Interview: Dr. Ken Olum, Boltzmann Brains, Cosmic Strings and Gravitational Waves

My guest is Dr. Ken Olum, a research professor at Tufts University. His primary research is into cosmic strings, and how they could be detectable through techniques like gravitational waves.

Dude you are hammering in these interviews. I have never been so entertained.

[watchison]

Again Fraser, these interviews are fascinating. I really enjoy your interviews. They are direct by you in a way that expands my non Dr mind without being Nasa childlike/scripted. Thank You!

[jasonchen]

I really enjoyed the interview with Dr. Ken Olum.
I will look up more of his work because of this interview, hadn't heard of him before. Great channel, interesting topics as always. thanks for your episodes.

[stewitr]

Another brilliant interview. Thanks Fraser.

[davidlewiz]

In an infinite universe with multiple versions of me, at least one of me understood everything in this interview and that makes this version of me happy. 😃

[tlog]

Totally agree. The interviews are great keep them coming

[porowozek]

My Boltzmann brain hurts a little. I'm gonna fluctuate out of the Universe and relax a bit. Great interview Fraser!

[martinsz]

You are the man dude, good job. Great channel!

[jayf]

What a nice guy. I'd say he's a great teacher.

[neutechevo]

Very interesting conversation with Dr.Olum.
Especially the later part with the Cosmic Gravitational Background is really intruguing as it maybe bringing us closer to a broader picture, finding out the Fabric or Structure of our suroundings.
I'll leave a question if i may..
'Could the material that black holes are eating up, end in filling the supporting structure of the Universe and that when eventually every black hole evaporates and also with the great expansion, the whole Structure will Collapse? Thank you.

[MacM]

Sounds like an intriguing conversation. No multiverse though, at least in my opinion.

[Corvaire]

29:00 Dr. Olum quantified time right before our eyes. ;O)-

Itd be nice to hear a techincal conversation about any persistant anomalies from LIGO and classifications of Anomalies vs Noise, thier confidence levels in anomaly classifications.. (Ok to be honest, Im curious about hypothetical ET tech/ local gravity manipulations) From the limited info I can find, I dont have the skills to correctly interpret LIGO data in journals, , but has persistent 'glitches" that are anomalous, but classified as the equivalent of non-events, local interference, or calibration issues.

to watch this interview you either have to be a immense nerd or hit an immense blunt

[ryandugal]

Love it . Love this content. I want your job.

[damianGray]

I've always hated the 'observer' terminology in regards to quantum changes. It always makes it sound as though its the conscious act of observation by an intelligent agent that causes the change, like telepathic magic, rather than the fact that quantum is so small that anything we could use to measure affects the experiment.

[LuciFeric]

All black holes are also white holes with time like paths to the infinite past, and the infinite future.

[ToxisLT]

This was AWESOME!
please bring James Randi back someday!

[captain_context]

oh dear.... Infinite copies of us out there in an infinite space. Christ, how 1980s. Moving on.

[MyLifeInVideos]

So we are all connectedto each copy of ourselfs. because one of those copies of you would be thinking about this version of you while your thinking about that version of you at the same time so in that sense we are connected to all copies of ourselfs
