Two problems with expecting signals from exoplanets are noise and periodicity. First, after a typical human made radio signal travels about 50 light years the signal to noise ratio becomes so weak that the noise swamps any chance of detecting a meaningful signal. Second, planets rotate about their own axis as well as rotating about their sun. So a signal emitted at night is not visible to the cosmos on its day side, and a signal emitted in summer is not visible to a signal emitted during another season. I've never seen a comment on this limitation. Surely, people smarter than I are aware of these issues... Aren't they?

I believe the chances of life beyond Earth are virtually 100%. Single celled organisms and the like are probably pretty common, maybe even in our own solar system. But I feel like complex life forms, much less highly intelligent life, are probably exceedingly rare. There's just an unbelievable amount of hurdles to overcome. Just my feelings 🤷‍♂️

With the amount of time since the Universe began, however long that has been, there has been plenty of time for many different intelligent forms of life to have evolved.

​@@yppykyathere's even been enough time for them to colonise the entire galaxy. So the question is where are they? Imagine being an intelligent species but your a whale. How do you build rockets? Imagine you are on a large planet, how to escape the extra gravity? I think species with the opportunity to build advance tech and go into space have got to be incredibly rare. If not unique. Maybe we should try not to fk it up?

There are an estimated 2 trillion galaxies in the universe and nearly 4,000 solar systems just in our own galaxy, and the universe continues to expand. Even if the odds are exceedingly rare relative to what we expect, 'rare' could still include some unfathomable number of intelligent life forms in the context of the entirety of the universe.

Fact is, how do we know what to look for? Chances are that things would be very different from a different species

Gotta be something out there.

WHY DO I KEEP FALLING ASLEEP TO Y'ALL'S DOCUMENTARIES!? For real, last night a was laying on my couch, finished the Mr. Beast stranded at sea video, I dozed off and woke up around 4AM to some really nice aircraft carrier documentary (algorithm took over, my history is all boats - specially military ones) I then fell asleep again. But for the last month everytime I fall asleep in couch and let YT autoplay there's always at least 1 Spark Doc in my history I feel bad because someone obviously put a lot of hard work and production into it

Amateurish execution,. at 7m55s we have klms for kilometres, instead of km simply

11:36 It should not be surprising that we have found more Neptune and Jupiter size planets. Just looking at our Solar System, the two groups are half the planets, plus their large size makes them easier to detect.

Perhaps per galaxy and there are many there is only one technological civilization in each. If this is so we will never know for we would never receive a signal from that distance.

I'm interested in this video but the music is so irritating that 10 minutes is all I can take.

What amazes me is there is some guy out there 100 million miles away, eating a cheese sandwich, wondering if there is life on other planets.

Ive never doubted we are not alone. I am hopeful to see true open first contact. I encourage those lucky enough to be a part of the awakening of this world to keep pushing the limits and keep me posted lol

This video came out 7 hours ago and spark lists that we know of 3,700 exoplanets..... It's actually 5,837 known exoplanets as of today... Soooo, was this filmed last year or the year before and just released now ??

they probably got the rights to release a bunch of documentaries. I made the sustainability documentary Antimatter Future in 4k in my channel modern up to date dark matter etc... like the patents from the US Navy UFOS how they fly. Tom DeLonge helped get us the UFO videos, I show the science how they fly legit some of the science used to be public knowledge but scraped from the internet think about it antimatter propulsion would be most efficient, why isnt anyone reporting on it? i showed revolutionary science to make antimatter cheap which debunks the argument its too expensive to try i even show science of warp travel and revolutionizing current travel using the vortex for more speed efficiency! science references on the website

It uses AI data (ChatGPT) and it is updated only up to mid 2021

Considering there are more (so far) super-earth sized exoplanets, would the inhabitants of such planets even try to develop a space program, where the greater gravity would make leaving the surface almost impossible? If we look to popular literature, we could see planets in the situation of Asimov's Nightfall, where a multi-sun system makes night observation impossible, they don't know or even suspect the universe exists. Similaly in Adams' Hitch Hikers Guide, a planet whose solar system in a dust cloud, again making the universe invisible

Dr Odele Staub, What a beautiful accent ❤ Would love to be in her gravity 😊 n mind ✌🌏

The ads on this video feel outdated.

Just in my lifetime ive seen the advent of cellphones and the internet - the idea that mankind did not evolve for over six thousand years is absurd

Its wonderful to see some amazing minds looking out and discovering where mankind will go to next .. beyond the short-sightedness of believing we will all take holidays on Mars in 2080 😂

The truth is, there is life on other planets in every direction. looking straight out from any point on earth

2018 there is no newtonian theory it is Galileo's and Kepler's theory

Absolute zero chance, the furthest any human being has ever been is the International Space Station.

Let’s put an end to this question. The chances are 100%. SETI is looking, and when it finds anything, they’ll tell us. End of story
