We must always address the alien craft or whatever that have been sighted in our skies. Before moving forward.

Jack Large craft and alien beings have been addressed, but it is not news for people online or in schools and hospitals.

[@peterblake548]

This was an outstanding presentation. May I make a suggestion: The search for a Dyson Sphere is far more relevant as a tool to search for extraterrestrial life than looking for a Hello signal. The Hello signal works only in the here and now while a Dyson Sphere could detect a civilization that vanished a million or more years ago. What is our quest? Is it to talk with someone whose conversation occurs at the speed of light or to know that oumuamua may be a space junk relic of ancient aliens?

[@felipemachado963]

Great talk, made me think about things I never thought about before!

[@dhirajsuvarna4483]

Great speech. Gives me a different perspective of thinking.

[@thatdutchguy2882]

Most of us don't know or want to know our terrestial neighbours, imagine this of a cosmic scale. Some of our terrestrial neighbour are great people, some are weird, some are creepy, some are misunderstood and some are crazy, while others are dangerous to even cross paths with, imagine that on a cosmic scale. Let's keep a low profile and let keep the decision to alter that attitude case to case to highly educated highly peer regarded scientist, diplomats, military, security and governmental people from the entire globe.

[@jacke7695]

implying there are alien races that are more advanced then us, and them being a potential threat is a logical assumption. Keeping a low profile is a ship long sailed unfortunatly. We have been spamming light and radiowaves into space since 1888. And who knows what else we emit into space without us even knowing about it. (like we found out about our plastic islands in our own oceans last decennia)

[@thatdutchguy2882]

@@jacke7695 Really just the last 70 years and that's still not deep into space yet. Let's not put a huge amplifier on that and blast it trough space.

[@RobertsfunWords]

Don't worry about the neighbors. They aren't there

[@papinbala]

i think a dyson sphere is very primitive thinking. i think an advanced civilization would harness energy using some kind of advanced physics. i think they would be able to produce a lot of energy in small spaces. building dyson spheres is too much work. just like we have nuclear reactors, they might have the same things times a million.

[@adamblake9013]

papinbala - agreed. Same as the ‘laser propelled sail’ scientists propose as future interstellar probes. Yesterday’s ideas with modern tech.

[@thiennganguyen]

Kudos for the creative ideas in searching for ET. We will learn a lot more about our universe while searching! So I am glad to see that we expand beyond SETI

[@redhammer9910]

Interesting and it touches on my favourite topic, the unseen. I think the answer to how to recognise actual life is to devise a means to measure energy and at multiple types and frequencies thus like measuring the make up of a planets atmosphere in colour coded bars. Not just energy created by man made source's but energy created by thought, collective thought. A flock of birds all turn at the exact moment. In Australia near all species survive around pods. But every so often these pods come together to share their Gene pool.

[@RevJamesJones]

Thank You!

[@jmerlo4119]

Have you ever found yourself looking for your glasses, only to find out that you have been wearing them all along? Well, once upon the time, I found myself looking for myself and I discovered something really-really weird: "If there is an alien in the room, that alien can only be me" because everything else that I "see" is but one single unified being.

Space is big, even at light speed, we cannot leave our own galaxy, nor we even reach to the nearest star in human lifetime with tech we have, we know the peak of physics, and physics of observable universe. We have limitations, tht cannot be overcome. no matter how hard we try, accept the fact .

[@79Lexxus]

We think we know the peak of physics, but we dont by a longshot. Unless you think that space shuttles and cell phones etcetc were conceived 500 years ago, let alone 100

[@vidyasagar1861]

@@79Lexxus being optimistic is a good thing, you think of 500 years,when i am talking galactic scale, you better be optimistic. learning phy. started from 4th century, now we are at 21st, we reached peak of what can be achieved from it.

The Dyson sphere concept is ridiculous and primitive! There are better ways to extract energy from the ether (according to Nicola Tesla).

