That's only true as long as you are accelerating. the only time the span of time seems longer is the flash that occurs after you have accelerated to a new position. If when you get to that new position you stay still then the subsequent flashes will once again resume a 1 second frequency. Constant acceleration is required for the frequency to "appear" to continue to increase.
Is it possible to "anchor down" in space and just let the galaxy pass you by? Or are we stuck on the same piece if stretching time as the matter around us?
a doubt on the temperature of the universe : that is, here the sun is treated as the heater and the room is treated as the universe(from here on i shall write it as the space ) . here it goes . he said that heater isnt on enough time so that the room isnt at a temperature higher than its previous temperature . but if the same heater is on for sufficient time then the heat of the heater spreads through out the room there by raising the temperature of the room .(same as we do in winters to keep our room hot ) . the room will be at a temperature say 'x' the low is the 'x' the more time heater takes to raise the temperature of the room . now let me come straight to the point the sun surface temperature is 5,778 K . so how cold enough is the space (universe )(here i am not referring to the entire universe becoming hot because its damn big but a part of it becoming hot i mean think upto Saturn or the next planet ) so that it is not still hot even the sun (alias the heater )is in 'on state' for thousands of years . what is the temperature of the universe so that even the sun is not being able to warm it up . extension : if we think this, there are many stars that produce heat( starts produce heat ,but i simply used the sentence like that ) in the universe but still the our universe or space is so cold outside . what if there are no heat sources(stars) in the universe then what will be the temperature of the universe
The reason that the space is so cold while the sun is so hot is that space doesnt have any molecules, what we call space is complete emptiness, it doesn't contain even a tiny gas molecule. Thats why, beams from the sun can't hit the molecule and transmit its energy because there is no molecule
The topic was interesting and although nothing new, these were great examples to get the idea of how simple questions work. The talk was given in a way that bore me though. I dislike it when people talk slowly to try and captivate the audience. Only talk slowly if you can't speak quickly or have something really complex to explain. Just my opinion.
*This universe definitely had a beginning, and I believe that God created it. He's the beginning and the end, and to tell you the truth, we're not made up of atoms, electrons or nutrons, but instead, we are made in God's image. Scientists are way off track about the universe being billions of years old, because the Earth is only about 6/7,000 years old. There is definitely a Creator!*
Mayukh Bose Yes. In his example about Einstein and him in the Opera House, they were accelerating at the same rate. Einstein's clock would not run slower "because he was closer to the earth" if they were accelerating at the same rate.
Nilguiri if they are accelerating closer to speed of light, light would need more time to reach him thus slowing down the time for the observer. Think of the acceleration of the operahouse as a race with light. The faster you travel the slower time passes.
I was wondering if anyone else picked up on that! Since they are both accelerating at the same rate, the light would still take 1 second to travel between the two. One of the many facts of relativity that makes it so interesting. In this scenario, the only thing that would change the relative time between the two observers would be if one was closer to an object with a lot of gravitational force.
is no one else going to address how good looking this guy is?!?
This dude spoke in a way that actually had an impact. It was different but it was easy to follow and easy to digest.
New favourite TED talk. Very interesting.
I didn't even read the title of the video. I just saw that this guy was cute and now I'm watching it

I am using this in my classroom again this year, thank you!
If you want to understand something complex, ask a simple question. If not, ask a simple person.
Interesting n informative talk. Thank you, bless you. All your dreams come true.
Wow, this is all fascinating stuff...more talks about this please!
Profound insights given in this short video.🎉
Your words have answered my question about the stars that move in oddly ways. Thank you. ... My question is how do earth get it's size?
Is it possible to "anchor down" in space and just let the galaxy pass you by? Or are we stuck on the same piece if stretching time as the matter around us?
Sound of Now is not No. Now is different from No. Brilliant TED Talk though. What a young Scientist!
Mind blown 😳
Bowties are cool! 😉
Great Ted talk. one problem; can't concentrate
a doubt on the temperature of the universe : that is, here the sun is treated as the heater and the room is treated as the universe(from here on i shall write it as the space ) . here it goes .
he said that heater isnt on enough time so that the room isnt at a temperature higher than its previous temperature . but if the same heater is on for sufficient time then the heat of the heater spreads through out the room there by raising the temperature of the room .(same as we do in winters to keep our room hot ) . the room will be at a temperature say 'x' the low is the 'x' the more time heater takes to raise the temperature of the room . now let me come straight to the point
the sun surface temperature is 5,778 K . so how cold enough is the space (universe )(here i am not referring to the entire universe becoming hot because its damn big but a part of it becoming hot i mean think upto Saturn or the next planet ) so that it is not still hot even the sun (alias the heater )is in 'on state' for thousands of years . what is the temperature of the universe so that even the sun is not being able to warm it up .
extension : if we think this, there are many stars that produce heat( starts produce heat ,but i simply used the sentence like that ) in the universe but still the our universe or space is so cold outside . what if there are no heat sources(stars) in the universe then what will be the temperature of the universe
he is talking about the force
Dodie was right...this guy is hot
The reason that the space is so cold while the sun is so hot is that space doesnt have any molecules, what we call space is complete emptiness, it doesn't contain even a tiny gas molecule. Thats why, beams from the sun can't hit the molecule and transmit its energy because there is no molecule
That's not correct! There is thermal radiation, which allows objects to transfer heat through vacuum.

Great video
This was really good. But for some reason, I can't stop thinking about Daisy Ridley when I see his muscles on his face moving like that haha.
I am your FAN here!
Oh he cute
Thank
"Light is just an electromagnetic field." Well that's debatable isn't it?
Why you should never trust a fart? Best Tedx talk ever.
Are thought experiments valid experiments?
why is he so hot?
is this a ted talk or is this a physics lesson? But he's cute though .
chrisse tyler Why not both?
its not easy to ask "Simple Question"
Champagne and cornflakes.
Are those ghosts neutrinos?
Sorry for that but this guy reminds me christian priests from my childhood. His voice makes me sleep.

mmm, do you have any proof? It doesn't sound like a convincing argument to me!
According to the King James Bible.
Dinosaurs?
I'm not entirely sure but I think he got relativity very very wrong
no, he nailed it
Mayukh Bose Yes. In his example about Einstein and him in the Opera House, they were accelerating at the same rate. Einstein's clock would not run slower "because he was closer to the earth" if they were accelerating at the same rate.
Mayukh Bose It depends on where you stand... ;)
