@restitvtororbis5330 10 месяцев назад

@@joyeternal2314A prediction/theory is not a discovery regardless of whether it turns out to be true. Einstein also THEORIZED that light was influenced by gravity, but we didn't 'know' it was true until it was tested a few years later. Even though all the physics research for over 100 years theorized that gravitational waves SHOULD exist, we didn't know for sure until LIGO was able to detect them and turn theory and prediction into scientifically tested and proven knowledge. Nobody ever says Einstein or schwarzschild 'discovered' Black holes even though they suspected them on paper because they were both dead long before they were observed, and this is a similar case. As for the recent gravitational wave discovery, yes LIGO was able to prove that they existed at all a few years ago, but now it was able to detect that there is also a 'background' of gravitational waves everywhere, like the sea, thus the reason that comment mentioned now being able to see waves in the 'sea of space-time'. Detecting one gravitational wave made the existence of the gravitational wave background a certainty, but until we were able to measure it we couldn't consider it to be a 'discovery'.

So, in general, the way interferometers work- the longer the arms, the greater the sensitivity. Now, there is also a potential dependence on the wavelength of light and the synchronization of clocks on the instrumental arms. This being said, LISA should be more sensitive to small events and potentially quite directional depending on the exact configuration eventually implemented.

@michaelginever732 11 месяцев назад

Sub's for Europa and Enceladus. Will be more difficult of course, but not impossible. The solution may be to equip them with some sort of nuclear powered ice melting 'nose'. The hole will probably just freeze up behind the vehicle but that is good because we have seen the water being ejected when the ice is breached. We wouldn't want the sub' just "spat" out of the hole the moment it hits the liquid water.

Hi Fraser. When gravitational waves pass through us, as they cause to stretch and squeeze everything in their path, could they cause any changes in us? I understand that the space itself is getting stretched and contracted.

@chris-terrell-liveactive 10 месяцев назад

Thanks for another excellent QnA Fraser and have a great break. I have a question about possible "other earths" , some of the simulations that are shown have an Earth sized planet with much smaller seas, few or no oceans, and I'm curious how this would affect the habitability and likelihood of complex life arising, due in part to a reduced capacity to circulate heat around the planet, especially if it was also tidally locked to its star. Could this be another factor in the checklist for likely life/complex life (let alone technological intelligences)?

@idodekkers9165 11 месяцев назад

Hey Fraser when lets say a black hole merger happens, are the gravitational waves like ones in a pond? where there are quite a few until the interference subsides, or is there one big wave and that's it?

Dude! You totally copped out on that last question. Define negligible. Really, really do love your channel

Negligible depends on the masses of the objects interacting. For Earth and the Sun, it could be a few km across. For the Sun and Jupiter, dozens of km across. For Earth and the Moon, hundreds of meters across.

@YTEdy 11 месяцев назад

I think the Lagrande mass range is only applies to the Sun and the Earth, not the Earth and the object at L4 and L5. In theory, a very massive object could sit at one or the other, but not both, even up to or above the mass of the Earth, but as long as it's much less massive than the Sun. I think the ratio from memory is 26-1, so even a Jupiter mass could work. They'd be co-Lagrange objects to each other. In a 3-body model, this would be stable indefinitely, though with eccentricity and orbital perturbations, probably still not a good idea.

@robethendricks3523 11 месяцев назад

You may have covered this so excuse me. If there is a space time that can transmit waves, gravity waves, what is the medium that transmits those waves? Your answer can’t use space time as the medium because would be circular.

@isaackitone 11 месяцев назад

Since we are orbiting around the milky way, couldn't we eventually end up on the same side as the great attractor in, say 100 million years? Or is the milky way also orbiting around that area and we will always be on the opposite end of it?