[@biologicalenergy955]

Better than others on alien search.

[@PlasticFate]

What a great speech

[@fardicus0004]

Just a thought, but I believe if there is extraterrestrial life, they will look exactly like us. The universe is built upon laws and patterns. Just as 2 hydrogen atoms and 1 oxygen atom combined make a water molecule, so too will life take the same shape when subject to the same conditions. Perhaps our own galaxy is flooded with life, but the distances are so great, and the technology so weak, that none of us can hear each other.

[@Charlesinfinite]

Absolutely no way possible that creatures from elsewhere look like us. Random mutation in DNA makes it impossible. Unforseen changes to the genetic code will change the course of evolution every single time. If you started life over on Earth with the exact same biology it would evolve differently.

[@andrewskratt9552]

interesting thanks

[@Uch1haSa5uk3]

we cant build a dyson's sphere. because the earth itself csn't fit around the sun. i mean where would we get that much materials from? EXACTLY

[@Beevreeter]

The concept of a Dyson sphere sounds patently absurd... the amount of energy and material it would take to build a structure with a diameter several times the magnitude of a star (so it didnt burn up) would probably be far in excess of anything any planet could ever produce.

[@lukeray1743]

Yes, to you it may sound that way, but if you understood anything he was saying, he was speaking of a civilization millions of years ahead of us technologically. Id say its very tough for small minds to comprehend.

[@Beevreeter]

@@lukeray1743 No, it's something small minds might not think through...

[@jimlouis783]

u r imagining for hominid, 2 eyed, two eared, two armed, etc. Earth fossils show five eyed creature, all that from 2 germs sticking together. Recall the search for the I Love Lucys, based on our hugely powerful signal transmitters. Those signal emitters lasted 100 yrs.

[@jackparker8686]

We must always always addressed to witnessed settings that apparently have occurred in our distant past to the present day.. Data for us to realize and make of it what we will. to skew our objectivity in such a way makes a force of science.. and we might as well hang it up.. Or call it Story Hour for the kids.

[@SyriusStarMultimedia]

Nature is waiting patiently for us to slip and fall. Every night she advances ready to take over. Never retreats. The things we are looking for are right in front of us.

[@hal7ter]

And many people have found them. Check out testimony videos that Dr Greer has uploaded to youtube. Many people have seen technological wonders that have arrived on Earth's shores, as well as ET beings who communicate by telepathy.

[@100consciouseternallightho6]

you are thinking "physical". Time is simultaneous. Time is a measure of focus. How long did someone focus their imagination on creating something? WE are holograms being created constantly within a holodeck. Energy is always what is being measured. Energy is always bursting forth as energy. It's the focus creating the image, that is what we see. In the book The Quantum World written by the physicist Kenneth Ford, I read that at the subatomic level photons and quarks and electrons seem to be all changing into each other at enormous speeds. Fire works of color. An illustration can be seen of what we look like as this fire works display constantly beaming out with light and colors from the center traveling at the speed of light, in the book Hands of Light written by the physicist Barbara Brennan.

[@Charlesinfinite]

A Dyson sphere is a ridiculous idea. I doubt civilizations that have the means to build something like that ever do. Energy can be obtained far simpler.

[@majorhowell1453]

If they are advanced their energy would be undetectable because it would match the energy in the universe. Also we are looking into the future. The planets are millions of years ahead of us. The planets look old and dead from Earth...

[@Charlesinfinite]

Ask yourself: why would an advanced civilization build an extremely complicated, massive, and very expensive Dyson sphere around there sun, when all the power you could need resides in the heart of Atoms? Why would a society darken their own sun so the animal and plant life on their planet suffers? The Dyson sphere is a fun idea but it's more impractical and ridiculous than actual screen doors on submarines.

[@PcGameGold]

Could you use the LIGO to search for Warp drives being used by Alien civilizations?

[@christopherleveck6835]

Why all the complexity when a simple pair of 3d glasses over the end of your telescope will do the same thing?

