Warp Drive and Aliens: Bryan Gaensler Public Lecture

This was recorded on my 50th birthday so thank you! One thing I'd like to point out about UFO's that Mr. Gaensler wholly neglects to consider is that while yes, we do have cell phones with somewhat decent cameras, they are mainly designed for close up shots and not distance. It is also very difficult, if not impossible, to focus them on small objects that are far away, and especially anything in bad lighting or at night. For example, watch a plane fly by up in the sky and try and get a good picture of it. It is difficult if not impossible even under good conditions. Secondly, most of the recent incidents of the last two decades that have been tracked by the military and also seen by commercial pilots are often over the ocean and or at very high altitudes. Lastly, we cannot just dismiss what is actual recorded evidence by the military and pilots including radar records of objects moving in and then back out of our atmosphere at extreme speeds that we humans are not nearly capable of. There is in fact a lot of evidence that cannot be easily shrugged off. While some events can of course be explained by professional skeptics such as Mick West, there are still many more events which cannot be simply dismissed as "anomalies". And to be clear, it's very disturbing that people like this, people who are apparently smart and dedicated to their profession, would so quickly and wantonly dismiss such incidents simply because it's not really within their area of study (when in fact it kinda, sorta actually is lol). My point is that these may just be the droids we are looking for. And just because we haven't figured everything out yet, it doesn't mean other potentially advanced civilizations who could have a million-year jump or more of evolution over us...already have figured things out. Just like how we are exploring Mars with what is essentially a drone, so could an advanced civilization explore us with super-advanced drones, possibly ones that are completely autonomous free-thinking AI that have developed over tens of thousands of years. Think about what we have accomplished just in the last 50 years with technology and now add 1,000 or 100,000 years to that and think where we could be. Therefore we simply cannot rule out the possibility, however extreme and unimaginable, that in various places of our galaxy we may have neighbors who are doing or have already done the same and much greater. It is estimated that there are 100 Billion or more Red Dwarf stars in our Galaxy. There's quite a lot of potential out there. So I say.. let’s keep the faith!

Ahhhh the ancient glory days: A lecture room densely packed with people.

Love this guy's simple, humble enthusiasm for his subject. Really nice lecture.

this lecture was real awesome, he really explained well how humans are behind in innovation to explore the universe

I used to write articles for the website of a semi-government org that funded "science projects". I got to go to presentations like this all the time and was so enthralled sometimes that I had to keep reminding myself to take notes and do my job. This guy's truly great. The audience is lucky.

Very good presentation spoke about latest space technology and lay persons could understand and be inspired. Great video.

I am so thankful for astronomers! I cannot explore every interest I have, but I can be joyful about the discoveries of others! Thank you!

Think I’ve learnt more in this one lecture than I have all year. Although we do have jet packs.

Wonderful to see this very large and deep subject delivered in such a plain and easy to understand format. It requires great skill to explain complex matters in a clear and simple manner. Congratulations to Bryan

This is a renowned scientist. Might not be a good talker to many people but he knows what's going on and all the basic knowledge and recent facts/findings. We are lucky to have experts like them to explore/prove what we can dream of. Enjoyed the summary/brushup of modern astronomy. G'day from Downunder.

I al an astronomer ana professor of astronomy and i must say that i seldom listened to such a motivating talk. I shared the link with my students of the introduction to astrophysics course. Congratulations bryan, for tour enthusiasm your humble attitude and tour scientific rigor

Bryan is a genuinely fantastic person, teacher, and speaker,

This is an inspiring, yet fact driven presentation! I appreciate the fact that Dr Gaensler summarized where we are on interstellar traveling and finding life in the universe rather than just discussing theoretical physics and maths! Thank you sooo much for summarizing it all for me!

I'm an author on the LIGO project. The explosion did not shake the universe afterward. The vibration is what's recorded just before the two neutron stars or black holes joined. This is the result of the two bodies rotating around each other as they get closer and closer. Right afterward, there is no vibration and no gravitational waves are produced from an explosion.

I am better off having seen this video. Thank you. That being said, when I was in high school a loooong time ago I was shown a picture of an atom and told this is what it looks like. Many years later...I came to understand that we didn't actually know what it looked like. I felt a bit betrayed, and then reflected back on the absolute arrogance of the establishment. Be vigilant. We don't know what we don't know so please be careful stating absolutes... Thanks again. Really enjoyed.

Professor Bryan, Outstanding, I really enjoyed your lecture.

This guy has a great way of lecturing! He is interesting and adds current hip stuff to show you what he means and he has a great flow! Amazing

I listen to a lot of documentories and this one is by far the best I have ever viewed. I learned meny things that I have pondered over and will watch it some more times to grasp some of the things I may have missed. Thank you for hosting this and binging it to the public eye.

Yesss, A movie of Rendezvous with Rama.... Really required.

Professor Gaensler nails it. Clear understandings of why we cannot do this or that - but maybe we could do this other. Neil de Grasse Tyson - there' s a new kid on the block. I have my science heroes - and Bryan Gaensler has just become a senoir contender. All the best to both of you - it's amazing work......
