interface and the core autonomy mission manager out of that to give the system a very kind of predictable look and feel to the person. called Centaur , which is an optionally piloted aircraft.
everything that goes near it gets sucked in. to go to Alpha Centauri with a Saturn 5 rocket, it would take 70,000 years to
pair of binoculars to see it. It's called Proximus Centauri, and it is just a hair closer to us than the two stars of Alpha Centauri. Anyways, in 2016, it was announced a group of astronomers found an exoplanet with the Doppler method around Proxima Centauri, our nearest neighbor in the galaxy.
It's a chip with a parachute, inflated by a bank of laser beams, which would accelerate it to 20% the speed of light. And it would reach Alpha Centauri in 20 years. And so we are talking about the first microchip starship to take us to the heavens.
Mine wasn't. good drow ranger. Did you also use two centaurs ? Probably. A little panther with you.
for planets. So let's imagine for a moment we could transport ourselves to one of these, not the TRAPPIST ones, but some planets orbiting a slightly bigger star. But other stars like Proxima Centauri b, it's flaring like dozens of times a day, basically.
And so this is a wonderful branch of mathematics which sort of reveals the richness and power of the subject. Maybe we'd actually get to Alpha Centauri.
It's always one of the beauties of astronomy as you have pretty pictures to show. This is a galaxy called Centaurus A and not too far from us, it's kind of a messy galaxy but I think you can see that on top and bottom there's sort of strange plumes coming out and there are two, there's a supermassive black hole deep inside this galaxy, And, in fact, we've discovered, the Milky Way is not alone in having a supermassive black hole
of Alpha Centauri. Anyways, in 2016, it was announced a group of astronomers found an exoplanet with the Doppler method around Proxima Centauri, our nearest neighbor in the galaxy. And what was even more exciting is this new planet which has been called without that much creativity Proxima B. The new
It's massless. And that's essential to make electromagnetism a long-range force. The electron here repels an electron in Alpha Centauri.-- OK-- or anywhere in another galaxy. And the reason is, because the photon is massless, it can carry an arbitrarily small amount of energy.
Mark Hoppus: Talk to my attorneys. he's pretty rad. Tom DeLonge: Was that Centaur ?
Faster speed comes with stronger propelling, which is enabled by injecting more fuels per unit time to boost. We computed how much energy it would require to travel to Alpha Centauri in 1,000 or 10,000 years and we need to inject the entire solar system per second. Pretty much you have to use all the solar system you pass by as the source of energy. Also we need materials that can endure such a high speed.
married on Friday at the sun Horizons Convention Center in Sarasota Florida Rabbi Tom goldwitz officiated the couple in the online virtual world known as second life Mr soda's screen character or Avatar is a four-legged Centaur with a Rippling human torso in the arms and head of James Bond actor Daniel Craig the instant I saw him I fell in love
really don't. We know a lot about it, but really understanding it, not so much. But Newton thought that time was just universal for everyone, so my time, your time, some person's time on Mars or on Alpha Centauri, everybody experienced time the same. What Einstein showed was that that wasn't the case, that different people moving at different speeds with respect to one another experience time differently, which is absolutely a mind-blowing concept. Now, most people think that Einstein then said, well, he invented spacetime, that,
How far away is that? Four and a half light years. And if you take a look at the Alpha Centauri system, the closest system to the Earth, you have uh red red stars that could could have life on them. We're not sure.
view like this one. So, this is the famous southern cross. We have the constellation of Centurus that kind of surrounds it. And over here is a very famous pair of stars actually called Alpha Centauri that are often said to be the closest stars to the sun. Actually, that's not exactly right. There is a
much less conspicuous star over here, a little red star that you actually can't see by eye. You need at least a good pair of binoculars to see it. It's called Proximus Centauri, and it is just a hair closer to us than the two stars of Alpha Centauri. Anyways, in 2016, it was announced a group of astronomers
But one light year is equal to about six trillion miles. That's really far. And the next closest star to our solar system is Proxima Centauri, and it is 4.3 light years away. And in miles, that's about 25 trillion miles.
Give me one example. Well, uh, for example, take a look at Alpha Centauri, the closest star system to the planet Earth, right? How far away is that?
And that's about 10 trillion miles. The closest planet that is potentially habitable and that it orbits its star at a region where it could have that climate is Proxima Centauri b, orbiting the closest star to us.
the news, it was probably accompanied by this dramatic image right from the planet's surface, right? We see these mountains. Uh we see Proxima Centauri in the distance. You can even see the two stars of Alpha Centuri further away.
for planets. So let's imagine for a moment we could transport ourselves to one of these, not the TRAPPIST ones, but some planets orbiting a slightly bigger star. And I just listed three, for those who would read the news or notice that last summer there was one announced around Proxima Centauri b, that's our very
the Heisenberg uncertainty principle. And if it can exist for an arbitrary long time, it can travel from here to Alpha Centauri before it's absorbed. So the fact that electromagnetism is a long-range force is uniquely related to the fact that the photon is massless, in this picture.
And then the nearest other star, which is still pretty near, Proxima Centauri, is two thousand miles away.
You can have leaves that are photosynthesized, that are photosynthetic and are totally black which I thought was a lot of fun. One last step back. Alpha Centauri, this is the nearest