[@christopherleveck6835]

[@charleswest6372]

In decades yes

[@nataliakittou4587]

Why do you only think they are more intelligent than us? What if they still haven't created the technology that they can use to communicate? Maybe life is still evolving in another planet. And you only think about life that is similar to us but years ahead. When life evolved there are uncountable possibilities of how life could have evolved. So we only see it from our perspective.

[@JoshuaPappachen]

We are a young civilization. The universe has been around for far too long for another intelligent species to be less advanced then us. I watched another TedTalk posted about 3 months ago from today’s and it was amazing. The man explained how our civilization is in the adolescent stage and that if we were to meet another intelligent species they would be far more advanced then us.

[@Exploreraranyadev]

Exactly my point..

[@Exploreraranyadev]

[@decomp8641]

Power and control as all ways

[@Lok783]

We could do this now if we build enough drone like satellites and give them a spherical positioning guidance program so they manuver into position around the sun in a sphere. If we harness the power of our sun that would qualify is as a type two civalisation because building a dyson sphere around a star is one of the requirements to qualify. And it's extremely easy right now because of drone technology, The cost could be cheaper if you make the space drones as simplistic as possible but able to do the job We have drones already performing extremely complex grouped Arial feats as intertainmnet there's no reason we can't create a dyson sphere now

[@Charlesinfinite]

We have no technology whatsoever that could withstand orbiting the sun. Go look at the temp. A dyson sphere is an absolutely ridiculous idea. There are way easier ways too create energy. The immense size of the sphere and the engineering complexity coupled with maintenance and such make it a completely unrealistic idea. If you could manage to build something like this ( which would be pointless) it would be beyond difficult to do. It would require the invention of completely new technologies and would costs hundreds of trillions of dollars.

[@christernilsson6701]

Good talk but one thing strikes me. We have no idea how common life is in the universe. We start to understand there are plenty of planets out there, maybe a billion billon as Erik tells us. But so far we have not detected life anyehere but on earth! As long as we do not understand the necessary conditons for life to begin we are just guessing. But also if we do find microbes on Mars e.g. what are the chances that intelligent life evolves? So far we can only guess here as well. When trying to put numbers on those two guesses (life at all, intelligent life) we can get any result from 1 to billions of civilisations out there.

[@wolfwarrior7499]

I think in all truth we shouldn't be searching for extraterrestrial intelligence and by doing so giving away our position opening up ourselves for an attack.

[@davidturner6212]

gww... Is there a galactic wide web, that can be accessed and discovered using the right hardware and software? A galactic internet that uses something other than radio waves? Erik Zackrisson said to look for technology that's different than our own. Advanced civilizations would be connected via some kind of galactic internet, wouldn't they? If someone found it, they would also learn a great deal about these so-called aliens, who could be human beings in and from other worlds.

Even they exist to close per example 200 y.l. .. with our radio signals we have to wait 200 years to responds and over.. Our ( human been) first radio signals are a bit more than 100 l.y. away.

[@philrilp6711]

Glad he's making the case for the failure of SETI to detect any proof of et as well as the dyson sphere and the need to think outside the box and look for anomalies is good, but like most in academia he's not even discussing the anomalies that are happening within our atmosphere or low earth orbit or the dark side of the moon. Just think how much more we would know if the govt didn't create the stigma through ridicule and disinformation or even discreditation for all of academia to operate under effectively controlling any real independent scientific consideration for research on the topic for fear of ridicule or reprisal. As a result despite the recent push to destigmatize still the focus is on the grand scale of needles in haystacks rather than our own backyard, with a few exceptions like Gary Nolan and Avi Loeb and others over the past 5 - 10 years or so but this has been happening in our current state of tech advancement since ww2 and prior to that since antiquity. Just saying, they're already here and that would be nice to see academia taking a refresher course on this and get up to speed on it in their approach to this.
