We now know of thousands of planets orbiting other stars. But we know of only planet that hosts life - the Earth.
Most scientists think that life elsewhere in the Universe is likely to exist, but so far there is no evidence that extra-terrestrials exist or that they have visited us. However, we can search for signs of life on distant planets and we are even using radio telescopes to look for messages sent to us by extra-terrestrial civilisations. In this talk Tim will discuss the latest science behind the search for alien life.
Tim is a Professor of Astrophysics and an Associate Director of Jodrell Bank Centre for Astrophysics at The University of Manchester.
Tim’s research concentrates on the study of exploding stars using telescopes around the world and in space, working across the spectrum from radio waves to X-rays.
Tim is passionate about astrophysics and its power to inspire. Well known for his regular contributions to science on TV and radio, he is Jodrell Bank’s host for the hugely popular BBC TV Stargazing Live series and has a monthly space discussion programme on BBC Radio 5 Live.

In 2014, jointly with Professor Teresa Anderson, he was awarded the Kelvin Medal of the Institute of Physics for innovative public engagement, and in 2016 he was elected as President of the UK’s Society for Popular Astronomy.
This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at ted.com/tedx

Any intelligent being that has developed the technology to travel the immense distances between habitable bodies in space--and nonliving drones with the ability to interact with and learn about interstellar or intergalactic space during the voyage would probably be what is traveling those distances--would most likely not be impressed with the human race. Humans might be given about as much respect as humans do to bacteria.

@Clout Lord That would only make sense if we were 'alone' in the universe. My statement was based on the presumption that we are not alone, meaning that God does exist and is either good or bad. I have reason to believe He is good. Though I do agree that the concept of God not existing would be quite terrifying, which is certainly something that kept me up at night as a child.

@Clout Lord As I said, my statement was on the presumption that we are not alone in the universe. If you want to base an argument on the opposite assumption then that is your affair. I do not believe personally that it is possible to have no God, but my belief itself is not enough to remove impossibility. It is either impossible or not regardless of me. Good and bad are only human concepts in the subjective sense, meaning that we as humans, with often clouded judgement, change our minds out of convenience, needs, and wants, as to what is good or bad. Someone will justify murder to themselves if it benefits them and suddenly it is a good - or even on a societal level. However, good and bad in the objective sense is certainly not a human construct because it goes beyond our blindness. Objective morality has only come to us by means of religion, which the religious believe to be sent by God himself. Considering how self-denying all of God's laws are, if we are talking about the Christian faith, it would seem unlikely to me to be a human construct. No one in the right mind would deny themselves pleasure (if on a surface level seems to harm no one) unless they were told it was wrong by something beyond themselves, and unless they thought there were consequences not only in this life but in the next. An example of this would be fasting. Many religious have fasted rigorously, not for health benefits, but to deny their own flesh in order to become holy. There is no way that humans, who love pleasure, would ever come up with such a thing unless necessary for health reasons (other than a small percentage of crazies). And the argument that all religious are insane does not quite work either for obvious reasons that I hope need not be explained. Maybe He's in another galaxy? You clearly no nothing of the concept of God, who is beyond time and the material universe. Why do skeptics always mock faith? That is a rhetorical question by the way. If you wish not to believe then that is your choice. But there is no need to mock me with such a ridiculous premise of God. If God were inside space and time then He would not be God obviously, at least not the Christian one.

"It is the only substance that WE know about" Only substance that we know about? I'm pretty sure water is not the only substance we know :) Other than that, every substance stable enough and present in our galaxy would also be present on Earth. Earth is not an isolated system. Matter from our entire galaxy is constantly bombarding Earth in the form of dust and little rocks. When large enough comet hits a planet, some of the matter of that planet is ejected into space. There's not a substance in our galaxy that hasn't been shared across its entirety. Every planet contains some trace amount of matter from every other planet in our galaxy. Is that like a news flash for you or what?

Real lucky he gauged it well, could you imagine if he pulled out probability charts and spectroscopy images of other stars during planetary transit.

"It needed to be said again." True. Also, 40 years ago the chorus was 'give us the technology and we will find the evidence.' Well, we are developing the technology, so it is valid to ask 'where is the evidence?' Absence of evidence is not evidence of absence, but maybe it hints at it.

I think if there is life out there it is very spread out. Because in the history of the earth (the best place we know of for life to have started) life started once in 5 billion years. It was nearly wiped out several times and life evolving beyond single celled organisms took a very long time to start. There may also be a great barrier. So I'm not to optimistic.

The Drake Equation only calculates how many civilisations we should be able to detect. I've seen and heard several figures thrown around, someone even suggested that even with the lowest possible "settings" the equation came out with around 10,000 civilisations out there in our Galaxy alone. With all that possible life you would think we would be able to hear something and yet our heavens are silent. So we are left with a few possibilities: A) We are indeed alone in the universe. B) We are the first civilisation to reach our current stage of development - A very scary thought! C) Other Civilisations have developed different methods or more direct ways of transmitting information. D) Other civilisations know something we don't and have adopted radio silence in an effort to hide their existence.

I wonder if there were 6 Earth like twins that had our exact level of technology that all would pop up evenly around the Universe. For discussions sake, lets also assume they are in similar types of galaxies and locations within that arm of their galaxy and orbiting sun like stars like our own, etc. Most of them would likely be expanding away from us also as the universe itself expands. My question would be, how long would it take for us to detect a signal coming from their planet if we knew where exactly to look?
@skytrainii8933
@skytrainii8933 7 жыл бұрын
John, let me make one small yet very significant change to your first statement. The Drake Equation only calculates how many civilisations we should be able to detect if all the assumptions the terms represented are true and correct. As we learn more and more about our local solar system and our local view of the universe, we necessarily make changes to the values of the term and even the terms themselves. As we view more and more exoplanets, we will have to make changes to the equation. Right now, however, the equation does not represent our current evidence and observations. In other words, the equation says one thing and we have nothing. But we must keep looking because what we find will point to the truth; whatever that truth may be.

We are NOT alone, the nearest star with habitable planets is 137,000 years away with current tech. If we all evolved at a similar rate as other planets in our galaxy then no one has travelled to another planet, have we????? No one has the tech developed to travel that distance yet.

Narrow band of time to develop technologically from Stone Age to where we find ourselves today. So Stone Age lasted 3m years until 4000 years ago when we started working with metal. Electricity hasn’t been around for very long. Flying has only been around for 100 years and 60 years after it was invented, we were walking in the moon. It’s exponential. We also exponentially develop weapons to use against each other. One exponential curve will negate the other. If good tech wins, our technological development will accelerate. If the bad technology wins, our civilisation will become the myths carved into stone for future civilisations to discover. Other worlds would have a similar path. They’d only need to be 300 years further along the good exponential curve to be so far advanced we’d call them aliens.

I was not interested or cared if other life exsisted until this happened to me. Driving from one small farm community to another passing open fields ready for planting season. I saw a unusually large metallic oblong object on the ground about 100yds from road in a field. My thought was this is part of a construction project. A oil or gas tank going into ground, but unusually large. 15 to 30 minutes later passing thru same area object was gone.( i know from experience how to load and unload heavy object on to flat bed semi's). My point is, it would be impossible for large moving equipment to get into area, lift the object, load it on flatbed, secure it for movement and all vehicles involved leave the area without me seeing them come into or leave out of area in less then 30 min.
