Curious layman

A pretty obvious question, but are you the only one who uses your search engine? 

I use Bing, I have about 4 different devices that automatically sign in when I turn them on.

Fascinating.

Apparently prisoners from Missouri state. A well known institution known as 'boys town' that has had several books and movies made about it.

To Paris, of course!   I can't imagine why  I would want to go to a place where I can't even breathe!

Were inside a Delta flyer. You didn't think we were planning to walk there did you? 🙂

Easy, Pluto and it's five moons

Always been fascinated by this mysterious dwarf planet. Next stop Titan.

Even if humanity stopped emitting greenhouse gases tomorrow, Earth will warm for centuries to come and oceans will rise by metres, according to a controversial modelling study published Thursday.

Atheist. 

I understand very little about science, even less about religion. It all comes down to trust.

Would it be feasible to create (say via gene editing) a human being who would have a memory so good that he would remember every second of his life and experience it like a movie/

Some people can already do this: https://en.m.wikipedia.org/wiki/Solomon_Shereshevsky

Solomon Shereshevskii had a memory so perfect that he could recall every minute of his life in graphic detail. This fantastic capacity was further distinguished by the fact that he could “feel” images, “taste” colours, and “smell” sounds.

Its not like a super power though,

Another problem Solomon faced was that he often found it difficult to recognise people he had know for some time, or recognise whose voice it was on the telephone. Solomon’s awareness of detail was so acute that slight changes in a person’s facial colouring or voice made it difficult to recognise them. Most of us do not even notice such small changes of complexion or vocal sound.

I imagine the death of someone close would be hard to deal with. Must be extremely difficult to move on if you can remember everything like it just happened.

My new employer makes communication cables for BT, Orange etc.., so they haven't shut down once, in fact they've won loads of new contracts because of this.

We've had 12 positive test results in the last fortnight. I'm a smoker who lives with someone with cancer, so I'm pretty worried right now to be honest. 

Listening to my co-workers during breaks fills me with horror sometimes (conspiracys) it seems inevitable that someone from our team will catch it.

Due to my smoking I think my chances of surviving it will be low. So yeah, a little worried right now. 

What would the temperature of the surrounding water be? Would it turn to steam due to friction? 

If a diver was passed by this supersonic sub, and wasn't killed by the shock wave, would he be boiled alive?

Don't forget the pope

On the contrary, I think he's turning out to be a great pope.

Pope-same sex marriage

Venezuelas Maduro, citing pope, asks congress to consider same sex marriage 

Just wondering, if I was traveling at Mach 50, would the g-force  kill me?

Spacecraft during re-entry only get up to ~ mach 25, and even at that speed, the air is heated to a plasma state.  Craft like Apollo and Soyuz use ablative shields that burn off to deal with it. And this is in the upper part of the atmosphere, where the air density is very low.

So it's more of a material science problem then, and fuel too probably.

Does science know the limits for heat resistance in materials, in the same way we know what the limits are for energy capacity for batteries?

In physics, I would say that the limit is c.

Yes, but not through earths atmosphere in a plane though. Makes me think of the relativistic baseball. Lol.

Apologies if this is in the wrong space, I wasn't sure if this should be in engineering or physics.

Is there a limit to how fast we can fly through the air. For example, will we one day have planes that can fly at mach 50?

There are about 1,000 star systems where aliens, if they existed, could be watching us from afar, new research suggests.

Those 1,004 star systems are in a direct line of sight to our planet, and close enough to us that they could not only detect planet Earth, but also chemical traces of Earthly life.

What has Robert Stephenson got to do with it??

Is this question to me?

who mentioned Robert Stephenson?

There just my signatures, People I'm interested in. Nothing to do with the question.

Thanks, I read something on Quora which gave the impression it would allow huge technological advances. Thought I'd check here to see if it were true. 

What will it enable us to do? 

Would the effects on humanity be dramatic?

A friend sent me this link and I'm curious to find out if what she claims is legitimate. This is a recording that makes some pretty incredible claims. What does anyone else think?

link removed per Rule 2.7

It's 2 hours 16 minutes long!

A quote within the first minute: "Everything I know comes from non human sources". I stopped listening after this.

This recording explains the following:

1. The Direct Sensory System: The human body’s ninth sensory system responsible for the ability to understand energy as a language.
2. The Non-Cellular Bandage: A living biomedical bandage that will heal a wound three times faster leaving little to no scar. Invented through information provided by the language of energy.
3. Autohemotherapy: A daily therapy that will prevent and cure most known diseases and viruses including COVID-19. Perfected through information provided by the language of energy.
4. Reprogramming: A one-on-one therapy to remove fears, phobias and cure many mental disorders including P.T.S.D. This information was provided through the language of energy.

I think the person making these claims is talking out of their ass.

  The "Gallilean theory" says that velocities add as $v_1+ v_2$... Relativity theory says that the velocities add as [tex]\frac{v_1+ v_2}{1+ \frac{v_1v_2}{c^2}}[/tex].    If the velocities are small then [tex]\frac{v_1v_2}{c^2}[/tex] will be negligible and that the two formulas give the same thing to within measurement error.  If [tex]v_1[/tex] and [tex]v_2[/tex] are close to c, as [tex]v_1= v_2= 0.6c[/tex] then [tex]\frac{v_1v_2}{c^2}= (0.6)^2= 0.36[/tex] so the velocity of the bullet relative to you is [tex]\frac{0.6c+ 0.6c}{1+ 0.36}= \frac{1.2}{1.36}c= 0.88c[/tex].

Good answer, next time someone asks me this question, I'll know what to say. 😁
