On June 28, 2009, Hawking threw a party for time travellers. The next day, he sent out the invitations. "Copies of it will survive in one form or another for many thousands of years," Hawking later said in the documentary "Into the Universe with Stephen Hawking."
"Maybe one day, someone living in the future will find the information and use a wormhole time machine to come back to my party, proving that time travel will, one day, be possible," he said.

Sir Roger Penrose explains why Big Bang isn't the beginning of the universe.
Some scientists claim that the universe did not have a beginning. Some theologians contend that the universe did not need a beginning. Yet the universe is expanding, and so run the movie in reverse and there seems to be a beginning. What stakes are riding on whether the universe had a beginning?

The Nature of Space and Time
by Stephen Hawking, Roger Penrose
Einstein said that the most incomprehensible thing about the universe is that it is comprehensible. But was he right? Can the quantum theory of fields and Einstein's general theory of relativity, the two most accurate and successful theories in all of physics, be united in a single quantum theory of gravity? Can quantum and cosmos ever be combined? On this issue, two of the world's most famous physicists Stephen Hawking and Roger Penrose disagree. Here they explain their positions in a work based on six lectures with a final debate, all originally presented at the Isaac Newton Institute for Mathematical Sciences at the University of Cambridge.4 647

Soon after the announcement of 2020 Nobel Prize for Physics, lot of people contacted us to provide the original 1965 paper published by Roger Penrose on "
Gravitational Collapse and Space-Time Singularities".
It's worrying that despite being publicly-funded organization 'American Physical Society' doesn't allow free access to the journals. Nevertheless, we are working on it and will soon provide the same.4 647
Quantum Computing as a High School Module
Quantum computing is a growing field at the intersection of physics and computer science. This module introduces three of the key principles that govern how quantum computers work: superposition, quantum measurement, and entanglement. The goal of this module is to bridge the gap between popular science articles and advanced undergraduate texts by making some of the more technical aspects accessible to motivated high school students. Problem sets and simulation-based labs of various levels are included to reinforce the conceptual ideas described in the text. This is intended as a one week course for high school students between the ages of 15-18 years. The course begins by introducing basic concepts in quantum mechanics which are needed to understand quantum computing.4 647
In the phone interview with Adam Smith, recorded just after the announcement of the 2020 Nobel Prize in Physics,
Roger Penrose recounts the story of how a particular crossroads held the key to his seminal 1965 paper on the theoretical basis of black holes. In the second half of the conversation he goes on to explain some of his latest work, describing how black holes are the basis for the second law of thermodynamics, and suggesting that signatures of black holes from a previous universe might be faintly apparent in the cosmic microwave background radiation.4 647
"I'm thrilled to receive the prize and I take very seriously the responsibility of being the fourth woman to win the Nobel Prize [in physics]. I hope I can inspire other young women into the field. It's a field that has so many pleasures."
