What if the laws of physics were different? Neil deGrasse Tyson and co-hosts Chuck Nice and Gary O’Reilly answer grab bag questions with astrophysicist Charles Liu about alien heists, gravity, and space exploration.
Is there a way to manipulate time? Is time a constant? Learn about time as a dimension, scimitars, and time as a resource. What would happen if advanced aliens could steal the sun? Would we fall into orbit around Jupiter? We consider the possibilities…
Which laws of physics could we change that would have the least effect on everyday? What if the Hubble constant was different? Or if Newton’s laws were slightly tweaked? Plus, learn how one body of mass can have multiple strengths of gravity. When will Earth’s tectonic plates stop moving? We also discuss why we go to space instead of the many unexplored parts of the ocean.
How does weather affect a football match? We explore the impact of weather on sports and how Neil, Chuck, and Gary would do in a survival situation. Is it faster to run or dive to a base in baseball? Find out all about physics and astrophysics in another Grab Bag Cosmic Queries episode!
00:00 - Grab Bag
6:35 - Time as a dimension
12:01 - Could an advanced alien steal the sun before the other side of Earth can notice?
18:05 - Which of laws of physics could you change and have least effect on everyday?
23:46 - Could a body of mass have two different strengths of gravity?
26:35 - How long before techtonic plates stop moving?
29:50 - Why don’t we have a deep sea base?
33:50 - How does the weather affect a football match?
40:20 - How expertise in physics might help with survival?
46:40 - Is diving or running faster?

I can't believe that I'm about to out-geek Charles Liu. "Double-edged sword" simply means that something "cuts both ways"; it has both positive and negative consequences. This phrase is attested to the late 15th century. Charles's story of Richard and Saladin is from Sir Walter Scott's _Tales of the Crusaders_ ca. 1825, but it reminds me of the Japanese story of Muramasa and Masamune. In a challenge to see which swordsmith made the most perfect blades, they both placed their finest swords in a river. Every leaf that floated near Muramasa's sword was drawn toward it and cut; every leaf that floated near Masamune's sword passed by completely unperturbed. Presumably, this was because Masamune's sword was so perfectly honed that it didn't disturb the current of the water flowing past it. Of course these stories are both apocryphal; Richard and Saladin never actually met and Muramasa and Masamune were not contemporaries. They're great stories nonetheless.

My interpretation of the "double edged sword" is that a sword with two sharp sides can also cut the user. If your sword is struck with enough force it can come back and cut you if the backside is sharp, or when your swords are locked and the other person pushes harder. It's beneficial because you can swing it either way, but also, it can come back and hurt you too.

My 7th grade shop teacher (1968) (a time when there was still routine concern about nuclear war and its results) advocated the file as the "one tool to have" in event of survival needs. It can be used as a saw, with the tip deliberately worn down to thinness it can be used as a screwdriver, and - unlike the pocket knife espoused by Chuck, et al - it is has enough mass to be used as a hammer. Oh, and it can be used as a file, too. I admit, as a 66 year old man, to this day I keep a file or two handy, beyond what's in my toolboxes and tool drawers. Hey. Ya never know. : )

I'd like to say that recent testimonials from pilots involved innthe Gimbal incident reveals that there were 5 other craft present flying in a V formation at slightly different altitudes. These craft we visually identified at relatively close range as dark grey to black cubes with clear spheres around them and were approximately between 15 and 30 feet in diameter. The corners of the cubes were touching the inside of the clear spheres they were inside of. No discernable means of propulsion moving at 450 knots against the wind . Chris Leto has the goods about this in his youtube channel. Keep up the good work fellas 👏

These four guys are so great together. Question, though, on the Sun being stolen... I thought that gravity affects at the speed of light so it would take each planet a different amount of time to go tangentile (my word). So is it possible for smaller planets to begin orbiting nearby bigger planets before the gravity effect stops affecting Neptune.
@natelewis8259
@natelewis8259 Жыл бұрын
I don’t know if that delay would have much of an effect in this regard. While there is a difference between when each planet would lose the effect of the Sun’s gravity, this difference is still determined by the speed of light. So although Mars may begin to move tangential to its original orbit while Jupiter or Neptune are still affected by the Sun’s gravity, Mars is moving so slowly in respect to light that it will have barely moved closer to the larger planets by the time they too start to move tangential to their orbits. It would be interesting to see the time it takes light (and therefore gravity) to propagate through the solar system in relation to the speeds of the planets. But if I had to guess, I would think the planets would seem frozen in place, hardly moving from their original positions by the time light travels from the Sun to Neptune. Edit: I just did a quick search and it only takes about 4 hours for light to reach Neptune from the sun. I don’t think the inner planets would get that much closer in that short of a time.

