Hence, the “edge” of the universe could be moving faster than the speed of light, and a “beam” of light couldn’t reach it! geometer said: Hence, the “edge” of the universe could be moving faster than the speed of light, and a “beam” of light couldn’t reach it!Apr 26, 2004.
Is there light at the edge of the universe?
At distances of 31 billion light-years, corresponding to a time of just 550 million years after the Big Bang, we reach the edge of what we call reionization: where the majority of the Universe is mostly transparent to optical light.
What happens at the edge of the universe?
Since these distant galaxies are receding away from earth at a speed faster than light, the light from these galaxies will never reach us, no matter how long we wait. The edge of the observable universe cannot keep up with the expansion of the universe so that many galaxies are eternally beyond our observation.
How long does it take light to travel to the end of the universe?
In metric units, that’s about 300,000 kilometers per second. How long does light take to reach us from familiar objects?Other Galaxies. Object Time for the Light to Reach Us The Sun 8 minutes Jupiter 35 to 52 minutes Pluto 5 1/2 hours (on average) Alpha Centauri (nearest star system) 4.3 years.
What is the farthest we can see into space?
“From previous studies, the galaxy GN-z11 seems to be the farthest detectable galaxy from us, at 13.4 billion light-years, or 134 nonillion kilometers (that’s 134 followed by 30 zeros),” Kashikawa said in a statement.
Does the universe go on forever?
Many think it’s likely you would just keep passing galaxies in every direction, forever. In that case, the universe would be infinite, with no end. Scientists now consider it unlikely the universe has an end – a region where the galaxies stop or where there would be a barrier of some kind marking the end of space.
What is beyond the end of the universe?
But “infinity” means that, beyond the observable universe, you won’t just find more planets and stars and other forms of material…you will eventually find every possible thing.
What is outside the edge of the universe?
Outside the bounds of our universe may lie a “super” universe. Another theory is that we are creating space as our universe expands. Outside this expansion lies a higher dimensional space-time universe which we are unfolding into. Since it is higher dimension, we cannot see, detect it, or comprehend it.
What is at the end of space?
Many think it’s likely you would just keep passing galaxies in every direction, forever. In that case, the universe would be infinite, with no end. Scientists now consider it unlikely the universe has an end – a region where the galaxies stop or where there would be a barrier of some kind marking the end of space.
Does anything travel faster than light?
Albert Einstein’s special theory of relativity famously dictates that no known object can travel faster than the speed of light in vacuum, which is 299,792 km/s. Unlike objects within space–time, space–time itself can bend, expand or warp at any speed.
Will we ever travel at light speed?
So will it ever be possible for us to travel at light speed? Based on our current understanding of physics and the limits of the natural world, the answer, sadly, is no. So, light-speed travel and faster-than-light travel are physical impossibilities, especially for anything with mass, such as spacecraft and humans.
Will the universe end?
Astronomers once thought the universe could collapse in a Big Crunch. Now most agree it will end with a Big Freeze. Trillions of years in the future, long after Earth is destroyed, the universe will drift apart until galaxy and star formation ceases. Slowly, stars will fizzle out, turning night skies black.
What is the oldest thing in the universe?
Astronomers have found the farthest known source of radio emissions in the universe: a galaxy-swallowing supermassive black hole.
Can you see the flag on the moon through a telescope?
Can you see an American flag on the moon with a telescope? Even the powerful Hubble Space Telescope isn’t strong enough to capture pictures of the flags on the moon. But the Lunar Reconnaissance Orbiter, the unmanned spacecraft launched in 2009, is equipped with cameras to photograph the moon’s surface.
What is the biggest thing in the universe?
The largest known ‘object’ in the Universe is the Hercules-Corona Borealis Great Wall. This is a ‘galactic filament’, a vast cluster of galaxies bound together by gravity, and it’s estimated to be about 10 billion light-years across!.
Does space have a smell?
In a video shared by Eau de Space, NASA astronaut Tony Antonelli says space smells “strong and unique,” unlike anything he has ever smelled on Earth. According to Eau de Space, others have described the smell as “seared steak, raspberries, and rum,” smokey and bitter.
Do wormholes exist?
Wormholes are consistent with the general theory of relativity, but whether wormholes actually exist remains to be seen. Theoretically, a wormhole might connect extremely long distances such as a billion light years, or short distances such as a few meters, or different points in time, or even different universes.
Does the Galaxy have an end?
That’s accounting for the increase in star formation when the Milky Way and the Andromeda Galaxy collide around that time. Thus, some 19 billion years after the Big Bang, the Milky Way will begin its slow but inexorable decline — and, a trillion years from now, the end will come as its last star fades from visibility.
Why can’t we see beyond the edge of the observable universe?
Anything outside of that radius of 46 billion light-years is not visible to Earthlings, and it never will be. That’s because the distances between objects in the universe keep getting bigger at a rate that’s faster than the light beams can get to Earth.
Does the universe have a center?
According to all current observations, there is no center to the universe. For a center point to exist, that point would have to somehow be special with respect to the universe as a whole.
What is inside a black hole?
HOST PADI BOYD: While they may seem like a hole in the sky because they don’t produce light, a black hole is not empty, It’s actually a lot of matter condensed into a single point. This point is known as a singularity.
