Can you see Earth in the past from space?

Can you see Earth in the past from space?

No. Because you cannot reach the speed of light, even if you had started travelling away from Earth the day you were born, you could never catch the light carrying the image of your being born.

How far back into space can we see?

The Hubble Space Telescope can see out to a distance of several billions of light-years. A light-year is the distance that light travels in 1 year.

Can we see further back in space than we can in time?

It is not that we are seeing farther back in space than we are in time. Instead, it is that space and time are related, the universe is expanding, and the effects of the expansion are cumulative: they affect the light traveling through the universe during every step of its journey.

What would happen if you Travelled to the end of the universe?

Dark energy could still evolve, leading to a Universe that might either recollapse in a Big Crunch, expand forever, or speed up in its acceleration and eventually tear even the fabric of space apart in a catastrophic Big Rip. The different ways dark energy could evolve into the future.

Can we see the past when we look into space?

The answer to the question is yes. If you were to magically (yes, magic would be needed) appear far away from Earth and you got there in less time than needed by light, you would look back at a Earth in the past. Understand that the reason we see the past when looking into space is not an advanced idea.

How far into the past can we see the Earth’s past?

If that mirror was on Pluto, you could see about 13.4 hours into Earth’s past. If you are relying on hearing, you hear an event at 30 m away about 0.1 s after it occurs. That is why runners often watch the starting pistol at an event, because they can see a more recent picture of the past than they can hear.

Is it possible to travel 65 million light years to Earth?

In theory, yes. In practice, it’s much harder, because the earth is so small and 65 million light years is a long distance. For perspective, all the visible stars in the night sky are within about 1,000 light years of us. The Milky Way is about 100,000 light years across.

What if we could resolve the details on Earth?

If you were able to somehow resolve details on Earth you may be able to see objects. Hypothetically, you will be looking at Earth as it was in 615 A.D. This happens also due to difference in spatial frames between Earth and Kepler-425b. This doesn’t mean that you are looking at the “past”.