Or, Earth loses the Sun's attraction and heads in the direction slightly ahead of where Jupiter currently is. Well, no I guess not. Like you say, Jupiter will lose it's attraction and go tangental long before Earth approaches Jupiter.

If Jupiter is moving faster than earth there is an option the Jupiter will eventually pull earth or Jupiter is at more than. Earth escape velocity and earth won't catch up.

8:10 In Larry Nevin's Known Space books there is a technology called a stasis pod. Inside the pod time doesn't pass, even as time continues outside the pod. A person inside the pod will not experience any time passing, meaning if you go into the pod, you will come out an instant later for you, even if millions of years have passed around you. The technology is used more than once in a crashing spaceship to protect the passengers and crew. A stasis field is generated inside the pod and then turned off after the crash. The crew experiences an discontinuity, in one instant they are flying along without any problems and the next instant the ship has crashed, bat as the crash is over, no one is hurt.

The final discussion on sliding into first base was correct when coming from home and incorrect after reaching first base and leading off toward second. In the latter, diving for first base would be more advantageous if the throw from either the pitcher, catcher, or a fielder catching a fly ball is designed to pick off or double up the runner.

12:28 Speed of information question. 1st Mercury, then Venus, and then Earth would start traveling on paths tangent to their defunct solar orbits in that order. Then Mars, the outer planets and solar system objects would do the same in their turn as the information wave hits them. Since bodies closer to the Sun orbit faster than bodies farther out, these inner bodies could collide with some of the outer bodies given the right initial trajectory when the Sun is suddenly stolen by aliens. The gravitational influence of all the planets would become more significant with the sudden loss of 99.8% of the solar system's total mass. Sounds like a great SF concept.

Neil said things would be flatter after returning from the bottom of the ocean. But the pressure is being exerted from all sides upon the object -- so wouldn't it be shrunk in all directions and not just one?

Charles really honed his soundbite and the way he speaks to audience.. It was awful before to hear him talk but now he is just so much more interesting.

12:01 - Could an advanced alien steal the sun before the other side of Earth can notice? Wait a minute, Charles hinted the change would be instant but space can't move faster than the speed of light so wouldn't even the orbit of the Earth not be felt until after the 8 minutes?

Not sure if this has been asked and answered already. When discussing the consequences of an alien civilization stealing the Sun, it was established that it will take 8 minutes for the side facing the sun to receive the information that the event was occurring due to the time it takes for light to travel, but at the same time we would feel the gravitational effects instantly. Does this mean that the speed of gravity is faster than the speed of light?

If you changed the 2nd law of physics such that every action had an opposite, but not exactly equal, reaction, then wouldn't that mean that some mass and energy could either be created or destroyed? I.e., wouldn't that require a change to the 1st law? Wouldn't we have to ask what happens to the diminished or extra force in the reaction? Of course, thinking about the question with our current frame of reference might be a confounding factor. How could we actually think about it objectively?

would the gravitational pull of the sun release instantly or is that delayed too?

well it would reshape spacetime instantly, causing gravity to have an instant effect on everything around the sun, but it would still take a while before any noticeable changes to be observed. kinda like a train startimg to move in motion (or stop) that because of the trains mass it would take a while before it gets up to full speed (or stop)

That story about the swords... No slashing sword is all that good against an armored opponent. What you want is either blunt damage or piercing damage, in the form of estocs, spears, daggers for piercing and hammers, maces, and the like for bludgeoning.

That question after 7:25 just proved against your tired old theory of relativity with respect to time dilation. Finally someone asking the real questions here.