@gptiede 11 месяцев назад

Yes. The Earth takes about 225 million years to orbit once around the center of the Milky Way galaxy, so in about 112 million years, the Great Attractor will be opposite the center of the Milky Way in Earth's sky, and it will only be a few 10s of millions of years before Earth will have completed enough of an orbit for the Great Attractor to be visible as it "comes out from behind" the center of the Milky Way. Unfortunately, both time scales are way too big for humans to wait.

@olliverklozov2789 11 месяцев назад

Yes. The milky way is spinning like a top so in 100 million years a different part of the universe will be blocked from our view. We are being drawn towards the great attractor (attracted) but that would take billions or trillions of years.

@isaackitone 11 месяцев назад

I'll wait. If it's just 10s of millions of years. That's not too much time for me.

@jimmytittle4848 10 месяцев назад

So I have a question..... Off subject a bit. But I'm curious how I have heard it said that one of the issues with light speed is that whatever ship you would be traveling in would have mass and "drag". So, if this is true, how is it possible for an interstellar meteor that's said to be traveling for billions of years hit our atmosphere at 130,000 mph? Wouldn't that same "drag" have caused it to stop eventually?

@terrybradford3727 11 месяцев назад

(Dagobah Segment) Have an awesome break/vacation. A potential question for next season, to keep with the Lagrange point motif. Would the Lagrange points be a great place for space mining? Maybe not our, but Jupiter sounds like prime real estate. Stable and predictable orbit, the mass similar to the asteroid belt. Of course, I also thought slamming an asteroid int the moon to mine it was a good idea, lol. EDIT: A reference to when this was on Google hangouts, lol.

@IDoNotLikeHandlesOnYT 11 месяцев назад

I'm not Fraser, but I'm guessing they'll just use the same laser ranging system they already have for science for formation maintenance too, along with Earth-based Doppler tracking and maybe Earth-based time-of-flight ranging. IIRC, they're going to be equipped with FEEP thrusters, the most precise (in terms of minimum impulse bit) kind of thruster yet invented. The main perturbations will probably be from solar radiation pressure and Earth/Moon gravity, which can both be modeled pretty well. Any rocks larger than dust that hit them would probably just destroy them, but fortunately there aren't many of those-even the main belt is safe to fly through without having to avoid anything.

Once we get space telescopes past Neptune, we can use the Sun asca gravitational lense. At that time we'll be able to see distant stuff at great detail. Give us a hundred or so years and we'll be there. Once we start building huge telescopes on the far side of the Moon, we'll be getting real pictures of exo planets. We're only decades from that happening.

@CarFreeSegnitz 11 месяцев назад

Moon telescopes have drawbacks. The Moon has gravity that telescope mechanisms have to work against. Mirrors are heavy and so are the frames that carry them. There’s an upper limit before both sag against the gravity. No matter where you site a lunar telescope half the sky is denied to you. The Moon gets in the way. Free-floating space telescopes are the way to go. No gravity to warp mirrors or frames so we could build them as big as we want. But, of course, any telescope on the Moon or free-floating will be subject to micrometeorites. Free-floating telescopes could be aimed at any point except straight at the sun, the whole sky is available.

What happens when iron meteors hit Jupiter? Has any been able to estimate how much iron has collected from them?

@gptiede 11 месяцев назад

As any meteorites fall into Jupiter they are accelerated to faster and faster speeds by Jupiter's strong gravity as they fall. As a result when they get to the atmosphere of Jupiter they are going faster than 60 km/s (about 135,000 miles per hour) and so when they hit the atmosphere they are vaporized into gas in a tremendous explosion. This was directly observed for the pieces of Comet Shoemaker-Levy 9 as they hit Jupiter's atmosphere back in 1994. This would happen for an iron meteorite just as it does for a comet due to the very vast collision velocity. The iron molecules would eventually sink into the planet and become part of Jupiter's core. I am not aware of any model of the amount of iron that has fallen into Jupiter, but the average composition of infalling material will be the same as Jupiter's composition, except for Jupiter's hydrogen and helium, so the core mass would very slightly increase but not enough to make any significant differences.
