Tyrannosaurus would have had an extremely large retina over which they could collect those photons.

霸王龙应该有着非常大的视网膜才能使它们接收这么多光子。

If the smooth surface absorbs the photons instead of bouncing them back, there's no reflection.

如果光滑的表面吸收光子，而不是将它们反弹回来，那就没有反射。

Light is made up of particles called photons.

光由叫做光子的粒子组成。

That energy is emitted as photons of visible light.

能量以可见光的光子形式发射。

That gave electrons something to do instead ofalways intercepting photons.

这就让电子有事可做，而不总是拦截光子。

Such particles could include photons or microscopic pieces of matter.

这种粒子可能包括光子或微小的物质碎片。

In the study, a quantum computer prototype " Jiuzhang" was established and helped detect up to 76 photons.

这项研究建立了量子计算机原型“九章”，并帮助探测到多达76个光子。

Uh, that device, there, will measure the photons that return and let us see it on this computer.

那个装置能测量返回的光子 我们能在电脑上看到。

And radiation composed of innumerable particles of light, also known as photons.

以及由无数光的粒子形成的辐射，也被称为光子。

The gamma ray burst released photons carrying a record amount of energy.

伽马射线爆发释放了携带创纪录能量的光子。

These photons fill all of space, trillions passing through your body every second.

这些光子占满了所有的空间。每一秒就有几万亿个光子穿过你们的身体。

So even if it tried to emit radiation, the photons would fall back.

就算这个物质试图散发辐射，光子也会被重力拉回来。

So what you're seeing is that last orbit of photons.

所以大家看到的是光子的最后轨道。

You know people are exposing their eyes to this stream of photons from these objects.

看手机时，人们的眼睛总是暴露在这些电子屏幕的光子流中。

That gives the leaf ample opportunity to absorb every photon of light passing through.

这样叶子就有充足的机会去吸收阳光传递过来的每一缕能量。

The photons don't change every halide.

光子不会改变所有的卤化物。

The Sun merges atoms and radiates photons away that carry energy into the solar system.

太阳会合并原子并辐射出光子，从而将能量发送进太阳系。

So researchers built a photonic chip—a computer chip that uses photons instead of electrons.

所以，研究人员制造了一个光子芯片——这种计算机芯片用光子代替了电子。

That means just 6 out of every 1000 photons manage to escape.

这意味着每 1000 个光子中只有 6 个成功逃逸。

So photons that get in can't get out.

所以进去的光子出不来。
