She'll make .5 past light speed.

她能实现0。5级的超光速。

" Advances in medical education are now happening at light speed."

“医学教育正在以光速发展。”

That glow is the echo of matter moving faster than light speed.

这种光是物质以比光速更快的速度运动的回声。

That is until we discover a way to travel at or near light speed.

那是在我们发现以光速或接近光速旅行的方法之前。

$300 and I'll throw in my original 1979 mattel millennium falcon with real light speed sound effects.

300美元再加上我的1979年的原版千岁鹰，有真的光速音响效果哦。

Because Earth is a small enough place to where light speed basically does mean the same thing as instants.

因为地球是一个足够小的地方，在这里光速基本就意味着瞬间。

If the charged particle is moving slower than whatever light speed is in that material, we can't really see that ripple of light.

如果带电粒子的运动速度比材料中的任何光速都慢，我们就看不到光的涟漪。

But without a medium, what is light's speed relative to?

但是没有介质，光速相对于什么？

If you could travel at light speed where would you go?

如果你能以光速旅行你会去哪里？

Number two, you really kicked it into light speed at the end there.

- 第二，你真的在​​最后把它踢到了光速。

That is until we descover a way to travel at or near light speed.

直到我们发现一种以光速或接近光速旅行的方式。

But when we look out to space, over astronomical distances, to the stars, planets and galaxies beyond, then light's finite speed has profound consequences.

但当我们仰望天空观察远在天文距离之外的恒星 、行星和星系时，光速就会产生重大的影响。

But! Special relativity tells us that the light's speed was still exactly c.

但！狭义相对论告诉我们，光速仍然恰好是 C。

But special relativity tells us that when it comes to light, speed is always constant.

但是狭义相对论告诉我们，当涉及到光时，速度总是恒定的。

Then we'd build a very large firehose and blast it at light speed towards the Sun's core.

然后我们会建造一个非常大的消防水带，并以光速将其喷射到太阳的核心。

This is the number we think of as the speed of light, c, but, more accurately, this is just the speed light travels in a vacuum.

这是我们认为的光速，c，但是，更准确地说，这只是光在真空中传播的速度。

So based on the theoretical limits that we've studied so far, there is a possibility that one day we might be able to travel at light speed.

所以基于我们到目前为止所研究的理论极限，有一天我们或许能够以光速旅行。

But when you move out beyond our scale, light gets slower and slower to the point where it quickly seems to more resemble a snail rather than you know light speed.

但当你移出我们自身的范围，光会变得越来越慢，以至于它很快就似乎更像一只蜗牛，而不是你知道的光速。

Ideally, we would be prepared the next time, not only to develop a vaccine in light speed, but also to to make and distribute the vaccine in light speed.

理想情况下， 下一次我们会做好准备，不仅要以光速开发疫苗， 还要以光速制造和分发疫苗。

This means not going for downhill KOMs when you're in a bunch. This means not trying to be as fast as you can off the lights, speeding away and dropping the entire bunch.

这意味着当你在一群人中骑行时，不要去当下坡王。这意味着不要试图尽可能快地关掉车灯，超速离开并甩下整个车队。
