're searching for a brand name or keyword that relies on specific punctuation marks or capitalization, you can
find results that match your exact query by adding matchcase: before the keyword you're searching for, like matchcase:E*TRADE .
Use parentheses to separate multiple
boolean phrases. For example, to find journalists talking about having fun in Disney World or
Disneyland, search for ("disney world" OR disneyland) AND fun.
An asterisk can be used to search for any variation of a root word truncated by the asterisk. For example, searching for admin* will return results for administrator, administration, administer, administered, etc.
A near operator is an AND operator where you can control the distance between the words. You can vary the distance the near operation uses by adding a forward slash and number (between 0-99) such as strawberries NEAR/10 "whipped cream", which means the strawberries must exist within 10 words of "whipped cream".
