A Boston University physics professor took students from the dawn of time to the formation of the Earth to the end of the universe in a lecture Tuesday.

Professor Larry Sulak gave a lecture titled ‘The Big Bang to the Death of the Universe’ before about 20 people as part of the College of Arts and Sciences ‘Conversations with Physicists’ series.

CAS Economics Administrative Coordinator Norma Hardeo introduced the lecture as the first of many she said she hopes will be ongoing conversations between faculty and students at BU.

The importance of holding such events on campus is to integrate another element as ‘part of a liberal education to understand what other subjects are up to,’ Hardeo said.

Hardeo said he had hoped there would be a bigger budget for the series, but the school did not give the department enough money to do so.

The lecture focused on big physics questions of today’s scientific era.

‘Physics is a field too many people are afraid of,’ Sulak said, encouraging students to participate in the interactive discussion. ‘We’re here for a conversation.’

Sulak, who received a doctorate in physics from Princeton Universityfocused on two theories of the origin of matter and the universe: the Standard Theory of Particle Physics and the Standard Theory of Cosmology.

Cosmology is the scientific study of the large-scale properties of the universe as a whole, using the scientific method to better understand the origin.

He focused on the questions of what people already know and how they use it it by taking the audience through theories from the very beginning of time and space to the theories about the end of the universe.

Sulak analyzed the particles physicists say humans came from and hypothesized about the way humans will eventual decay into light.

He said as the universe expands, the temperature on Earth drops, adding that factors such the sky being black prove the universe is not infinite and is always changing.

Students in attendance ranged from English to geology majors, all hoping to educate themselves on the topic. Many said they enjoyed the lecture overall.

CAS junior Justin Jahng said he thought the lecture was a good experience, though he had come with different expectations.

‘I expected it to be more about space,’ he said. However, he did say he enjoyed the micro-macro physics approach to the topic.
