Will humans ever travel to other galaxies?
Intergalactic travel for humans is therefore possible, in theory, from the point of view of the traveler.
Traveling to the Andromeda Galaxy, 2.54 million light years away, would take 28 years on-ship time with a constant acceleration of 1g and a deceleration of 1g after reaching half way, to be able to stop..
How far have we seen in the universe?
30 billion light-yearsToday, the most distant objects we can see are more than 30 billion light-years away, despite the fact that only 13.8 billion years have passed since the Big Bang. The farther a galaxy is, the faster it expands away from us and the more its light appears…
What is the farthest planet we know of?
New technique finds farthest known planetThe newly identified planet, known as OGLE-TR-56b, is an amazing 5,000 light-years from Earth, easily setting a new distance record. “The new planet is 30 times farther away than the other extrasolar planets,” Sasselov said. … DETECTIVE STORY. … NEW WAVE OF DISCOVERY.
How old is our galaxy?
13.51 billion yearsMilky Way/Age
What is the oldest star?
HE 1523-0901 is the oldest known star in our galaxy, the Milky Way. The star’s estimated age is about 13.2 billion years.
Does the universe have an end?
The end result is unknown; a simple estimation would have all the matter and space-time in the universe collapse into a dimensionless singularity back into how the universe started with the Big Bang, but at these scales unknown quantum effects need to be considered (see Quantum gravity).
Can Hubble see the moon?
The Hubble telescope is known for its views of faraway galaxies, distant planets, dying stars, and black holes. … Since ultraviolet light is blocked by gases in the Earth’s atmosphere, ground-based telescopes can’t use it to observe the lunar surface.
What is the farthest object in the universe?
In December of 2012, astronomers announced a Hubble Space Telescope discovery of seven primitive galaxies located over 13 billion light years away from us. The results are from survey of the same patch of sky known as the Ultra Deep Field (UDF).
What is outside the universe?
In our own backyard, the Universe is full of stars. But go more than about 100,000 light years away, and you’ve left the Milky Way behind. Beyond that, there’s a sea of galaxies: perhaps two trillion in total contained in our observable Universe.
How old is our universe?
13.8 billion yearsUniverse is 13.8 billion years old, scientists confirm Scientists estimate the age of the universe by measuring its oldest light.
How old is a God?
I’d even say there was no God before the end of the Neolithic age, and that means God is roughly 7,000 years old.
